The aerodynamic forces on any control surface produce a moment about the hinge. 在任何操纵面上的空气动力均产生围绕其铰链轴的力矩。
The aerodynamic terms in the force and moment equations have all been replaced by the state variables of which they are functions and control forces and moments. 力和力矩方程中的空气动力项已经全部用为其函数的状态变量及操纵力和力矩所代替。
