چکیده انگلیسی
A general mathematical model of carrier based aircraft ski jump take-off is derived based on tensor. The carrier, the aircraft body and the movable parts of the landing gears are treated as independent entities. These entities are assembled into a multi-rigid-body system with flexible links. Dynamical equations of each entity are derived on the basis of the Newton law and the Euler transformation. Using the invariance property of the tensor, the dynamical and kinematical equations are converted to tensor forms which are invariant under time dependent coordinate transformations. Then the tensor formed equations are expressed by the matrix operation. Differential equation group of the matrix form is formur lated for the programming. The closure of the model is discussed, and the simulation results are given.
