Small multipurpose unmanned aerial vehicle with oil tank embedded into blended wing body

Abstract

The invention relates to a V-tail unmanned aerial vehicle with an oil tank embedded into a blended wing body. The unmanned aerial vehicle can be used to execute flight missions such as scientific experiments, remote sensing, aerial photographing and the like. The unmanned aerial vehicle is characterized in that: 1) the duration of flight is long and flight missions with high requirements can be conducted conveniently; 2) the use is simple and the operation is convenient; 3) the stability is good and devices such as autopilots, aerial photographing cameras, video cameras and the like can be carried; and 4) the requirement on taking-off and landing conditions is low. According to one aspect of the invention, the small unmanned aerial vehicle comprises a body (1), wings (3), an empennage (7), a left front oil tank (16), a left rear oil tank (15), a right front oil tank (13) and a right rear oil tank (14), wherein the wings (3) are connected on the body (1); and the left front oil tank (16) is arranged at the left front of the internal part of the body (1), the left rear oil tank (15) is arranged at the left rear of the internal part of the body (1), the right front oil tank (13) is arranged at the right front of the internal part of the body (1) and the right rear oil tank (14) is arranged at the right rear of the internal part of the body (1). According to the further aspect of the invention, the left front oil tank, the right front oil tank, the left rear oil tank and the right rear oil tank are respectively provided with shapes adaptive to the wing profile of the body and balanced oil consumption sequences.

Description

technical field [0001] The invention relates to the design of a small multi-purpose unmanned aerial vehicle with a fuel tank embedded in a wing-body fusion body, which belongs to the field of structural design of aviation aircraft, in particular to the structural design of a small unmanned aerial vehicle that requires a relatively long endurance time. Background technique [0002] The cost of UAV is relatively low, it can avoid the casualties of drivers, and it can perform many tasks that man-machines cannot perform. It has broad application prospects. [0003] Existing UAVs mainly use a simple box-shaped fuselage and a conventional hexahedron-shaped fuel tank, which has high flight resistance, low utilization rate of internal space, small amount of fuel carried, and short voyage time. And most of them are tailor-made according to specific task loads, and the versatility of task load loading is not strong; it is not very convenient to carry out loading tests on loads that ha...

[0003] Existing UAVs mainly use a simple box-shaped fuselage and a conventional hexahedron-shaped fuel tank, which has high flight resistance, low utilization rate of internal space, small amount of fuel, and short voyage time.

And most of them are tailor-made according to specific task loads, and the versatility of task load loading is not strong; it is not very convenient to carry out loading tests on loads that have not been formally finalized, and sometimes even the body structure needs to be modified
