Abstract

The present invention proposes a method for determining the position of the center of gravity of an analytically hanging weighing aircraft and its compound weighing device. By using the compound analytical weighing method of the present invention in combination with the hanging weighing method and its compound weighing device, it is only necessary to One time of horizontal weighing and one time of hanging, the position of the center of gravity of the aircraft in three directions can be obtained. The present invention is achieved through the following technical solutions. Use the compound weighing device with three-dimensional adjustable three-point support to adjust the plane level, and pass the known coordinates of the front support and the rear support, through the pressure sensors of the front scale and the rear scale on the compound weighing device From the readings, the position of the center of gravity of the aircraft heading is calculated. Suspend the aircraft on the truss by a sling, install an inclination sensor between the sling and the rear support, and measure the relative angle between the axes of the above sling and the rear support in the pitch and yaw directions through the inclination sensor; according to "Aircraft Calculate the position of the center of gravity of the aircraft in the vertical direction and yaw direction by using the drawing method in the Design Manual.

Description

Method for determining the position of the center of gravity of an analytically suspended weighing aircraft and the technical field of a compound weighing device The present invention relates to a kind of method for determining the center of gravity position of small-sized aircraft, and the present invention also relates to weighing aircraft in this method Heavy compound weighing device. Background technique At present, the method for determining the position of center of gravity of small aircraft mainly adopts the publication in October, 1999 by Aviation Industry Press Chapter 8 of Volume 8 of "Aircraft Design Manual" describes methods such as drawing method and analytical method. The graphing method described therein is the general By supporting the wheels, change the attitude of the aircraft three times, measure three sets of defined related geometric dimensions, and then make The position relationship between the average aerodynamic chord and the measured size is ...
