An Analysis and Design Method of Continuous Descent Operation Program

Abstract

The invention discloses a continuous descent operation program analysis and design method. The method comprises the following steps of: establishing an aircraft intention model according to an initially designed continuous descent operation program, a navigation point coordinate and a database encode table; selecting a typical type, considering the aircraft quality and the uncertainty of wind speed and wind direction, and generating an aircraft four-dimensional flight tracks on the basis of an aircraft particle model, the aircraft intention model and an aircraft basic performance database; and analyzing the distribution of heights and speeds of various aircrafts passing through waypoints under an uncertain condition and spacing distribution between the adjacent aircrafts during the matching between different types on the basis of a series of generated aircraft four-dimensional flight tracks, and judging whether the initial design of a CDO program is proper or not and whether the current control handover interval is reasonable or not, so as to guide the design and modification of the CDO program. According to the method disclosed by the invention, the disadvantages of the existing CDO programs are overcome, and CDO programs which have certain advantages in the aspects of energy saving, emission reduction and noise reduction are designed.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to an analysis and design method of a continuous descent operation program. Background technique [0002] In recent years, with the intensification of the energy crisis and the strengthening of environmental protection awareness, problems such as fuel consumption, airport noise, and exhaust emissions have become increasingly prominent. On the premise of safe operation, how to reduce fuel consumption as much as possible, alleviate airport noise, and reduce exhaust emissions have become the focus of attention of the civil aviation industry. The continuous descent operation procedure (Continuous Descent Operation, CDO) is based on the above background, and it was first proposed and applied in the developed countries of aviation. At present, the CDO technology in the United States, the Netherlands, Singapore and other countries is relatively mature, and it has been o...
