Title:
METHOD AND SYSTEM FOR ACTIVELY CONTROLLING CENTER OF GRAVITY OF AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2024/082392
Kind Code:
A1
Abstract:
A method and system for actively controlling the center of gravity of an aircraft, the method comprising: before an aircraft takes off, acquiring heading centers of gravity of a rear water tank (01) and a front water tank (02) on the aircraft, and heading centers of gravity of a front wastewater tank (03) and a rear wastewater tank (04) on the aircraft; setting a target heading center of gravity of the aircraft according to flight characteristics of the aircraft; during flight, calculating the difference in center of gravity (ΔXCG) between the current heading center of gravity of the aircraft and the target heading center of gravity when the center of gravity of the aircraft is changed; when ΔXCG is less than 0, water in the front water tank (02) being consumed by a user, and discharging wastewater in the user into the rear wastewater tank (04); and when ΔXCG is greater than 0, water in the rear water tank (01) being consumed by the user, and discharging wastewater in the user into the front wastewater tank (03). The described method and system are simple and reliable, and the center of gravity of an aircraft can be easily kept within an expected ideal range.
