Introduction To Advanced Aerodynamics

By Professor DLG'er
In todays lesson, we are going to use a blistering hot day and our vehicles for our learning experience.

Imagine yourself driving down the road on a very hot sunny day.  It must be 90 degrees inside your vehicle.  Either your vehicle doesn't have A/C, or the A/C is broken.  What do you do?  Do the following:

• Roll your driver side window down all the way
• Rest your forearm on the door, with your hand pointing forward
• Cup your hand (palm up) and lower your arm slowly 
• Once your hand drops below the mirror, you should feel a blast of air
• With trial & error, you should be able to direct the blast of air up your arm and to your body
• Palm below the mirror worked for me, you might have to try above the mirror

Once you can successfully direct the blast of air to your body, you have passed the 'Introduction To Advanced Aerodynamics' class!
