Contra racing designs and builds counter rotating propeller drives for descriminating model airplane racers. Contra-rotating propellers should not be confused with counter-rotating propellers—airscrews on separate shafts turning in opposite directions operation when airspeed is low, the mass of the air flowing through the propeller disk causes a significant amount of tangential or rotational air flow to be created by the spinning blades. With concern that the contra-rotating propellers would not be available on time, the xp-60b was modified to take the r-2800-10 engine driving a four-bladed propeller. By the mid-1940s the limitations of piston aero engines were becoming apparent every possible scheme to squeeze the last bit of power from the internal combustion engine was tried one of the most successful innovations was the contra-rotating propeller arrangement whereby two sets of propellers driven by one engine and sharing a. 3 design and cavitation performance of contra-rotating propellers by dimitrios laskos submitted to the department of mechanical engineering on may 5, 2010.

With the climate in the shipping industry as competitive as ever, the shipowners look favorably on any breakthrough that could lead to cutting shipping costs that is why japan marine united corporation’s (jmu) innovative fuel-saving contra rotating propeller system (crp) has made waves within. Contra-rotating propellers the feature that really sets the electroflight p1e apart from other electric aircraft is its use of contra-rotating propellers this is an innovative development to combine the best of the past aircraft technologies with the. Contra-rotating propellers involves placing a second propeller rotating in the opposite direction counter rotating props.

Contra-rotating propellers are used on torpedos due to the natural torque compensation it is also used in some motor boats the cost of boring out the outer shafts and problems of mounting the inner shaft bearings are not worth pursuing in case of normal ships. Contra rotating props combined with turbo-prop potential of my coaxial drive that same year and it was an exiting experience to have it installed in his sebart. The do-335 used counter-rotating propellers but not in the way that the russian bear bomber does (contra-rotating i believe has been stated here. The main advantage of contra-rotating props is the increased efficiency (6 to 16% according to wikipedia) another advantage is that the torque is pretty much cancelled out by the contra-rotating prop, but this is much less of an issue in aircraft with an engine configuration like the tu-95 in your post.
