Embodiment Construction

[0020] The present invention is described in further detail below: a kind of aircraft cruising equal-minute fuel consumption envelop comprehensive chart calculation and generation method mainly consists of two parts:

[0021] 1) Establish cruising flight dynamics equation, calculate and solve the cruising minute fuel consumption at each altitude and speed state point with cruising altitude and cruising speed two-dimensional cycle;

[0022] First, based on the overall parameter data, aerodynamic data, engine data, etc. of an aircraft, and according to the flight dynamics characteristics of cruise flight, the dynamic equation of aircraft cruise and level flight is established;

[0023] Secondly, according to the given initial parameter conditions, such as the mass of the aircraft, the flight height, and the flight speed, the circular iterative calculation is used to solve the equation of motion for cruising and level flight, and the thrust required for the level flight of the air...

Abstract

The invention relates to an aircraft cruising equal-minute fuel consumption envelope comprehensive chart calculation and generation method, and belongs to the technical field of aviation. The aircraft cruising equal-minute fuel consumption envelope comprehensive chart calculation and generation method is characterized by comprising the following steps: 1, establishing a cruising flight kinetic equation, calculating and solving cruising minute fuel consumption under each height and speed state point in a two-dimensional cycle manner according to cruising height and cruising speed, taking different cruise height points and different speed points as initial conditions to carry out two-dimensional cyclic calculation according to a flight envelope range of an aircraft, and obtaining a cruise minute fuel consumption database in the whole flight envelope range; and 2, generating an equal-minute fuel consumption envelope diagram according to the airplane cruise minute fuel consumption database. The method has the following advantages that a pilot can more visually find out minute fuel consumption data at all heights and speeds, and the pilot can more rapidly plan a cruise flight task.

Description

technical field [0001] The invention relates to a method for calculating and generating a comprehensive chart of an aircraft cruising equal-minute fuel consumption envelope, and belongs to the field of aviation technology. Background technique [0002] When an aircraft is performing a cruise mission during a long voyage, the pilot needs to determine the fuel consumption per minute or hour at a given cruise altitude and cruise speed, and then estimate the possible fuel consumption of the cruise mission based on the flight time of the cruise mission. amount of fuel. At present, the aircraft design department generally calculates the optimal cruising minute fuel consumption at a given altitude based on the capabilities of the aircraft. However, according to different missions or mission changes, pilots often need to obtain minute fuel consumption at other altitudes and speeds for planning other cruising missions. The flight envelope of modern aircraft is very wide, the flight...
