Engine turbo starters

  1. 1. TURBO-STARTER <ul><li>INTRODUCTION </li></ul>
  2. 2. TURBO-STARTER <ul><li>A TURBO-STARTER IS DEVISED TO PROVIDE INITIAL CRANKING TO AN ENGINE (WITH ROTORY/MOVEABLE PARTS) FOR SUFFICIENT DURATION </li></ul><ul><li>FOR INSTANTANEOUS AND RELIABLE STARTING WITHOUT GROUND SUPPORT (i.e. SELF-CONTAINED UNIT WITH SHORT STARTING CYCLE) </li></ul><ul><li>BY FORCING A HIGH-PRESSURE STREAM OF AIR/GASES THROUGH A HIGH-SPEED TURBINE (HENCE THE PREFIX TURBO) </li></ul><ul><li>- THE DRIVE FROM TURBINE IS DIRECTLY TRANSMITTED TO THE ENGINE THROUGH A GEAR MECHANISM. </li></ul>
  3. 3. CARTRIDGE TURBO-STARTER
  4. 4. CARTRIDGE TURBO-STARTER <ul><li>SOME MILITARY AIRCRAFT LIKE CANBERRA NEEDED TO BE STARTED QUICKER THAN THE ELECTRIC METHOD PERMITS AND HENCE THEY USE OTHER METHODS SUCH AS A CARTRIDGE TURBINE STARTER OR &quot;CART STARTER&quot;. </li></ul><ul><li>THIS IS AN IMPULSE TURBINE IMPACTED BY BURNING GASES FROM A CARTRIDGE, USUALLY CREATED BY IGNITING A SOLID PROPELLANT SIMILAR TO GUN POWDER. IT IS GEARED TO ROTATE THE ENGINE AND ALSO CONNECTED TO AN AUTOMATIC DISCONNECT SYSTEM, OR OVERRUNNING CLUTCH. </li></ul><ul><li>THE CARTRIDGE IS SET ALIGHT ELECTRICALLY AND USED TO TURN THE STARTER'S TURBINE. THE CARTRIDGE MAY LOOK LIKE A GUN SHELL/SMALL ROCKET. CARTRIDGE FIRING IS FOLLOWED BY PINCHING SOUND DEEP BLACK SMOKE AND IT GIVES AN ILLUSION OF ENGINE FIRE. </li></ul>

  6. 6. TURBO AIR STARTER TECHNICAL CHARACTERISTICS WEIGHT: 8,5 KG AIR FLOW-RATE (INTAKE): 0,9 KG/S TEMPERATURE (INTAKE): 530 °C EXPANSION RATIO: 4,07 OUTPUT SHAFT ROTATION SPEED: 57,700 RPM OUTPUT SHAFT POWER: 118 KW APPLICATIONS: ENGINE: EUROJET EJ200 HOST AIRCRAFT: EUROFIGHTER GMBH TYPHOON
  7. 7. LIQUID FUEL TURBO-STARTER
  8. 8. ADVANTAGES OF TURBO-STARTER OVER ELECTRIC STARTER
  9. 9. ADVANTAGES OF TURBO-STARTER OVER ELECTRIC STARTER <ul><li>INSTANTANEOUS START (i.e. SHORT STARTING CYCLE). HENCE IT IS OF PRIME IMPORTANCE WITH INTERCEPTOR AIRCRAFT. </li></ul><ul><li>RELIABLE & INDEPENDENT STARTING WITHOUT GROUND SUPPORT FACILITIES (i.e. SELF-CONTAINED UNIT) </li></ul><ul><li>WHEN MULTI BREECH CARTRIDGE STARTER OR LIQUID FUEL STARTERS ARE USED CONSECUTIVE STARTS WITH OUT RE-LOADING ARE POSSIBLE WITH MINIMUM TIME DELAY. </li></ul><ul><li>IT REDUCES LOAD ON THE AIRCRAFT BATTERIES & ELIMINATES THE NEED FOR HEAVY ELECTRIC CABLES. </li></ul><ul><li>SUITABLE FOR HIGH-POWERED/ HEAVIER ENGINES. </li></ul>
