Description
Technical field
The utility model belongs to field of aviation flight, specifically a kind of scissor more particularly to manned autogyro
DCB Specimen seesaw type autogyro.
Background technique
Autogyro, English are referred to as Autogyro, are also often referred to as gyroplane Gyroplane, gyroplane
Rotorplane either rotor craft (Gyrocopter), it be one kind by autorotation and non-power driven ultrasonic is risen
The rotor class aircraft of power, it is general to provide onward impulse with a propelling screws, in this respect and Fixed Wing AirVehicle
It is similar.The shape of autogyro is similar with helicopter, but the rotor that must have air-flow that could drive it by its paddle disk
Rotation.The same with helicopter, autogyro drives the power resources of rotor rotational using rotor as main lift unit
It is different.
Autogyro needs to slide on the ground when taking off race, required pulling force or thrust from fore-body or rear portion
Propeller, by head-on blow it is rich drive rotor rotational, it is but clockwise unlike windmill, but reverse.When preceding winged, autorotating rotor
The paddle disk of machine retreats, and turns forward like that rather than helicopter.
Autogyro generallys use single rotor design at present, meets gyroplane if single rotor generates enough lift and takes off,
Biggish rotor radius is then needed, which not only adds the manufacture difficulty of rotor, and increase the size of gyroplane.Meanwhile
Single rotor high speed rotation generates bigger body vibration, influences the flight quality of gyroplane.In addition, coaxial double-rotary wing is laid out at present
In design, upper and lower two rotors angle is often 90 ° of plumbness, and design in this way can not obtain optimal pneumatic efficiency.
Utility model content
The utility model discloses a kind of scissor DCB Specimen seesaw type rotation aiming at the problems existing in the prior art
Gyroplane using scissor autorotating rotor and is all made of seesaw type propeller hub using the autogyro based on non-power driven ultrasonic,
The autogyro of the utility model is able to ascend the performance of existing autogyro, and structure is simple, space occupancy is small, safety
The novel autorotation gyroplane that coefficient is high, maneuvering performance is excellent, flying quality is good, cost performance is high.
The utility model is realized in this way:
A kind of scissor DCB Specimen seesaw type autogyro, including fuselage, which is characterized in that the fuselage upper end
Rotor system is set；Rotor system lower end is connected with the system of prewhirling；T-type empennage is set between fuselage and rotor system；Fuselage
Propulsion device is arranged in tail portion.The rotor system is rotation DCB Specimen, and is all made of seesaw type propeller hub, upper and lower seesaw
Pass through rotation axis connection between formula propeller hub.The system of prewhirling includes motor and gear set, and the motor, gear set are pacified
Loaded on rotation DCB Specimen lower end；Motor transmits torque to rotary shaft by gear set；It is prewhirled technology using rotor, i.e., it is sliding logical when running
It crosses transmission device and turns rotor in advance, then by taking off after unidirectional axial cutting transmission system, realize ultra-short takeoff.
The tail end of the T-type empennage is horizontal stabilizer and is installed on the vertical stable of horizontal stabilizer two sides
Face；The propulsion device is the propeller for being mounted on fuselage afterbody.Large area horizontal stabilizer and fixed fin improve and fly
Longitudinal direction, shipping-direction stability when row.
Further, the lower beam of the fuselage is provided with bikini undercarriage, the bikini undercarriage of setting, for certainly
Motion control of the switch rotor machine in ground transition.
Further, the rotation DCB Specimen is configured as U-shaped scissor autorotating rotor, take-off weight in 700kg or more,
Mission payload 180kg or more, autogyro of the practical ceiling in 1600m or more.
Further, the scissors angle of the autorotating rotor is 25 °.The angular range at scissors angle is 15 ° to 90 °, optimum angle
Degree is 25 °, and rotor has optimal aerodynamic effect when the state of the best angle, while can reduce the noise of rotor generation,
Weaken the aerodynamic interference between rotor and fuselage, autogyro is made to reach optimal efficiency.
Further, there is vertical fin rudder face on the fixed fin.There is vertical fin rudder face on fixed fin can
High efficiency manipulation is carried out with the course to autorotating rotor.
Further, the inside of the fuselage is also equipped with two engines, is started by being mounted on intracorporal two, machine
Machine carries out driving propeller simultaneously.
The beneficial effect of the utility model and the prior art is:
1) autogyro that the utility model uses be it is a kind of by autorotation and non-power driven ultrasonic obtains lift
Rotor class aircraft, autogyro provides onward impulse with a propelling screws, in steady flight, gyroplane
Rotor provides lift and pitching, roll attitude operating torque, different from helicopter, and the rotor of gyroplane relies on front incoming flow oblique
On blow over paddle disk and always in stablizing autorotation, once thus engine flame-out in flight, can still pacify by autorotation
It is complete to land, guarantee the flight quality of gyroplane；
2) using seesaw type propeller hub only pass through a level compared with autorotating rotor axis connection, this propeller hub structure eliminates
Lead lag hinge, damper, two panels blade share a set of flapping hinge, are suitable for autogyro；
3) scissor rotor is a kind of not contour formula rotating vane arrangement being made of upper and lower two metaplasms leaf, and two metaplasm leaves are total
With the same rotor shaft and there are certain angles, and configuration range used today is smaller, and it is straight to be more common in the arms of single rotor formula
The tail-rotor of the machine of liter；In the identical situation of disk loading, scissor DCB Specimen radius is much smaller than conventional single rotor, compares with tradition certainly
Turn DCB Specimen, scissor autorotating rotor tension coefficient proposed in this paper is greater than DCB Specimen, and scissor rotor is relative to routine
The rotor of configuration has certain noise reduction capability；Therefore, the utility model uses scissor DCB Specimen seesaw autorotating rotor
Machine has more preferably pneumatic efficiency, lower noise level and bigger payload than traditional autogyro.
