Abstract:

For implementing the Strength and Stiffness Spoecification of Military Aircraft of China, a set of analysis and calculation methods for aircraft flight loads is presented, which uses nonlinear aerodynamic data of wind tunnel test. Based on the specification, a set of software with flight loads database for nonlinear flight loads analysis is developed successfully. The software has been used for flight loads calculation of F×× aircraft.

Key words: aerodynamic load, inertial load, flight envelope, load envelope
