A method for simulating the flight process of an aircraft

Abstract

The invention relates to a simulating method for a flying process of an air craft. The simulating method comprises the following steps: obtaining initial parameters of a secondary starting moment t of a standard orbiting aircraft; performing navigation computation to obtain inertial navigation parameters of the moment t; calculating propelling force curve compensation parameters of the moment t; performing inertial navigation computation by utilizing gyroscope data of the inertial navigation equipment and data output by an accelerometer in real time, and simulating orbital data from 0 to moment t; obtaining the parameters of the moment t, performing compensation and taking the parameters as initial parameters of a propelling force curve section, performing inertial navigation computation until flying is ended, and obtaining the orbital data from the moment t to the flying ending section, thereby completing flying simulation after a propelling force curve is accessed. According to the simulating method, true inertial group data is adopted to perform inertial navigation simulation before the secondary starting moment, and propelling force curve stimulation is adopted after the secondary starting moment, so that the true rail can be stimulated, true inertial unit characteristics are reflected, error conditions in practical flying is closer, and therefore, ground test is more true and reliable.

Description

technical field [0001] The invention relates to an aircraft flight process simulation method, which belongs to the field of aircraft ground tests. Background technique [0002] The carrier needs to verify the various technologies and stand-alone products used during the flight before the flight. Therefore, it is necessary to use the simulated flight test to comprehensively assess the flight process, guidance and control process and hardware system of the carrier. Some flight simulation methods often mainly use software calculation and simulation, without considering the real inertial group information, and cannot assess the error influence of the real inertial group in the deviation state. How to realize the track simulation closer to the actual flight state in the ground test is a technical problem to be solved urgently in this field. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a kind o...
