Flight control method in airplane asymmetric mounting mode

Abstract

The invention discloses a flight control method in an airplane asymmetric mounting mode. The method comprises: S1, the mass m of an asymmetric mounting object and a distance delta y to a symmetric plane of an airplane are obtained from an avionics system; S2, an accelerometer collects an airplane normal overloading value n in real time; S3, asymmetric rolling moment is calculated; S4, according to the rolling moment obtained at the S3, a compensation value for suppressing the rolling moment by using an aileron or a multifunctional spoiler is calculated; and S5, a flight control system drives the aileron or the multifunctional spoiler to make deflection based on the calculation result obtained at the S4 and the rolling moment generated by deflection of the aileron or the multifunctional spoiler cancels the rolling moment generated by asymmetric mounting. According to the invention, the method has the following beneficial effect: on the condition of asymmetric mounting of the airplane, the rolling can be suppressed automatically without manul involvement of any pilot, so that the work load of the pilot is reduced.

Description

technical field [0001] The invention relates to the technical field of flight control, in particular to a flight control method for asymmetrically mounted aircraft. Background technique [0002] In modern aviation, there are often cases of asymmetric lateral mounting of aircraft. For example, combat aircraft launch a weapon on one side and return with the weapon on the other side, or transport aircraft cause oil leakage on one side of the wing due to failure. Mounting asymmetry will cause the center of gravity of the aircraft to deviate from the plane of symmetry, and the aircraft will roll uncommanded and cannot fly as expected by the pilot. [0003] At present, the aileron trim mechanism is generally designed to suppress the above-mentioned rolling moment. Its working principle is: when the pilot presses the trim button, the aileron deflects at a certain rate, and when the pilot releases the trim button, the aileron stops at the current angle. Although this aileron trim m...
