The invention discloses a spray test air supply device and method for aircraft testing. The spray test air supply device comprises a heat preservation box body, an air supply system and a temperature control system. The air supply system and the temperature control system are both arranged in the heat preservation box body, the air supply system comprises an air pipeline heater, a first main pipeline, a second main pipeline, an air outlet pipeline and a first electric control valve arranged on the first main pipeline, one end of the first main pipeline is communicated with an external air source, and a first branch pipeline and a second branch pipeline are connected between the first main pipeline and the second main pipeline in parallel. A second electric control valve is arranged on the first branch pipeline, a third electric control valve is arranged on the second branch pipeline, and the other end of the second main pipeline is communicated with the air pipeline heater. The air supply device for the spray
