In UAV terms, the Hunter UAV is an oddity, in that it uses both pusher and puller props, though this is somewhat unusual. Jun 3, 2011 #1. ... (concave) of a prop fan faces air flow or direction. Cavitation Characteristics of Some Pushing and Pulling Podded Propellers. In a pusher configuration, the force provided by the propeller is pushing towards the engine, rather than away. At a high level, what are the differences in […] If you've got two fans and can install them both as pullers then that's the way to go. Each layout has its advantages and disadvantages and as with all design choices selecting one or the other is dependent on the underlying design goals. While pure pushers decreased in popularity during the First World War, the push-pull configuration has continued to be used. Since electric motors can spin either way you can put a so called "pusher" prop on the front of the plane, or a so called "puller" prop on the back of the plane. At a high level, what are the differences in […] Kevin Jonker Well-Known ... One fan can't be both a "pusher" and a "puller" in reference to moving outside air through the radiator. If you are designing and building a plane and had the option of either a puller or pusher propeller, is there any difference between the two? By Russ and Tiña De Maris A reader asks us, “What’s the difference between a diesel pusher and a motorhome with the diesel engine up front?” Here are some thoughts from RVers on the subject — and you may have a few of your own to share: Noise: Many RVers say that a FRED […] By Russ and Tiña De Maris A reader asks us, “What’s the difference between a diesel pusher and a motorhome with the diesel engine up front?” Here are some thoughts from RVers on the subject — and you may have a few of your own to share: Noise: Many RVers say that a FRED […] Pusher prop Vs tractor prop There's a debate on another aviation (model) forum about which is more efficient, a tractor-type or pusher-type prop arrangement. Derived terms * paper-pusher * pen-pusher * pencil-pusher See also In contrast, both the World War II-era Dornier Do 335 and the early 1960s-designed French Moynet M 360 Jupiter experimental private plane had their pusher propeller behind the tail. Pusher is a see also of tractor. There have, of course, been oddities in each category, such as the B-36 Peacemaker, which used pusher props. Don't forget that the prop is not there on its own, it is connected to the powerplant, which is a major heavy item, and setting it's location has a big effect on CG, stability, handling, etc. In context|aviation|lang=en terms the difference between pusher and tractor is that pusher is (aviation) (aircraft configuration) an aircraft with the propeller behind the fuselage while tractor is (aviation) (aircraft configuration) an airplane where the propeller is located in front of the fuselage. All things being equal, (fuse & wing aero drag, engine & prop efficiency, etc) which is going to make for a faster aircraft? Tractor is a see also of pusher.
