The invention belongs to the field of aircraft flight tests, and relates to a simulation electric load system for an aircraft engine airborne test. Comprising an air inlet, an air compressor, a motor, a plurality of one-way valves, a plurality of pipelines, an adjustable flow port, a resistance wire, an exhaust port, a display controller and a matched cable, the air inlet is communicated with the exhaust port through a first branch, the first branch comprises the pipelines and the one-way valves, the air inlet is communicated with the exhaust port through a second branch, and the second branch comprises the air compressor, the motor and the one-way valves. An inlet of the air compressor is communicated with the air inlet, an outlet of the air compressor is communicated with the interior of the exhaust port through a pipeline, a one-way valve is arranged on the pipeline where the air compressor is communicated with the interior of the exhaust port, an adjustable throttling port is formed in the pipeline inside the exhaust port, and a resistance wire is arranged in the pipeline inside the exhaust port. The output end of the motor is connected with a driving shaft of the air compressor, and the display controller is connected with the control end of the motor through a matched cable and used for controlling the motor.
