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 endurance time. When the external fuel tank is provided for auxiliary expansion of the helicopter, the external fuel tank has no support point and the installation is unstable.

Abstract

The invention discloses a short wing of a helicopter and the helicopter. The short wing of the helicopter comprises a short wing body and a short wing connecting frame, wherein one end of the short wing connecting frame is fixed on a helicopter body, and the other end is connected on the short wing body. The short wing of the helicopter can be fixed on the helicopter body to provide a mounting point for an external mounted fuel tank and assist flight of the helicopter.

Description

technical field [0001] The invention relates to the technical field of aviation aircraft and mechanical design, in particular to a helicopter short wing 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 endurance time. When the external fuel tank is provided for auxiliary expansion of the helicopter, the external fuel tank has no supporting point and the installation is unstable. [0003] Therefore, in order to solve the above problems, a short wing of...
