The project started in 1962 under the lead engineer Vladimir Chelomey, with the first flight planned for 1967. The LK-1 had its origin in several early 1960s spacecraft projects under the generic names of ''kosmoplans'' and ''raketoplans''. In 1965 the project was cancelled in favour of the Soyuz 7K-L1 spacecraft. Further developments came as the LK-700 direct-descent lunar lander program. Configuration The spacecraft consisted of the following modules: * ADU Emergency Engine Unit * VA Capsule The Vozvraschaemyi Apparat (russian: Возвращаемый Аппарат, lit=Return Vehicle, GRAU index 11F74), or VA spacecraft, was a Soviet crew capsule, intended to serve as a crewed launch and reentry vehicle.

''British Trolleybus Systems'', pp. 9, 12. London: Ian Allan Publishing. .or trolleyDunbar, Charles S. (1967). ''Buses, Trolleys & Trams''. Paul Hamlyn Ltd. (UK). Republished 2004 with or 9780753709702.) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded trolley poles. Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole (or pantograph). They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600- volt direct current, but there are exceptions. Currently, around 300 trolleybus systems are in operation, in cities and towns in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
