Abstract

The invention discloses an airplane gravity center automatic regulation system, which comprises a center display control sub system and an antifreezing solution balancing sub system connected with the center display control sub system, wherein the center display control sub system comprises a control cabinet arranged in an airplane passenger cabin and a gravity center display touch screen arranged in a cab; an integral work station, a PLC (programmable logic controller) and an AD (analog-to-digital) conversion module are arranged in the control cabinet; the output end of the PLC is connected with the AD conversion module and is then connected with the integral work station. The invention also discloses a regulation method of the airplane gravity center automatic regulation system. The problem of large airplane gravity center position change range in the airplane flying process in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of center-of-gravity adjustment in aircraft type test flight, and in particular relates to an automatic center-of-gravity adjustment system of an aircraft. The invention also relates to an adjustment method of the automatic center-of-gravity adjustment system of an aircraft. Background technique [0002] During the flight of the aircraft, the position of the center of gravity of the aircraft (especially the longitudinal center of gravity) directly affects the maneuverability and stability of the aircraft. Since the two have their own important functions, and their requirements on the center of gravity position are exactly opposite, the position of the center of gravity of the aircraft must be in an appropriate and small range of change. During the flight, the center of gravity of the aircraft often deviates from the safe range due to many factors such as aircraft attitude changes, fuel consumption, external ...
