Bell XV-15
The Bell XV-15 is an American tiltrotor VTOL aircraft. It was the second successful experimental tiltrotor aircraft and the first to demonstrate the concept's high speed performance relative to conventional helicopters. Development Early VTOL rotor aircraft The idea of building VTOL aircraft using helicopter-like rotors at the wingtips originated in the 1930s. The first design resembling modern tiltrotors was patented by George Lehberger in May 1930, but he did not develop the concept further. In World War II, a German prototype called the Focke-Achgelis Fa 269 was developed starting in 1942, but it never flew. Two prototypes that made it to flight were the one-seat Transcendental Model 1-G and two-seat Transcendental Model 2, both powered by single reciprocating engines. Development started on the Model 1-G in 1947, and it flew in 1954. The Model 1-G flew until a crash in Chesapeake Bay on 20 July 1955, destroying the prototype aircraft but not seriously injuring the pilot. ...

DR Class V 15
DR class V 15 and DR class V 23 were diesel locomotives of Deutsche Reichsbahn (East Germany), Deutsche Reichsbahn in the GDR with side-rod drive for light shunting (rail), shunting duties. History In order to cover losses incurred during World War II, Deutsche Reichsbahn had some additional ''DRG Kleinlokomotive Class II, Kleinlokomotiven'' built in the early 1950s. However, a more powerful light shunting locomotive with an engine power of 150 ... 180 PS (110 ... 132 kW) was required to replace the aging ''Kleinlokomotiven'' and the steam locomotives used for similar duties. In 1956, LKM Babelsberg presented the new type V 10 B with mechanical gear and a engine with wheels of diameter, based upon the concept of the Kö, but with a higher and closed cab for use on industrial railways and sidings. As this class did not quite satisfy the demands of DR, class V 15 was developed from it. This new class was equipped with hydraulic gears of type GSR 12/3,7 (single torque convert ...
