Abstract
The utility model provides a better unmanned helicopter of function of hovering, includes the fuselage, main shaft, screw and the device that hovers. The main shaft is fixed in the upper end of fuselage, and the screw is fixed on the main shaft with the device that hovers. The upper end of device setting at the screw of hovering. The device that hovers constitute by two sections the same circular arcs, the 0.3 -0.4 that the radius R of circular arc is single screw length is doubly. This kind of installation device that hovers on unmanned helicopter, it is more stable not only can to guarantee to hover, and the screw only needs less rotational speed just can maintain to hover moreover.
Description
Technical field
The utility model relates to a kind of depopulated helicopter, and especially the better depopulated helicopter of a kind of hovering function, belongs to unmanned air vehicle technique field.
Background technology
The structure of depopulated helicopter is fairly simple, price is also cheaper, and do not need emission coefficient, can also vertical takeoff and landing, more can freely hover, the flight alerting ability that gets up is quite superb, available various speed, flies with the air route of various flight profile, mission profile, is therefore applied in military affairs, the every field such as civilian widely.Hovering function is the very important function of depopulated helicopter, but current depopulated helicopter is due to the restriction of structure, and when hovering, stability is not very high, and consumes a large amount of energy when hovering.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides the better depopulated helicopter of a kind of hovering function.
For achieving the above object, the technical solution adopted in the utility model is: the better depopulated helicopter of a kind of hovering function, comprises fuselage, main shaft, screw propeller and suspension device.Main shaft is fixed on the upper end of fuselage, and screw propeller and suspension device are fixed on main shaft.Suspension device is arranged on the upper end of screw propeller.Described suspension device is made up of two sections of identical circular arcs, the radius R of circular arc be the 0.3-0.4 of single screw propeller length doubly.
Depopulated helicopter is installed this suspension device, not only can ensure that hovering is more stable, and screw propeller only needs less rotating speed just can maintain hovering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1: the better depopulated helicopter of a kind of hovering function, comprises fuselage 1, main shaft 2, screw propeller 3 and suspension device 4.Main shaft 2 is fixed on the upper end of fuselage 1, and screw propeller 3 and suspension device 4 are fixed on main shaft.Suspension device 4 is arranged on the upper end of screw propeller 3.Described suspension device 4 is made up of two sections of identical circular arcs, and the radius R of circular arc is 0.3 times of single screw propeller length L.
During work, main shaft High Rotation Speed, carrying screws and suspension device rotate, and suspension device can bring certain raising force, thus under lower rotating speed, also can ensure the stability of hovering.
