VW Beetle Fitted with a Jet Engine

6031769 writes "Ron Patrick has decided to go that little bit further by souping up his VW beetle with a jet engine, as reported by the San Francisco Chronicle. Serious planning went into the project. Patrick said, 'We did (computerized) structural analysis and we did stability analysis. And by God, you know what happens? It works!' Contrast with the Rocket Boy to see how it should not be done." Yes, the Darwin award winner was found to be bogus, but unlike the myth, Ron still lives!

I believe there has been more than one Meteor powered car (I really wouldn't want a full Merlin which would make the jet powered VW look pretty wimpy.) Our R&D people were involved in tractor racing, and one of the competitors had a Merlin powered tractor. We, on the other hand, had a turbocharged Diesel. They came back from one weekend somewhat elated having beaten the Merlin. Apparently the Diesel had been running at 5.8 atmospheres boost - that's about 85PSI.

    So I am afraid this jet car is actually a bit pathetic. It's no more powerful than the (street legal, normally drivable) VW Bugatti, which costs about the same, and it is less powerful than a suitable modded tractor engine.

    What I took away from that company was an in-dept knowledge of how to produce a hardened engine management system, and a lifelong passion for Diesels. As our Technical Director used to say, and history has proved him right, with the exception of power to weight ratio there is absolutely no measure on which a Diesel cannot be made to out-perform every other type of combustion engine.

    Nice project, but the article glosses over a few major problems with this idea:
    • This is a turboshaft engine. That means it puts out its intended power out a shaft, any thrust out the back is just incidental.. But in the VW installation, there's no way to couple this power to the wheels, so the 1,400 horsepower is just wasted.
    • A jet engine's thrust is least efficient at low speeds. Lots of velocity in the exhaust, but that's mostly wasted at anything less than jet plane speeds. The acceleration of this thing is unspecified, but I'd guess not much more than a fraction of a G.
    • Most of these older jet engines take a very looong time to reach 100% power, something like 20-35 seconds. Not suitable for impressive jack-rabbit-like starts. You'd basically have to jam on the brakes, hit the accelerator, and --wait-- 30 seconds for the power to build up. Not very impressive.
    • There's, ahem, a big safety problem for bystanders-- these early engines were not rated to contain their blades if something bad happens. if the engine intake ingests a small rock or loose bolt, the thing could disassemble in a hurry, with white-hot pieces of turbine blades heading out in all directions. Not a healthy environment to be standing around!
    • The rotational momentum of 10 compressor and one power turbine sections is going to be significant, and not in a good way. This car probably needs a very flat aqnd level and straight highway. Any bump is going to cause all kinds of gyroscopic precession around the center and axis of momentum, which is NOT a good thing.

    Trouble is that that kind of engine isn't designed to do that. It's a T-58 engine, a turboshaft engine off of a helicopter. While the engine on a jet is designed to shoot lots of hot air out the back, producing thrust to drive the jet forward, turboshafts are designed to, well, turn a shaft, to turn a rotor blade. In other words, they're torquey, not thrusty, and helicopters don't go fast because of the engine exhaust, they go fast because of the rotor.

    I was looking to buy a (ex-Soviet) MiG 15 or MiG 17 jet engine.

    He'd have been far better off doing that. The engine off a MiG-17 develops 6,000 ft-lbs of thrust.

    I mean, look what kind of performance he gets with his 1500-horsepower jet engine:

    He said that a jet-boosted run will "pin the speedometer and that's at 140." He thinks that when it hits 160 mph -- he hasn't seen that ... yet -

    140? My 300-horsepower Mustang GT is perfectly capable of hitting 140, and would probably do 160 if a governor doesn't kick in. 1500-horsepower is the power of the gas turbine in an M-1 tank; if he had this thing hooked into the drive wheels, he'd go like a bat out of hell. But as it is, all he's doing is making a lot of noise.

He's still got an engine designed to produce a lot of shaft horsepower, and you don't get a lot of thrust out of that just because you remove the shaft.
