DON VESCO TURBINATOR
Don Vesco passed away, December 16, 2002 at 2:30 PM in Scripps Mercy hospital in San Diego. Don battled prostate cancer for about a year, but unfortunately the cancer won. The racing world has lost a great competitor and friend.
The power transfer unit
The power transfer units transfer the power from the drive shaft which runs aft from the transmission down the left side of the car to the drive shaft which connects through a universal joint to the pinion gear in the rear end. An almost identical arrangement drives the front end. A 5 inch wide timing belt transfers the power from one pulley to another. Each pulley is supported in bearings mounted on the bulkhead and by bearings mounted inside the pulley on the free end. This arrangement prevents the pulleys from touching as the belt expands, a problem which ended the 1997 Speed Week attempt.
The T55-L-11A SA Gas Turbine Engine
The Turbinator is powered by an Avco Lycoming T55-L-11A SA gas turbine engine. The front of the engine is mounted solid to the frame but the back floats in the longitudinal direction to allow for engine growth from the heat. At the top of the engine is a 28 VDC starter. The transmission mounted on the front of the gas turbine engine. The transmission reduces the turbine output shaft speed to the drive line speed. The gear ratio is currently 2:1 but the transmission can accommodate 1.75:1 and 1.5:1 ratios. The transmission includes three precision machined gears and its own separate oiling system, fed and scavenged by an external dry sump pump. The screened area in the photo is the engine air inlet.

The parachute tubes and drogue ejection mechanism
The parachutes are contained in the two large round tubes, the high speed chute in the top tube and the low speed chute in the bottom tube. The small diameter tube at the top holds the drogue ejection mechanism and two 12 inch drogue chutes, one for each parachute. When the high or low speed chute button on the steering wheel is pushed, the respective drogue is ejected by an electrically actuated spring loaded mechanism. As the ejector mechanism moves to eject the drogue, it pulls a cable that releases the strap that holds in chute in the large tube, thus allowing the drogue to pull out the chute. There is also a mechanical backup for each chute, controlled by cable from the drivers compartment. The mechanism was designed and built by Rick Vesco and perfected by Don.
