Abstract

Abstract: Cruising phase is the important stage for aircraft performance optimization. This paper introduces a method of simultaneous optimization of multi-objective such as flight fuel cost, time cost, and shortest re-planning path under the constraints of hazardous environment, into trajectory planning for cruising phase. A dynamic optimization model of the route under hazardous weather and a performance optimization model for cruising phase of the vertical profile are established, and intelligent algorithms are used to solve them. Taking a certain route as an example, a dynamic real-time optimization route is generated by using the dynamic route optimization model. Combining with the performance data of a certain type of aircraft, the performance optimization model of the cruising phase is used to optimize its performance of cruising phase. In the end, this paper verifies the optimization results of the multi-objective optimization algorithm for route and performance.
