Research On Simulation Software Development Of The Ejection Seats

The developing adaptive technology is the core technology of the4th generation ejection seats.The key technology is thrust-vector and flight control. It is practical significance to researchperformance simulation software development of our country’s ejection seat, and analyzes the ejectionhazard degree according to the above, which can largely improve the range of ejection lifesaving andoffer the Simulation data and processes to attitude-control device.Firstly, by analyzing the movement of a certain type of the ejection seat, the corresponding sixdegree of freedom equations-of-motion is set up, and take based on MATLAB/Simulink platform s ascomputing core, was trying to develop on the VC++/MFC platform seat ejection performancesimulation software with friendly user interface.Secondly, take software’s simulated data as afoundation,Has analysis of the disadvantageous posture under the reliability of our country’s ejectionseat.Finally, Based on the altitude of the ejection height, aircraft sinking rate and seat/occupantsystem’s attitude and other parameters.,carries on the appraisal to pilot ejection’s life-threateningdegree,establishing the lifesaving time computational method,and used this as security ejection scopetarget function.Meanwhile under unfavourable attitude has conducted a preliminary analysis of theemergency life-saving.This work can be instructional to the further research of the self-adaptionejection seats.
