Research on Technologies for the Flight Test of Civil Aircraft Stall Protection Control Law

Aiming at the flight test for stall protection control law of civil aircraft, its main functions were summarized based on the analysis of the typical structure of control law. And the purposes were provided for the flight test of the stall protection control law. The flight test was divided into two stages. The details of the contents, operations and evaluations for flight test were studied. The test risks were analyzed and could be reduced by the measures provided. And the key strategies for adjusting parameters of the stall protection control law were provided and the engineering recommendations were made too. The technologies for the stall protection control law were verified effectively by the methods of simulation and flight test. This study provides useful reference for the design, development, and flight test of the stall protection control law for civil aircraft in China.
