Problems solved by technology

For the situation that the engine stops in the air due to a failure during the flight, there is no protective measure, and the result of this situation is almost always that the aircraft falls from the air, making the aircraft scrapped

Embodiment Construction

[0021] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, in the unmanned rotorcraft engine air parking protection device of the present invention and its aircraft embodiment, the engine air parking protection device includes a first monitoring device 1, a control device 2, a landing protection device 3 and a height detection device 4, wherein The first monitoring device 1 is used for monitoring the rotation situation of its rotor main shaft and outputs the first monitoring signal when this rotor main shaft rotates normally; Because the rotor of unmanned rotorcraft is driven by its main shaft rotation, therefore, the main shaft rotates normally, The rotation of the rotor is usually normal; the control device 2 is used to receive the first monitoring signal output by the first monitoring device 1, and output a control signal when the first monitoring signal is abnormal, and the ...

Abstract

The invention relates to an unmanned rotor aircraft engine in-flight shutdown protection device, which comprises a first monitoring device, a control device and a landing protection device. The first monitoring device is used for monitoring the rotor rotation and outputting a first monitoring signal when the rotor rotation is normal; the control device is used for receiving the first monitoring signal output by the first monitoring device, and outputting a control signal when the first monitoring signal is abnormal; and the landing protection device is used for receiving the control signal and opening a parachute under the action of the control signal. The invention also relates to an unmanned rotor aircraft which is provided with the engine in-flight shutdown protection device. The unmanned rotor aircraft engine in-flight shutdown protection device and the aircraft thereof have the advantages that: the aircraft can also slowly land under the condition of losing power, so the aircraftdue to falling cannot be scrapped.

Description

technical field [0001] The invention relates to the field of aviation, more specifically, to an unmanned rotorcraft engine air parking protection device and its aircraft. Background technique [0002] Unmanned rotorcraft has been widely used, and it is widely used in military, industrial and civilian fields. However, the research on its failure in the air is relatively lagging behind. Usually, people think that it can only be checked and maintained before it takes off to ensure that it does not break down during the flight. For the situation that causes its engine to stop in the air due to failure during flight, then there is no protective measure, and the result of this situation is almost all that the aircraft falls from the air, so that the aircraft is scrapped. Therefore, it is necessary to protect the unmanned rotorcraft when it is parked in the air, so that even if the aircraft is parked in the air, it will not cause the aircraft to be scrapped due to falling, t...
