Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.It should be appreciated that described herein
Specific embodiment is only used to explain the present invention, is not intended to limit the present invention protection content.
Power plant module provided in this embodiment can before the unmanned vehicle that exchanges of drawing/pusher specifically include that modularization body
(including leading portion 1, middle section 2, back segment 3), wing 4, empennage 5, aileron 6, propeller 8.
Modularization body quick release be before, during and after three parts, by bolt 9 (such as Fig. 3 institute between adjacent fuselage section
Show) it is attached.When unmanned vehicle is to meet specific task needs, when using preceding drawing mode flight, such as Fig. 1, Fig. 3 institute
Show, modularization body leading portion 1 is engine embedded in body leading portion then for installing dynamical system, uses at propeller hub
Conformal paddle cover is to maintain the aerodynamic configuration of full machine.Modularization body middle section 2 and modularization body back segment 3 are for installing airborne electricity
Sub- equipment, fuel tank and mission payload etc..When unmanned vehicle is to meet particular task to need using the flight of pusher mode, such as scheme
2, shown in Fig. 4, modular power system is installed on modularization body back segment 3, equally, engine embedded in body back segment, tail
The aerodynamic configuration for using conformal paddle cover to maintain full machine at propeller hub is pushed away, modularization body leading portion 1 and middle section 2 are then used for
Airborne equipment, mission payload etc. are installed.
Optionally, the cross section of modularization body is using circle, this makes under identical body volume, circular cross section machine
Body has the smallest surface area, and then keeps the frictional resistance of body minimum.If being limited and cannot be used by certain specific conditions
When circular cross section, also can choose other cross-sectional shapes, the present embodiment not to modularization body (including leading portion 1, in
Section 2, back segment 3) cross-sectional shape be defined.
Optionally, carbon fibre material can be used in three sections of fuselage skins before, during and after modularization body, holds in enhancing fuselage
Whole machine weight is effectively reduced while loading capability.The structural framing of modularization body is mainly by aluminum frame, aluminum reinforcing frame, aluminum
Stringer composition；Body middle section 2 is equipped with the devices such as navigation/flight control system, mission payload, power supply, body leading portion 1 and body back segment
3 can need correspondingly to install propeller, engine and mission payload or airborne equipment etc. according to task.
For wing 4 for providing lift during flat fly for unmanned vehicle, geometry can be the straight wing, tapered airfoil
Equal geometric shapes, the present embodiment are not defined the geometric shape of wing 4.
Optionally, empennage 5 can be tailplane, vee tail or other forms.Vee tail is provided simultaneously with vertical end
The function of the wing and tailplane, and generated interference drag is lower, and the present embodiment does not carry out the arrangement of empennage 5
It limits.
