Abstract

A large six-component measurement and angle-variable support device comprises a base, a six-component measurement and in-situ calibration device, an angle-variable device and locking devices. The six-component measurement and in-situ calibration device is arranged on the base. The angle-variable device is arranged on the six-component measurement and in-situ calibration device. The locking devices are located on the two sides of the angle-variable device. Before test, an engine is arranged on the angle-variable device, and initial calibration is conducted through the six-component and in-situ calibration device; after calibration is completed, the locking devices and an upper platform of the angle-variable device are locked and fixed, and impact loads borne by the engine when a high altitude flow field is established in the initial stage of the test are transmitted outward so that the six-component measurement and in-situ calibration device can be protected against damage; after the flow field is stabilized, rapid unlocking is achieved between the locking devices and the angle-variable device, the angle-variable device is rotated by different angles according to the requirements of the test, and force and torque of the engine at different angles are tested through the six-component measurement and in-situ calibration device.

Description

technical field [0001] The invention is applied in the ground test drive test of the aerospace engine under the condition of high altitude environment and large Mach number. Background technique [0002] Similar rocket free-jet test equipment in the United States, Russia, Japan and other countries has been in operation for many years. Most of the matched force measurement devices are single-component or three-component force measurement equipment. No equipment that simultaneously measures six-component force and moment has been found. The most representative is the NASA LANGLEY 8ft high-temperature wind tunnel in the United States, and its matching force-measuring equipment also has three longitudinal components, namely axial force, normal force and pitching moment. There are similar equipment used in the pre-research stage in China. The matching force measuring equipment has a small size and a small load measurement range. The force measurement uses an integral balance stru...
