| Is the raptor cabable of the viking take off? Im assuming it can, and probably better then the F-15. Anyone know? |

Yes it is...Yes it's KEWL... They just started allowing pilots to do them here in Marietta...I have seen three or four...We always have a F-16 Chase plane for the flights around here...It is amazing to see the Raptors performance vs the F-16...Poor little F-16 just can't keep up... 
I'm a little jealous of the AF guys on this website that are workin' on the jet...they get to see allot more cool stuff from the Raptor than we do...I expect more guys to chime in here...and I think we'll hear some better stories than mine... |

| Raptor is most definitely capable of a Viking Takeoff. It's thrust to weight ratio is far superior to the F-15's and it has lower drag than the F-15. |

In all fairness to the Marietta chase F-16s...
Either 62-86 or DH-1 are the only chase birds used at Marietta. Simply put a 25 year old B model and a 12 year old siezed Pakistani B model aren't exactly representative of current production F-16's. The Ft Worth chase bird CD-15 is a modied blk 50 with a GE-132 in it and it will more than hold its own. Its probably the fastest F-16 in the world. We just don't share it with Marietta. |

Aww...I'm just playin' with ya...The F-16 is an awesome aircraft!!...I do know it's a quite capable fighter jet...It is really something to see both of them standing on their tails, burners lit...climbing like home sick angels...I'm just happy to be able to see it!!!
62-86..is that the ED ship??...They have parked it in our hanger when bad weather was in the area...You can tell it's old...but it's still really sweet!!!...I imagine if it could talk it would have some really great stories...It even smells cool...lol...I like that airplane...I have never gotten to close to the grey one with LM on the tail (the Pakistani B model??)...I'm sorry I am not quite the F-16 efficanado as allot of folks around here are...I just joined this site...It's really great and I'm learning allot...
I have been out to your plant in the past...I can't tell you how cool it was!!!...a truly awesome expierence...got a guided tour one night and saw the JSF prototype or mock-up??...and the VISTA...man...I loved it!!..
Thanks for the work you do!! |

And even money says the -22 can leave even CD-15 in it's wake. I was at Eddies Air Patch during the ATF DEM-VAL and watched on multiple occasions the YF-22 or -23 zooming down the light altitude supersonic corridor, F-15 on its wing (in full blower I might add) and the poor little Viper waaaaaaaay back there  |

| Whenever thrust exceeds weight, a vertical acceleration, (speeding up) is possible. The Raptor's thrust exceeds gross weight by some 15K - 25K lbs, I think the Raptor can possiblly go sub-orbital, assuming the life-support is adequate. It's probably been done, but no-one will tell. JR can probably tell you about that in the F-104. |

Salute!
QUICK!!! Before an active pilot or aero-dweeb replies......
Sorry to pop your bubble, Allen, but more thrust than weight doesn't guarantee vertical climb, much less acceleration in the vertical.
You must add drag, and even the early Vipers and Eagles couldn't maintain a constant speed going vertical, and they were lighter and had lots less drag than the newer models.
Secondly, until they add RCS doofers, even the Raptor will have trouble keeping the pointy end forward above 100K or so.
later, |

The Raptor looks pretty Sierra Hotel going into a max climb! At Tyndall, every once in awhile, you'll see one light the pipes and start his max climb, and then the second jet will be putting his gear up about the time lead is rotating at the end of the runway. Then, two will go into a max climb. They'll keep climbing until you can barely see them. Great stuff.

About the take-off capability of Raptor, according to the declaration of a test-pilot of Raptor last year: "It can take-off in to the sky with just 800 fts' (or about 244 meters') runway."
It is an extremely amazing performance for a large fighter...................... |

Gums - I know drag must be considered along with other factors. I was only implying an ideal situation, which never exists. Even as the atmospheric density decreases so will the performance in the vertical, simply trying to state a general condition with inherent factors not taken into account. I didn't compute anything anyway.
I will have an opportunity to fly something high-performance in the not-to-distant future, maybe an experiment at a safe altitude might be in order. Will post when this happens. |

Gums wrote, and I quote:
1) As you progress through more classes, you'll discover that "flat plate" drag model is only worthy at low mach #'s.
2) The turbofan does not get better at higher density altitudes, when in burner, it does acquire better performance at higher mach #'s.
3) Afterburnering turbofans use all the by-pass air to increase mass flow through re-heat, so thrust is better the faster you fly. |

He he he...
RCS doofers, you said it Gums! As Gums knows, even with those if you don't fly defined profiles you can still get your "six" in trouble and crash a perfectly good fighter. NF-104 for example.
My question is how would she breathe up that high? Even at Mach 1.0 you can experience an afterburner blowout at FL 600 in the Zipper.
That’s the kind of stuff you don't do with an aircraft that isn't made any more... |
