In another 2022 dive to the wreck, one of Titan's thrusters was accidentally installed backwards and the submersible started spinning in circles when trying to move forward near the sea floor. As documented by the BBC documentary Take Me to Titanic , the issue was bypassed by steering while holding the game controller sideways.
Instead of a tunnel thruster, boats from 30 to 80 feet (9 to 24 m) in length may have an externally mounted bow thruster. As its name suggests, an external bow thruster is attached to the bow , making it suitable for boats where it is impossible or undesirable to install a tunnel thruster, due to hull shape or outfitting.
Propulsion thrusters are those thrusters which provide longitudinal motion for vessels as an alternative to traditional propellers. There are a variety of types of propulsion thrusters but the most common form is the azimuth thruster, that can rotate 360 degrees on a vertical axis to optionally produce thrust for maneuvering. (Lindborg, 1997).
NASA also wanted to analyze how the thruster problems might affect Starliner’s ability to undock and safely back away from the space station. Suni Williams and Butch Wilmore at Space Launch ...
Despite NASA's concerns about earlier thruster problems and multiple helium leaks in the ship's propulsion pressurization system, the Starliner had no problems undocking and moving away from the ...
Williams and Wilmore were then left in limbo by several crucial issues, including gas leaks and thruster problems, that plagued their Starliner capsule during the first leg of its trip. NASA then ...
A "ram" bulbous bow curves upwards from the bottom, and has a "knuckle" if the top is higher than the juncture with the hull—the through-tunnels in the side are bow thrusters. [1] A bulbous bow is a streamlined flaring or protruding bulb at the bow (or front) of a ship just below the waterline.
While just one thruster remains dead in Starliner's current flight, Boeing encountered four thruster problems during the capsule's uncrewed return from space in 2022.
