Problems solved by technology
[0003] This support method can reduce the lateral force generated during the jacking up of the aircraft, but it cannot eliminate
The weight sensor is not in strict point contact with the top socket of the aircraft, but a curved surface contact, and the point of action is not accurate
It can only measure the weight and center of gravity of the aircraft in a single attitude, and it is time-consuming and labor-intensive to use the manual jacking method

The invention belongs to the field of aircraft overall design, and particularly relates to variable-attitude aircraft weight gravity center measuring equipment and a measuring method. The measuring equipment comprises: airplane wheel fixing platforms, the number of which is the same as that of airplane wheels of an airplane to be measured and the upper surface of which is used for fixing one airplane wheel; a plurality of lifting mechanisms are vertically arranged at the bottom of each airplane wheel fixing platform 6 and used for supporting and driving the airplane wheel fixing platform to ascend and descend in the vertical direction; the high-precision weight sensors are arranged between the tops of the lifting mechanisms and the bottom of the airplane wheel fixing platform; and the servo motor is used for driving the lifting mechanism to move. According to the variable-attitude aircraft weight gravity center measuring equipment and method, longitudinal and transverse course state adjustment of the aircraft can be achieved, and the equipment and method are superior to a top nest mode; in addition, three sensors are arranged below the wheel, so that the gravity action point of theairplane can be accurately measured and is superior to that of a simple wheel type platform scale; furthermore, aircraft wheels are free to restrain, and lateral force generated in the process superior to the aircraft leveling process is eliminated.
Description
technical field [0001] The application belongs to the field of overall aircraft design, and in particular relates to a weight center-of-gravity measuring device and a measuring method for a variable-attitude aircraft. Background technique [0002] The aircraft weight and center of gravity measuring equipment is the basic equipment of each type of aircraft, which is used for real-time monitoring of the weight and center of gravity during the trial production of the aircraft. The core components of the equipment consist of three sensors that meet the requirements of range and accuracy, an integrated control platform, and a measuring force compensation plate Composition, the measurement is realized by supporting the top socket of the aircraft with a jack. Generally, a three-point support method is adopted. Each support point includes a set of jacks and weight sensors. The jack is hydraulic and gear transmission. It is supported on the ground by three measuring force compensation...
