Devices operated by hydraulic system in aircraft

  1. 1. DEVICES OPERATED BY HYDRAULIC SYSTEM IN AIRCRAFT LECTURER’S NAME: DR.SOFIAN MOHDGroup Members: 1) AMIRUL IMAN BIN HASRI AD110155 2) JASWANT SINGH BAL AD110177 3) AMAL IQMAL BIN ADNAN AD110189
  2. 2. AIRCRAFT HYDRAULIC SYSTEM A crucial component to operate modern aircraft (mainly for large commercial airplane). Helps to ease the work of controlling an aircraft without concerning on sloppiness. Create large/unlimited force by exerting minimal strength on control system (compared with other fully mechanical operated aircraft)

  10. 10.  Cable or high steel rod used as flight control. Low cost. Cable is strong enough to flight control. Cable is made from strong and high tension string. If hydraulic used, might be not efficient for the performance of DA-40 because strength to weight ratio is really important to make an aircraft fly. Sometimes light aircraft is equipped with hydraulic system, if then, the pressure used of that such aircraft is around 1000psi and below. Mineral-base Fluid MIL-H-5606
  11. 11. Boosted control system This is a simplified boost system. When the pilot moves the column, tension in the cable or rod also opens a valve letting pressure from a hydraulic or pneumatic pump expand a slave cylinder that assists moving the control. The control column can be moved by raising and lowering the elevator but a considerably more force is required.Booster Assemblies The booster system is designed so that the pilot has a normal feel of control forces when hydraulic pressure is available to the booster cylinders. Hydraulic flight control boosters operated by both hydraulic systems are incorporated in each of the three surface control system.

  13. 13. Landing gear• Similar landing gear with a commercialaircraft, which is tricycle landing gear.• Slight difference in type of hydraulicsystem used to generate power tooperate the landing gear, due to jetfighter flexibility and speed inperformance.•Hydraulic fluid : Exxon Hyjet V (Type V)•Type of hydraulic pump : Piston pump
  14. 14. F-22 Raptor (Military Aircraft) Hydraulic system with more than 4000psi. Thick hose The hydraulic system includes four 72 gallon-per-minute pumps and two independent 4,000 psi systems. Large power pump and accumulator. It exposed with high speed so require more energy. Sometimes require large reservoir. Hydraulic fluid used is such type of Synthetic Fluid MIL-H-83282. Non-petroleum base hydraulic fluid for use in high performance piston engine and turbine powered aircraft.
  15. 15. COMMERCIAL AIRPLANE(BOEING 737)
  16. 16. Utility systemLanding gear Previously , cable system was introduce in the early days to operate landing gear system. Due to lack in efficiency, hydraulic system was widely use these days. An easy working principle, with a push of button ,the landing gears can be set to radial movement of gears that is powered up by hydraulic system to steady state of take-off or during/after landing. Fluid used for this hydraulic system is :Skydrol 5 Hydraulic pump used in this part of system is : Piston pump
  17. 17. Brakes Use to reduce aircraft speed on ground Fully functional with hydraulic system (conventional brake drum is no longer in use) Fluid used : Exxon type 4 Type of hydraulic pump used : Vane pump
  18. 18. Gear steering, Cargo door, Passenger door Fully functional with hydraulic system Fluid used :Exxon type 4 Type of hydraulic pump : Vane pump
  19. 19. Braking system• Used to reduce airplane speed ,no means ofcable• Fully functional hydraulic system•Hydraulic fluid : Exxon Hyjet V (Type V)•Type of hydraulic pump : Piston pumpGear steering, Cargo door, Passenger door*Similar to commercial airplane and light aircraft*
  20. 20. Empennage hydraulic system -Empennage need hydraulic system because of the efficiency of system compared to cable or steed rod connected to empennage. -The fluid that used for empennage hydraulic system is DTD585. This fluid is most suitable for this system because of the pump use for this hydraulic not required large force compared to other. -That fluid also cannot expands due to high temperature. -The pump used for this hydraulic is really small than in aileron part.
  21. 21. Boeing 737 Most commercial airliners planes using in range 3000 to 4000 psi systems (although some new military aircraft have made the move to 5000 psi) of hydraulic system. Therefore , piston pump is used to control hydraulic fluid flow through Boeing 737 hydraulic system Synthetic based fluid is used to run the system which is Exxon type 4
