ASP - TurboSupercharging Video

Covers turbo and supercharging for the AVS-167 class.
I made this video as part of a class in the Portland Community College's Aviation Science professional pilot program. It's a two-year program that helps people start their pilot careers. If you're interested, you can visit our website at www.pcc.edu/fly

Very good video! I'm a student mechanic and I believe that "Normally, when RPM is decreased, MAP increases due to less demand for air by the cylinders" is not quite right. If we are talking about a plane with a constant variable pitch propeller, a decrease in RPM (by increasing the propeller blade-angle by manually adjusting prop lever) will put a higher load on the engine, thus slowing down the RPM of the engine. This causes there to be less vacuum developed by the intake strokes. So, the engine is producing less vacuum... and this also means the air pressure in the manifold will increase. If we are talking about a fixed pitch propeller, a decrease in rpm ( by closing the throttle) will typically cause the manifold pressure to decrease because more of the vacuum created by the intake strokes is kept/stored in the intake manifold because the throttle butterfly is more closed. If we are in a fixed pitch propeller plane and rpm is decreased by climbing the airplane, the manifold pressure will go up (throttle butterfly stays the same but rpm decreases and thus less vacuum is developed). I hope I'm not missing something... but I think this is right. Very good video.

Im not even half way through this video and I want to say thanks...already..If schools would show these up dated videos instead of the BS they have us watch from the 1980's to understand this concept, paying for school would be worth it..20 minute video cleared up a 3 month confusion and teachers making up BS to sound intelligent...Im pissed about the time wasted and glad I found this video....I feel better now...lets continue....lol

Really great explanations! Clear and simple to understand. Thanks for sharing the knowledge.
Also what textbook are you referring to in your videos?
