Abstract

The invention discloses airship center of gravity measurement equipment and a measurement method. The equipment comprises a computer, two electronic scales, a fixing band capable of being fixed to the airship, a fixing rack arranged on the ground and several sensors. Because during a manufacturing process of the airship, a width direction is designed according to a completely symmetrical mode, only the center of gravity along a length direction needs to be measured. By using the airship center of gravity measurement equipment, after the airship is fixed, the several sensors are used to carry out position determination and finally a center of gravity position of the airship is positioned.

Description

【Technical field】 [0001] The invention belongs to the field of aviation, and in particular relates to an airship center-of-gravity measuring device and a measuring method. 【Background technique】 [0002] An airship is a lighter-than-air aircraft that mainly relies on the buoyancy provided by the airbags filled with hydrogen or helium to support the airship and its load in the air during flight. , is more and more widely used in the military and civilian fields, and the buoyancy of the airship is controlled by filling and exhausting the main airbag of the airship with helium or air through the auxiliary airbag, but the gas distribution of the main airbag will change after the airbag is inflated and exhausted. , leading to changes in the center of gravity of the airbag, especially along the length direction, which will cause changes in the attitude of the airship, which will bring certain hidden dangers to the flight safety of the airship, and will also affect the economy of t...
