Problems solved by technology

Coaxial counter-rotating dual-rotor technology is a technology that uses two sets of rotors with the same rotational speed on the same axis and turns to the opposite rotor. Propellers, shortening the length of the fuselage and reducing the weight of the fuselage are one of the new development directions of the helicopter, but this technology puts forward high requirements for the rotor test, such as limited to the narrow space between the inner and outer shafts, and the interaction of measuring equipment. Due to the impact and structural limitati

Abstract

The invention relates to a device for testing a coaxial inversion rotor wing of a helicopter, wherein a motor is installed on a base and connected to an inner shaft transmission and an outer shaft transmission in series; the output end of the inner shaft transmission is connected with the inner shaft of the rotor wing; the output end of the outer shaft transmission is connected with the outer shaft of the rotor wing; the inner shaft and the outer shaft are installed on a bearing base of the inner shaft; both an inner shaft coupler and an outer shaft coupler are provided with a torque meter; and a torque scale is installed on the bearing base. According to the invention, the thinking mode that the transmissions for rotor wing test must be gearboxes integrated together is broken through; by means of two gearboxes which are associated in function and independent in structure, tests of performance and reliability of the coaxial inversion rotor wing are realized; and the device is capable of respectively measuring dynamic data of lift force, torque and bending moment of two sets of rotor wings at the same time.

Description

technical field [0001] The invention relates to a helicopter rotor test device, in particular to a helicopter coaxial reverse counter-rotor test device. Background technique [0002] Helicopter rotor technology is one of the core technologies of helicopter development, and its test technology is the key technology. Helicopter rotor tests need to measure dynamic lift, bending moment, torque and other items. At present, the traditional helicopter rotor measuring device can only measure the lift, bending moment and torque of a single rotating rotor. Coaxial counter-rotating dual-rotor technology is a technology that uses two sets of rotors with the same rotational speed on the same axis and turns to the opposite rotor. Propellers, shortening the length of the fuselage and reducing the weight of the fuselage are one of the new development directions of the helicopter, but this technology puts forward high requirements for the rotor test, such as limited to the narrow space bet...
