Theoretical calculation method for optimum amount of bonding agent in composite solid propellant

The invention provides a theoretical calculation method for optimum amount of a bonding agent in a composite solid propellant. According to the method, the surface area of solid filler in the propellant and structural characteristic parameters of the bonding agent are calculated to obtain a theoretical calculation result of the optimum amount of the bonding agent. The method has the advantages that the calculation result can be used for guiding propellant test work to avoid blind test and reduce the workload of the test, so that the costs of manpower and material resources are reduced and theproblems that the test time is long, the test amount is large and a lot of manpower and material resources are consumed in the prior art are solved. 本发明提供了种复合固体推进剂中键合剂最佳用量的理论计算方法，通过计算推进剂中固体填料的表面积以及键合剂的结构特征参数，获得键合剂最佳用量的理论计算结果。该计算结果，可用于指导推进剂试验工作，避免盲目试验，减少试验的工作量，减少人力和物力成本，解决了现有技术中试验耗时长，试验量大，耗费大量人力和物力的问题。
