Description

A kind of jet-propelled type helicopter with rotating wings

Technical field

The utility model belongs to the unmanned plane technical field, relates to rotor craft, especially a kind of jet-propelled type helicopter with rotating wings.

Background technology

at present, it is to provide power by built-in motor that the unmanned plane helicopter produces power, engine type commonly used has fuel engines, cylinder piston type driving engine or turbo type engine, driving engine is individual offers a vertical parallel shaft with rotary power, screw propeller that connects six monomers of the mouth of this vertical parallel shaft, the propeller blade of these six monomers is horizontally rotated, like this, propeller blade cuts its upper stationary air, still air after cut has just produced an air stream that flows downward, air stream produces lift upwards to screw propeller simultaneously, under the effect of such application force and antagonistic force, helicopter is gone up in the air.

Cyclogyro just refers to that its lift is all or part of and is had by one (or a plurality of) that the major diameter screw propeller of vertical axis provides, this screw propeller is called " rotor " or " rotor blade ", its onward impulse is to be provided by engine-driven advancing blade, and cyclogyro needs sliding race of certain distance to accelerate when taking off.Specifically, cyclogyro is actually a kind of aircraft between helicopter and fixed wing aircraft, remove outside rotor, also with a secondary vertical propelling screws of placing so that the power that advances to be provided, generally less wing also is housed provides part lift awing.The maximum difference of cyclogyro and pure helicopter is, the rotor of cyclogyro is not connected with engine driving system, driving engine is not to drive rotor to provide lift for aircraft, but in cyclogyro advances process, blow rotor wing rotation by air-flow and produce lift, usually rotor system is only driven by self power when starting, is referred to as to prewhirl, and drives by air effect power after taking off; And the rotor of helicopter is connected with engine driving system, can produce lift, and the power of flight can be provided again.Because rotor is rotation type, the moment of torsion that is delivered on fuselage is very little, so cyclogyro need not the such tail-rotor of single-rotor helicopter, but empennage generally is housed, in order to control flight.

Present depopulated helicopter power drive system more complicated drives main rotor by driving engine by change speed gear box, also will drive the empennage that sticks up on tail at the rear by the transmission device of very long complexity and move, and complicated dynamic structure extremely makes people's headache like this.In addition, the rotor on the power system of helicopter is also easily accidents caused, and tail-rotor is very easy in the process that the low latitude turns to and the objects such as treetop, high tension cord bump against, and tail-rotor will be once fracture will cause the comparatively serious aircraft accident of helicopter grade out of control to occur.
