Pulse engine test run test system

The invention discloses a test run test system of a pulse engine. The test run test system comprises a hollow temperature test box; the temperature test box is respectively connected with the engine ignition system and the air supply system; a pulsating engine needing to be tested is arranged in the temperature test box; the air supply system is used for conveying dry air with target high temperature or target low temperature to the inner cavity of the temperature test box; the engine ignition system is used for igniting and starting the pulse type engine; the engine ignition system comprises a fuel subsystem and a combustion-supporting air inlet subsystem. The invention can solve the problems of long preparation period, high site requirement, cost increase and the like of the existing pulsating engine high and low temperature test run test, can meet the environment requirement and equipment requirement when the engine is subjected to the test run test in the high and low temperature environments, and has the
