    • ‘Well, I don't think we should aggravate the woes of the NHS with thousands of Tory thrusters queueing up for speech therapy and gender reassignment.’
    1. 1.1 A small rocket engine on a spacecraft, used to make alterations in its flight path or altitude.
      • ‘Using small thrusters, the spacecraft will rotate so that the solar panels are oriented perpendicular to the Sun.’
      • ‘The long-lived spacecraft keeps itself pointed correctly by firing small thrusters fueled by hydrazine gas.’
      • ‘These thrusters allowed the spacecraft to modify their orbits with less propellant than is the case with chemical engines.’
      • ‘The craft was streamlined, probably capable of atmospheric flight, with twin thrusters to either side of the aft section of the fuselage.’
      • ‘SMART - 1 will then use its thruster to reduce the altitude and eccentricity of this orbit.’
      • ‘This raised the possibility that Russian rocket thrusters would be needed to fire much more frequently, depleting their limited supply of propellant.’
      • ‘At intervals, the ATV will also use its thrusters to boost the Station's altitude.’
      • ‘Other features, such as a telescope and finely tuned thrusters, enable the spacecraft to stay exactly oriented on a distant star.’
      • ‘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.’
      • ‘The Busek Company will provide a set of miniature ion thrusters capable of controlling spacecraft position with extremely fine precision.’
      • ‘They used the thrusters, over several months, to nudge the satellite into a geosynchronous Earth orbit.’
      • ‘But ion thrusters and ordinary rocket engines part ways in their choice of propellant and their source of the energy that accelerates it.’
      • ‘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.’
      • ‘Another application is analysis of plume impingement, the effects of firing of thrusters by one spacecraft on another spacecraft nearby.’
      • ‘The impactor carries four 22 - Newton thrusters, which can fire in pulses varying in length from 0.015 to 0.5 seconds.’
      • ‘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.’
      • ‘After one and a half orbits the Saturn thrusters fired and the astronauts began their odyssey.’
      • ‘This guidance system reads gyroscopes and accelerometers and sends appropriate commands to attitude control thrusters.’
      • ‘Some of the mines move using rocket thrusters, others use a hopping mechanism and hold enough fuel to make 100 leaps.’
    2. 1.2 A secondary jet or propeller on a ship or offshore rig, used for accurate maneuvering 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 thrusters have sufficient power to sustain the ship speed at a constant 6 knots.’
      • ‘The two LIPS Z drive azimuth thrusters are fitted with fixed-pitch reversing propellers.’
      • ‘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.’
      • ‘Azimuthal thrusters and a dynamic positioning system are fitted for holding the position and heading steady during operations involving embarking or disembarking landing craft.’
      • ‘The ship has two retractable thrusters for manoeuvring and position keeping.’
      • ‘It has twelve computer-operated thrusters which enable the ship to maintain position to within 1 m even in heavy seas.’
      • ‘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.’
      • ‘A retractable azimuth thruster is capable of propelling the ship at 10 knots.’
