I'm having a go at making an angle of attack display using a differential pressure module and an Arduino Uno.
The module senses up to 7Kpa max per port (about 1psi unless I've gone seriously wrong- very possible)
The hardware bit is easy but I'm not yet up to speed on coding for prototyping.
My questions are ; has anyone already written the C++ code for a similar sketch? It's proving to be a steep learning curve and I'm lazily happy to use someone else's work
Also has anyone measured/ know what sort of psi a pitot pressure port experiences at about 100 knots?
Supplementary question; is the pressure so found proportional to the cross section area of said port/ tube?
I have a feeIng I read once that pitot tubes can be any size, but that this is often disputed.
If anyone is interested, I found some interesting NASA research on making an Alpha and yaw measuring pitot tube array for their lifting body research program (ages ago now) - no moving parts and very easy to fabricate. Ideal for the microprocessors and modules available now, but undreamed of then.
Fingers crossed
