Abstract:

In the paper,the spin behavior of the JJ6 aircraft is analysed and predicted by the bifurcation analysis and catastrophe theory, meanwhile the computation of time history is carried out.The mechanism of spin motion and the function of various control surfaces are explored during the aircraft entry into and recovery from, a spin. The theoretical computation results agree with the flight test results in most of the situations.

Key words: high angle-of-attack, spin
