The utility model relates to a vertical take-off and landing hovercar, which belongs to the technical field of aircraft design. The hovercar comprises a ground drive system comprising a car body and wheels; four retraction jacks are mounted on the periphery of the car body by means of rectangular arrangement; two retraction jacks are positioned in front while the other two retraction jacks are positioned on the back; each retraction jack consists of a retraction arm and a hydraulic device; one end of each retraction arm is provided with a rotor wing device while the other end of each retraction arm is hinged onto the car body; one end of each hydraulic device is also hinged onto the car body while the other end of each hydraulic device is hinged to the middle of the corresponding retraction arm; and the three hinge joints are positioned on the same horizontal plane. When the hovercar runs on the ground, the principle of the hovercar is the same as that of a traditional automobile. When the hovercar needs to fly, the retraction jacks are opened, the rotating speeds of the four rotor wing devices are controlled respectively, and vertical take-off, forward flying, left and right off-course and the like can be realized.
Description
Technical field
The utility model relates to a kind of vertical take-off and landing flying car, belongs to the Flight Vehicle Design technical field.
Background technology
In recent years, along with modern society's rapid economy development, the big and medium-sized cities private car increases in a large number, and traffic pressure increases day by day, and traffic jam frequently takes place, and has caused a series of energy problem, environmental problem etc.The traffic problems that how effectively to solve the modern city existence become a great problem.In conjunction with the notion of the hovercar of enjoying the Li Fute proposition, the someone proposes to rely on this hovercar to alleviate the idea of traffic pressure, makes hovercar become the focus that the countries in the world relevant industries are competitively studied.
External associated companies and fan explore the automobile that can fly, and have proposed multi-form concept design, but it's a pity, there is not weak point in none.Mo Le professor [Wei Yan. the aerial automobile of High Performance. today section garden, 2009, (15): 39.] the MX-400 hovercar of development; Have four duct rotors, rotating speed and direction through controlling four ducts simultaneously provide lift and onward impulse; But structure is too heavy, handles complicated.The hovercar " Transition " that the U.S. " Terrafugia " company produces [being prone to rope. the hovercar of first in the world folding wing makes a successful trial flight. dual-use technology and product; 2009; (04): 11.], is exactly a folding fixed wing aircraft of wing in fact.Wing-folding draws in both sides when ground run, launches when needing flight.The fatal shortcoming that this type fixed wing aircraft exists is exactly that the landing of taking off needs the long runway of hundreds of rice, is not suitable for the landing of in the city, taking off fully.A hovercar of Israel's scientist's design-calculated [Deng Ran. the Israelis develops the automobile that can fly. Liberation Daily, 2007-02-02.] have two ducted fans that place interior of body, can VTOL as helicopter.But, be difficult to it is laterally handled, so lateral stability is relatively poor owing to only place two fans of front and back.
The utility model content
Existing hovercar takeoff distance is far away in order to overcome, the deficiency of poor stability, and the utility model provides a kind of vertical take-off and landing flying car, and this hovercar can be at ground run; Can the rotor device be opened when needing; Realization is taken off vertically, and has reduced operating difficulty, improves stability.
A kind of vertical take-off and landing flying car; It is characterized in that: comprise the ground run system, the ground run system comprises vehicle body, wheel, and rectangular layout type is equipped with four groups of jacks around the above-mentioned vehicle body; Two groups preceding; Two groups after, every group of jack formed by folding and unfolding arm and hydraulic efficiency gear, wherein an end of folding and unfolding arm is equipped with the rotor device other end and is articulated on the vehicle body; Hydraulic efficiency gear one end also is articulated in vehicle body and the other end is articulated in folding and unfolding arm stage casing, and above-mentioned three hinge-points are positioned on the same horizontal surface.
The running method of described vertical take-off and landing flying car is characterized in that: during ground run, jack is received in the vehicle body both sides with the rotor device; When going, jack opens to certain angle launches the rotor device; The airflight mode is specific as follows: in four groups of rotor devices, two groups of group rotor device hand of rotation on diagonal line are identical, and opposite with rotor device hand of rotation on another diagonal line; Take off: four groups of rotor devices produce identical lift, and when making a concerted effort greater than gravity, vehicle body steadily takes off vertically; Before fly: make at the rotating speed of two groups of preceding rotor devices rotating speed, produce a moment, make the headstock reduction less than the two groups of rotor devices in back; After the vehicle body rotation reaches certain angle, make the rotating speed that equals the two groups of rotor devices in back at the rotating speed of two groups of preceding rotor devices, promptly four groups of rotor devices produce onesize lift; Four groups of lift with vertical direction certain drift angle is arranged with joint efforts; The vertical component of should making a concerted effort is kept integral body and is aloft flown, and horizontal component then provides the power that advances, and realizes flight forward; Driftage: under the unmodified situation of making a concerted effort of the lift that keeps four groups of rotor devices to produce, make two groups of rotor device rotary speeds on the diagonal line, realize that headstock goes off course to the left or to the right less than two groups of rotor device rotary speeds on another diagonal line.
The utility model adopts the rotor device of rectangular layout, can easily realize taking off vertically, and horizontal, fore-and-aft stability when the while is effectively improved the flight of vehicle body integral body strengthen controllability.
The hovercar of the utility model is when ground run, and jack is received in the vehicle body both sides with the rotor device; When needing flight, jack opens to certain angle launches the rotor device.Adopt this mode can make automobile when ground run, take very little space, volume and traditional roadlice are very nearly the same.
In four groups of rotor devices, two groups of group rotor device hand of rotation on diagonal line are identical, and opposite with rotor device hand of rotation on another diagonal line.Adopt this measure can offset the reactive torque effect that four groups of rotor devices bring owing to high speed revolution, strengthen the stable of heading.
