Description
Technical field
The utility model belongs to rotor craft technical field, is to be related to a kind of rotor control device more specifically.
Background technique
Miniature rotor craft is chiefly used in consumer level individual and takes photo by plane in recent years, and small-sized rotor craft is chiefly used in agricultural pesticide
Sprinkling, police and military scouting, this kind of aircraft majority use more rotor aerodynamic arrangements, and minority (is commonly gone straight up to using single rotor
Machine) or DCB Specimen (coaxial double-oar aircraft) aerodynamic arrangement.
It is capable of the common aerodynamic arrangement's scheme of rotor craft of hovering flight at present there are three types of scheme, the first: more rotations
Wing scheme, this mode at least need the propeller of 3 or 3 or more independent controls.The program is by controlling each spiral shell
The revolving speed of paddle is revolved to control the posture of aircraft；Second: single rotor (pure helicopter) scheme, including a main rotor and one
A empennage for being used to offset main rotor torque.The program drives the pitch of main rotor to fill by being more than or equal to 2 Servo-controllers
It sets to control the posture of aircraft；The third: there are coaxial cloth up and down in DCB Specimen (coaxial double-oar aircraft) scheme, the aerodynamic arrangement
Two propellers set.Up and down by the pitch or lower layer's pitch at least two Servo-controller driving upper layer or driving simultaneously
Two layers of inclination disc mechanism controls the flight attitude of aircraft.
Above-mentioned three kinds of schemes are respectively provided with following disadvantage:
The first, the shortcomings that more rotor schemes, is, due to replacing one with multiple small propellers under comparable size rank
Big rotor, therefore its pneumatic efficiency is lower, this directly results in the continuous of the multi-rotor aerocraft of same order or power configuration
ETS estimated time of sailing is not so good as traditional helicopter, and thus further bring is the disadvantage is that small propeller needs ability higher than big rotor revolving speed
Same lift can be reached, revolving speed is higher, and to represent noise bigger.Also, this aircraft is by continually adjusting each propeller
Revolving speed control the posture of aircraft, motor driven propeller frequently accelerates or brakes to result in the waste of energy.Separately
Outside when this kind of aircraft size increase when, if you need to it is manned situations such as, the inertia of propeller is excessive, and it is fast to be unfavorable for direct driving motor
The revolving speed of the adjustment propeller of speed, this causes the controllability of aircraft and flight stability to substantially reduce.
Second: the shortcomings that single rotor scheme is that there are two propellers for program tool, one of them is main rotor, another
A is tail rotor, and the rotary shaft of tail rotor is vertical with main rotor, and tail rotor offsets main rotation by changing revolving speed or changing pitch

Compare and is difficult to repair；In addition it tilts dish structure and servo motor occupies the biggish space of fuselage, while also increasing weight.Tail
The support rod of propeller can be exposed under the downwash flow of propeller, this is but also its lift for having lost a part.
The third: there are two main screw, the coaxial rotation of two propellers and direction of rotation phases for coaxial double-oar flying instrument
Instead.This coaxial double-oar aircraft is equipped with inclination dish structure below propeller, which is controlled by servomechanism installation, leads to
The pitch of the control of the pitch structural periodicity one or two propeller is crossed to realize to aircraft pitching and roll two
The control of freedom degree controls the yaw of aircraft by adjusting the rotational speed difference of two propellers, by adjusting two propellers
Mean speed or pitch come control lift size so that control aircraft flying height.Although this aircraft has used altogether
The double paddles of axis simultaneously improve flight efficiency, but the pitching of aircraft and roll gesture stability are needed by least two servo motors
It is realized with inclination dish structure, Servo-controller often higher cost and include complicated gear deceleration group identical as second scheme,
It is unfavorable for being mass produced and reducing cost.Simultaneously this second and machine of the third aircraft relative to multi-rotor aerocraft complexity
Tool structure also brings inconvenience for aircraft daily maintenance.
For the control mode of above-mentioned various traditional rotor aircraft, multi-rotor aerocraft at least needs 3 motor ability
Realize the control to aircraft, and its cruise duration is short, noise is big and pneumatic efficiency is low；Single rotor and double-rotor aerobat are not only
