The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a self-adaptive cooling air inlet channel and a helicopter, specifically, a circular sliding rail and a wind scooper are arranged on the side face of a fuselage, a rudder sheet is arranged on the wind scooper, and the wind scooper introduces airflow near the fuselage into the fuselage and blows the airflow to cooling fins of an engine. When the direction of incoming flow or rotor wing downwash airflow changes, airflow blows to the rudder sheet to generate rotation torque in the corresponding direction, the wind scooper is driven to automatically point to the incoming flow direction, the opening direction of the cooling airflow inlet channel is automatically adjusted under the condition that the weight and energy consumption of the fuselage are not increased, and the opening direction automatically points to the incoming flow direction of external airflow of the unmanned aerial vehicle. No extra power is consumed, the cooling effect of external airflow is fully utilized, and the cooling efficiency is improved.
本发明属于无人机技术领域,具体涉及一种自适应冷却进气道和直升飞机,具体的,本发明提出在机身侧面设置圆形滑轨和导风罩,所述导风罩上设置有舵片,导风罩将机身附近的气流引入机体内部,吹向发动机散热片。当来流或旋翼下洗气流方向改变时,气流吹向舵片产生相应方向的转动力矩,带动导风罩自动指向来流方向,在不增加机身的重量与能耗的情况下,实现自动调节冷却气流进气道开口方向,使开口方向自动指向无人机外部气流的来流方向,不额外消耗功率,充分利用外部气流的冷却作用,提高冷却效率。
