Measurement of aerobatic flight characteristics

conference paper

English

Determination of flight parameters in non-steady turns (e.g. aerobatic manoeuvres, stalls, spins) is one of the most complicated tasks within the flight measurement, from the point of view of character of performance and aircraft equipment. Limitary parameters of flight for components of aerobatic manoeuvres are integral part of technical documentation of corresponding aircraft category. According to the Airworthiness standards, aerobatic and training aircraft classes have to have the ability to do safe aerobatic turns that requires type certificate. There are measurements, done within the flight measurements at the Institute of Aerospace Engineering in Brno, which made possible to monitor the whole aerobatic configuration of the two-seat, all-metal sailplane L-13 AC Blaník. During the test flights, the basic aerobatic elements, such as loop, stall turn, inverted flight, roll, etc., were done with the sailplane. It was necessary to equip the aircraft with the measurement technology capable of scanning large number of flight quantities for example attitude angles, angel of attack, sideslip angle, airspeed and flight altitude, etc. The part of this paper is the description of preparation (setup, installation, verification and activation of the measuring system), measurement performance and results processing.
