A propeller is a type of fan which transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and air or water is accelerated behind the blade. Propeller dynamics can be modeled by both Bernoulli's principle and Newton's third law. From Wikipedia under the

Q. I'm referring to a Continental Airlines airplane. I just image googled it and it shows mostly jet engines. However one pic(1st page) shows a high wing with props. Thanks. Asked by eventhorizonbm - Sun Jul 27 16:31:57 2008 - - 6 Answers - 0 Comments A. It has one, attached to the emergency deployable RAT (Ram Air Turbine), essentially a windmill that would deploy from a compartment on the right side of the aircraft nose, to provide electrical power for the systems if the engines were to fail. A high wing aircraft with props is most likely a Dash8 (later renamed Q's) from the deHavilland company (which was bought and amalgamated with the Canadair company--along with Short Brothers and LearJet to form Bombardier Aerospace). The nose of the Dash8 is not totally dissimilar from that of the Challenger business aircraft (and therefore to the various CRJ's) but when those aircraft were designed, they were not part of the same company so the resemblance is coincidental. Since Continental also… [cont.] Answered by Vincent G - Sun Jul 27 18:15:37 2008 From Yahoo Answer Search: "Propellers"
