- 3. 3 Pratt & Whitney'sF135 propulsion system is the engine of choice for the F-35 Lightning II. Primary propulsion for the F-35 is supplied by the Pratt &Whitney F135 turbofan series.The F135 is an afterburning turbofan system delivering 25,000lbf on dry thrust with up to 42,000lbf on full afterburner.

- 6. 6 POWER SYSTEM The F-35has 3 electrical systems, - 28VDC system being used to power avionics. - 270VDC system used to power high-power systems like the electro-hydrostatic actuators (which replace conventional hydraulic systems for control surfaces) and starter motors, - 115VAC system used for powering certain bombs / missiles that require it.
- 7. 7 MAXIMUMTHRUST &THRUST-WEIGHT RATIO Thequoted thrust-to-weight ratio indicates the performance of the engine or vehicle and represents maneuverability of the aircraft.

- 9. 9 STOVL Main EngineComponents The three main components of the F135 that enable both types of airborne flight are - The Exhaust Nozzle - The Lift Fan - The Roll Posts (Swivel) Exhaust Nozzle The exhaust nozzle is the most important part of the F135 engine. During horizontal flight, 100% of the thrust generated is due to the exhaust nozzle. During vertical flight, about 46% of lift generated is used to keep the jet stabilized.
- 10. 10 HOW AIR FLOWSWHEN PLANE IS AIRBORNE AND WHEN ITTAKES OFF/ LANDSVERTICALLY Lift Fan The lift fan is the second most crucial aspect of the F135 engine It forces air downwards 20,000lb of lift Roll Posts Placed under both wings, Although the roll posts only provide about 8% of lift need to keep the F-35 jet vertical in flight, they are absolutely necessary as the prevent rolling clockwise or counterclockwise with the wind.

- 12. 12 Yes, F-35 LightningII allows air-to-air fueling through AirTankers via two systems. DOES IT ALLOW MID-AIR FUELING?
- 13. 13 i) In theAerial Boom System, used primarily by the Air Force, the receiving plane flies in close formation to the tanker. A boom operator in the tanker then flies a rigid boom into a receptacle on the top of the aircraft.

- 15. 15 The drogue stabilizesthe hose in flight and provides a funnel to aid insertion of the receiver aircraft probe into the hose. Most modern versions of the probe are usually designed to be retractable when not in use. Aerial Boom System provides High rate of Fuel transfer but one aircraft at a time but Probe-and-Drogue refuels multiple aircrafts simultaneously at lower Fuel transfer rate.

- 17. 17 FUELTYPE & COMBUSTION JETA-1 OR AVTUR(AviationTurbine Fuel) is a type of fuel used in F-35. JET A-1 is an aviation fuel formerly known as "kerosene" which is suitable for most jet aircraft. It has a minimum flashpoint(combusts) of 38°C and a maximum freezing point of -47°C. JET A-1 is the principal fuel used for jet turbine engines. It is also used in general aviation for compatible diesel engine planes.
