Propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk) is the term for a propeller's tendency to rotate about a vertical axis (also known as yaw motion). The rotation is in addition to the forward or backward acceleration.
Accuride was founded in 1986 in order to acquire the wheel-making division of Firestone Tire & Rubber Company. [1] The purchase was orchestrated by Bain Capital under the direction of Mitt Romney . With Bain Capital as its new owners, Accuride revamped production and restructured executive pay, quickly boosting the company's profitability. [ 2 ]
Motor Wheel moved into making steel wheels in the 1920s and brake drums in the 1930s. [2] In 1961, Motor Wheel moved its headquarters to another facility, and demolished many of the buildings on the old site. Motor Wheel became a subsidiary of Goodyear Tire and Rubber Company in 1964, but left Lansing entirely in 1996. [2]
A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
Most other propeller-driven ships will reverse the direction the prop spins. For a paddle wheel ship, reversing the direction of the paddle will provide astern propulsion. Redirecting the thrust of a water jet driven craft, changing the cyclic pitch of a Voith-Schneider propulsor, or rotating an azimuth thruster 180 degrees has the same effect.
A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is ...

The wheels are fastened to the hub by means of a winged, threaded nut, called a "knock-off" or "spinner." Usually, this will feature right-hand threads on the left side of the vehicle, and left-hand threads (rotate clockwise to remove) on the vehicle's right side so the screw-on spinner would stay tightened as the auto was in forward motion.
