astern turbine meaning in Hindi

Examples

1. The old steam engines required astern turbines to move the ship backwards or stop her moving forward.
2. Astern turbines operated on the two wing shafts, with the central shaft idling when the ship was backing.
3. Since ships are rarely operated in reverse, efficiency is not a priority in astern turbines, so only a few stages are used to save cost.
4. An astern turbine was incorporated in the exhaust casing of the low-pressure turbine, and a cruising turbine was coupled directly to the high-pressure turbine.
5. The main high-pressure turbine drove the centre shaft, with the outer shafts being fitted with low-pressure turbines, together with cruise and astern turbines.
6. The guardian valve must be opened prior to any maneuvering situation, in order to permit the astern turbine to be used to bring the vessel to a rapid stop or to back down.
7. The two inboard shafts were driven by the high pressure ahead and astern turbines with the ahead turbines having an extra stage for cruising; this was separated from the main turbine by a bypass valve.
8. A "'guardian valve "'is a valve used in marine steam turbine propulsion plants to prevent steam from leaking into the astern turbine while the vessel is operating in the ahead mode.
9. Each set consisted of a high-pressure ahead and astern turbine driving an outboard shaft, and a low-pressure ahead and astern turbine driving an inner shaft . A cruising turbine was also coupled to each inner shaft, although these were not used often and were eventually disconnected.
10. Each set consisted of a high-pressure ahead and astern turbine driving an outboard shaft, and a low-pressure ahead and astern turbine driving an inner shaft . A cruising turbine was also coupled to each inner shaft, although these were not used often and were eventually disconnected.
