In addition to sensors such as load cells, prandtl tubes, pitot tubes, which other sensors are put on experimental aircraft
Hi,
I think that an AOA sensors (Angle Of Attack), allways an IMU is very usefull, Maybe a GPS, radio altimeter.
It's a tripulated aircraft?
Best regards!
Passive vs. active sensors -- Passive sensors measure light reflected or emitted naturally from surfaces and objects. Such instruments merely observe, and depend primarily on solar energy as the ultimate radiation source illuminating surfaces and objects. Active sensors (such as radar and lidar systems) first emit energy (supplied by their own energy source) and then measure the return of that energy after it has interacted with a surface. Use of data collected by passive sensors often requires accurate measurements of solar radiation reaching the surface at the time the observations were made. This information allows for the correction of "atmospheric effects" and results in data or images that are more representative of actual surface characteristics.
Do you mean Experimental according to FAA rules, for which you can design or/and manufacture your aircraft? If so, I can be helpful to you. Years ago I have manufactured the Long-Ez, designed by Burt Rutan, and I have obtained the permit to fly it by the aviation authority. For the sensors that are needed, this depends from what you want to control during flight. If you do have a well experimented motor, some sensor to control the temperature of oil, the head temperature, the RPM, the manifold pressure, the Volts and the Amperes of the electric alternator, and this is just for the engine. Obviously a GPS sensor and a AHRS (Attitude and Heading Reference System) to be connected to a digital display into the cockpit. These AHRS are nowadays very reliable and accurate plus, good to know, not so expensive. You can go on the internet to find a lot of them. If you think that radios are also sensors, of course you will need uhf radion for the communications with ground and other aircraft. Strain gauges are required only if you are not sure of your design and quality of construction, also for thes items there is a lot of choice, together with the data loggers. I suggest the DATATAKER series 80, that can record stain gauges, thermocouples and pressure via presure transducers.
There is only to know what you want to obtain. Good luck!
