Presentation on electronics control system in aircrafts

  1. 1. Presentation On Electronics Control SystemIn Aircrafts PREPARED BY: SADDAM HUSSAIN EC(4th Year) 1
  2. 2. ABSTRACT Electronic control system is used to install and maintain the sensors which measure and report flight and engine parameters.1-SU-30.2-Electronic flight instrumentation system.3-Full Authority Digital Electronics Control (FADEC).4-Limited Authority Spark Advance Regulator. 2
  3. 3. ABOUT HINDUSTAN AERONAUTICS LIMITED (HAL)HAL was established as Hindustan Aircraft Limited inBangalore in 1940 by the late Seth Walchand Hirachand toproduce military aircraft for the Royal Indian Air Force.Hindustan Aeronautics Limited came into existence on 1stOctober 1964 by the merger of Hindustan Aircraft Limitedwith Aeronautics India Limited and Aircraft ManufacturingDepot, Kanpur.The Gov. of India became a share holder in March 1941 andtook over the management in 1942.Today H.A.L has 19 production units and 10 Research andDesign Centers in 8 location of India.HAL is one of the largest aerospace companies in Asia with itsannual turnover to be running above US$ 2 billion. 3
  4. 4. SUKHOI-30 4
  5. 5. SUKHOI SU-30The Sukhoi Su-30 is an air superiorityfighter jointly developed by RussiasSukhoi Aviation Corporation and IndiasHindustan Aeronautics Limited (HAL).Sukhoi Su-30 is a heavy, all-weather, long-range fighter.The Su-30 is a highly integrated twin-finned aircraft.The Su-30 is a multirole fighter. 5
  6. 6. SUKHOI SU-30The aircraft is fitted with a satellitenavigation system (GPScompatible), which permits it to makeflights in all weather, day and night.SU-30 is equipped with a moderndigital weapons control system as wellas anti-jamming features.The Su-30 is capable ofaccomplishing a wide variety ofcombat mission at significant distancefrom the home base, in any weatherconditions. 6
  7. 7. Electronic Flight Instrument SystemAn electronic flight instrument system is a flight deckinstrument display system in aircrafts.Which the display technology used in electronic ratherthatn electromechanical.EFIS consists of PFD,MFD,EICAS.An EFIS installation will have the following components:1-Display2-Controls3-Data ProcessorsA basic EFIS might have all these facilities in the one unit. 7
  8. 8. Electronic Flight Instrument System One Engine & Warning Display (EWD) for Engine Instruments and Crew Alerting System, Checklists/ Procedures management Two Multi Function and Displays permanent data. (MFD) for Navigation and aircraft system synoptic. Two Primary FlightTwo Primary Flight DisplaysDisplays (PFD) for EFIS functions(PFD) for EFIS functions (EADI/EHSI)(EADI/EHSI) Control panels for system settings 8
  9. 9. DISPLAY UNITS:1-Primary Flight Display* On the flight deck, the display units are the most obvious parts of anEFIS system.* The PFD displays all information critical to flight, including calibratedairspeed, altitude, heading, attitude, vertical speed and yaw.* The PFD is designed to improve a pilots situational awareness byintegrating this information into a single display instead of six differentanalog instruments.* LCD units generate less heat than CRTs; an advantage in acongested instrument panel. They are also lighter, and occupy a lowervolume. 9
  10. 10. The Multi Function Display (MFD)-1-The MFD (multi-function display) displays navigational and weatherinformation from multiple systems.2- . MFDs are most frequently designed as "chart-centric", where theaircrew can overlay different information over a map or chart.3- MFDs can also display information about aircraft systems, such asfuel and electrical systems (see EICAS, below). 10
  11. 11. Engine indications and crew alerting system (EICAS) /electronic centralized aircraft monitoring (ECAM):1- EICAS (Engine Indications and Crew Alerting System) displaysinformation about the aircrafts systems, including its fuel, electricaland propulsion systems (engines).2- EICAS improves situational awareness by allowing the aircrew toview complex information in a graphical format and also by alerting thecrew to unusual or hazardous situations.Control Panels : The pilots are provided with controls, with which they select displayrange and mode (for example, map or compass rose) and enter data(such as selected heading).Where inputs by the pilot are used by otherequipment, data buses broadcast the pilots selections sothat the pilot only needs to enter the selection once. 11
  12. 12. Advantages Of EFIS-1-Offers versatality.2- Flexibility afforded by software modifications.3- Minimizes costs.4- EFIS system can be updated with new software to extend its capabilities.5- Degree of redundancy is available. 12
  13. 13. Full Authority Digital Engine Control (FADEC): Full Authority Digital Engine (or Electronics) Control(FADEC) is a system consisting ofa digital computer, calledan electronic engine controller (EEC) or engine controlunit(ECU), and its related accessories that control allaspects of aircraft engine performance 13
  14. 14. FUNCTIONS OF FADEC:~ Provides optimum engine efficiency.~ Provides efficient engine operation.~ Controls engine starting & restarting.~ Controls fuel flow.~ Manages the power efficiently.~ Manages the wind conditions, runway length. 14
  15. 15. Advantages of FADEC:~ Better fuel efficiency.~ Automatic engine protection against out-of-tolerance operations.~ Safer as the multiple channel FADEC computer provides redundancy in case of failure.~ Provides semi-automatic engine starting.~ Better systems integration with engine and aircraftsystems.~ Can provide engine long-term health monitoring and diagnostics.Disadvantages of FADEC:~ If a total FADEC failure occurs, the engine fails.~ High system development and validation effort due to thecomplexity. 15
  16. 16. Limited Authority Spark Advance Regulator:~ FIRST microprocessor based engine control systemapproved the FAA for general aviation piston aircraft.~ To establish and command the optimum ignition timingand spark energy to produce maximum torque from theengine.~ LASAR has an inherent mechanical magneto backupsystem. 16
  17. 17. Benefits Of LASAR:~Better engine starting with three times more sparkenergy and higher output voltage.~Smoother transition in ignition timing from enginestart to idle .~Faster Rate of Climb.~Increased spark plug life.~EGT reduced by 150°F on average.~Up to 12% Reduced Fuel Consumption.~Up to 8% Increased Horsepower. 17
