摘要:
火箭导弹燃气射流对发射装置的冲击载荷是发射系统结构和刚强度设计的重要依据。为了获得这一冲击载荷,该文针对燃气射流对发射装置迎气面的冲击特征,建立了火箭导弹燃气射流压强测量系统,并采用该系统对某火箭燃气射流冲击载荷进行测量。根据箱式结构迎气面特点进行测量前盖测点布设,测得某火箭弹的燃气射流压强-时间曲线。结果表明,药温60 ℃、射角30°时,各测点的压强峰值均小于0.15 MPa,且均随火箭弹逐渐远离测点而衰减,冲击时长约为400 ms。其中发射管中心测点受到的冲击压强最大,距发射管中心越远的测点受到的压强越小,且峰值时刻滞后; 不同药温和射角时迎气面冲击压强的分布具有相似性。编程处理压强-时间曲线,得到不同发射状态下的压强-半径测量结果。通过对压强-半径进行迎气面面积分,得到了各发射状态下的燃气射流冲击载荷。该文方法还适于集束式定向器迎气面的压强测量。
Abstract:
The impact load of jet flow on rocket and missile launchers is the fundamental design basis for structure and rigidity of the launching system. Through analyzing the impact characteristics of jet flow against the flow-facing surface of the launching system,a measurement system of jet flow pressure based on the strain sensor is established in this paper. The measuring points are arranged on the front measuring cover of the lauching box according to the characteristics of the flow-facing surface of the box structure,and the pressure-time curves of the rocket is obtained experimentally. The experimental results show that the pressure peaks at each measuring point are all less than 0.15 MPa when the charge temperature is 60 ℃ and the firing angle is 30°,and they all decrease with the rocket moving away from the measuring points. The impact duration is about 400 ms. The measuring point in the center of the launch tube is subjected to the greatest impact pressure,and the further away from the center of the launch tube,the lower the pressure and the later the peak time. The pressure-time curves on the flow-facing surface are similar under different powder temperatures and launch angles. By programming the pressure-time curves,the pressure-radius measurement results under different launch states are obtained. The impact loads of jet flow under differemt launch states are calculated by integrating the pressure-radius into the flow field. The measurement system in this paper is also suitable for the pressure measurement of the flow-facing surface of cluster-type tubes.
