Embodiment Construction

[0015] The following structural drawings further describe the present invention:

[0016] Such as figure 1 As shown, the helicopter includes a fuselage, a fairing, an emergency device, a propeller, a main power device, a seat, a tail and a main control device. The present invention mainly improves the helicopter emergency device: it includes a strut 3 and a parachute 5 arranged in the nose part of the fairing 4, and a sleeve connected to the strut 3, and the sleeve is sleeved at the head end of the strut 3. A positioning electric plug 2 is inserted between the two, a compression spring 1 is installed between the sleeve and the support rod 3, and the electric plug 2 is connected to the control circuit. The parachute 5 is connected to the strut 3, and when the fairing 4 flies out, the parachute 5 will be taken out and opened. Take the helicopter and land slowly to prevent damage to the helicopter.

[0017] The control circuit includes: a power supply, a control switch 10, and an el...

Abstract

The invention provides a helicopter emergency device which reduces the loss when a helicopter has failure, greatly reduces the workload of detection and maintenance and saves the cost. The emergency device comprises a stay bar and a parachute which are arranged in a fairing of a head part as well as a sleeve connected with the stay bar; the sleeve is sleeved at the head end of the stay bar; an electric sliding bolt is arranged between the sleeve and the stay bar in an insertion mode; a compression spring is arranged between the sleeve and the stay bar; and the electric sliding bolt is connected to a control circuit.

Description

Technical field: [0001] The invention relates to a helicopter emergency device, which belongs to the technical field of aircraft. Background technique: [0002] Helicopter is a kind of airplane. The biggest difference from other airplanes is that one or more large horizontally rotating rotors provide upward lift. The helicopter can do low-altitude (several meters above the ground), low-speed (from hovering) and the same nose direction maneuvering flight, especially vertical take-off and landing, it does not need a runway, it can take off and land vertically in a narrow field. [0003] Existing helicopters do not have emergency devices. When uncontrollable failures occur during flight, such as damage to the power system, motor stalls, etc., the helicopter is prone to fall damage, causing great economic losses. Summary of the invention: [0004] Aiming at the problems of the existing helicopters, the present invention provides a helicopter emergency device, which reduces the loss ...
