Problems solved by technology

According to the statistics, the farthest distance from the end point of the third stage to the end of the runway is about 45 kilometers. It can be understood that the main control obstacles affecting the take-off performance are mainly concentrated within the range of about 45 kilometers from the end of the runway. For obstacles exceeding 45 kilometers, that is, terrain or obstacles on an ultra-long path, the performance software of Boeing or Airbus models has not been specifically designed and considered

Abstract

The invention discloses an airplane takeoff performance optimization method and system based on an ultra-long obstacle crossing path. The airplane takeoff performance optimization method comprises thefollowing steps: striking out a first stage, a second stage, a third stage and a fourth stage according to the process from departure obstacle crossing flight to final high-altitude level flight of an airplane; equivalently converting the far-end obstacle data under the ultra-long path in the fourth stage into the third stage, and simulating and adding virtual obstacle data in the third stage; and calculating the take-off carrying capacity of the aircraft by the aircraft performance calculation software according to the real obstacle data in the second stage, the real obstacle data in the third stage and the virtual obstacle data. According to the airplane takeoff performance optimization method, the take-off load capacity and the more reasonable obstacle crossing climbing track of the aircraft are comprehensively calculated according to the real obstacle data of the second stage, and the real obstacle data of the third stage and the virtual obstacle data; more reasonable and more objective take-off carrying capacity can be obtained under the condition that obstacle crossing safety is guaranteed, and the operation economic benefits of airlines are improved.

Description

technical field [0001] The invention relates to a method for optimizing the take-off performance of an aircraft under the requirement of overcoming obstacles, in particular to a method and system for optimizing the take-off performance of an aircraft based on an ultra-long obstacle overcoming path. Background technique [0002] Before the release of each flight, the airline needs to provide a performance analysis table for the aircraft in operation at a certain airport. The table gives details of the take-off weight, V1, VR, and V2 speeds of the operating model under various temperature conditions, take-off configurations, and QNH correction conditions, and provides data for the crew to control the total take-off weight and input aircraft The flight management computer (FMC) prepares for the flight. [0003] According to the requirements of the regulations, when the aircraft fails with one engine, the extreme weight and high temperature conditions, such as figure 1 As show...
