ullage

Excessive ullage in a tank may contribute to the free surface effect.

They also aided stage separation, and acted as ullage motors.

The ullage level can also give insight as to the type of care and storage condition that the wine was kept in.

December 11, 1964: Restart attempt failed, due to problem with ullage rockets.

After all, the ullage is what Flight 800 investigators think filled with dangerous fumes and then exploded.

The ullage level of a wine bottle is sometime described as the "fill level".

This reduces the oxygen concentration of the ullage to below the combustion threshold.

Modern tanks are not fitted with ullage valves.

My flogging by pimply old Ullage was no unmerciful affair in itself.

A key clue to the condition of wine is ullage: the fill level in the bottle resulting from evaporation.

This practice may have consciously increased since the removal of a duty allowance on ullage (wastage).

High-shoulder ullage should present no problems.

The roll thrusters are cross-fed by gas drawn from ullage space of the opposite tank.

The Tucci master list notes a degree of ullage in some of the bottles.

Generally the greater the amount of ullage, the more potential that the wine has been exposed to harmful levels of oxidation.

In liquid rockets, ullage is the space within a fuel tank above the liquid propellant.

This is accomplished by ventilating fuel vapor laden ullage gas out of the tank and into the atmosphere.

Mr. Spiller has filled the show with intriguing questions that the exhibits answer, like "What is ullage?"

Ullage is a loss of wine either through evaporation or leakage, and it is not uncommon in old wines.

Meanwhile, the succeeding stage may have ullage rockets, both to aid separation and ensure good starting of liquid-fuel engines.

During the bottling process, most wineries strive to have an initial ullage level of between 0.2-0.4 inches (5-10mm).

This is because the pressure of the air bubble that is the ullage space rises and falls depending on temperature fluctuation.

Under this same traditional style of winemaking, a large ullage or air space would emerge in the barrel and oxidation took place.

Two other methods in current use to inert fuel tanks are a foam suppressant system and a ullage system.

The footage also shows the more conspicuous plumes of the solid ullage motors as they pull the stages apart before the main engines are fired.
