Abstract
Device intended for a double glazing including at least one outer glazing and one inner glazing separated by an intermediary space filled with a gas, used to isolate an inside environment from an outside environment, a pressure variation being liable to occur between these environments, for example in the case of an aircraft in flight, includes means for conserving the outer glazing and the inner glazing of this double glazing mainly parallel, independently of this pressure variation. The invention also concerns a double glazing including this device, the process for maintaining parallelism and software using the process.
Claims13
A device comprising:
- a double wall including at least one outer wall and one inner wall separated by an intermediary space filled with a gas, the double wall separating an inside environment from an outside environment, and a pressure variation liable to occur between the inside and the outside environments;
- and
- means to maintain the outer wall and the inner wall of the double wall substantially parallel independently of the pressure variation,
- wherein the means to maintain the outer wall and the inner wall of the double wall substantially parallel comprises:
- measuring means for measurement of at least one parameter comprising a distance directly related to a differential deformation between the inner and outer walls,
- pressurization means configured for increasing or reducing the pressure in the intermediary space, and
- control means for controlling the pressurization means according to the at least one parameter measured and according to a previously stored logic.
A double glazing including at least an outer glazing and an inner glazing separated by an intermediary space filled with a gas, the double glazing separating an inside environment from an outside environment, a pressure variation of predetermined maximum amplitude being liable to occur between the inside and outside environments, and comprising a device, the device comprising means to maintain the outer glazing and the inner glazing of the double glazing substantially parallel independently of the pressure variation,
- wherein the means to maintain the outer glazing and the inner glazing of the double glazing substantially parallel comprises:
- measuring means for measurement of at least one parameter comprising a distance directly related to a differential deformation between the inner and outer glazings,
- pressurization means configured for increasing or reducing the pressure in the intermediary space, and
- control means for controlling the pressurization means according to the at least one parameter measured and according to a previously stored logic.
