俄罗斯海军航空兵大规模装备和应用的共轴双旋翼直升机虽然在技术上存在很多极具吸引力的优势和特点,但是直到目前仍然无法动摇常规尾桨式直升机的统治地位。共轴双旋翼直升机在结构上与常规尾桨式直升机存在很大的区别,前苏联/俄罗斯海军舰载直升机普遍采用共轴双旋翼直升机,而常规尾桨式的米-14 Coaxial twin-rotor helicopters, which are large-scale installations and applications of Russian naval air forces, have many unsurpassed advantages and features in technology but have not been able to shake the conventional tail rotor-type helicopters until now. Coaxial twin-rotor helicopters structurally conventional tail rotor helicopters there is a big difference, the former Soviet Union / Russian naval carrier-based helicopters commonly used co-axial twin-rotor helicopters, while conventional tail rotor-type Mi-14
