Abstract:
After the feasibility theoretical analysis of the new ejection system improvement of a certain existing service type,a mathematical physical model of combined nitrogen ejection system with the driving energy of nitrogen is established.By using gas dynamics theory,the movement process for high-pressure nitrogen driving the piston to propel the suspender until it is completely away from the nitrogen-ejection hook is simulated and analyzed.The influence laws of the four structural parameters of the ejection system on the ejection performances are simulated and analyzed.The simulation and calculation results show:the device can reach the index requirements of the object design.It can also set the structure and physical parameters of the ejection system reasonably to make the maximum acceleration and maximum speed reach the index requirements of the object design when the suspender is ejecting away from the airplane.
