      • ‘At intervals, the ATV will also use its thrusters to boost the Station's altitude.’
      • ‘It will rotate gradually by about 180 degrees, over 10 minutes, so that the thrusters are pointed in the same direction that the spacecraft is moving.’
      • ‘The long-lived spacecraft keeps itself pointed correctly by firing small thrusters fueled by hydrazine gas.’
      • ‘On the way down it will take images that will help determine its exact location and altitude, and set the timing for the final thruster firings.’
      • ‘Proper lateral guidance, or guidance around the cylinder, is ensured by small rockets called thrusters.’
      • ‘After that, the main thruster will give the spacecraft a push in the new direction.’
      • ‘They used the thrusters, over several months, to nudge the satellite into a geosynchronous Earth orbit.’
      • ‘Some of the mines move using rocket thrusters, others use a hopping mechanism and hold enough fuel to make 100 leaps.’
      • ‘The Busek Company will provide a set of miniature ion thrusters capable of controlling spacecraft position with extremely fine precision.’
      • ‘These thrusters allowed the spacecraft to modify their orbits with less propellant than is the case with chemical engines.’
      • ‘Using small thrusters, the spacecraft will rotate so that the solar panels are oriented perpendicular to the Sun.’
      • ‘After one and a half orbits the Saturn thrusters fired and the astronauts began their odyssey.’
      • ‘SMART - 1 will then use its thruster to reduce the altitude and eccentricity of this orbit.’
      • ‘Other features, such as a telescope and finely tuned thrusters, enable the spacecraft to stay exactly oriented on a distant star.’
      • ‘This raised the possibility that Russian rocket thrusters would be needed to fire much more frequently, depleting their limited supply of propellant.’
      • ‘But ion thrusters and ordinary rocket engines part ways in their choice of propellant and their source of the energy that accelerates it.’
      • ‘Another application is analysis of plume impingement, the effects of firing of thrusters by one spacecraft on another spacecraft nearby.’
    2. 1.2 A secondary jet or propeller on a ship or offshore rig, used for accurate manoeuvring and maintenance of position.
      • ‘The sister ships are also powered by an all-electric propulsion system which includes 360 degree podded thrusters - a first for a Royal Navy ship.’
      • ‘The vessel is of a round hull design with a bulbous bow, bow thruster and propellor nozzle.’
      • ‘The superstructure of the ferry ‘Norse Viking’ started to vibrate gently as below the engines and thrusters of the huge ship began to drive her into reverse and alongside the berth.’
      • ‘The ship has two retractable thrusters for manoeuvring and position keeping.’
      • ‘The two LIPS Z drive azimuth thrusters are fitted with fixed-pitch reversing propellers.’
      • ‘Azimuthal thrusters and a dynamic positioning system are fitted for holding the position and heading steady during operations involving embarking or disembarking landing craft.’
      • ‘It has twelve computer-operated thrusters which enable the ship to maintain position to within 1 m even in heavy seas.’
      • ‘A retractable azimuth thruster is capable of propelling the ship at 10 knots.’
      • ‘The vessel could be manoeuvred with its bow thrusters to bring the stern ramp very close to the two men to whom life belts and/or ropes were thrown.’

    3. 1.3 A surfboard or sailboard capable of increased speed and manoeuvrability.
      • ‘There are a few surfers out on mals, bodyboards, and thrusters, but there's plenty of room for all.’
      • ‘Debates range from tow-in versus paddle in and thruster versus single fin all the way down to which local spot hosts the worthiest crew.’
      • ‘What about thrusters… you weren't a fan of them when they came out.’
