Grumman Goose converted to turboprop

My favorite airplane at Oshkosh so far… a Grumman Goose converted to PT6 power. The owner was gracious and let our 7-year-old get into the cockpit and cabin, but I didn’t dare ask him how much it had cost to re-engineer the beast.

In one small area of the event we saw four different sizes of Grumman seaplanes: Widgeon, Mallard, Goose, and Albatross!

And if you thought landing a seaplane was challenging…

Should the Nord Stream pipeline be considered an engineering wonder?

The seafloor pipeline from Russia to Germany has been in the news lately (see “U.S. urges Ukraine to stay quiet on Russian pipeline” (Politico): “The Biden administration is asking an unhappy Ukraine not to make waves, as it nears Russia-Germany pipeline agreement.”; I guess Joe Biden finally found a pipeline that he could love! (compare to “Keystone pipeline canceled after Biden had permit blocked” (USA Today)).

I wouldn’t have thought that a 760-mile seafloor pipeline could be done as a practical engineering matter. From Gazprom:

The outside surface of pipes has a special anti-corrosion concrete coating. The concrete coating is made of high-density iron ore, which is crushed, mixed with cement, and put on pipes. As a result, pipes are wrapped in spiral reinforcement, which is filled with concrete, and then treated with steam in special tunnels for 24 hours. The concrete coating helps meet several challenges at once. Firstly, it keeps the pipeline on the seabed, preventing it from drifting off with undercurrents. Secondly, it serves as insulation, protecting the trunkline from outside mechanical damage.

The genius of Russian engineering? Wikipedia says that it was actually the Italians who figured out how to do this:

On 19 March 2007, Nord Stream AG hired Italian company Snamprogetti, a subsidiary of Saipem, for detailed design engineering of the pipeline. A letter of intent for construction works was signed with Saipem on 17 September 2007 and the contract was concluded on 24 June 2008

Readers: Should we be awed that this is working at all? Is the best analogy the Portuguese and other early European trips around the Horn of Africa to India and China? It is tough to believe that the sea voyage was actually more efficient than the overland one, but a lot of middlemen were cut out.

(My Ukrainian friends are not fans of this Biden Administration decision, but it won’t cost Uncle Joe any votes because these non-virtuous immigrants to the U.S. already disliked Biden/Harris for their Bigger Government policies.)

  • “The Security Implications of Nord Stream 2 for Ukraine, Poland, and Germany” (Wilson Center): … repairing the current Ukrainian-Polish pipeline would cost around €6 billion. The construction of Nord Stream 2, however, would cost €10 billion. Experts believe that Nord Stream 2 is diverting gas from the preexisting Ukrainian-Polish pipeline, meaning Europeans will receive the same amount of gas, if from a different source. … completion of the pipeline would see the European continent increase its dependence on Russian gas. If tensions were to rise between Europe and Russia, Russia could turn off the pipeline, leaving millions of Europeans without gas. Second, Europe’s reliance on Russian gas would present Russia with the leverage to further meddle in the affairs of its neighbors without consequence. Third, the new pipeline would divert the flow of gas from Ukraine and Poland, leaving these two countries to face a substantial revenue loss. They would also be forced to pay higher gas prices.

Garmin autopilot protects Bell 505 helicopter pilots and passengers

Readers of this blog will have noticed that I’ve always got my panties in a twist regarding how dumb human-scale helicopters are compared to $500 DJI drones. A bit of untwisting from Garmin:

Garmin today announced that the GFC™ 600H flight control system has received Supplemental Type Certificate (STC) approval for installation on the Bell 505 helicopter, … The GFC 600H provides a number of helicopter-tailored safety features, including attitude hold with speed stability, the innovative hover assist mode, Garmin Helicopter Electronic Stability and Protection (H-ESP™), dedicated return-to-level (LVL) mode, as well as overspeed and low-speed protection, and more.

… automatic altitude leveling airspeed and low G protection.

Thanks to the innovative hover assist mode, the system can also automatically detect a hover condition and allows for flight control inputs to help maintain position over the ground. In addition, when equipped with the optional yaw axis control, the GFC 600H can hold heading in hover.

In other words, with this system installed an airplane pilot can hover a helicopter without any training!

GE: Proud to be years late

EAA AirVenture (“Oshkosh”) starts today. Given how slowly everything in aviation moves, Oshkosh is more of a social gathering than a trade show, but manufacturers do like to announce their progress here.

Earlier this month, I checked in on the General Electric “Catalyst” Advanced Turboprop engine. This competitor to Pratt’s PT6 (first flight: 1961) had been scheduled to fly in 2018 (November 2017 press release). It still hadn’t flown. I went to GE’s aviation blog to see if they offered any explanation for being years behind schedule. The top of the blog was “A Conversation With Carmen Campbell, GE’s Transgender Advocate for Europe”:

They say it’s easy to stand with the crowd but it takes courage to stand alone. This Pride Month, the GE Aviation blog celebrates Carmen Campbell, the first person to ever transition at GE’s Grand Rapids, Michigan, site and now GE’s Transgender Advocate for Europe.

Campbell, originally from the US, is an advanced lead systems engineer based in the Cheltenham, UK Power Distribution & Controls business. She is passionate about using her experiences to help cultivate a safe and supportive workplace for her transgender colleagues.

This role sits within the transgender advocacy group, which is part of GE’s Pride Alliance. We run education sessions, work with GE to develop policies around transitioning, and provide support for transgender people within the business. The role is relatively fluid and it’s important to note that we are a resource for everyone at GE, transgender or not.

One of the areas I’m most proud of is the work we have done on the GE transition toolkit, which summarizes GE policies, provides helpful suggestions (like how to develop a communications plan), goes in to site specifics like bathroom usage, and lists who to contact for further support.

There has been some progress in the last 20 years, most notably the step change in legal representation. Gender reassignment became a protected characteristic under the UK’s Equality Act 2005, for example, and it was stipulated that people should be treated in accordance with their acquired gender.

However, I do think we’ve casually been sliding backwards since then. Certain groups, individuals and media outlets have been chipping away at the trans community, trying to roll back the trans rights that we’ve fought so hard for. Indifference can also be an issue.

“Casually sliding backwards”? Maybe the LGBTQIA+ engineers at GE can slide backwards far enough to catch up to where Pratt was in 1961. Then they could put their turboprop on an airplane and fly!

#Science says masks are the best thing that ever happened to children

Parking a warm saliva-soaked mask in front of a child’s mouth all day isn’t the most obvious way to protect children from exposure to bacteria and viruses. And “Experimental Assessment of Carbon Dioxide Content in Inhaled Air With or Without Face Masks in Healthy Children” (JAMA Pediatrics, June) heretically suggested that children might be better off with an unobstructed airway.

All is right with the world once more, however. The paper has been retracted by the editors. The only question is why humanity didn’t discover the healing power of full-time mask-wearing centuries ago.

Is the best way to #StopAsianHate to stop Asians from succeeding?

“Boston Overhauls Admissions to Exclusive Exam Schools” (New York Times, July 15):

After five and a half hours of emotional discussion on Wednesday night, the Boston School Committee voted unanimously to overhaul admissions to the city’s three selective exam schools, opening the way for far greater representation of Black and Latino students.

The new admissions system will still weigh test results and grades, but, following a model pioneered in Chicago, it will also introduce ways to select applicants who come from poor and disadvantaged neighborhoods.

Under the new system, the applicant pool will be divided into eight groups based on the socioeconomic conditions of their neighborhoods. The admissions team will consider applicants within each group, admitting the top students in each tier in roughly equal numbers.

The Groupthink aspect is interesting. The high quality schools had been operating for 100+ years in a particular way. Not a single committee member thought that continuing with the proven system made sense!

What kind of high-scoring young learner is this new policy designed to exclude?

Asian American students were 29.3 percent of Boston Latin School’s enrollment in 2020, despite making up 9 percent of students in the school’s district.

On the one hand, this might seem odd. Leaders who bravely place #StopAsianHate signs on their lawns and/or bravely tweet using the #StopAsianHate tag are trying to exclude Asians from elite schools. But perhaps there is no inconsistency. Suppose that the sign-gooder believes that the reason Asians are hated is because Asians are more successful than comparatively stupid and lazy white people. In that case, it would make sense for him/her/zir/them to place obstacles in Asians’ paths so that they can’t succeed as much. If Asians can’t get into the elite schools they won’t provoke as much envy and therefore the mission of #StopAsianHate will have been accomplished.

If masks are optional, why are there under-nose masks?

I was in the Tysons Corner, Virginia shopping mall last week. Masks are no longer required in Virginia. Governor Blackface (he’s sorry about his past racism, but not sorry enough to resign and let a Black person take the governor job?) rescinded his mask order in May (see “Virginia drops mask mandates, but not everyone is quick to give them up” )(NBC)).

Some folks wandering the mall were, nonetheless, wearing masks. This didn’t surprise me, but I was surprised by the fact that quite a few of those who were masked were wearing their masks under their noses. If you’re part of the Talented Tenth who believe in masks forever, wouldn’t you also be careful to wear a mask correctly? (i.e., make sure all of the aerosol virus goes out the sides!)

The photo below, taken July 13, 2021, shows the chin diaper and under-nose styles in front of a store owned by my favorite American growth company (#StocksForTheLongRun!).

Over in the U.K., 40 percent want masks forever… (I wonder how many support under-nose masks forever…)

Meanwhile, Facebook tells me (July 15) that even the smallest person can be a pandemic-ending hero by adding a frame to his/her/zir/their profile picture:

Despite this energetic effort, the propaganda ministers in Washington, D.C. are not satisfied. NYT:

President Biden’s surgeon general on Thursday used his first formal advisory to the United States to deliver a broadside against tech and social media companies, which he accused of not doing enough to stop the spread of dangerous health misinformation — especially about Covid-19.

The official, Dr. Vivek Murthy, declared health misinformation “an urgent threat to public health.”

Facebook, Twitter and YouTube said that they had taken steps to crack down on misleading health information, in line with their coronavirus misinformation policies. All three said they had introduced features to point people to authoritative health sources on their platforms.

YouTube said in a statement that it welcomed many takeaways of the surgeon general’s report. Twitter said it agreed with the surgeon general’s society-wide approach and welcomed his partnership. A person with knowledge of the matter who spoke on the condition of anonymity said officials with the company met with the surgeon general’s office on Monday.

Great Society history lesson III

Continuing our look at Great Society: A New History, a book that chronicles the biggest shift since the 1930s in Americans’ relationship to government. (See Great Society history lesson II also.)

The idea of reparations is not a new one…

In 1963 the Urban League’s Whitney M. Young had proposed a Marshall Plan for black Americans, including direct payments to poor families to lift them over the poverty line. Thomas Sowell, a graduate student, was concentrating on his PhD, an essay on the pre-Keynesian economist Jean-Baptiste Say. But Young’s idea irked Sowell so much that he’d written a letter to the New York Times. The reaction to such a Marshall Plan, Sowell wrote, or to any other offer, would be the same from black Americans as it was from whites. “People who have been trying for years to tell others that Negroes are basically no different from anybody else,” Sowell said, “should not themselves lose sight of the fact that Negroes are just like everybody else in wanting something for nothing.”

White people loved higher minimum wages just as much back then as they do now:

Black and white youth unemployment had run about the same until the middle of the 1950s, 8 to 11 percent. But when Congress raised the federal minimum wage by a third in 1956, unemployment rose far higher among black teenagers than among whites, to 25 percent. … the economist Milton Friedman was reaching a conclusion: those who were supposed to benefit from a minimum wage were nearly always actually hurt, as “the intended beneficiaries are not employed at all.” Friedman the following year would slam the minimum wage as “the most anti-Negro law on our statute books.”

Then as now, government handouts ideally are about the same as the median wage:

But the newly generous War on Poverty welfare benefits actually encouraged men not to work, adding to the ranks of unemployed. With the average family welfare check between $ 177 and $ 238 a month, and wages at $ 220, the commission concluded that “the financial incentive to find work may be either negative or non-existent.”

(See “The $600 Unemployment Booster Shot, State by State” (NYT) and “Work Versus Welfare” (CATO, 2013))

Certainly there shouldn’t be a housing shortage in the U.S. at this point…

But the scaling and the speedups were also evident at home, in the new HUD building, and a nationwide building program. For housing, Johnson promised $7.5 billion, more than nine times the poverty program’s annual budget that first year. The American people were, Johnson said, “strong enough to pursue our goals in the rest of the world while still building a Great Society here at home.” In 1966, everything could be, had to be, big. Even before Watts, Washington had made up its collective mind to put its formidable shoulder into a second Great Society drive, housing. Since Watts, that commitment had only hardened. The Administration would supplement, and sometimes steamroller, its flawed program, community action, with construction. Nobody could disapprove of infrastructure improvement, politicians told one another.

And we should have all of the infrastructure that we need too. at least in the cities that Big Government favors:

Johnson laid out his second Great Society in his State of the Union address in January. The president would support construction everywhere. More than $ 2 billion of the funds would go to rebuilding cities. The president would also follow the Reuther plan for Demonstration Cities, “and rebuild completely, on a scale never before attempted, entire central and slum areas.” Working together with private enterprise—this time, Johnson did not emphasize municipal governments—the federal government would rebuild areas of up to 100,000 people. Johnson would add shops, parks, and hospitals around the new housing. In the same speech, the president asked Congress to pass legislation funding rent assistance. Taken together, the results, the president hoped, would be something similar to what his old community action drive had sought: “a flourishing community where our people can come to live the good life.” This whole second project would resemble something like what the United States had done in rebuilding Europe under the Marshall Plan. Eager to make Detroit the star of the new campaign, Reuther rounded up support in Michigan. Reuther wrote to Mayor Cavanagh to encourage him: “Detroit can become an exciting and shining model of a 20th century city in the Great Society.” Reuther promised Cavanagh that they could work together in a new institution, the Detroit Citizens Development Authority.

Without the gold standard, a democracy will always vote itself into insolvency or hyperinflation, according to Alan Greenspan, 1960s version:

Greenspan wrote that American overspending wasn’t strength or a wartime phenomenon; it was predictable. A welfare state, which was what the United States had become, always overcommitted. “The welfare statists,” Greenspan said, were always “quick to recognize that if they wished to retain power, the amount of taxation had to be limited and they had to resort to programs of massive deficit spending, i.e. they had to borrow money, by issuing government bonds. . . . Gold stands in the way of this insidious process. It stands as a protector of property rights. If one grasps this, one has no difficulty in understanding the statists’ antagonism toward the gold standard.”

Not every Black American meekly agrees with white saviors:

On January 18, 1968, the day after the State of the Union, Mrs. Johnson received a reminder that many Americans could not agree. The First Lady hosted a “Women Do-ers” lunch at the White House, with fifty guests. Among them was the black star Eartha Kitt, whom Americans knew as an actress, singer, activist, and star on Batman, where Kitt played Catwoman. Johnson himself entered mid-lunch to address the group. The president spoke about expanding Social Security. Kitt spoke up, too, speaking not about entitlements, but noting that “because taxes are so heavy, both parents have to work.” Johnson was taken aback, and announced he had just seen through the passage of a Social Security bill that allotted millions for day care. A “non sequitur” was how Kitt characterized Johnson’s reply. Kitt so intimidated the president that he fled the room, saying such questions were “something for women to discuss here.”

When Nixon takes over, the machinery put in place by Johnson hums at an accelerated pace.

Despite the historically low unemployment rate, federal welfare payments were exploding. In one of the first of a number of long, careful memos that Moynihan penned to his future boss, he offered New York City as an example. New York’s welfare payments alone amounted to $ 2 billion, double the once huge-sounding initial budget for the War on Poverty. Nationally, spending for the old welfare system had risen by half in just two years, and spending for the disabled was up by 26 percent in the same period.

The Democrats have to top whatever the Republicans promise:

Rather than going along with Nixon, McGovern, perhaps already thinking of the presidential race in 1972, was readying his own plan, payments of $ 600 per child for all families below the middle class, a program that would cost multiples of the Nixon scheme. Hubert Humphrey, momentarily shocked, noted that the McGovern plan would place close to half of the United States on welfare. A new lobby, social workers, also made its objections known. President Kennedy’s and Moynihan’s Executive Order 10988 long ago had transformed once weak public-sector unions into titans. The American Federation of State, County and Municipal Employees, one of those newly powerful unions, counted thirty thousand social workers among its members. Now social workers rose up in blunt defense: “This legislation threatens to eliminate the jobs of our people,” said the union spokesman.

The book describes the importance of Goldberg v. Kelly, a case that turned handouts into “entitlements” akin to a property right.

How about three weeks to flatten the curve turning into 16 months of restrictions? Is that new?

Pete Peterson had supported the temporary income tax, but when, later, Connally and Nixon advocated keeping the tax in place through the 1972 election year, Peterson was, by his own description, “aghast.” Doubly infuriating was that Nixon broke a promise, by making something he’d labeled “temporary” seemingly permanent. Herb Stein, the most reflective in the group, wrote several essays about Camp David. “Even now, I am amazed to think of how little we looked ahead during that exciting weekend at Camp David when we (the president, really) made those big decisions,” he wrote in 1996. “We were going to freeze wages and prices for ninety days. What would happen after the ninety days? I don’t remember any discussion of that.” As it turned out, Stein noted, some of the freezes lasted more like a thousand days.

As with a lot of history books, this work is interesting for showing the reader how little has changed. Americans still have the same issues, e.g., some people don’t want to work at all and others have a level of skill that is not high enough to command what we would call a “living wage.” The arguments on all sides are more or less the same as today (remember that universal basic income was tried in 1970; see Long-term effects of short-term free cash (guaranteed minimum income experiments)).

Probably the biggest change from the 1960s is immigration. The architects of our welfare state imagined that the U.S. had a fixed supply of uneducated badly housed poor people. The $billions in tax dollars would lift each of those people out of poverty via education and job training, fresh public housing, new infrastructure, etc. After that had been accomplished, there wouldn’t be any more poor people. It didn’t occur to them that 1 million low-skill people, destined to be poor in an economy for which they lacked the job and language skills, would walk across the border each year. Certainly they didn’t imagine that their creation of the welfare state itself would attract low-skill migrants, for whom the welfare state removes all risk of migration (if employers don’t want a migrant or the migrant does not enjoy working, public housing, health care, food stamps, etc. are all there as an alternative to work).
