Air inlet pipe network of aero-engine core engine and air inlet control method

The invention belongs to the field of engine tests, and particularly relates to an aero-engine core engine air inlet pipe network and an air inlet control method. The air inlet pipe network comprises a compressor (11), an outlet branch forms a second branch and a third branch, a water-cooling heat exchanger (13) is arranged on the third branch, a rear branch forms a fourth branch, a fifth branch and a sixth branch, an electric heater (14) is arranged on the sixth branch, the rear end of the sixth branch is connected with a mixer (15), the mixer (15) is further connected with the fifth branch, and the fifth branch is connected with the compressor (11). The rear portion of the mixing device (15) is branched to form a seventh branch and an eighth branch, a pressure stabilizing box (16) is arranged on the eighth branch, gas is supplied to a core machine after being subjected to pressure stabilizing and rectification, the second branch, the fourth branch and the seventh branch are connected with a deflation tower
