Description
Technical field
The utility model relates to a kind of aircraft devices, particularly relates to the double-rotor aerobat that a kind of lower blade can fold and overhang.
Background technology
It is simple that unmanned vehicle has structure, flight stability and be easy to manipulate feature, at present no matter in life or in scientific investigation, all have in civil and military and apply more and more widely, in the middle of these unmanned vehicles, there is a kind of unmanned vehicle of DCB Specimen, namely two rotor motors are set coaxially on a rotor arm and respectively rotor blade are installed, so just can start separately the rotor motor on top or the rotor motor of bottom, so just there is the redundancy of power, if the motor et out of order on top, the rotor motor on top can be closed and only open the redundancy motor of bottom, the situation that would not aircraft be caused out of control because of fault like this, the unmanned vehicle of these current DCB Specimen, because the blade of the rotor motor corresponding up and down on same rotor arm is all be in the state of opening always, therefore the motor above rotor arm when High Rotation Speed because downward air-flow can be produced, therefore the blade below rotor arm can produce the turbulent phenomenon of air under the effect of telling air-flow, be unfavorable for the stabilized flight of aircraft, when the resistance of the lower rotor motor had is less, the blade of lower rotor also can and then rotate under the effect of air-flow, cause the loss in vain of unmanned plane energy.
Utility model content
The utility model is to solve above-mentioned technical matters, provides the unmanned plane that a kind of lower blade can overhang with hiding.
The utility model adopts following technical scheme: the collapsible double-rotor aerobat overhang of this lower blade, comprise aircraft body, the rotor arm be fixedly connected with aircraft body, the upper rotor motor of coaxial setting on each rotor arm and lower rotor motor, described upper rotor motor and the motor shaft of lower rotor motor are respectively equipped with blade and lower blade, the motor shaft that lower blade set on described lower rotor motor folds by fold-down blade installation structure and the lower rotor motor overhang fixedly mounts, described fold-down folds the blade installation structure overhang, include the blade seat of annular steps shape, be located at the blade seat hinge axis hole along the distribution of step surface tangential direction on the interior step of blade seat and hinge, described lower blade and blade seat are fixed one end and are provided with corresponding vane hinge portion, this vane hinge portion is provided with corresponding vane hinge hole, this hinge hole is hinged by hinge and blade seat hinge axis hole, and the horizontal surface between the interior step of the upper side in vane hinge portion and blade seat hinge axis hole and outer step mutually extrudes and contacts.
In the collapsible double-rotor aerobat overhang of lower blade of the present utility model, the material of described lower blade is metal material.
In the collapsible double-rotor aerobat overhang of lower blade of the present utility model, the vertical plane between the interior step of described lower blade and blade seat hinge axis hole and outer step mutually extrudes the position contacted and is provided with bump rubber for cushioning.
In the collapsible double-rotor aerobat overhang of lower blade of the present utility model, the diameter of described lower blade is identical with the diameter of blade.
In the collapsible double-rotor aerobat overhang of lower blade of the present utility model, the material of described lower blade is plastic cement material.
Useful effect: owing to adopting above-mentioned technical scheme, the collapsible double-rotor aerobat overhang of lower blade of the present utility model, rotor machine operation on unmanned vehicle, when lower rotor motor does not work, on the lower rotor motor of unmanned vehicle with blade can be automatically downwards folding, turbulent flow is produced in the air-flow of the downward effect that can not produce at blade, be conducive to the stable of unmanned vehicle state of flight, when needs lower blade works, lower blade drives at lower rotor motor under the effect of the centnifugal force produced can Automatic-expanding working.
