固体火箭发动机燃速相关性研究

RELATIVITY OF THE BURNING RATE IN SOLID ROCKET MOTORS

本文通过Ф118mm标准试验发动机与某型号固体发动机燃速相关性的试验研究结果证明:推进剂药条燃速与Ф118mm标准试验发动机或与型号固体发动机的燃速在其各公差范围内,不存在相关性;只有Ф118mm标准试验发动机与型号固体发动机燃速间具有强相关性.本文通过回归分析给出了燃速的回归方程数学表达式.本文在国内战术型号固体发动机批生产中是首次提出并得到实际应用.

The test on relativity of the burning rate in φ-118mm standard motor and in certain solid motor is conducted. It is demonstrated, that among the burning rates of the propellant grain sample, the φ-118mm standard mptor and the certain solid motor no relativity exists in their respective tolerances. Strong relativity is found only between the burning rates in the φ-118mm standard motor and the certain solid motor. A mathematical regressive equation on burning rates is presented in this paper, which is first mentioned and applied in commercial production of tactical solid motors in our country.
