BOOK TWO, BLOCK THREE-HYDRAULICS Flashcards
SAFETY PRECAUTIONS
CAUTION SHALL BE TAKEN TO AVOID INJECTION OF FLUID, HYD SYSTEMS ON P-3S ARE COOLED VIA HEAT TRANSFER THROUGH LINES IN THE #2 AND #3 TANKS. A MINIMUM OF 1000 LBS OF FUEL IS REQUIRED TO NECESSITATE COOLING.
HYDRAULIC THEORY BASICS
PASCAL’S LAW STATES THE PRESSURE EXERTED ANYWHERE UPON AN ENCLOSED LIQUID IS TRANSMITTED UNDIMINISHED, IN ALL DIRECTIONS, TO THE INTERIOR OF THE CONTAINER.
PUMPS, P3C
HAS THREE ELECTRICALLY (AC) DRIVEN HYDRAULIC PUMPS AND ONE ELECTRICALLY (DC) DRIVEN PUMP.
PUMPS, P8A
TWO ELECTRICALLY DRIVEN (AC) DRIVEN HYD PUMPS, AND TWO ENGINE DRIVEN PUMPS.
DISTRIBUTION
WHEN PRESSURE IS EXERTED ON AN ENCLOSED LIQUID FORCE IT IS EVENLY DISTRIBUTED TO ALL ACTUATORS AND OR VALVES THROUGHOUT THE HYDRAULIC SYSTEM THROUGH HYDRAULIC LINES.
VALVES
VALVES DIRECT THE FLOW OF FLUID TO THE VARIOUS ACTUATING UNITSADDITIONALLY EACH VALVE IS CONSIDERED A PART OF ITS RELATED ACTUATING SYSTEM.
RESERVOIRS, P3C
EACH HYDRAULIC SYSTEM HAS A FLUID RESERVOIR LOCATED IN THE HYDRAULIC SERVICE AREA. SYSTEM #1 RESERVOIR HASA TOTAL CAPACITY OF 5.6 GALLONS. SYSTEM #2 HAS A TOTAL CAPACITY OF 1 GALLON.
RESERVOIRS,P8A
EACH HYDRAULIC SYSTEM HAS A FLUID RESERVOIR LOCATED IN THE MAIN WHEEL WELL AREA. SYSTEM A AND B RESERVOIRS ARE PRESSURIZED BY BLEED AIR. THE STANDBY SYSTEM RESERVOIR IS CONNECTED TOT HE SYTEM B RESERVOIR FOR PRESSURIZATION AND SERVICING.
DEPENDENT EQUIPMENT/FUNCTIONS:BOOSTER ASSEMBLIES
THE BOOSTER SYSTEM IS DESIGNED SO THE PILOT HAS A NORMAL FEEL OF CONTROL FORCES WHEN HYDRAULIC PRESSUR EIS AVAILABLE TO THE BOOSTER CYLINDERS.
DEPENDENT EQUIPMENT/FUNCTIONS:ACTUATORS
TRANSFORM HYDRAULIC FLUID PRESSURE INTO MECHANICAL FORCE, TO PERFORM WORK.
