Small multipurpose unmanned plane with oil tank embedded into blended wing body

Abstract

The invention provides a V-shaped tail layout unmanned plane with an oil tank embedded into a blended wing body, which can be used for executing flight missions on scientific research experiment, remote sensing, aerial photography and the like. The unmanned plane has the following characteristics that 1, the flight duration is longer and the implementation of the flight commission with higher requirement on flight time is facilitated; 2, the use is simple and the control is facilitated; 3, the stability is better and the unmanned plane is applicable for carrying equipment such as an autopilot, an aerial camera and a vidicon; and 4, the take-off and landing conditions are lowly required. The small unmanned plane according to one aspect of the invention comprises a plane body (1), wings (3), a tail wing (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 onto the plane body (1); and the left front oil tank (16), the left rear oil tank (15), the right front oil tank (13) and the right rear oil tank (14) are arranged ahead of the left, behind the left, ahead of the right and behind the right in the plane body (1) respectively. According to a further aspect, the left front oil tank, the right front oil tank, the left rear oil tank and the right rear oil tank are in a shape matched with the wing type of the plane body, and have a balanced oil consumption sequence.

Description

[0001] This application is a divisional application of Chinese patent application No. 201010125833.2. technical field [0002] 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 [0003] 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. [0004] 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 o...

Problems solved by technology

[0004] Existing drones mainly use a simple box-shaped fuselage and a conventional hexahedron-shaped fuel tank, which has high flight resistance, low utilization of internal space, small amount of fuel, and short flight 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
