Which of the following most accurately describes the problem?

A teardrop is the most efficient aerodymic shape in overcoming air resistance.

A box is the most efficient shape for uling cargo.

The drawback to the flat-fronted tractor d trailer box shape is that they punch into air; churning it and increasing air drag her than parting it smoothly.

r costs you money In fact, this churning air can effectively d about another 3' in height and 6' in width the actual dimensions of the haulage rig. :Teased air drag that further increases fuel asumption.

The faster you go the more air drag multies and the more fuel is used solely to ercome it.

As an example, at 58 mph more horsewer is used to overcome air drag than in lling the load. (See the air drag chart for )ical large tractor-trailer combinations.) An answer from outer space Yet, with a simple modification air d can be cut by around 20%.

The result is a major increase in miles gallon. And lower operating costs. The fuel saver is called the Uniroyal Deflector. It does just what the name impl With the Air Deflect(); instead of cab trailer fighting air-buffeting the air stream fl smoothly around and over the top of the Although the Air Deflector is simplc appearance, the geometry is the result serious study. c=m+ Uniroyal's aerodynamic specialists w the same team who developed streamlin solutions for American rockets.

The American experience, 22% fuel savii In North America where road haul; conditions range from arctic tundra to des( and sub-tropics, use of the Uniroyal Deflector is growing dramatically week by w( Fleet operators report fuel savings ra ing from 9% to 22%.

Every single operator, whatever his t! of fleet or operating conditions, has reali! a saving. Just consider these five randomly selected :king lines:

Also, we'll tell you at what point the Air flector should have paid for itself. After it's plain savings all the way.

iiroyal versus other air :flectors There are other air deflectors ailable. But all pall into insigficance beside Uniroyal's.

First, its aerodynamic ape set-up are right for vary cab and trailer combos being e result of highly sophistited aerodynamic knowledge.

Only the Uniroyal Air .3;flector has a variable angle. It can be set for both the height difference and the between cab and trailet This results in the mc suitable angle of profile for smooth airflo It is very strong, being hot moulded gla fibre-not cold, hand lay-up. (Deflectors me very high stresses and it wouldn't do to sh( one on the motorway.) Fixtures and fittings are designed to a just to the differences of spe cific cab s.

The Uniroyal installation engineer se the slope-profile according to the specific c: and trailer and then the deflector bolts on wi 8 securing bolts. Simple at that.

He'll also leave you a simple deflector an calculating chart for resetting the deflect should cab and trailer combos change.
