The key technology of aircraft surface flow field test based on high precision pressure sensing

Aiming at the limitations of numerical methods and experimental techniques in the testing of aircraft surface flow field, this paper proposes an aircraft surface flow field method based on high precision pressure sensing, designs a high precision surface pressure sensor with double pressure sensitive membrane and resonator, and carries out agile intelligent pressure sensor system integration. To realize the aircraft surface flow field reconstruction of steady-state RANS numerical calculation and non-steady-state RANS numerical calculation, and effectively obtain accurate all-domain and all- physical aircraft flow field information.
