Tester for simulating cooling environment of engine duct

The invention provides a tester for simulating a cooling environment of an engine duct. The tester comprises a high-pressure vortex fan, a tester rear cover and a tester shell, the tester shell is connected with an air pipe through the tester rear cover, and the air pipe is connected with the high-pressure vortex fan; the air pipe is provided with an air pipe pressure relief hole, the tester rear cover is provided with a temperature transmitter and a first pressure transmitter, and the tester casing is provided with a second pressure transmitter and a pipeline wind speed measuring instrument. According to the engine duct cooling environment simulation tester, friction work of a cooling medium is influenced by changing flow resistance, and controllable temperature rise of the cooling medium is achieved; the rated output thermal stability verification of the generator in an engine cooling environment is realized, and the safety of the engine after installation is ensured; the problem that functional performance
