Abstract

The invention discloses a propeller aircraft engine test system and test method.The system comprises a base, a propeller aircraft engine, a transmission mechanism, a rotating speed and torque measuring mechanism and a sliding mechanism, the sliding mechanism comprises a sliding rail, a base and an electric push rod, and the rotating speed and torque measuring mechanism is a rotating speed and torque sensor; the transmission mechanism comprises a first transmission part and a second transmission part, the first transmission part comprises a first bearing box and a first transmission shaft, and the second transmission part comprises a second bearing box and a second transmission shaft; the method comprises the following steps: 1, mounting a first transmission part; 2, mounting a rotating speed and torque sensor; 3, mounting a second transmission part; 4, propeller installation; and 5, testing the propeller aircraft engine. According to the invention, the performance test of the propeller aircraft engine under the condition of taking the propeller as the load is realized, and the actual working condition of the propeller aircraft engine is simulated more accurately.

Description

technical field [0001] The invention belongs to the technical field of propeller aircraft engine tests, and in particular relates to a propeller aircraft engine test system and a test method. Background technique [0002] The characteristics of a propeller aircraft engine when the propeller is the load is the most important characteristic of the propeller aircraft engine. The propeller characteristics of the propeller aircraft engine refer to the change of the torque, power and other parameters of the engine with the engine speed when the propeller is the load of the propeller aircraft engine. Accurate and reliable measurement of the propeller characteristics of propeller aircraft engines is of great significance for evaluating the performance of propeller aircraft engines. [0003] For the propeller aircraft engine, the traditional test method is to use the propeller aircraft engine to test and evaluate the engine, that is, the propeller aircraft engine uses the dynamometer...
