Research on Bird Strike Airworthiness Certification Technology of Civil Transport Helicopter
As a low altitude space aircraft,helicopter has a high probability of bird strike.Mean-while,with the increase of flight speed,the harm of bird strike accidents for helicopter is also gradu-ally increasing.The harm of bird strike to the safety of civil helicopter cannot be ignored.Based on the requirements of bird strike in the CCAR-29 regulations and the characteristics of transport heli-copters,the bird strike clause was researched,the road-map of compliance verification was sum-marized and sorted out and the work was clarified that needed to be carried out in bird strike compli-ance in this paper.In addition,combined with the verification of the bird strike of one type civil helicopter,the concerned factors in the certification process were discussed,which provided some i-deas and references for the helicopter bird strike compliance review,so as to meet the needs of heli-copter development and certification.
