中文摘要:
      民用飞机的噪声适航审定需要多次重复的飞行试验,飞机每次的起降都会消耗大量的燃油、产生巨大的噪声。为了降低适航审定成本,减少噪声对机场周围环境的影响,基于中国民航局航空器型号和适航合格审定噪声规定,对某型飞机的起飞和进近噪声数据和起飞降落程序进行分析,得到适航规定接受的等效飞行程序和等效飞行航迹。等效飞行航迹的得出和使用,既降低了国产大飞机在适航审定过程中的适航成本和噪声污染,又为工程技术人员在新型飞机的噪声适航审定过程中提供了一种可参考的办法。
英文摘要:
      It is known that repeated flight tests are needful for Airworthiness Certification of civil aircraft noise.However,each time of takeoff and landing of the aircraft consumes large amount of fuel and produces loud noise.In order to reduce the cost of airworthiness certification and the noise impacting on airport environment,based on the CAAC aircraft types and the regulations of airworthiness certification of aircraft noise,a certain aircraft's takeoff and approaching noise data and the corresponding takeoff and landing procedures are analyzed to get the equivalent flight procedures and paths,which can be accepted by the airworthiness certification.The use of the obtained equivalent flight paths is of great significance for reducing the cost of the airworthiness certification for domestic aircraft and the noise pollution of airport environment.
