CONSTITUTION: An aircraft rainfall test apparatus includes a water storage tank(100), a pump(200), a main head(300), a plurality of sub-heads and a jet nozzle(401). The water storage tank(100) receives and stores water from a water feeding source. The pump(200) supplies a water feeding pipe with water by pumping water stored in the water storage tank(100). The pump(200) includes a pressure adjusting part capable of adjusting pressure of water exhausted by a water exhaust part. The main head(300) distributes water after storing water supplied through the water feeding pipe. The sub-heads spray water supplied from the main head(300) on a corresponding part of the airplane.
