| Abstract: | Firstly,the departure characteristic and spin sensitivity were analyzed by some criteria for a certain advanced trainer.Then,the mathematic model of spin was given in the form of vectors.And then,two decomposing methods of motion were analyzed and the aerodynamic coefficient was built up respectively.Finally,a numerical example was given for predicting the departure and spin characteristic for a certain advanced trainer.The simulation results demonstrated that Kalviste decomposing method,combining with high... |
