Abstract

Abstract

With the development of undersea vehicle technology, higher design requirements of small volume, light weight, low disturbance and low noise have been put forward for its ejection and separation device. In this paper, a systematic study is carried out on the key technologies of the piston-type ejection pyrotechnic nozzle device. The working principle of the device and the operational process of projectile ejection are clarified through principle analysis. Based on the zero-dimensional internal ballistic model, the pressure-time characteristics of the combustion chamber are numerically simulated and calculated. The two-dimensional steady-state numerical simulation of the Laval nozzle flow field is conducted by using FLUENT software, and the design scheme is verified through land-based and underwater ejection tests. The research results show that the design scheme adopting the convergent-divergent Laval nozzle can significantly improve the energy conversion efficiency, effectively reduce the device volume and the propellant charge amount, thus enhancing the system safety. By innovatively applying the Laval nozzle to the piston-type ejection pyrotechnic device, the key problems of large energy loss, large system volume and insufficient safety in the traditional underwater ejection technology are successfully solved, which provides theoretical basis and technical reference for the optimal design and multi-platform application of underwater ejection devices.
