Abstract

The utility model discloses a rotor with adjustable-pitch wing panel, relating to a rotor of an oar type vehicle. The rotor with adjustable-pitch wing panel comprises a wing panel 1, a wing rob 2, a wing cover 3, a movable cavity 4, a wing 5, a control lever 6, a gear 7 and a strip shape rack 8. An outer end of the wing rob 2 is connected with the wing panel 1 to an integral, a mid section of the wing rob 2 is fixed on edge of the wing 5 through the wing cover 3, and an inner end of the wing rob 2 is inserted into the movable cavity 4 and provided with the gear 7. A center of the wing 5 is the movable cavity 4, the control lever 6 and the gear 7 are both arranged in the movable cavity 4, and the strip shape rack 8 on the control lever 6 is engaged with the gear 7. The rotor with adjustable-pitch wing panel of the utility model not only starts an engine conveniently and controls speed of a vehicle without changing direction of rotation effectively, but also reduces sliding running distance during an aerial vehicle lands and increases emergency ability of the oar type vehicle.

Description

A kind of rotor of fin tilt adjustable

Technical field

The utility model relates to a kind of rotor that the slurry formula vehicle are arranged; Relate in particular to a kind of rotor of fin tilt adjustable, this rotor can be controlled the acceleration or the deceleration of the slurry formula vehicle effectively.

Background technology

Traditional rotor kind that the slurry formula vehicle are arranged is a lot, and shape is varied especially.Its structure is that the inclination angle between fin and wing body is changeless, and therefore various rotors can only make the slurry formula vehicle obtain enough lift or pulling force, its function singleness, and the impassabitity rotor is controlled the acceleration or the deceleration of the slurry formula vehicle effectively.In the space flight seafaring, speed no longer is unique pursuit, and the maneuverability of the slurry formula vehicle no less important that seems is arranged, and therefore traditional rotor can not satisfy the needs that there is the development of the slurry formula vehicle in the modern times far away.

Summary of the invention

The purpose of this utility model just is to overcome the shortcoming and defect that prior art exists, and a kind of rotor of fin tilt adjustable is provided.

The purpose of this utility model is achieved in that

As Fig. 1, Fig. 2, the utility model is made up of fin 1, wing bar 2, wing lid 3, movable chamber 4, wing body 5, joystick 6, gear 7, bar shaped tooth 8.

The outer end of wing bar 2 and fin 1 are connected as a single entity, and the stage casing of wing bar 2 is fixed on the edge of wing body 5 by wing lid 3, and the inner of wing bar 2 extend in the movable chamber 4 and is provided with gear 7;

At the center of wing body 5 is movable chamber 4, and joystick 6 and gear 7 all place in the movable chamber 4, bar shaped tooth 8 on the joystick 6 and gear 7 engagements.

Principle of work of the present utility model is:

In movable chamber 4, bar shaped tooth 8 on joystick 6 and the joystick 6 is connected with a joggle with the gear 7 that is fixed on wing bar 2 the inners, and the joystick 6 in the movable chamber 4 is with 5 rotations of wing body and can do front and back or plug formula crank motion together with the bar shaped tooth 8 on it in wing body 5.The outer end of wing bar 2 is connected with fin 1, and fin 1 inclination angle is unfixing and adjustable within the specific limits when work.

Suppose that the direction that has the slurry formula vehicle to advance is a positive dirction, fin 1 vertical orthogonal projection plane becomes 90 degree to be zero energy output state (not horsepower output) with working direction.During the work of driven by engine rotor, fin 1 inclination angle is adjusted into 90 degree under the effect of joystick 6, and this moment, engine was unloaded, was convenient to start; Treat with joystick 6 fin 1 progressive positive dirction inclination angle to be increased within the specific limits again after the driving engine normal operation, had the slurry formula vehicle that enough lift or pulling force are provided.When need of work or emergency situation, with joystick 6 fin 1 inclination angle is increased within the specific limits to negative direction, thereby make original lift or pulling force become resistance, thereby reach the purpose of deceleration.

The piston type motion of joystick 6 in movable chamber 4 can be done the dead axle rotation within the specific limits together with wing bar 2 and fin 1 by driven wheel 7, thereby reach the purpose at control break inclination angle.

Working process:

Negative angle 90 degree are zero energy output state (not horsepower output)

Positive angle.

The beneficial effects of the utility model are:

Be convenient to engine start, do not changing effective speed that the slurry formula vehicle are arranged of controlling under the condition that turns to, the ground run distance when shortening aircraft lands improves the emergency capability that the slurry formula vehicle are arranged.
