HOW TO DRIVE A ROCKET DRAGSTER
First of all, you gotta have a lot of guts…but we'll let Dr. Miller
give you the blow-by-blow from a professional perspective.
"In preparation for a run, you check the nitrogen pressure in the air
bottles. Then you put in just enough fuel for a quarter-mile run and
for me an average run needed about 20-22 gallons of hydrogen peroxide
in the fuel tank. Check the safety valves, then close the vent on the
tank. You are pushed to the track just behind the starting line and
aimed straight down the race track. Obviously, you can't be cranking
the wheel all over in one of these cars, so you want the car straight
as a string. Then you put about 50-lbs. PSI on the fuel tank, which
allows you to preheat the silver screen catalyst in the rocket. I just
tap the throttle a little and this gives off a little steam. Once the
engine is cleaned from this pre-heating, you put about 700-pounds of
pressure on top of the hydrogen peroxide fuel.
"As I sit in the car on the line, I always pushed my head back in the
seat and fixed my eyes on a point in the horizon. Like it might be a
tree at the end of the track or some object like that. I take a deep
breath and then slam down on the throttle. Instantaneously, you're hit
with about 12 to 13 Gs and go into severe tunnel vision-it's sort of
like a gun scope. Naturally, you are getting pushed back in the seat
all the way down the track. I actually make about 20-30 corrections
in steering under those conditions. They are small in motion and that
might not seem like much, but as fast as I'm going they have to be precise
and done extremely quickly.
"After all, in a quarter of a second I'm going 60-mph, in .36 seconds
I've gone a 100 feet. I made a run in Holland one time where I had gone
1.606 at 307-mph at the eighth mile point. You have no time to hesitate
with these cars, it's gotta happen right now with the driver.
"I've heard it said that I've passed out after one of my three-second
runs, but that's not so. My body does take a bit of beating. At times,
I've gotten a bloody nose, bloody eyes, maybe an upset stomach, and
all in all, I need about an hour to recuperate from the run."
