WARNING: semi-hijack.
Sam, you started a thread several years ago on this subject. I wanted to join in, but I had an old computer with a dial-up connection (over Mexican phone lines) so I didn’t. I think you’re wrong in almost everything you say about airplanes, and here’s why:
First, the reason that airplane engines were designed in the thirties is because, in fact, no one has ever come up with a better design. Besides, it’s rather like saying that Mercedes Benz engines are based on a 1917 design because Peugeots had double overhead cams and hemispherical combustion chambers. There are basically no parts from a modern engine that fit an engine from the thirties; electronics, fuel systems, quality of materials, etc. are infinitely better than they used to be. But a horizontaly opposed, air cooled engine like a Lycoming or Teledyne seems to be the most efficient way to go. Teledyne spent tens of millions of dollars on their Tiara designs, which had all the bells and whistles- geared, overhead cam, liquid cooled, and so forth, and gave up in the end because the Tiara was heavier, a little less reliable, and more expensive than the old aircooled, pushrod designs you scorn. So they stopped making them.
Some years ago I was at OshKosh for the fly-in, and I had a long conversation with some engineers from Bombardier (They make everything from Lear Jets to snowmobiles) who were showing their new 250-400 horsepower V12s, like the Tiara geared, liquid cooled, integrated electronics and so on. They told me that:
The paperwork to get the engine FAA approved came to about ten percent of the development cost, and that they would have done most of the testing required anyway: and:
They weren’t sure their new engine would out perform a Lycoming 540.
They never produced the V12, as far as I know.
Most of the new engine designs, especially diesels, are coming from Europe- Germany, France and Czechoslovakia mostly, and they have much more intrusive government controls over aviation than the USA does.
As for the Vari-Eze, it’s a great plane, but the reason it costs $10000 is because you have to invest the time to gain the skills necessary to build it, and then the 1000 or 1500 hours to put it together. Which brings the price right up to the Cessna’s, unless you think you can run an aircraft factory for less than $150/hour/employee. And besides, Burt Rutan stopped selling the plans many years ago, and won’t even talk about it today, for the same reason that a Cessna 172 costs what it does: insurance against lawsuits.
Which is why the Cessna is the same airplane, more or less, that it was thirty years ago: any modernization, re-engineering, or any other upgrade will be immediately seized upon by lawyers to sue the manufacturer because the lawyer’s clients’s thirty-year-old airplane didn’t have it. Some years back somebody launched a multi-million dollar lawsuit against Piper because their 1947 Cub didn’t have safety harnesses factory installed, which no light planes had at the time; I think there was a thread about the suit here. And since lawsuits seem to be the basis of the Libertopian legal system, I see no reason to think that the suppression of innovation problem would be any less.
