auxiliary propulsion system造句

• These auxiliary propulsion systems also enable the submersibles to move sideways.
• The HAPS ( Hydrazine Auxiliary Propulsion System ) is powered by three restartable, monopropellant hydrazine thrusters.
• The auxiliary propulsion system provides complete attitude control during coast flight of the S-IUB / IU stage.
• In the S-IVB third stage, there was an Auxiliary Propulsion System that also had ullage functions.
• The initial launch price offered was US $ 6 million, without options or a HAPS ( Hydrazine Auxiliary Propulsion System ) maneuvering stage.
• LPSC is engaged in development of liquid and cryogenic propulsion stages for launch vehicles and auxiliary propulsion systems for both launch vehicles and satellites.
• Since the third ( S-IVB ) stage has only one engine, an auxiliary propulsion system was used for roll control during powered flight.
• A Hydrazine Auxiliary Propulsion System upper stage was flown aboard the Minotaur to demonstrate its ability to deploy payloads to multiple orbits, however only mass simulators were deployed after the HAPS burn.
• Two liquid-fueled Auxiliary Propulsion System ( APS ) units mounted at the aft end of the stage were used for attitude control during the parking orbit and the trans-lunar phases of the mission.
• If it were to remain on the same trajectory as the spacecraft, the S-IVB could have presented a collision hazard so its remaining propellants were vented and the auxiliary propulsion system fired to move it away.
• On the 500 series this was reduced to two, and two small APS ( auxiliary propulsion system ) thruster modules were added as ullage motors for restarting the J-2 engine and to provide attitude control during coast phases of flight.
• Persei ( Perseus ) and "'14S49 "', which incorporated most features of the proposed "'11C861-03 Phase II "', including the use of nontoxic propellants in auxiliary propulsion systems and new compact flight control system.
• Many modern trolleybuses are equipped with auxiliary propulsion systems, either using a small diesel engine or battery power, allowing movement away from the overhead wires, called " off-wire " movement, but such vehicles are generally not considered to be dual-mode buses if their off-wire capability is very limited.
