Description
Technical field
The invention belongs to the technical field of Flight Vehicle Design, more specifically, the present invention relates to a kind of can rapid vertical landing can the technical field of helicopter of high-speed horizontal flight.
Background technology
The helicopter at home and abroad used at present generally has two kinds, the first: it is directly over fuselage, to set a parallel king bolt oar be responsible for aircraft rising and flight forward, after fuselage, sets the minor spiral oar of the responsible control aircraft left and right heading of a lateral rotation simultaneously；The second be above helicopter before set a propeller, after set a propeller, the weak point of both aircrafts is the most sufficiently to utilize floating force and the support force of air, so flight speed is slow, fuel consumption is big.And the military upper helicopter used do not require nothing more than helicopter can rapid vertical landing, and require also to be able to keep certain speed when horizontal flight.Generally the distribution engine of helicopter is by transversely arranged for multiple electromotors, and this can expand the overall front face area of aircraft, and resistance increases；If one side power failure, also will adversely affect the balance of helicopter in addition.
In prior art, Do335 arrow formula fighter plane is a kind of " pulling in front and others push behind " driving aircraft, it is characterized in two electromotors to be longitudinally arranged on body axis, while aircraft keeps the overall front face area that monomotor is less, possesses again bimotored strong impetus.Its maneuvering performance, mobility, especially acceleration and gyroscopic characteristics is all the most outstanding, owing to Do335 is fixed wing airplane, need longer takeoff and landing airstrips, do not possesses the ability of VTOL or STOL, again because the end of World War II and the appearance of jet plane, early have dropped out the arena of history of aircraft.
For increasing power performance and the transport capacity of helicopter, column dual rotors layout helicopter CH-46 sea knight's transport helicopter arises at the historic moment, and is characterized in before and after helicopter being respectively arranged with a rotor system, thus strengthens transport capacity, and strong adaptability.Can fly under relatively harsh weather, naval then transports to equipment on warship with this helicopter or performs search and rescue aid task.CH-46 is the double oar of tandem, can be with VTOL or STOL, hovering, flexibly and easily, battlefield survival and transport capacity are strong, because its voyage is limited, type waits for a long time very much other shortcoming, on August 1st, 2015, Medium Helicopter squadron of U. S. Marine Corps 774 carries out last farewell flight, and CH46 retires from active service from USN from this, is gradually replaced by osprey V-22 series.
V-22 " osprey " tilt rotor aircraft of the existing U.S., is characterized in that electromotor and propeller blade are symmetrically mounted on the tip of aircraft both sides wing, it is possible to rotate around wing, thus realizes vertical lift and horizontal flight.By contrast, tilt rotor aircraft have concurrently conventional helicopters and with propeller (rotor) drive into the advantage of fixed wing airplane, superior performance.But, tilt rotor aircraft has born major defect, the electromotor of tilt rotor aircraft is placed in the wing tip of fixed-wing, fixed-wing is made to become the cantilever that stress is severe, this is the major reason causing stable hidden danger, and meanwhile, this propeller blade is symmetrically mounted on aircraft both sides, the gravity and the gravitation point that form tilting rotor are arranged vertically with fuselage, will also result in vertical lift and the horizontal flight of aircraft from amechanical angle and run many technological deficiencies and the potential safety hazards such as safety.
In above-mentioned three kinds of aircraft of prior art, the electronic degree of V-22 " osprey " is the highest, once breaks down and cannot save, and safety coefficient is relatively low, and when one group of propeller blade damages, aircraft cannot be avoided crash accident, there is the problems such as civil nature difficulty is bigger.Accordingly, it would be desirable to carry out upgrading on the basis of existing helicopter, overcome existing problem and shortage.
