Description
技术领域technical field

背景技术Background technique
倾转旋翼飞机是一种性能独特的飞机，它可以像传统多旋翼飞机进行悬停、垂直起降，也可以像螺旋桨固定翼飞机那样高速巡航飞行。该飞行器具有垂直起降、悬停、低空飞行、高速巡航及较远的航程的能力，能在较为复杂的地形、环境中快速升空，完成较远距离的飞行任务，可以在战场侦察及抢险救灾中发挥特定作用，具有广阔的应用前景。A tiltrotor aircraft is a unique aircraft that can hover, take off and land vertically like a traditional multi-rotor aircraft, or cruise at high speed like a propeller fixed-wing aircraft. The aircraft has the capabilities of vertical take-off and landing, hovering, low-altitude flight, high-speed cruising, and long range. It can quickly lift into the air in relatively complex terrain and environments, complete long-distance flight missions, and can conduct reconnaissance and emergency rescue on the battlefield. It plays a specific role in disaster relief and has broad application prospects.
目前大多数倾转旋翼飞机在倾转过程中，高速转动的桨叶将在与飞机平飞的不同方向上产生较大分力，造成飞机姿态不稳定。而很多倾转旋翼飞机在平飞状态时，尾部的电机停转且不倾转，由此在平飞时产生较大的空气阻力，影响飞行航程和飞行速度。At present, during the tilting process of most tilt-rotor aircraft, the high-speed rotating blades will generate large force components in different directions with the aircraft in level flight, resulting in unstable attitude of the aircraft. However, when many tilt-rotor aircraft are in level flight, the motor at the tail stops and does not tilt, thus generating greater air resistance during level flight, which affects the flight range and flight speed.
