Suspension Means Suspension Submunitions Development And Test Of Endurance

On the modern battlefield in which the powerful anti-ship weapons become stronger, radar scans have blind spots and short protection system has defects, a new concept of passive low-altitude defensive weapons-bombs called suspension ammunition had been raised. It can suspend for a specific short-term endurance in a certain position of combat by using its own power source driving lift device to achieve air defense. The suspension ammunition arrays are arranged on the routes of incoming enemy aircraft or missiles to build the last defense line for ships or protege by damaging or leading the enemy missile to deviate.The key technology of suspending ammunition is air suspension device which includes two parts:lift and drive modules. After the study of the lift and drag characteristics of lift module, the paper mainly had done the research about driving performance of the suspending driver module while staying in the air. The combination of theoretical calculations and experimental validation had been used in order to study multiple jet tube suspension device.After the analysis and calculation of the air suspension driving module using the blade element theory, the theory of slipstream, the requirements of the performance of the corresponding suspension of driving driver module had been presented. According to the basic equations of fluid motion, Reynolds transport theorem, the continuity equation, modeling and analysis of the multiple jet tube suspension device drive module driving force had been done in which modeling and analysis of the entrance flow and driving performance are involved. And by testing the prototype of different factors that effect driving performance, the driving performance had been achieved. Comprehensive test results show that:the driving performance of multiple jet tube suspension device can meet the requirements of suspending bombs and the device can suspend in the air for a while.This paper studied the characteristics of lift and drag suspension lift module, with the analysis of theoretical modeling and experimental study of multiple jet tube suspension device, and get the best program after comparison of different designs. At the same time, researches about air volume and pressure of high gas pressure chamber had been done. This paper will lay the foundation for the design of interior components and high gas pressure chamber and is valuable for relative research.
