Abstract
The utility model discloses a helicopter with an elevation assisting device. The helicopter comprises a main body of the helicopter (3), a main rotor wing (4), a pair of stub wings (2) and two ducted-type assisting fans (1), wherein the stub wings (2) are fixed on two sides of the cabin of the main body (3); the ducted-type assisting fans (1) are rotatably connected with tail ends of the stub wings (2); and the two ducted-type assisting fans (1) are respectively connected with engines. Functioning as the elevation assisting device, the additional pair of stub wings and the two ducted-type assisting fans provide the helicopter with an auxiliary elevation force, so as to shorten the take-off time.
Description
(1), technical field
The utility model relates to a kind of helicopter, specifically a kind of helicopter with lift assisting device.
(2), background technology
Thereby existing helicopter drives main rotor rotation drive helicopter by driving engine and takes off, because engine power deficiency, main rotor need rotate the long period helicopter usually and just can take off, and the waste regular hour, existing helicopter does not have lift assisting device to be used to help helicopter to take off.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of helicopter with lift assisting device is provided, and the departure time shortens, and saves time, and improves flying speed, to overcome the defective of existing helicopter.
In order to solve this technical matters, the utility model has adopted following technical scheme:
A kind of helicopter with lift assisting device, comprise helicopter main body and main rotor, it is characterized in that: also comprise a secondary short limb and two duct formula booster fan, described short limb is fixed on the both sides, cabin of helicopter main body, described duct formula booster fan is rotatably connected to the end of short limb, and two duct formula booster fan are connected with driving engine respectively.
Good effect of the present utility model is: by installing a secondary short limb and two duct formula booster fan additional as lift assisting device on the basis of original helicopter, for helicopter provides auxiliary lifting, shorten the departure time of helicopter, also increased the load-carrying ability and the flying speed of helicopter simultaneously.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.
(5), the specific embodiment
Below in conjunction with accompanying drawing and embodiment is provided, the utility model is further described.
As shown in Figure 1, this example comprises helicopter main body 3 and main rotor 4, also comprises a secondary short limb 2 and two duct formula booster fan 1 that are connected with driving engine, and described short limb 2 is fixed on the both sides, cabin of helicopter main body 3, is positioned at the below of main rotor 4.Described duct formula booster fan 1 is connected the end of short limb 2 by rotating shaft, can do 90 ℃ of rotations around short limb 2.
When taking off, two duct formula booster fan 1 spouts provide lift upwards for helicopter downwards; Behind the helicopter built on stilts, two duct formula booster fan 1 are rotated to horizontal direction by vertical direction, and lift carries out the transition to horizontality by thrust forward, for flight provides auxiliary power.
Claims (1)
1. helicopter with lift assisting device, comprise helicopter main body (3) and main rotor (4), it is characterized in that: also comprise a secondary short limb (2) and two duct formula booster fan (1), described short limb (2) is fixed on the both sides, cabin of helicopter main body (3), described duct formula booster fan (1) is rotatably connected to the end of short limb (2), and two duct formula booster fan (1) are connected with driving engine respectively.
