yup, we don't like flattops here

 

 

Who's ran them and had a catastrophy that wasn't tuning related?

 

Wellllll, Gober803 ran 22RE pistons on his destroked motor, you might remember that. Problem was, they were N/A pistons and didn't like heat. He raced a bimmer one day at 25psi, leaned out and BAM! number 3 piston turned into 100 pieces. Rod bent and crank was fine. Otherwise, with his SDS system, we had the thing rough tuned at 20psi and it ran like a bat outta hell!

I flipped a lid the first time I saw that. And yes, it was an interference motor like this.

 

Wow look ooooooooo aaaaahhhhhhh

CHIP what are you flying now?

Hornets in a month, nothing now. I'd fly a dog house if I could.

ever broke the sound barrier chip? if so what was it like if you dont mind me askin?

 

pretty uneventful, sorry. If you're in an airplane that's "capable" of it but not "designed" for it, then it's a little more interesting. The hornet is more than capable of it but not exactly designed for it. The T-45 is barely capable of it and totally not designed for it, so you get a big uncommanded roll to one side that's scary. In the Hornet, the same thing happens, but the flight control computers actually counter the adverse handling characteristics in the transonic region so it's transparent to the pilot. The jet knows it's about to happen and counteracts it with digital control inputs of its own, so it feels perfect to me. With variable inlet geometry, like the F-14, you really don't notice the transition from sub to supersonic at all. If you're up high, there's little difference between .9 mach and 1.1.

whats the fuel consumption at those speeds?

 

fuel consumption has more to do with throttle position than speed, sorta' like in a car, but assuming you mean to "maintain" those speeds, it's a lot. A hornet at cruise airspeed has about the same fuel burn as a 737 at cruise airspeed, so it's pretty efficient, considering the tactical nature of its exterior. A hornet at max grunt (as it's affectionately called) meaning full afterburner at maximum level speed will probably burn through all 12,500lbs of fuel in around 4 minutes and probably be doing about 15 miles a minute or around 900 statue miles per hour. JP-5 is like 6.8lbs/gal so I guess that's about 1800 gallons of fuel to cover 60 miles, or roughly 30 Gallons to the mile. That's roughly 450 gallons/minute or 183000lbs/hour. At max range cruise power settings we're burning about 4800lbs/hour, just to put it in perspective. the fuel consumption rate gauge doesn't even read accurately in AB. It doesn't go nearly that high.

 

needless to say, we don't spend much time in afterburner.

Yall need to get those fake jets that they had in the movie stealth where in like 20 minutes they were in a different country

 

 

the raptor's closer to that than you think, and the JSF will be close enough for me.
