JohnK Posted June 14, 2004 Share Posted June 14, 2004 I just watched a program about exploding myths, on this episode they were trying to recreate the chevy impala with jet assisted take off boosters on the back. The got an old chevy but noone would supply them with JATO's so they used hobby rocket motors which were more powerful than JATO's!!! Now it didnt take off like in the urban legend but it did go like a bastard! While they were discussing the project, out came this little nugget of info: 1lb of thrust = 2 HP How true that is I dont know, but it would sure help a launch at pod! They had 3 of the rocket motors fired sequentially to give 12 seconds of thrust. It pushed the ocean liner of a car from a rolling start upto ~150mph in that time. So the questions are, where can we get these "hobby" rocket motors? Who is going to design and build a frame for under the car? And will any drag strip in the land allow it?

paul_y3k Posted June 14, 2004 Share Posted June 14, 2004 i saw it too.... notice they used the suspension to point the car at the ground .. thats why it didn't take off. and pod allows the jet force cars to run so i dont see why not heheheh Quote Link to comment Share on other sites More sharing options...

Aerotop Dave Posted June 14, 2004 Share Posted June 14, 2004 I'd recommend a totally foolproof and 100% reliable method of turning them off though if for some reason you want to abort the run. And they would need to be damn well secured to the car. Can you imagine having a crash and one coming loose and zooting off into the crowd?

JohnK Posted June 15, 2004 Author Share Posted June 15, 2004 You cant stop a rocket! Once you have fired it you have no choice but to hold on. Quote Link to comment Share on other sites More sharing options...

Doughie Posted June 15, 2004 Share Posted June 15, 2004 Originally posted by JohnK You cant stop a rocket! Once you have fired it you have no choice but to hold on. mild edit to John's post : You can't stop a solid-fuel rocket. - you can stop a liquid-propellant rocket by just switching off fuel-feed. I'd imagine the rockets you can buy off-the-shelf will be Solid-fuel so yeah that's a one-shot thing. That's why on the Shuttle, NASA gets the main liquid-fuel engine all lit and ready to go, and at the last moment, they fire the SRB's (Solid Rocket Boosters) as if they need to abort take-off they can, as long as the SRB's aren't lit....
