In high-speed, light-load robots, such as AUVs, UUVs and submarines, usually the thrusters do not have a nozzle. Propeller guards: Propellers may be damaged by impact from fish or other objects, but may vibrate if the flow to the blades is not uniform. The propeller guard design can affect the flow to the propeller and consequently the performance.
An advantage of turbo-electric transmission is that it allows the combination of high-speed turbines with slow turning propellers or wheels, without requiring a gearbox. It can also provide electricity for other electrical systems, such as lighting, computers, radar, and communications equipment. [citation needed] [26]
Like most Soviet nuclear submarines, Project 705 used a double hull, where the internal hull withstands the pressure and the outer one protects it and provides an optimal hydrodynamic shape. The gracefully curved outer hull and sail were highly streamlined for high submerged speed and maneuverability.
Speed = 1 to 2 kn (1.7 to 3.4 ft/s; 0.5 to 1.0 m/s) vertical, 2 to 3 kn (3.4 to 5.1 ft/s; 1.0 to 1.5 m/s) lateral [2] Hull form configuration has been optimized for vertical travel, as much of the traveling time will be spent ascending and descending through the water column [ 2 ]
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
All boats converted during the GUPPY II program that originally had high-speed drive motors with reduction gears had these replaced with low-speed direct-drive motors, producing 2500 horsepower (1.9 MW) per shaft. The two GUPPY I boats, Odax and Pomodon, were modified to GUPPY II standard.
The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable. The Type 212 is the first fuel cell propulsion system equipped submarine series. [8] [9]
Its predecessor, the Alfa class, could attain short speed bursts of 40–45 knots (74–83 km/h; 46–52 mph) while submerged. [4] [5] There are also claims that the Soviet twin-propeller submarine K-222, with titanium inner and outer hulls, reached 44.7 knots (83 km/h; 51 mph), fully submerged, during sea trials in 1969.
