Method for designing and evaluating center of gravity of airplane

Abstract

The invention discloses a method for designing and evaluating the center of gravity of an airplane, belongs to the field of airplane weight engineering, in particular to a method for designing and evaluating the center of gravity of the airplane visually. The method is characterized by comprising the following steps of 1, defining an airplane layout border, and completing conversion from an airplane plane layout coordinate system to an airplane body coordinate system; 2, evaluating the center of gravity of a part. The method has the advantages that the center of gravity of the part of the airplane is visually edited and the evaluation on the center of gravity of the airplane is displayed in real time. Compared with the traditional method, the method has the advantage that the computational accuracy and the computational efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the field of aircraft weight engineering, and in particular relates to a visual aircraft center of gravity design and evaluation method. Background technique [0002] All objects on Earth are affected by gravity. Each component, system equipment, fuel, passengers, cargo, etc. of the aircraft are also affected by gravity, and the resultant point of gravity is the center of gravity of the aircraft. [0003] The position of the center of gravity of the aircraft will change continuously due to different cargo loading positions and fuel consumption, material delivery, and weapon launch during mission execution. The change of the center of gravity of the aircraft must be controlled within the allowable range, otherwise it will affect the safety of the aircraft. Therefore, the position of the center of gravity of the aircraft must be strictly controlled during the aircraft design process. [0004] In the aircraft design phase, the ...
