Aero Engines And Transmission test bench

Transmission test bench for Aero engines and Transmission play a critical role in the design, 发展, and validation of aerospace components and systems, ensuring safety, reliability, and performance in the aviation sector.

We provide the torquemeters,联轴器, flywheels, spindles & test rigs for both helicopter and aero engine component testing.

This Solution is primarily designed to provide a high-speed torquemeter and coupling, intended for integration into high-power drivetrains that include a gearbox and dynamometer.

The key features of these products—specifically their ability to handle high speeds and tolerate various types of misalignment (radial, axial, and angular)—are essential components for building aero engine test systems. They are also critical for testing individual turbine or compressor units, ensuring precise measurements and reliable performance even under challenging conditions. The aircraft accessory gearbox test bench is an integrated technology platform that covers mechanical transmission test, hydraulics and lubrication, electrical automation, vibration and noise reduction, and other technical fields. It can perform no-load, full-load, and dynamic load tests on gearboxes.

For many consecutive years, we have been dedicated to the development of Aerospace test bench systems and have successfully designed and developed over 10 sets of such systems and equipment. The aircraft accessory gearbox test bench is an integrated technology platform that covers mechanical transmission, hydraulics and lubrication, electrical automation, vibration and noise reduction, and other technical fields. It can perform no-load, full-load, and dynamic load tests on gearboxes.

Additionally, through the development of this type of Aerospace test bench, patented technologies such as hydraulic closed-loop loading and high-speed, low-vibration structures have been created. These technologies can be widely applied to high-speed transmission test bench with speeds ranging from 1000 rpm to 3000 rpm. The testing system invovle mechanical systems, data acquisition and control systems (including vibration testing systems), hydraulic loading systems, equipment, and product lubrication systems.
