激光燃速仪用于推进剂非稳态燃速测量

Measurement of Nonsteady Burning Rate of Solid Propellant Using Laster Strand-Burner

简要介绍了无跟踪装置激光燃速仪的基本原理，它可以分辨燃面１０μｍ的变化，其最大相对误差小于±０．５％，采用这种仪器对于固体推进剂压强振荡过程的非稳态燃速进行了测量。

This paper presents the basic principle of a new laser strand-burner without tracking unit which can resolves a change of burning area of 10μm with a relative error less than ±0.5%. The measurement of nonsteady burning rate of a solid propellant under pressure oscillation was carried out using the instrument.
