Abstract
The utility model discloses an air-ground helicopter, which is formed by a casing, a propeller, a tail rudder, an aero-engine arranged in the case, an automobile assembly and an attack system, and is characterized in that the casing of the helicopter is arranged on the upper portion of the automobile assembly to form an integrated body. The air-ground helicopter can be usually used as an automobile for saving fuel, and is used as a helicopter at emergency or overstepping barriers, and is convenient and fast. The utility model can be further manufactured into an air-ground helicopter toy with remote control for children, thereby increasing the interests of children for science and technology knowledge.
Description
Technical field
The utility model relates to a kind of aircraft, especially a kind of can hidden screw propeller, the land that on the road surface, can walk, have the armed attack system, empty dual-purpose helicopter.
Background technology
Civilian or the military type helicopter of prior art mostly has only a kind of function of flight at present, when autogyro enters the city proper and need low-latitude flying to carry out tracking target again, because the existence of incity, city electrical network, trees, high-lager building, the autogyro of this simple function just is difficult to finish the work; Secondly, because current oil price is high, aircraft flight runs than automobile and will expend more fuel as you know, if carrying out of task is not very urgent in time, and only use automobile that the obstacle that can't go beyond is arranged, saving fuel and finish the work and constituted a pair of contradiction like this; So providing a kind of can on the way run, the land that can aloft fly, empty dual-purpose helicopter are current urgent tasks that needs solution again.
Summary of the invention
The purpose of this utility model be can on the way run in order to overcome the deficiencies in the prior art, to provide a kind of, can aloft fly again, can also shorten tail vane for reducing resistance when on the way running, the hidden land of screw propeller, empty dual-purpose helicopter.
The technical scheme in the invention for solving the technical problem is:
A kind of land, empty dual-purpose helicopter are made up of casing, screw propeller, tail vane, the aero-engine, automobile assembly and the attacking system that are installed in the casing, and the casing of helicopter is installed in the top of automobile assembly and becomes entity.
The technical scheme in the invention for solving the technical problem can also be:
Screw propeller described in the utility model is a joint formula hydraulically extensible screw propeller.
The transmission shaft of screw propeller of the present utility model is the plunger of the vertical bi-directional expansion plunger cylinder that is provided with.
But the top at casing of the present utility model middle part is two parts of the folding that separated time separates in the slave top, and the size after open on the machine top can make the screw propeller after the withdrawal be withdrawn in the casing.
The folding on machine top, the utility model middle part is driven by the telescopic hydraulic ram that is installed on the casing inner top.
The transmission shaft of tail vane of the present utility model is the piston rod of bi-directional expansion oil cylinder.
Flexible piston oil-cylinder of double-bang firecracker described in the utility model and telescopic hydraulic ram are the independently oil-free box hydraulic system that the bidirectional hydraulic oil pump is installed.
The beneficial effects of the utility model are:
The utility model can be used as automotive use at ordinary times, with fuel saving; Can be used as autogyro usefulness again when maybe needing to go beyond obstacle carrying out an urgent task, convenient and swift; The utility model can also be made into a kind of remote operated children's usefulness land, empty dual-purpose helicopter toy be with, and increases the interest of children to scientific and technological knowledge.
