The invention discloses a helicopter model weight, gravity center and rotational inertia adjusting method. A typical balance weight and a matrix balance weight are arranged in a helicopter model, and a Z-direction balance weight and an X-direction balance weight are arranged outside the helicopter model; the typical counterweight is located at the front part of the helicopter model and is blocky; the matrix counter weight is located in the middle of the helicopter model and comprises a blocky base counter weight, and mounting grooves are uniformly distributed in the upper portion of the base counter weight in an array mode and used for mounting unit counter weights; the Z-direction counter weight is located at the middle axis position of the helicopter model nose and is installed on the Z-direction screw in a position-adjustable mode, and the Z direction is the height direction; the X-direction counter weight is located at the middle axis position of the helicopter model tail and is installed on the X-direction screw in a position-adjustable mode, and the X direction is the longitudinal direction; the overall weight is adjusted to meet the requirement by increasing or decreasing the individual weight and/or the number of the counterweights, and then the gravity center and the rotational inertia are synchronously adjusted by adjusting the positions of the counterweights. The method can simply, conveniently and efficiently adjust the weight, the gravity center and the rotational inertia of the helicopter model.

    本发明公开一种直升机模型重量、重心、转动惯量调节方法,在直升机模型的内部设置典型配重和矩阵配重、外部设置Z向配重和X向配重;典型配重位于直升机模型前部,呈块状;矩阵配重位于直升机模型中部,包括呈块状的基座配重,基座配重上部阵列均布有安装槽,安装槽用于安装单元配重;Z向配重位于直升机模型机头的中轴位置,位置可调地安装在Z向螺杆上,Z向为高度方向;X向配重位于直升机模型机尾的中轴位置,位置可调地安装在X向螺杆上,X向为纵向;先通过增减各个配重的个体重量和/或数量调节整体重量至符合要求,再通过调节各个配重的位置同步调节重心和转动惯量。本方法可以简便高效的实现直升机模型的重量、重心、转动惯量的调整。
