Problems solved by technology

[0002] Helicopters are widely used in environmental surveys, scientific research experiments, pesticide spraying, forest fire protection and other fields. At present, helicopters are basically powered by engines, and the endurance time is one of the important indicators to measure the performance of the helicopter. However, due to the small size of the helicopter and the streamlined surface design of the fuselage , complex internal structure and other reasons, the capacity of the fuel tank is small, and it is difficult to guarantee the battery life

Abstract

The invention discloses a helicopter fuel tank assembly and a helicopter. The helicopter fuel tank assembly comprises an external fuel tank and an internal fuel tank, and an inner cavity of the external fuel tank is communicated with an inner cavity of the internal fuel tank; the external fuel tank comprises a left fuel tank body and a right fuel tank body; the internal fuel tank is located between the left fuel tank body and the right fuel tank body. The helicopter fuel tank assembly can cooperate with the integrated arrangement of a helicopter body, the space of the helicopter body is fullyutilized, the external fuel tank is added, the fuel load of an fuel tank system is increased, and the time of endurance is prolonged.

Description

technical field [0001] The invention relates to the technical field of aviation aircraft and mechanical design, in particular to a helicopter fuel tank assembly and a helicopter. Background technique [0002] Helicopters are widely used in environmental surveys, scientific research experiments, pesticide spraying, forest fire protection and other fields. At present, helicopters are basically powered by engines, and the endurance time is one of the important indicators to measure the performance of the helicopter. However, due to the small size of the helicopter and the streamlined surface design of the fuselage , complex internal structure and other reasons, the capacity of the fuel tank is small, and it is difficult to guarantee the battery life. [0003] Therefore, in order to solve the above problems, a kind of helicopter fuel tank assembly is needed, which can cooperate with the overall layout of the body, make full use of the body space, add an external fuel tank, impro...
