The engine is a General Electric Model T58-8F. This is a helicopter turboshaft engine that was converted to a jet by some internal modifications and a custom tailpipe. The engine spins up to 26,000 RPM (idle is 13,000 RPM), draws air at 11,000 CFM, and is rated at 1350 hp. It weighs only 300 lbm. It grows as it warms up so the engine mounts have to account for this. The mounts in the front are rubber and the back are sliding mounts on rubber. The structure holding the engine was designed using finite element analysis and is redundant. Strong, damage tolerant, and light. Second battery and fuse/relay panel on the right, halon fire system and 5 gallon dry sump tank on left. 24V starter motor is in the nose of the engine. 700 A of current goes into that motor for 20 seconds during start-up. Due to heat, must limit starts to three in one hour. Big screen is to avoid FOD (foreign object damage). Jet keeps sucking the rose out of the bud vase on the dash!
A lot of attention to details in the car. Note the aluminum block holding/protecting the halon gas line, pull line, harness to engine, and oil pressure line. Rectangular tank under inlet screen is for various fuel drains. Note temperature gauge and shutoff valve for dry sump tank. 3 gallons of turbine oil at $25/quart (ouch!). Two-stage PPG paint matching exterior of car was used inside the car. It is not easy to paint around a lot of bars, etc while crouched in a car, in your dus ty home garage, avoiding drips, and with your wife screaming that the fumes will cause brain damage in the kids. Especially with two-stage where you have multiple coats and critical drying times. Kids passed their grades so I guess damage was minimal, but more importantly, the paint turned out great!
Street racing action. The other guy wimped out after a few "big-fire" demonstrations. What you see in the picture is about one-twentieth the full size of the fireball. Guy standing beside car had never seen it run before and was smiling ear-to-ear throughout the show. Had I launched, I would have burned him t o a crisp. Well, live and learn.
We get this a lot. A police officer picking at his nose while trying to figure out what to charge me with. Notice the hopeful anticipation of us on the right. We're rooting for him and offer suggestions but unfortunately, the California Department of Motor Vehicles did not anticipate such a vehicle so he's out of luck. Hmmm, the car has two engines making the car a hybrid so maybe we can drive in the commuter lanes along with the Toyota Priuses.
The car was built in this garage. Paint, welding, everything except some mill work. That's me standing beside the engine that is out of the car for some fuel controller work. The orange line is for the afterburner. There's one on the other side too. Here you can make out the four rows of variable inlets/stators at the front of the engine. Their angle changes with engine speed and is used to avoid compressor stall. There are 11 compressor stages and 2 turbine stages. The engine's pressure ratio is 8.3:1. That's how you work on a jet engine. Stick it on its end. Easy to store them that way too.
Here's my wife's Honda Metropolitan scooter. She wants it to go faster than 40 mph. So I have these two little JFS 100 jet engines and I am thinking how to put them on the scooter. Engines are 50 lbm each so weight is an issue. Will probably use air-start with a carbon fiber tank of compressed air. That saves weight since batteries will then not be needed.
Looks cool from the top. Will want to make aluminum housings to go over the engines just like on a DC-9.
*****in' from the back too. Should get the scooter going. On one jet engine alone, this engine will get a kart up to 60 mph. Looks like I have a lot of spare wire left over from the Beetle job to do the scooter.
