The reynolds number for the combined prop pitch and prop airfoil (and resulting torque) which is the PRIMARY determinant of shaft horsepower to final thrust is well understood at these altitudes. 3.) The ONLY issue with diesel is can he get enough oxygen to it to keep it lighting off efficiently. With the turbo I thinking that will be a resounding yes. That science was also solved back in the 40's as well. (i.e. The Mustang Merlin/Supercharger combo) [youtube]http://youtu.be/Rh-ClOSuoEc[/youtube] [youtube]http://youtu.be/lzdu4RtRt2E[/youtube]

The goal for this aircraft was performance AND affordability. If Peter spends $20 million on this project, no matter how it performs. It’s not going to be a $150k aircraft. It’s the whole point using the Audi engine. To make a high performance, affordable aircraft.
As far as who cares how much money he spends. No one would if it was his money. That last $2.7 million was from people dropping $20,000 to move to the front of the line.
The escrow milestone is vague. He’s going to fly it around the patch, talk about how he can work on the mapping of the engine and ask for the escrows to be released. And when a 200 hp SR20 outruns it down the runway, I don’t see it performing anywhere close to his claims.

I think it’s up around 3100 lbs and he hasn’t put the backseats in it.

You say this to anyone who has a deposit on the raptor and they have no response. If you could move 3000 pounds at 300 knots on 300 HP for less than 300k.... the economy would force GM and Ford to start mass producing them. Flying cars would be happening already. But PHYSICS.

Well, if you are selling people tickets to the Moon and you miss, it may be preferable for them to die in space than return safe but angry, looking for a refund. (Perhaps that should have been green)
That’s another piece the cheerleaders are missing. You have someone taking other people’s money on promises he can’t keep and is quite frankly not even competent enough to have made. Is this not an ethical problem as long as he is shooting for the moon and in the ring? My dictionary still calls that fraud.

It’s been dozens of pages since I mentioned it, so here it is again: Jim Bede. Most of the Raptor fanboys are probably too young to remember the BD-10, -12, and -14. The story on the 12 and 14 is pretty similar to the Raptor. They got fatter and slower until the first test flight, which achieved an altitude of less than 10 feet IIRC, ending in a non-fatal crash, after which the project was shelved. Test pilots of the -10 had the misfortune of actual flight, which resulted in a fatal accident. To be fair, Bede sold the -10 before the fatal, but after multiple incidents. I’d love to see an airplane with the Raptor’s projected specs and price, but it’s just not possible to get faster than MU-2 speeds at Skyhawk fuel burns and a kit price lower than an RV-10.

Brave/humble of you to admit that. :-) Nice job.
Was meant more along the lines of a forgone conclusion to a first round $200 Jeopardy question.

So sorry to be the pedantic one, but are you sure about that distance to the nearest star? I'm happy to admit I may not be familiar with the units you are using there, but to me, the nearest star is only 150 million kilometers away, so that's about 93 million miles...
