| Abstract: | This paper introduces a new method to solve the singularity of Euler equation.First,the detailed calculation equations are attained from the movement equations of aircraft.Then some numeric calculation validation are simulated with the six degrees of freedom simulation.The third,through a lot of analysis and engineering calculation there are no the bug of principle and method error,the results show that singularity is disappear.The method is applicable and reference value for flight simulations and attitude controls. |
