DEVICE FOR AUTOMATIC CONTROL OF FLYING VEHICLE FUEL UTILIZATION Russian patent published in 1995 - IPC

FIELD: aeronautical engineering. SUBSTANCE: device for automatic control of utilization of fuel from tanks fed in three stages by pumps 27, 28 and 31 has level sensors 1, 14, 21 and pressure pickups 20, 32, NAND gates 2, NOR gates 8, 22, time counters 10, 23, amplifiers 18, 24, switching elements 19,25, 26, 29 arranged in control channels; first stage fuel utilization control channel is additionally provided with NAND gate 15 and OR gate 13, (R-C=) circuit 5, inverters 6,7, resistor 12, flip-flop 16 and four logic switches 3, 4, 9, 11. Outputs of sensor 1 are connected with gate 2 whose output is connected with first input of switch 3 whose output is connected via counter 10 with first input of switch 9 and second input of switch 11. Output of switch 4 is connected via (R-C=) circuit 5 to inverter 6 whose output is connected to second inputs of switches 3, 4, gate 8 and inverter 7 which is connected with first inputs of switches 9 and 11. Additional NAND gate 15 is connected with 3rd stage level sensor 14, flip-flop 16, gate 8, gate 13 and switching element 19 via amplifier 18. During operation of device, algorithm of operation of system taking into account holding fuel reserve in tanks is realized. EFFECT: extended functional capabilities through program action taking into account holding fuel reserve in tanks. 1 dwg
