Re: Control electronics
That’s a good point about IAS, Lee. Fortunately I think it would be possible to apply a transfer function in the microcontroller to estimate the actual airspeed in a straightforward way, by encoding a hopefully accurate model atmosphere.
So really, with a Pitot tube, we can gain three measurements: static pressure, IAS and corrected actual airspeed. Combined with accelerometer and GPS data, one could build a nice system that uses primarily inertial guidance up high, GPS at moderate altitudes supplemented with barometric altimetry when the air thickens (as indicated by static pressure). The saved data could make for some interesting analysis after the fact as well.
I have been thinking about Lester’s comments about the engine; I think I may know what their engine idea is — if I am right, it will be brilliant.
