摘要
本文采用一种新型设计思路进行火箭橇设计,将助推用火箭发动机壳体设计为火箭橇主梁结构,并利用简单整流结构将火箭发动机壳体与火箭橇试验滑靴联结组成火箭橇试验橇体,大幅度降低了火箭橇体质量,减小了火箭橇滑行过程中的空气阻力,有效地提高了火箭橇推重比.此方法研究的火箭橇可以作为高Ma数火箭橇试验平台进行重复使用.
This paper provides a new method for rocket and sled design, with the boosting rocket engine shell designed to be the main girder of rocket sled, and the boosting rocket engine shell and the slippery boots combined to form rocket sled testing structure. Using this method can reduce the mass of rocket sled and the aerodynamic drag in gliding, and increase the thrust-weight ratio effectively. This type of rocket sled can be reused as a testing platform for a high Mach number test.
