Abstract

The invention provides forced ventilation mechanisms of a rotorcraft cabin and a rotorcraft and relates to the technical field of aircrafts. According to the forced ventilation mechanisms, the technical problem that in the prior art, a circulating ventilation system of the rotorcraft is complex in structure is solved. Each forced ventilation mechanism of the rotorcraft cabin comprises a ventilation openings and ventilation opening blocking pieces. The ventilation openings are formed in a cabin door or the cabin wall of the rotorcraft, and the ventilation opening blocking pieces are movably connected to the ventilation openings; the ventilation opening blocking pieces can move to the positions where the ventilation openings are closed and the positions where the ventilation openings are opened; and air in the rotorcraft cabin and air outside the rotorcraft cabin can flow freely through the opened ventilation openings. The ventilation openings are formed in the cabin door or the cabin wall of the rotorcraft to conduct forced ventilation; the structure is simple; the ventilation effect is direct; ventilation is fast; and the ventilation opening blocking pieces are movably arranged on the ventilation openings, so that opening and closing are convenient, and operation is more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a forced ventilation mechanism for a rotor cabin and a rotorcraft. Background technique [0002] A gyroplane is a rotorcraft that utilizes the relative airflow during forward flight to blow the rotor to rotate to generate lift. Its forward force is directly provided by the engine driving the propeller. It is an aircraft between a helicopter and an airplane, equipped with a rotor and a fixed wing. It has the characteristics of short take-off and landing distance, low-speed and low-altitude flight, simple and lightweight, and easy to conceal, but it cannot take off and land vertically, and cannot hover. It can be used for aerial photography, weapon launch, battlefield reconnaissance, etc. [0003] Gyroplanes and helicopters are exactly the same in appearance, but in essence, gyroplanes and helicopters are two completely different aircrafts. Cyclogyro is actually a kind of airc...
