Research on Comparative Monitoring Method of Aerodynamic Coefficient Applied to Artificial Ice Flight Test

Abstract

Abstract In the implementation of the artificial ice flight test, artificial ice shapes must be installed to the test aircraft, which reduces the aerodynamic performance of the aircraft and leads to a high risk. In order to reduce the risk of artificial ice flight test, starting from the flight test requirements, this paper proposes a real-time comparative monitoring scheme of the design lift coefficient and the actual lift coefficient of the test aircraft, and develops a comparison model of aerodynamic coefficients accordingly. Verified by the flight test data, the model can figure out reasonable design lift coefficient and actual lift coefficient, which lays a foundation for the subsequent application in the artificial ice flight test.
