Abstract

The invention provides an aero-engine ground table test air inlet resistance measuring device, which comprises a fixed frame, a first movable frame arranged on the fixed frame, and a simulation engine fixed above the first movable frame, the flow guide basin is arranged on the head portion of the simulation engine, the working force measuring sensor is used for measuring force transmitted by a first movable frame, a labyrinth section is arranged between the flow guide basin and a flow pipe of the simulation engine, the labyrinth section transmits air inlet resistance borne by the flow guide basin out, and the working force measuring sensor is used for measuring the force transmitted by the first movable frame. Therefore, the resistance of the air inlet channel can be directly measured. According to the aero-engine ground table test air inlet resistance direct measuring device and method, the device can directly measure the air inlet resistance through the tension-compression force sensor, and the method is not affected by the quality of a flow field of a test workshop.

Description

technical field [0001] The invention belongs to the field of aero-engine testing, and in particular relates to a device and method for measuring the resistance of an air inlet of an aero-engine ground platform test. Background technique [0002] Thrust is the most important performance parameter of an aero-engine, and the calculation of engine performance parameters such as fuel consumption rate is related to thrust, so the thrust of the engine must be accurately measured. During the test of the engine on the ground platform, due to the limited space of the test workshop on the ground platform, the velocity of the airflow passing through the test workshop is not zero. The force in the opposite direction is the inlet resistance. The inlet resistance will directly affect the results of the engine thrust measurement, and only the accurate measurement of the inlet resistance can accurately correct the thrust test results of the test bench. [0003] The current measurement meth...
