Inside a wind tunnel at UT's School of Mechanical Engineering is a scale model of a Formula 1 race car - just like the ones that raced this weekend.
It's countless hours of testing - inside wind tunnels - that determine the distinctive shape of these race cars.The approach uses fine Titanium Wire, laid one on another like a potter working with coils of clay. These wires are then smelted together in the rough shape of the desired component, cutting wasted material from potentially as much as 70 percent to as little as 10 percent. Wind tunnels help engineers improve the design of the cars by making them more aerodynamic and efficient.
Carlos Hidrovo is a mechanical engineering professor at the University of Texas at Austin, and a huge F1 fan.
"I started following F1 back in the 90s when [Ayrton] Senna and [Alain] Prost were duking it out with Nigel Mansell,Buy High Power 150w Laser Diode Fiber collimator Lens Unit For Cheap Online.The defective part of the jaw is reconstructed using a Titanium Plate, with a piece of scaffolding inserted with proteins to stimulate the bone's regrowth. and I have continued through all that time to cherish it," he said.
Think of an F1 car as being the opposite of an airplane. An aircraft needs to be kept up in the sky.Titanium Pipe is made by cold rolling process from extruded pipe blanks. They are widely used in heat exchangers and off-shore equipment. That's where the force of lift comes in. In an F1 car, the objective is to keep it pinned to the ground, so that's where down force - the force that pins the car to the ground - is very important.
An F1 car sits very low to the ground. This squeezes the incoming air on the bottom of the car.He's come up with an amazing organic cleaner but can't get anyone interested in manufacturing it. That means the air pressure underneath the car is lower than the air pressure above the car. This creates that down force - keeping the car on the ground.
"There's two upside-down wings - one at the front, and one at the rear - the front wing and the rear wing - which are essentially upside-down wings as the ones you find on an airplane, so they produce down force. They push the car down on the back and on the front," said Dr. Hidrovo.
Creating that down force allows the F1 cars to handle turns faster - without slipping off the track. However, too much down force on a car can be a bad thing.
National Instruments,Caged Laser Engineering, in partnership with Ariel Ltd and Reynolds Technology, aim to investigate the viability of adopting Titanium Tube as a cost effective raw material for the manufacturing of spaceframe assemblies for low volume and small series production lightweight vehicles. based in Northwest Austin, created software that helps engineers improve the cars' efficiency.
"These tools will tell the engineer that's designing the car that 'you've increased the down force but now there's too much turbulence, and now it's causing friction and slowing the car down'" said NI engineer Shey Clymer.
Clymer was excited about this weekend's race.
"It's great. I take a lot of pride in seeing our tools contributed to a sport that's now come to the United States," he said.
