In a rematch a second jet, this time running full military
power plus AFTERBURNERS, ran against a Competition coupe.
Once again the car won. You could hear the General's jaw drop

Man if they were going to use a souped up Dodge Viper they should have
raced it against an F110 or -229 F-16

Should be interesting. Hopefully the video clip will be out there to
find. I've got the one from Ripley's where an F-16 took on the
latest
and greatest, top of the line, Dodge Viper. The Viper (car) won to
the quarter mile mark but the F-16 overtook it and won to the half
mile mark. (I think a clean, low fuel load -229 F-15E might beat it
in the quarter though IMHO). I've also got a clip of a Hornet
getting
it's ass handed to it by a Formula 1 race car (what were they
thinking) and I've seen a clip of a Mig-29 getting beat by what
looked
like a teenager's muscle car. No a REAL muscle car not today's rice
burner wannabees. Looked like a jacked up in the back Nova with the
big wide tires on the back.

The US navy reportedly once pitted an F-14 against a hot-rod (for some
Hot Rodders magazine) and won,

which was somewhat unfair since the Tomcat used a catapult ;-)

If they used a top fuel dragster it would be close even if the Tomcat
used a catapult. Come to think of it the dragster might win.

I seem to recall that a top fuel dragster accelerates at 2 to 3 Gs;
anyone have better info?


A little calculation can sort this out.

The record the 1/4 mile is about 5.2 seconds and tops out
at around 280 mph or approx 410 feet per second

I'm almost positive they've busted 300 mph and five seconds.

Uh. . .yep

TOP FUEL DRAGSTER QUALIFYING

1. Doug Kalitta 4.499 sec.*/332.10 mph

2. David Baca 4.528 sec./320.36 mph

3. Larry Dixon 4.537 sec./332.75 mph**

4. Brandon Bernstein 4.557 sec./325.77 mph

5. Tony Schumacher 4.604 sec./304.53 mph

6. Darrell Russell 4.614 sec./319.29 mph

7. Doug Herbert 4.622 sec./284.62 mph

8. John Smith 4.643 sec./307.37 mph

9. Rhonda Hartman-Smith 4.648 sec./323.66 mph

10. David Grubnic 4.678 sec./303.50 mph

11. Paul Romine 4.686 sec./315.78 mph

Maybe they should have raced an F/A-18 against an AMC Hornet

A little calculation can sort this out.

The record the 1/4 mile is about 5.2 seconds and tops out
at around 280 mph or approx 410 feet per second

v= u+ a*t

from a standing start u=0 so

a= 410/5.2 or 78 feet per second per second
which is indeed about 2.5G

Dated data, Keith.
NHRA Top Fuel records are at least 332.18 MPH top speed and 4.477s elapsed
time, both by Kenny Bernstein in 2001.
Funny Cars are just a little behind at 326.87mph & 4.731s (different
drivers).

a=3.4g -or there abouts-

Or do like the US Navy did. There's a clip out ther of them using a
catapult to launch a car off the deck. I was somewhat disappointed as
I was hoping they'd really crank the juice up and LAUNCH that sucker
but it looked like it only went far enough out so the carrier wouldn't
hit it or something.


Or do it like the Fleet Air Arm did. . . and launch the ship's piano off
the catapault. Unfortunately the stress of the cat stroke was rather too
much for the instrument and it entered the oggin like so much matchwood.

Is the coefficient of friction of those special tires that high,
or do they use aerodynamic downforce to increase the traction?
If memory serves, the coefficient of friction of Formula One
racing tires is on the order of 1.2, but of course a drag slick doesn't
have to last nearly as long. One journalist wrote that, touching
a racing tire at operating temperature, it feels sticky, about like
wet bubble gum.

They sit at the start and deliberately induce wheelspin to get the tyres
good and hot, touch one of those tyres at racing temperature
and you'll get a 3rd degree burn

They use aerodynamic devices to increase down force (ie the
"normal force") but they also far exceed 1g acceleration off the
line (which is clearly impossible since the coefficient of friction
can not exceed one -it's a definition thing, just ask any physics
professor).
An engineer, of suitable background, will tell you the "grip" of
the tire is doing the trick.

Friction is one of those subjects that people discover, in fits and
starts every once in a while, to be yet still more complicated (and
interesting) at the micro/nano scale than they thought as of the last
go-round. I don't have access to hardcopy or online journals at the
moment, but if memory serves, Nature has run some interesting articles
over the last couple of years.
