英国威斯特兰公司希望于今年底发起一种先进的组合式直升机(ACH)技术验证机研制计划.该机将以威斯特兰研制的“山猫”直升机为基础,在其上安装机翼和改进的罗罗/透博梅卡公司研制的RTM322发动机.其主要设计特点是在“山猫”直升机的机体上增装一副机翼,以达到为旋翼卸载和提高前飞速度的目的.与“山猫”相比,该机的前飞速度提高50%,达到250节;飞行高度达到6100米;升阻比提高25%～50%;有效载荷和航程比提高20%,并且全寿命成本降低10%～20%.机上装的机翼具有后缘襟翼,以改变它的组合升力效应.一副可动式平尾用来调整因襟翼引起的俯仰力矩,一个可调式方向舵在飞机高速飞行时将起到为尾装卸载的作用.旋翼系统将采用威斯特兰公司的BERP桨叶,它
Westland, UK, hopes to launch an advanced ACH technology demonstrator development plan later this year based on the Bobcats helicopter developed by Westland, And improved Rolls-Royce Turckmec RTM322 engine developed by its main design features in the “Bobcats” helicopter body with an additional wing, in order to achieve the rotor unloading and to improve the speed of the former flight. Compared to Bobcat, the aircraft’s forward speed is increased by 50% to 250 knots; flight height is 6,100 meters; lift-resistance ratio is increased by 25% -50%; payload and cruise ratio are increased by 20% and life-cycle costs are reduced 10% to 20%. The upper wing has trailing edge flaps to change its combined lift effect. A movable tail is used to adjust the pitch moment caused by the flaps, an adjustable rudder is flown at high speed Will play the role of tail loading and unloading. Rotor system will use Westland’s BERP blade, which
