Abstract

Recent Federal Aviation Administration (FAA) promotion of Angle of Attack (AOA) systems for stall prevention to reduce Loss of Control In-flight (LoC-I) accidents in the General Aviation sector has resulted in a proliferation of affordable AOA systems. Most systems consist of a multi-hole differential pressure sensor or a rotating vane sensor for estimation of AOA, some also require additional data from an Air Data Computer. This paper examines an alternative method for multi-point AOA sensing using COTS MEMS pressure transducers. The method employed multiple chord-wise sensors to measure local pressure and this was used to estimate local AOA for improved stall awareness. The results suggest that the multi-point method is feasible for AOA sensing and can provide local stall warning relative to a local chord airfoil. Expanding the system to span-wise has the potential to improve total stall awareness.
