X Prize Founder Launches Rocket Racing League

David Rosen writes "MSNBC reports a 'Rocket Racing League' is launching today. The man behind the $10 million X Prize for private spaceflight is joining forces with a venture capitalist who is also an Indy car backer to establish a NASCAR-like racing league for rocket-powered aircraft." The Rocket Racing League also has an official website which outlines some of the specifics behind the program.

Reminds me of Air Racing

[W.Mandamus]

Reminds me of the Air Races in the 20's and 30's that gave aviation its start. Undoubtably they hope for the same result.

F-Zero anyone?

[SSilver2k2]

I immediatly thought of F-Zero when I heard of this. Stuff like this has always interested me. :)

First Deaths?

[Rob Carr]

Deaths occur in racing sports like NASCAR, drag racing, cycling, and even running and triathlons. But what will public perception be the first time it happens in the RRL?

"Course?"

[mhollis]

I still don't understand what the course is supposed to look like: From the article:

Courses are expected to be approximately two miles long, one mile wide, and about 5,000 feet high, running perpendicularly to spectators. The rocket planes, called X-Racers, will take off from a runway both in a staggered fashion and side-by side and fly a course based on the design of a Grand Prix competition, with long straight-aways, vertical ascents, and deep banks.

5,000 feet is an altitude that may be covered in seconds by a rocket at speed. A two-mile length with a curved track, like Grand Prix race cars use would require a kind of manoverability not seen on any rocket-powered craft.

The competition would certainly bar solid rocket motors, which go full-out continuously and cannot be throttled or shut down. I cannot imagine any braking system that would allow such a craft to slow down adequately for a "turn." The dynamics of these racers would appear to all but defy anything we have ever produced.

And such a craft would not necessarily operate in outer space. The ability to manover like that is the kind of thing you would need a gravity well to check your speed.

You can help... call them pussies

John Carmack, author of the 3D first person shooter video games, Doom and Quake, has put his money to good use by funding a small group to build a reusable rocket. Is going to be running 3 flights an hour at the up-coming X-Prize Cup:

You might want to see his latest test at:

So my question to the NASCAR guys is this:

Are you going to let this geek make you look like pussies or are you going to show him how power engineering gets done?

Looks like Long-EZs

[vijayiyer]

They basically look like Long-EZs (The Burt Rutan designed kit plane, http://www.ez.org/), with rocket engines.

Gah. RTFA.

[everphilski]

RTFA.

5,000 feet is an altitude that may be covered in seconds by a rocket at speed. No, it will be covered at 5000/(Velocity in Feet Per Seconds) seconds.

With a max speed of 320 MPH (which you surely would not be doing in a maneuvering course) a two mile length of track would take 22.5 seconds per lap. Faster than NASCAR, yes. But that's the point.

The article specifically states kerosene engines. Kerosene is a liquid at all but the most extreme temperatures.

I cannot imagine any braking system that would allow such a craft to slow down adequately for a "turn."

It's called aerodynamics. Flaps. And you won't be gunning it most of the time. It depends on the course.

The dynamics of these racers would appear to all but defy anything we have ever produced.

Check out XCOR's website. The spec listed on the Rocket Racing website is very similar to the bird XCOR is currently flying, and will be flying at the XPRIZE cup.

And such a craft would not necessarily operate in outer space. No !@#$

Re:Non-chemical rockets

[AKAImBatman]

Nothing except for nuclear is going to surpass the energy densities of chemical rockets.

Laserbeam-powered, solid-fuel rocket. Just keep a ground laser trained on the exhaust cone of the craft, and you'll have a highly efficient craft with oodles of power.

There's also the question of how exotic are the engines allowed to get. Ramjets or other oxygen scoops might provide comperable power but better fuel economy. Not to mention the case of staging. Can the rocket be staged to drop mass in flight? What about the use of meta-stable fuels that require no oxydizer?

You get the idea.

Re:Reminds me of Air Racing, except

[RayDude]

These planes are going to be traveling at multiple times the speed of sound. Which means they can't race over populated areas because the sonic booms would disturb, shock and in some cases injur the inhabitants.

And because they are going so fast, they have to go in a straight line, or as straight as is perceivable from say a ground based observatory.

So they have to do it over land that has no population or over the ocean.

Either way, not many spectators can watch it live.

So now they have to shoot it with cameras, but from where? Another rocket plane? Not likely. The best thing is to have GPS tracking equipment on board which is then plotted on a web page and also shown on ESPN 8 (The Ocho). You watch by watching little dots move across the map at insanely fast speeds. Here's a sample of what you may see on the Tele.

Announcer 1: "Well, Jim their engines are humming and they're ready be dropped from their respective 747s, its just a matter of moments until the race is under way."

Announcer 2: "That's right John! And one hellofa race its going to be!"

Announcer 1: "And there's the master timer telling all their flight computers to initiate a full burn and release from the 747!"

Announcer 2: "Hopefully in reverse order John."

Announcer 1: "Ha Ha! Yes, hopefully in reverse order."

You see multiple views of the underside of various 747's with rocket planes dropping and then blasting away from the 747 at breathtaking speed.

Announcer 2: "Now if you're all paying attention to the GPS tracking at www.rocketrace.net..."

Announcer 1: "And we know you are, because there are over 20 million of you tuned to this webcast!"

Announcer 2: "Woe!!!! Ken Tirbanker's rocket just blew up. Ken's emergency beacon is active so we assume that his cockpit survived the explosion, lets see if we can find a satelite that could view the spectacle. And if his electronics are alive then maybe we can show his condition and talk to him while he floats to the water."

Announcer 1: "While Jim and the crew look for a satelite images and attempt to connect with Ken to discuss the explosion let me remind you that today's race is sponsored by Budwizer Beer, the beer for the Wizer beer drinker. How's it going Jim?"

Announcer 2: "We're still looking at clips, they lost Ken's uplink so the electronics are gone, hope he's okay ... [in the background] I told you we should have assigned satellites to each racer, instead of panning and scanning randomly ... yeah sure six hundred million to launch six more birds, so what, I can't find the damn video!"

Announcer 1: "The race is happening at 68 thousand feet on a course from Sydney to Los Angeles, the race is expected to last for less than two hours. At least for those who touch down in the desert. For Ken, its going to be a long couple of days."

Announcer 2: "Ah HA! We got it, where's the damn mouse, give me that! Here's, I'm putting it up on Monitor six, switch to it..."

And so on and so on.

Its all doable, its just a whole different scale...
