These effects are of the same order of magnitude as the propulsive efficiency change due to forward movement of the transition point behind the tractor propeller, and should be included in any comparison of the efficiencies of the two types'. The pusher propeller gives almost the same increase ...
An airscrew or propeller located in front of the engine, which pulls the airplane. It is unlike the “pusher propeller,” which is located in the rear of the wing and pushes the airplane. The tractor propeller “pulls” the airplane through the air, and the thrust bearings in the engine...

A wing of 5-foot chord was fitted with a propeller drive assembly providing for several axial locations of tractor propellers and pusher propellers. A three-blade 4-foot propeller and a three-blade 3 1/2-foot propeller of special design were tested in this wing with spinners and fairings ...

PusherThe purpose of this study is to compare the aerodynamic characteristics of the wing when the propeller is placed in different positions, namely in the conventional, tip-mounted tractor, and pusher configurations. Numerical studies were carried out by solving steady RANS equations in the flow ...
KP-505 propeller as the research object, hydrodynamic open-water characteristics of this propeller was first calculated, and agreed well with test results. Then, numerical simulation of the thrust, torque and efficiency of the three types of the AZIPOD systems (Pusher, Tractor and Schottel) with ...
