Ramjets are most efficient around Mach 3 and run out of steam due to heating of the intake air from compression around Mach 6.4. In order to go...
This certainly has almost nothing to do with the Raptor, but let's assume materials capable of dealing with arbitrarily large temperatures - say...
What's your definition of "on-schedule"? Have they published one in the last 5 years? A search of the FAA registry turns up about 96 US...
The prototype ICON A5 was a flying testbed for zillions of ideas, and it flew hundreds of hours and was modified countless times It started flying...
You're right - it is. But the statement I was responding to was the one where you said this: "...We aren't going to solve the equation for the...
A 14 second search on google for "calculate airplane neutral point" turns up a stack of articles on doing exactly that - closed form neutral point...
Certainly there are some epoxies that are susceptible to ethanol, which is why I explicitly said "...the right epoxy". There are many folks using...
Thousands of EZ type aircraft with 40 years of experience with only epoxy on the inside of the fuel tanks would beg to differ. You have to choose...
Since a Long-EZ has an L/D of about 15:1, and a COZY MKIV has an L/D of about 12 - 13:1, and a Velocity is about the same or a bit lower, even...
I obviously don't spend a great deal of time and effort defending Peter's design skills, but I'll throw this in for consideration. When the first...
Yeah, but because it was done in public, just look at how much entertainment value it gave us here for the last 4 - 5 years. That's worth $2.7M,...
There are certainly autodidacts among us, who can learn and become experts in something without going to school for it for many years. But they're...
So I'd like to apologize and say that obviously, I was wrong. My interpretation of the rules clearly doesn't line up with at least one DAR's...
It was more that the much larger moment coefficient when the flaps were extended caused the canard to run out of authority without moving them...
We're talking about the AC of the aircraft as a whole, not of the canard alone. As the canard area gets larger with elevator deflection, that...
Separate names with a comma.
