Ooops!
 Looks like there will be a big surplus market in aluminum matting then… F-35B Melts Temporary Airfields March 12, 2006: Testing of the STOVL (vertical take off and landing) version of the new F-35 has revealed that the heat from the F-35Bs engines will damage the aluminum matting used for rapidly constructed airfields. The F-35B engine heat won't damage the decks of current aircraft carriers, but the aluminum matting is toast, so to speak, and will have to be replaced with sturdier stuff. The F-35B is larger, and puts out more engine blast, than the current STOVL aircraft, the AV-8 Harrier. http://www.strategypage.com/htmw/htairfo/articles/20060312.aspx |

Aluminum is neat when it's melting.

I thought the ducted fan design kept the temp below the aircraft from getting too high.

I like the f-35 but why are we putting billions in a program that will be defeated at whim by a su-35+ or a euro fighter 2K? When was the last time Marines didnt have full air support? An unconventional war requires diffrent methods of attack, air power will establish less and less dominance in the war in Iraq.

To replace Harriers, F-16's, and A-10's. The F-22 is there to replace the F-15's in the air superiority role. |

Liberia, Somalia, and the TRAP teams in the Balkans, to name a few. |

So, throw some channel down where the ducts will be.

This is a CAS aircraft not an Air Superiority aircraft. Have there been fly offs between this aircraft piloted by US pilots VS SU-35's piloted by potential adversaries to determine that this aircraft would be defeated at whim? |

The airplane also relies on direct vectored engine exhaust. Nothing new here. |

The lift fan in the front blows ambient air, but the rear of the airplane is supported by the engine exhaust. The exhaust nozzle rotates downward. |

F-35… BACK TO THE FUTURE!!!!!!  YAK 141 'Freestyle' … first flew 1987. YAK info |

Of course, the YAK utilized a completely different design, and includes not one, not two, but three jet engines. What's more, it never made it out of the development stage. |

The lift fan from the front blowing ambient air block the heat from the rear exhaust from entering the intake. It keeps the flame from chocking out by sucking up too much heat. Keeping the intake air cool, not by cooling the exhaust, but by blocking the exhaust. |

Actually no it doesn't… The 3 bearing nozzle at the rear is the same design as on the YAK and was developed with design work bought from Yakolev. The only significant difference is that the F-35 uses a shaft driven fan rather than seperate engines up front, although the initial design concept did consider a separate lift engine. ANdy |

We really need an aircraft/aviation forum.

Doesn't surprise me. The AV-8B could light pavement on fire during a full powered vertical takeoff with a water-ethanol boost.

I know that. But I thought the volume of air coming form the ducted fan, cooled the jet exhaust air enough so that the ground temp actually stayed lower than the ground did fo a Harrier, which uses all exhausted air to keep it up. |
