| Catapult take-off as the mainstream of the current carrier-based aircraft take-off technology, with its outstanding advantages and broad application prospects, has been applied in succession of States Navy. At present, all our theoretical and experimental in technological research of catapult take off is not mature. Therefore, there is important theoretical significance and practical value in engineering in the analysis of the dynamic response of carrier-based aircraft catapult take-off and in-depth study. The main content of this paper is as follows:First, the process of carrier-based aircraft take-off is briefly described in this paper, and the processes with its characteristics of catapult and ski-jump take off are analyzed respectively. The way of using ramp deck in catapult take-off is proposed in this paper. And then, the enforceability of this way is qualitatively analyzed. Secondly, the process of Catapult take-off is simplified reasonably. Accordingly, the mathematical model of take-off process at different stages of the aircraft is established, while the practical engineering calculation methods of describing the shape of ramp deck and the dynamic equations of take-off process for each phase is given.Then in this paper the method of building airframe subsystem, front landing gear subsystem, rear landing gear subsystem, front landing gear tire subsystem and rear landing gear tire subsystem and three-dimensional runway is studied. Based on a certain type carrier-based aircraft, aircraft model is built. At last the process of ski-jump takeoff is simulated. The effects of Ejection force, angle of attack, and aircraft mass, are discussed quantitatively. Analysis showed that the use of Ramp deck can make the carrier-based aircraft catapult take-off have a better take-off performance, an Easier way to meet the requirements of safely take-off. The results provide theoretical basis and simulation analysis of data for the way of catapult/ Ramp deck take off of carrier-based aircraft.
