Cars and car troubles

Turbines...the Indy 500. Parnelli Jones...Mario Andretti.

I have a fond memory of that very brief period of time when this technology shocked "the brickyard". :)

The turbine car post made me remember these...Turbonique engines for dragracing

I remembering in the early 70s snailmailing was the only medium to get info
and sent for their catalog.





Gene Middlebrooks the owner of Turbonique was a NASA pro

vider who wanted to better dragracing
with turbines diectly geared thru normal drivetrain designs. These ehgines used liquid oxygen
and a rocket fuel called Thermalene (propil Nitrate) for combustion, They were turbines designed for operation
from a stopped rotor condition allowing for line lock braking systems to hold the vehicle still.
Various designs were made,including a rear axle assembly with a 1,000 horsepower turbine that
could be turned on with a switch,adding that horsepower figure to the power figure of the
installed reciprocating engine drive,sharing the same ring gear in the rear axle.

Captain Jack McClurg beat Grumpy Jenkin's Prostock car on a go-cart powered with two micro units
said to have gone into the high 5 second range at over 240 miles per hour.

I never knew they used them for drag racing. That's a very interesting article, thanks for sharing it!!!

As a dragracer,my take on the dragaxle would be to couple it with a huge displacement recip engine,a transmission braked automatically shifted gearbox with a rev indicating shift light to trigger the time to uncouple the recip event drive very early in the run...it would then let the turbine continue to spool up long after the work by the recip drive had been fully utilized for launch (torque) letting the turbine drive finish the pass well after the the jet drive was able to reach it's sweet spot and make it's power where it works best(horsepower) Most dragraces are won or lost during the first 60 feet of the 1/4 mile pass,when true chassis dynamics come into play with the best traction events. This is the torque event...a turbine is very inefficient at stopped thru low speeds. The recip event followed by the horsepower event finished long after the torque event was used up would make the last part of the pass on turbine only...where it works it's best...instead of a recip only event timed to use the engine thru it's entire operating range.(Redlined tachometer thru the finishline speed traps)...this is where the chassis dynamics become most important for launch,but we have to plan the final drive gearing to use up the motor at the end of the pass...I will not get into chassis dynamics here,as there are many physics aspects that come into play the first instant the whole event occurs,mostly traction issues as Newtonian laws apply to racing a wheel driven motor vehicle.

if using a turbine drive axle,I now wonder if right side drive axle life caused by the recip driveshaft rotation reaction could be diminished by the drive input of the turbine drive rotating inertia in the opposite direction on the rear side of the final drive hypoid ring gear in the rear end...any thoughts on this?
 
this is a 40th anniversary celebration of my car. My car has quad head lights for the export market.

They did own Maserati for a while that was when the Bora and Merak was in production. as part of the deal Citroen made the SM.

 
I always liked Citroens as they seem to always retain some aspect of their body style throughout the years.They don't change to the point you can't recognize them.

Front-wheel drive, rear wheel well covers.

I remember those cars. There was a guy in the town I lived when I was a kid that had one. I always thought it was an interesting car. I looked unlike any other car I had seen, except for a BMW Isetta that another fellow owned. For some reason that car used to make me laugh when I'd see it. It reminded me of a clown car or something. Still, I wish I had one today.

Yeah the BMW Isetta was pretty funky. Reminded me of the Messerschmitt KR200: :p

Back to the "three-wheelers".

So the real question is this. Was this a restoration of sorts, or did the designer just hate the Honda Del Sol ?

Or was he looking for a weight saving:)

I liked the old side cars:) I myself am not that much into bikes, but know others might like them
