Projection liquid e.g. water repellent liquid, projecting system for windcreen of aircraft, has compressor compressing gas to circulate in pressurized gas circuit, and arranged near spray nozzles and in downstream of air inlet of circuit

摘要

The system (100) has a projection liquid supplying circuit (101), and a pressurized gas supplying circuit (102) purging the projection liquid supplying circuit. Spray nozzles (114) are arranged downstream of the supplying circuits and projects projection liquid e.g. water repellent liquid, and pressurized gas on a windscreen (111) of an aircraft. A compressor (107) compresses the gas to circulate in gas circuit. The compressor is arranged near the spray nozzles and in downstream of an air inlet (108) of the gas circuit.
