直升机无障碍机场A类性能起飞决断点试飞研究

Research on helicopter CAT - A performance take-off decision point on clear runway

摘要:

A 类性能是运输类直升机的典型特征，A 类性能飞行试验是表明符合性的最佳途径。以CAAC 颁布的相关A 类性能适航文件为基础，分析A 类起飞性能产生的背景，研究相关规章条款的要求和符合性方法，探讨极限高度—速度包线、A 类起飞航迹、A 类继续起飞和中断起飞以及最终起飞决断点确认等试飞技术，制定无障碍机场A 类性能起飞决断点试飞风险管控措施。构建的直升机无障碍机场A 类性能起飞决断点试飞方法及试飞风险管控措施，有效地指导完成了AC312E、AC313 等直升机的局方审定飞行试验工作，为其获得CAAC 型号合格证奠定了基础。

Abstract:

For a civil transport helicopter, the acquisition of type certificate shall follow requirements specified in CCAR29, among which CAT-A performance is a typical feature of transport helicopter, meanwhile CAT-A performance flight test is the best way to verify its conformity. Based on the relative CAT-A performance airworthiness documents issued by CAAC, this paper analyses the background of CAT-A take-off performance, researches relative clause requirements and compliance method, discusses flight test techniques concerning H-V domain、CAT-A take-off flight path、CAT-A continued take-off、rejected take-off、 and the determination of final take-off decision point, making CAT-A performance take-off decision point flight test risk management and control measures for clear runway. The CAT-A performance take-off decision point flight test method specified in this paper has effectively instructed the CAAC certification flight test toward AC312E, AC313, laying a sound foundation for the fore said helicopters to acquire CAAC type certificates. Research of this paper could provide referential value to CAAC test pilots as well as reference to applicant test pilot.
