针对传统的效能系数计算方法存在的无法准确预示飞行状态整流罩分离运动的不足，以典型的旋抛整流罩为研究对象，提出了一种将全部因素作为计算变量的多因素计算方法，建立了整流罩分离动力学方程，论述了每个变量的获取方法，在地面大气环境中采用某型号真实整流罩，开展了分离试验，获取了罩内负压特性和分离运动参数，计算结果与试验结果一致性较好。相对于传统的效能系数计算方法，多因素计算方法更加准确，对指导整流罩分离系统方案设计更加有效，具有显著的工程应用价值。%The traditional energy coefficient calculation method cannot forecast the faring separation accurately. Taken the typical rotation casting faring as the example, a new multi⁃factor calculation method was proposed which set every factor as the variable. The faring separation dynamic equation was established and the method to compute each factor was discussed. Then the ground separation test was carried out with a real rotation casting faring. The negative pressure characteristics and the separation motion parameters were obtained which demonstrated that the calculation result was con⁃sistent with the test result. Comparing with the traditional energy coefficient calculation method, the multi⁃factor calculation method is more accurate and more efficient to guide the faring separation sys⁃tem scheme design. It which has prominent engineering application value.
