The vessel is powered by two W�rtsil?8L45D diesel engines which drives two variable pitch propellers.
2.
In 1935 the 12Ner variant was fitted with an in-flight-electrically operated variable pitch propeller.
3.
There, early in 1934, it was contributing to long running tests of Ratier variable pitch propellers.
4.
Well, generally, they DO have variable pitch propellers-and that's a form of gearbox.
5.
The engine is 73.5 kW ( 98.6 hp ) Rotax 912S flat-four, driving a variable pitch propeller.
6.
A metal, variable pitch propeller improved the take-off performance and the Maillet 21 was expected to clear a obstacle from the start of its run.
7.
Its, air-cooled, inverted six-cylinder inline Regnier R 6 was in the nose, driving a two blade, variable pitch propeller and with its fuel stored in the fuselage.
8.
*e-Genius, German manned electric airplane, two seated side by side high wing configuration aircraft completely manufactured of fibre composites and equipped with a retractable landing gear, propulsion realized by a permanent magnet synchronous motor with an electrical driven variable pitch propeller.
9.
:A modern propeller driven plane will generally have a variable pitch propeller-and that is ( in effect ) a continuously variable transmission-when the propeller blades are parallel to the circle in which they travel, the blades generate almost zero thrust-as you increase the pitch of the blades, the'gear ratio'gets higher-suitable for flying at higher speeds.
