Tom Finch's Induction into the Texas Science Summit Hall of Fame

The Inventor, Tom Finch, puts thousands of miles every year on his own Honda motorcycle, so he knows first-hand what a motorcyclist needs for comfort and safety.

Milestones in our quest for Aerodynamic Excellence

Aerodynamic Drag is an elusive enemy of efficiency and performance in over-the-road vehicles. For those who may think this an insignificant subject, we would like to advance these comments for your consideration.

There is only one thing that keeps your motorcycle from going faster than it can, and that is Aerodynamic Drag.

There is only one thing that prevents your motorcycle from passing a truck in a shorter time, and that is Aerodynamic Drag. If you worsen the Aerodynamic drag by using a high drag trailer, you will be giving up considerable highway passing performance.

If there is the slightest doubt in your mind about these statements, the next time there is a 20 or 25 mph wind blowing, find a level road that is aligned exactly with the wind. Make a run at 50 mph into the wind and accelerate as quickly as possible into the wind until you reach 70 mph and time that acceleration. Now turn the bike around and do the same thing with the wind at your back. The difference in acceleration times will be very large, indicating that it was the Aerodynamic Drag of a difference of 40 mph wind speed that you are measuring. You will tell yourself that the tail wind is pushing you. This is not true, however, and can only be true if the wind speed was faster than you are going, (at least 50 mph in this example.) What you are actually experiencing is the reduction in drag associated with your reduced air speed. To illustrate how important this is, we have included some photographs of Aerodynamic Work accomplished by the XTc Trailer designer, Tom Finch.

In the two photos of the UPS 727 QF air freighters, certain features can be seen. The center engine inlet above the fuselage is obviously not Boeing. The UPS fleet of 727-100 air freighters were converted to Rolls Royce power and Tom Finch was the head of project at The Dee Howard Company. The center engine duct was changed in aerodynamic profile and patented by Tom and produced enough low distortion air at the face of the engine to produce adequate thrust. Other aerodynamic changes are visible in the close up of the aft end of the aircraft. These changes reduced the drag of the aircraft by 18 counts, allowing the completed aircraft to carry sufficient fuel and load, even though the new fuel efficient and very quiet Rolls Royce engines produced much less cruise thrust than those they replaced. The result was a very efficient aircraft that used much less fuel and could fly into and out of airports at night.

The 24 series Learjet was known to have 1250 NM range at its most fuel efficient speed of 0.72 Mach. After Tom Finch developed and patented a major aerodynamic change to the model 24 Learjet, it had a range of 1800 NM at its new most efficient speed of 0.79M. The change was called the Learjet XR.

The Tefco Streamliner aluminum camper trailer was developed in 1963, when 600 CC engines were considered large, by Tom Finch and had vastly superior drag reduction over other trailers of its day and still does today in the Camper Trailer class.

Finally, the new XTc Trailer by Tom Finch has his signature aerodynamic shape that results in low drag coefficients seen only in aircraft. To prove the low drag level, this XTc trailer was pulled in a zig-zag course in the twisties of the Texas Hill Country at an indicated speed when possible of 55 mph (51.4 true). The result was an indicated 300.3 mile run at a GPS average of 49.6 mph, on one tank of fuel, rarely matched by any Gold Wing, even without a trailer.
