DEVICE FOR CONTROL OF AERODROME AIR-CONDITIONER Russian patent published in 2002 - IPC

FIELD: ground aeronautical engineering; servicing aerodrome air-conditioners for creating required conditions in aircraft salons during ground preparation. SUBSTANCE: proposed device has switches and actuating members, as well as pressure sensor and first NOT gate and first switch connected in series. Novelty of invention consists in introducing second NOT gate and second switch connected in series and storage gate whose second input is connected with output of second NOT gate and output is connected with input of first NOT gate. Input of one of actuating members is connected with output of first switch whose input is connected with input of second NOT gate, output of respective indicated actuating member of switch and first input of second switch whose second input is connected to output of pressure sensor. Outputs of other switches are connected to inputs of respective actuating members. EFFECT: enhanced reliability of aerodrome air-conditioner due to avoidance of failure in preparation of flying vehicles for flights. 1 dwg
