火箭助推发射飞机模型设计方法研究

火箭助推发射是无人机起飞的一种形式．模型飞机火箭助推发射试验是采用自由飞模型试验的形式，按运动相似条件进行的．模型飞机应符合几何相似、质量相似、运动相拟和动力相似等条件．本文以＂长空＂无人机的１．５模型为例，介绍了无人机模型设计参数的选择以及有关的设计计算和调试方法．以三种火箭助推发射形式进行的试验结果证明，飞机模型的设计方法是可靠的，对于进一步研究火箭助推发射无人机具有参考价值．

A Study of Design Methods of Rocket Projected Model Aircraft

Rocket projection is one of the methods for launching pilotless aircraft.The free flight model test is selected in the launching test of rocket projected model aircraft according to the simulant conditions of motion,which demands that the model aircraft have the similarities in geometry, mass, motion and dynamics.The CK1-M model aircraft with a scale of 1:5 is taken as an example. This paper introduces the transformation of similarity between a model aircraft and a full-dimensional one,the selection or design parameters of the model aircraft,and the relevant design calculation and test methods. The results from three kinds of rocket projection test show that these design methods are reliable and valuable for further researches on rocket projected pilotless aircraft.
