New 1/4 scale Turbine powered Jet Dragster.
Posted: March 25th, 2010, 1:09 pm
Hey All,
Just thought I'd let you know of my latest project, (I already have a 1/5 scale turbine powered machine), a new 1/4 scale after-burning turbine powered jet dragster, I have a new glass body, the same as Paul Songas' 1/4 T/F dragster body, from Mike at Legendary Reproductions....I have nothing but praise for Mike, he helped me no end to get the body to me here in Sydney, Australia, nothing was too much trouble for him.
A few specs for you. 1:1 jet dragsters normally run a 300" wheelbase chassis, somewhat similar to a T/F dragster I suspect, so a 75" wheelbase machine has been started. Weight of the car should be in the 12kg (~26lb) range. The old 1/5 car was just shy of 7kg (15.4lb) fully fueled and ready to run. The engine of the old car was a 20lb (9kg) static thrust with ~30-35% augmentation giving a total thrust of ~27lbs (12.2kg).
The new engine will "hopefully" be an ATJ-240Ti turbine, this engine has a static thrust of just over 53lbs, add the ~35% afterburner increase and we should have somewhere near 70lbs (~32kg) of thrust @ full noise. There will be twin 30" cross-form parachutes and twin rear wheel disk brakes to help with slowing down duties.
To be honest, this car will never be able to compete with the gas and nitro powered machines of similar scale over a scale 1/4 mile but that's not what I'm really after, I just like the challenge of the build and seeing it finally run on it's own.
I hope to keep you all up to date of progress as it happens.
Cheers,
Smithy.
