Between fuselage lower plate.
As a further solution of the present invention: four bolts on the outer surface of the duct connection female cylindrical hole
After locking, since there are "-" type opening in the cylindrical hole two sides of duct connection female, the coupling mechanism force of bolt can make duct connect female
Cylindrical hole very small deformation occurs, which enables to the cylindrical hole of duct connection female duct can be connected male connector
Cylindrical end clamp.
As a further solution of the present invention, the upper duct support ring be fixedly mounted on duct connection female and
Between fuselage upper plate, the lower duct support ring is fixedly mounted between duct connection female and fuselage lower plate.
Compared with prior art, the utility model has the beneficial effects that
1, inclined angle alpha can be adjusted by mutual disassembly's bolt in the utility model, allow the inclined angle alpha root
It is continuously adjusted according to actual needs, so that duct deflects a low-angle, carries out course control using the component of duct thrust
System；
2, due to the presence of inclined angle alpha in the utility model, when so that unmanned plane needing to yaw, the thrust energy of ducted fan
A part of steering torque is provided, unmanned plane Heading control efficiency is greatly improved.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of adjustable duct obliquity structure of ducted fan unmanned plane,
Including ducted fan 1, duct connection male connector 2, duct connection female 3, bolt 4, upper duct support ring 5, lower duct support ring 6,
Fuselage upper plate 7 and fuselage lower plate 8；The outer surface of the ducted fan 1 connects 2 one end of male connector integrally formed with square hole, duct
For square end, it is round nose that duct, which connects 2 other end of male connector, and the square end of duct connection male connector 2 is fixedly mounted on ducted fan 1
