  • What makes a constant speed prop different from a fixed pitch prop, and what are the operational differences between airplanes with the two?

  • Some aircraft have pusher type propellers. In what ways is it different from a tractor type propeller? What's are the advantages and disadvantages over a tractor type.

  • Turbine engines are covered, which of course is to contain the process (just like a super/turbocharged engine is as soon as the air enters the intake). But it got me thinking, doesn't this also reduce...

  • My explanation of how a constant speed propeller works has always been a little shaky. I know about the "speeder spring," "counter-weights," and how it utilizes the engine oil pressure, but I'd love to know of a simple and easy-to-understand diagram and explanation that I can use to really understand it, and then teach it to others?

  • Jet engines are by their very nature push-engines, however, most propeller airplanes use pull-engines. Is there an inherent advantage to using pull-propellers except for the increased airflow over the fuselage and tail (with its rudder and elevator)? Twins generally have their engines on the wings, and the tail is no longer directly behind it, does that mean the choice of a pull-engine... powered parachutes where you simply don't want a propeller in your face The Convair B36 is one notable multi-engine aircraft with engines in pusher configuration, as is the Piaggio Avanti. Single engine

  • In regards to flying at higher altitudes, does it matter if you have a turboprop in comparison to a piston engine powered engine driving a propeller?

  • I read that a three blade can improve climb performance and decrease noise. How does that work?

  • Airplanes with propellers were invented a long time ago. After that, jet engines came into existence. My question is: why do we still have propeller engines? The reasons I can think of are: They are cheaper; They cannot achieve very high speed; They are not very noisy (though not always). Besides these, are there any other reasons general aviation airplanes built nowadays don't have jet engines?

  • I've seen on numerous different constant-speed propeller aircraft and different pilots using different RPMs during the cruise phase on a propeller aircraft. What dictates the RPM used during normal cruise operations, and why is that the case? Often there are multiple possible throttle/RPM combinations that deliver the same power, so where would you pick one or the other?

  • An aviation expert reminded me that a propeller is a wing. While I understand that propellers use similar principles to generate force, it muddied the definition of a rotary wing aircraft vs a fixed wing aircraft. If the propeller of a fixed wing aircraft is considered a wing, what is the distinction between the two? Is it how much surface area each type of wing works on? Is it the direction of force?

  • I was watching the Disney movie Planes with my younger brother, and one of the characters/planes perform a emergencial landing on an aircraft carrier. And that got me thinking... In case of emergency, is it possible (doable) to land a small propeller-driven aircrafts, like a Cessna 350 Corvalis on a military aircraft carrier?
