直升机能作各种姿态飞行,主要靠旋翼.由于旋翼工作原理和构造的独特性,使得直升机与一般飞机在空气动力,操纵性等方面有许多不同的特点,主要表现为,飞行中空气动力响应复杂,操纵反应迟缓协调动作多,难度大,加上直升机的稳定性较差,因而直升机驾驶员操纵飞机困难.武装直升机能否执行对地攻击任务?攻击的机会及可持续射击的时间有多长?就是本文的主要研究目的. Helicopters can make a variety of attitude flight, mainly by the rotor.As the working principle of the rotor and the unique structure, making the helicopter and the general aircraft in aerodynamics, maneuverability, etc. There are many different characteristics, mainly as aerodynamic response Complex, slow response Manipulation Coordination and more difficult, coupled with the poor stability of helicopters, helicopter pilots control of the aircraft difficult. Helicopter gunships can perform on-site attack mission? Attack opportunities and sustainable shooting time Long? This is the main purpose of this study.
