摘要
The Dash Stop flight at the extreme condition is the primary interest of this study. This paper describes some research on the flight characteristics of helicopter in Dash Stop. A set of equations which govern the Dash Stop is developed. A method which determines the acceleration and deceleration is proposed. Formulas are then developed which relate the aircraft angular rates and attitudes to flight speed, angle of attack and acceleration or deceleration. Finally the DOLPHIN helicopter is taken as an example to calculate its acceleration/deceleration capability, pilot control and aircraft attitudes in space. It is found that the results are reasonable.
主要研究极限状态的迅速进位飞行。文中阐述了直升机迅速进位过程中飞行特性的研究方法，推导了一组确定迅速进位飞行特性的主控方程，给出了与迅速进位有关的最大加速度和减速度的计算方法，建立了直升机在运动过程中的角速度、姿态角与飞行速度、迎角、加（减）速度之间的关系。最后以“海豚”直升机为例计算其最大加速度、最大减速度在迅速进位过程中驾驶员的操纵量、直升机的姿态角和完成迅速进位这一机动动作所需的最短时间和最短飞越距离。
