This paper presents one kind of aggregation for linear system modal reduction. The aggregational matrix of reduced system is given bythe solution of a general Lyapunov equation——SA11-A22S-A21 =0,in whichA11, A21 and A22 are the block matrices of the parameter matrix of initial linear system. Matrix ( -S I) is the aggregational matrix. Then, by means of the method given above, the linearized dynamic equations of longitudinal motion and lateral-directional motion of aircraft are separated, and the approximate...

This paper presents one kind of aggregation for linear system modal reduction. The aggregational matrix of reduced system is given bythe solution of a general Lyapunov equation——SA11-A22S-A21 =0,in whichA11, A21 and A22 are the block matrices of the parameter matrix of initial linear system. Matrix ( -S I) is the aggregational matrix. Then, by means of the method given above, the linearized dynamic equations of longitudinal motion and lateral-directional motion of aircraft are separated, and the approximate formulas of phugoid, short period, roll-spiral and Dutch-roll modes are derived. Some calculation results show that the approximate formulas have a goad precision, espscially increasing the estimation accuracy for the dampings of phugoid and Dutch-roll modes.

本文给出一种处理线性系统降阶的集结方法,并根据该方法将飞机纵向运动方程和横侧向运动方程进行降阶分解,得到了飞机的沉浮、短周期、滚转-螺旋和荷兰滚运动模态的各近似式,结果表明本文中的各近似式精度较好,特别是提高了沉浮及荷兰滚阻尼的估计精度。

First the related condition which causes the non symmetric thrust flight and the control method under the circumstances of the non symmetric thrust flight are stated, the relationship between the non symmetric thrust flight and the minimum control speed is pointed out. Then, the calculating formulas of minimum control speed on the ground and in the air are conducted by using the non symmetric thrust flight's lateral directional motion formulas.

First the related condition which causes the non symmetric thrust flight and the control method under the circumstances of the non symmetric thrust flight are stated, the relationship between the non symmetric thrust flight and the minimum control speed is pointed out. Then, the calculating formulas of minimum control speed on the ground and in the air are conducted by using the non symmetric thrust flight's lateral directional motion formulas. The calculating results show the different mainly depends on non symmetric thrust moment formed by the operative engine. At last, the factors which reflects the minimum control speed are analysed and the control characteristics of the non symmetric thrust flight while taking the minimum control speed into consideration are pointed out. It can serve to the research of the non symmetric thrust flight problem and the actual flight.

This paper gives the concept of UAV's static stability and the influences of the relaxed directional static stability on its lateral-directional motion. It studies and compares three compensative ways of the relaxed directional static stability UAV with flight control system, including the sideslip angel feedback, and the yaw rate and lateral acceleration feedbacks.
