Description

A kind of tiltrotor aircraft based on four rotors and fixed-wing compound
Technical field
The present invention relates to airplane design technology, be specially a kind of tiltrotor aircraft based on four rotors and fixed-wing compound.
Background technology
Taking off and landing and be subject to the restriction in place all to a great extent due to Fixed Wing AirVehicle, often need specific runway for taking off and landing, and it can not hover aloft, not perform some specific aerial missions.
All can not there is verting forward or backward in tradition quadrotor four rotors, on the one hand, when it flies and does before realizing level, require that two gyroplane rotate speeds being in front fuselage reduce, and be in back body two gyroplane rotate speeds increases, produce lift difference because front and back end gyroplane rotate speed is different like this, and then inevitably cause fuselage to produce luffing, fly before making aircraft level to influence each other with vertical lifting; On the other hand, traditional quadrotor limits due to its Design Mechanism, is difficult to reach cruising speed higher as fixed wing.
Tiltrotor aircraft has the advantage of cyclogyro and fixed wing aircraft simultaneously, when vertical takeoff and landing, provides to raising force by rotor, when cruising flight, provides lift by the fixed wing being fixed on fuselage.Existing tiltrotor aircraft mostly is diaxon and verts, as the MV-22 of the U.S., more unstable during very limited and two rotary-wing flight of the load carrying ability of aircraft when the shortcoming of this type of tiltrotor is vertical takeoff and landing.Meanwhile, existing tiltrotor is verted complicated in mechanical structure and process of verting is dangerous.Exactly because above-mentioned shortcoming makes the application of tiltrotor aircraft be extremely restricted.

The present invention is achieved through the following technical solutions: a kind of tiltrotor aircraft based on four rotors and fixed-wing compound, comprises four motors, transmission shaft is verted in fuselage, outside, both sides swept wing, wingtip, vertical tail, the horizontal wing in stage casing, fuselage interior are verted transmission shaft, transmission gear, aileron and tailplane, it is characterized in that: nosing is verted by outside, and transmission shaft is symmetrical installs the first motor and the second motor, middle fuselage is by the horizontal wing in erection of main beam stage casing, back body is verted by outside, and transmission shaft is symmetrical installs the 3rd motor and the 4th motor, fuselage interior is longitudinally installed fuselage interior and to be verted transmission shaft and transmission gear, the described outside transmission shaft that verts is linked together by two transmission gears and the fuselage interior transmission shaft that verts, back body installs tailplane and vertical tail, swept wing is installed with the sweepback angle of 50 ° symmetry respectively in horizontal wing both sides, stage casing, both sides swept wing installs aileron respectively, both sides swept wing end installs wingtip.
First, second, third, fourth electric motor mounting structure of the present invention is the same; Described first, second, third, fourth parameter of electric machine is the same, and adjacent direction of motor rotation is contrary between two.
First motor of the present invention, the second motor, the 3rd motor, the 4th motor by two outsides vert transmission shaft respectively symmetry be arranged on fuselage both sides, a set of rotor respectively installed by first, second, third, fourth motor.
Of the present inventionly control fuselage interior by reclining device and to vert drive axis thus drive the outside transmission shaft that verts that the first motor, the second motor, the 3rd motor, the 4th motor in synchrony are verted; Front and back group of motors shares a set of structure of verting, and realizes synchronously verting.
Four rotors of the present invention and fixed-wing share a set of engine installation, are four rotor mode when vertical takeoff and landing or hovering, control aircraft with four rotor flying control system; When switching to fixed-wing pattern, control aircraft with fixed-wing flight control system.
When aircraft switches to fixed-wing mode process by four rotors, it is 0 ° to 45 ° that first, second, third, fourth motor synchronously tilts forward angle by control system of verting with the drive mechanism that verts, and is still now four rotor master modes; When first, second, third, fourth motor in synchrony tilts forward angle when being greater than 45 °, Automatic control of single chip microcomputer switches to fixed-wing master mode, two groups of motors vert to level attitude to preamble immediately, then controlling aircraft flight attitude in fixed-wing mode, is now fixed-wing master mode.
When aircraft is four rotor mode, controlled the flight attitude of aircraft by the differential controlling first, second, third, fourth motor; And when aircraft is fixed-wing pattern, controlled the flight attitude of aircraft by level of control empennage, vertical tail, aileron.
When receiver receives control signal, microcomputer control system produces four rotors and fixed-wing tilt control signal automatically according to instruction, drives the steering wheel system of verting that first, second, third, fourth motor is verted.
Advantage of the present invention is: make four rotors and fixed-wing share a set of power system and realize vertical takeoff and landing, hovering and cruising level flight, anteversion and retroversion rotating motor group (1,2) (3,4) share a set of reclining device and realize synchronously verting by the transmission shaft that verts, and simplify vert structure and improve road-holding property and the stability of tiltrotor with this.
