On automobiles, disc brakes are often located within the wheel A drilled motorcycle brake disc. The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. [4]
Schematic water brake on a dynamometer A 4-minute ‘how-it-works video’ tutorial explaining how engine-dynamometer water-brake absorbers work.. A water brake is a type of fluid coupling used to absorb mechanical energy and usually consists of a turbine or propeller mounted in an enclosure filled with water.
The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion. "The idea worked, but the propulsion force generated was less than the motor would have generated if it had been connected to a ...
Diagram of retractable fin stabilizers on a ship. Ship stabilizers: a fixed fin stabilizer (foreground centre) and bilge keels (left background).. Ship stabilizers (or stabilisers) are fins or rotors mounted beneath the waterline and emerging laterally from the hull to reduce a ship's roll due to wind or waves.
The Buckau, the first vehicle to be propelled by a Flettner rotor. A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow.

The first such ship to use the Voith Schneider propeller was the excursion boat Kempten. Two German 1935-type M class minesweepers M-1 and M-2 were fitted with VSPs. The first British ship to use Voith Schneider propellers was the double-ended Isle of Wight ferry MV Lymington , launched in 1938.
A Soviet Ka-32 helicopter with coaxial contra-rotating rotors, in 1989. Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque.
E-Ship 1 at Cassens-Werft shipyard E-Ship 1 with Flettner rotors mounted. The hull of E-Ship 1 was built by German shipbuilder Lindenau Werft in Kiel. The ship's launch took place on 2 August 2008, with the delivery date estimated for the first half of 2009. In September 2008, [2] Lindenau-Werft declared insolvency.
