  • 1. JET ENGINE BASIC AVIOTRIX www.aviotrix.com
  • 2. TYPES OF ENGINE  Piston engine (Reciprocating engine).  Gas turbine engine. -Jet Engine.
  • 3. When it is invented?  Frank Whittle’s patent award on the jet engine in 1930 and his static test of a jet engine in 1937.  The gas turbine in replacing the reciprocating engine as a power plant for high-speed aircraft.  This is one of the growing at a rapid pace all over the world.
  • 4. Description of Gas Turbine  The gas turbine is a machine that burns fuel to provide energy to create a moving flow of air.  In both the gas turbine and the motor car engine, air is compressed fuel is added and the mixture is ignited.  The resulting hot gas expands rapidly and is used to produce the power.
  • 5. Cycles and Laws  The fundamental thermodynamic cycle on which gas turbine engines are based is called the Brayton Cycle or Joule cycle.  A jet engine employs Newton’s laws of motion to generate force.
  • 6. Brayton Cycle (Open)
  • 7. Brayton Cycle (Close)
  • 8. Perfection in engineering  There are four main types of gas turbine: • The Turbojet , • The Turbofan, • The Turboprop, • The Turboshaft.
  • 9. Turbo Jet Engine  Simplest form of gas turbine  High velocity hot gas provides thrust  High fuel burn and high noise levels Application:  Most famously the Olympus 593 that powered Concorde  Military aircraft
  • 10. Turbo Prop & Turbo Shaft The exhaust stream drives an additional turbine  This turbine drives a propeller or a helicopter rotor system.  The propeller accelerates air generating thrust or lift. Application  AE2100, the world’s leading high power turboprop, powering the Hercules C-130J.  RTM322 turbo shaft powering Apache helicopters.
  • 11. Turbo Fan Also called the bypass engine.  Bypass and core flows both provide thrust, with the bypass flow accounting for around 80 per cent of the total thrust.  More environmentally friendly with better propulsive efficiency and lower noise levels. Application:  RB211 and the Trent family such as the: Trent 1000 powering the Boeing 787 Dreamliner™ The latest Trent powering the Airbus A350 XWB
  • 12. Types of Shaft  There are two types of shaft used in gas turbine.   Two Shaft, Three Shaft. Three Shaft:  Shorter, stiffer shafts allowing improved performance retention  Optimised blade speeds improving engine efficiency.  Lighter weight engines resulting in higher revenue earning potential.  Modular design allowing easier maintainability
  • 13. Fan (Low Pressure Compressor)  Its primary jobs are drawing air into the engine, compressing the bypass stream to produce 80 per cent of the engine’s thrust.  The fan system must be strong, light and quiet.  The tip of the fan blades can be travelling at speeds of over 1000mph.
  • 14. The Compressor  The compressor is made up of the fan and alternating stages of rotating blades and static vanes.  This compressor having eight intermediate pressure stages and six high pressure stages.
  • 15. The Combuster  There are Three Types of combustion chamber.  The multiple chamber,  The tubo-annular chamber and  The annular chamber.
  • 16. The Annular Combustion Chamber  The annular combustion chamber is located within a casing structure.  Kerosene is introduced through fuel injectors into the front of the chamber.  It is made up of nickel alloy walls.  Cooling air and thermal barrier coatings are therefore used to protect the walls and increase component lives.
  • 17. The Tubine  The turbine is an assembly of discs with blades that are attached to the turbine shafts, nozzle guide vanes, casings and structures.  The turbine extracts energy from the hot gas stream received from the combustor.  In a turbofan this power is used to drive the fan and compressor.  Applied by thermal barrier coatings.
