driving propeller

As with the previous designs, these were to be housed inside the fuselage, driving propellers by long driveshafts.

In 1915 Reed experimented with metal propellers using a 10hp electric engine driving propellers up to 19,000rpm.

The remaining strands of the cable unravelled and snapped under the fierce drag of the submerged barge and the this's driving propeller.

A steamboat, sometimes called a steamer, is a ship in which the primary method of propulsion is steam power, typically driving propellers or paddlewheels.

If scramjets work as engineers predict, proponents say, it could bring an advance in aircraft propulsion equal to that of jet engines over motors driving propellers.

Anton Flettner was an early rotary-wing pioneer in Germany, he developed a torqueless rotor by powering it with small engines fixed directly to the blades driving propellers.

Major Siebel proposed giving the unpowered Type A barges their own motive power by installing a pair of 600 hp surplus BMW aircraft engines on them driving propellers.

Multi-plane, later cruciform, tail surfaces were used for control and stability, and two engine/crew cars hung beneath the hull driving propellers attached to the sides of the frame by means of long drive shafts.

In these installations, the engines are either mounted in nacelles or the fuselage on tailless aircraft, or buried in the wing on flying wings, driving propellers behind the trailing edge of the wing, often by extension shaft.

This large aircraft was to carry a heavy cannon armament including a turret in the rear of the fuselage nacelle, which also housed the single engine, driving propellers in the nose of each tail-boom, through shafts and gearboxes.

The early Swings were powered by either 60 kW (80 hp) Rotax 912 UL flat-four engine or the two-stroke twin-cylinder 49 kW (65 hp) Rotax 582 UL, driving propellers with two or more blades.

During the early 1940s, Douglas Aircraft Corporation developed a configuration for high-performance twin-engined aircraft, in which the engines were buried in the fuselage, driving propellers mounted behind a conventional tailplane, in order to reduce drag by eliminating drag inducing objects such as engines from the wing.
