Problems solved by technology

[0003] 1. Limited capacity: Since the fuel tank is installed in the fuselage, limited by the size of the fuselage, the volume of the fuel tank is limited and cannot meet the requirements of long-distance battery life;
[0004] 2. The installation location is inconsistent with the installation location of the airborne equipment: because the fuel tank must be installed on the center of gravity of the fuselage, the traditional fuel tank will occupy the best position in the middle of the fuselage, resulting in a very low utilization rate of the fuselage space, and many equipment cannot be installed and cannot meet the requirements Increased demand for drone capabilities

Abstract

The invention relates to a gravity type split oil tank for a small unmanned aerial vehicle. The gravity type split oil tank comprises a consumption oil tank communicating with an unmanned aerial vehicle engine and two main oil tanks on the upper sides of the two sides of the consumption oil tank. Main oil tank oil outlets of the main oil tanks communicate with a consumption oil tank oil inlet of the consumption oil tank through first connecting pipes. The oil tank is placed in an aerofoil, the capacity is not limited any more, and the volume can be increased; the main oil tanks of the oil tankare installed on the two sides of a fuselage, the consumption oil tank is small in volume and does not occupy too much space of the fuselage, and a load device can be freely installed in the middle section of the whole fuselage.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle fuel tank devices, in particular to a gravity split fuel tank for small unmanned aerial vehicles. Background technique [0002] At present, the UAV industry mostly uses structural fuel tanks or hard-shell fuel tanks, most of which are installed on the center of gravity in the middle of the fuselage. However, due to the small size of most UAVs, their carrying space is limited, and the subsequent mailboxes have the following disadvantages : [0003] 1. Limited capacity: Since the fuel tank is installed in the fuselage, limited by the size of the fuselage, the volume of the fuel tank is limited and cannot meet the requirements of long-distance battery life; [0004] 2. The installation location is inconsistent with the installation location of the airborne equipment: because the fuel tank must be installed on the center of gravity of the fuselage, the traditional fuel tank will occupy the best...
