Abstract

The invention provides an airplane continuously descending approach locus obtaining method and device; the method comprises the following steps: building an airplane descending locus model, an airplane dynamics model and an airplane oil consumption model, wherein the airplane descending locus model is used for representing an airplane descending process having three phases; building a first objective function based on fuel quantity according to the airplane descending locus model, the airplane dynamics model and the airplane oil consumption model; discretizing the first objective function so as to obtain a second objective function; using a difference evolution algorithm and sequence secondary planning algorithm combined method to solve the second objective function, thus obtaining the airplane continuously descending approach locus corresponding to the second objective function optimal solution. The airplane continuously descending approach locus obtaining method and device can obtain the airplane continuously descending approach locus with high accuracy and efficiency.

Description

technical field [0001] The invention relates to the technical field of aircraft operation, in particular to a method and device for acquiring an aircraft continuous descent approach trajectory. Background technique [0002] Under the condition of limited airspace, the increasing number of flights has exacerbated the congestion and delay of the airspace, especially when the aircraft is over the airport terminal area, the circling and waiting of the aircraft has brought serious environmental problems such as noise pollution and exhaust pollution. Continuous descent approach (Continuous Descent Approach / Arrival, CDA), as a new method of aircraft approach and descent, has a remarkable effect in reducing the impact of noise on the ground. Under the operating concept of CDA, the aircraft maintains a longer flight time at the cruising altitude than the traditional ladder descent method, and the engine uses idle thrust during the descent process to minimize the low-altitude level fl...
