ullage การใช้

• They also aided stage separation, and acted as ullage motors.
• Excessive ullage in a tank may contribute to the free surface effect.
• This reduces the oxygen concentration of the ullage to below the combustion threshold.
• Attitude control and ullage are provided by means of hydrazine monopropellant thrusters located around the stage.
• Ullage levels are generally important to the likelihood of almost any wine being in good shape.
• In addition, the heat from the ullage rockets could potentially ignite the propellants in the stage.
• Engines devoted to this purpose are called ullage motors; sometimes reaction control system thrusters are used.
• After all, the ullage is what Flight 800 investigators think filled with dangerous fumes and then exploded.
• This is accomplished by ventilating fuel vapor laden ullage gas out of the tank and into the atmosphere.
• This practice may have consciously increased since the removal of a duty allowance on ullage ( wastage ).
• This causes the ullage fuel-to-air ratio to increase rapidly and exceed the lower flammability limit.
• In the S-IVB third stage, there was an Auxiliary Propulsion System that also had ullage functions.
• Ullage, the injection pressure, affected the reliability of the gun, but not its safety or operation.
• In May 2016, the band released their second album, " Ullages, " on Partisan Records.
• Ullage is often a secondary function of the reaction control system such as on the Apollo Lunar Module ( LM ).
• There are standard descriptions used by wine merchants and auction houses for the fill levels ( ullage levels ) of wine.
• Generally the greater the amount of ullage, the more potential that the wine has been exposed to harmful levels of oxidation.
• The ullage level can also give insight as to the type of care and storage condition that the wine was kept in.
• This ullage or headspace area contains more oxygen and thus speeds atmospheric corrosion, as evidenced by the appearance of rust scales.
• Meanwhile, the succeeding stage may have ullage rockets, both to aid separation and ensure good starting of liquid-fuel engines.
