Abstract

The invention relates to a fuel oil accurate motion space model modeling method, and belongs to design research in weight direction in the field of aircraft conceptual design. With respect to the fuel oil accurate motion space model modeling method, conventional ideas are broken through, and the creation of a fuel oil accurate motion space model is achieved. Effective models are screened and edited, then the effective models are integrated according to the assembly level, an accurate non-fuel-oil space in the fuel tank is obtained, and furthermore the fuel oil accurate motion space model is calculated. Problems that the creation of the fuel oil accurate motion space model is high in difficulty level, large in workload and long in consuming time, the requirement on hardware equipment is high and the like are solved, and strong support can be provided for fuel oil weight characteristic analysis.

Description

technical field [0001] The invention relates to the technical field of weight control in the overall design of an aircraft, in particular to a modeling method for an accurate motion space model of fuel. Background technique [0002] In the analysis of the weight characteristics of the whole aircraft, the calculation of the weight characteristics of fuel (weight, center of gravity, moment of inertia, etc.) plays an important role and is an important factor affecting the flight quality of the aircraft. Changes in fuel weight characteristics lead to changes in overall aircraft weight characteristics. Therefore, in the process of aircraft design, in order to analyze the change range of the center of gravity under various flight profiles and the calculation of load conditions, it is necessary to conduct an in-depth and detailed analysis of the change in fuel weight characteristics. [0003] In the research stage of aircraft design, the key to the analysis of fuel weight characte...
