中文摘要:在描述风车起动和起动机起动过程的基础上,对比分析了起动机起动和风车起动的起动时间和点火时间。通过研究可知:(1)风车起动和起动机起动时间对比主要取决于起动机脱开前阶段,由于起动机的带转作用,起动机起动时间较短,但随着飞行速度增大,起动时间逐渐和风车起动接近;(2)风车起动和起动机起动的点火时间对比,主要取决于点火准备时间,起动机起动点火时间相对较长,随着飞行速度的增加,逐渐和风车起动点火时间接近。该研究可为发动机起动系统设计以及发动机空中起动试飞数据分析、排故提供参考。
英文摘要:Based on the description of windmilling start and Starter start,the Start time and Ignition time between them were compared and analyzed in this paper. By researching, we know: 1) The differences between windmilling start time and Starter start time mainly depend on the step before releasing starter. Because of the high acceleration of Starter, engine can be started in a shorter time. As the flight speed increases, the effect of Starter start decreases. The starter start time gradually approaches the windmilling start time. 2) The difference between their Ignition time mainly depends on preparation period of ignition. The starter requires longer ignition time. With the increasing of flight speed, the Starter Ignition time gradually approaches the windmilling ignition time.This study can provide reference for engine start system design and engine airstart flight test data analysis and troubleshooting.
