Abstract
An equipment unit for installation in an aircraft includes an enclosure, in which at least one movable mechanical element is arranged, a supply duct, and a non-return valve, wherein the enclosure includes an inflow port and an outflow port, wherein the supply duct is connected to the inflow port, wherein the non-return valve is connected to the outflow port, wherein the supply duct is connectable to a source of heated air providable in the respective aircraft, and wherein the enclosure is designed that air supplied through the supply duct enters the enclosure through the inflow port, picks up moisture from inside the enclosure and exits through the outflow port.
Claims10
An equipment unit for installation in an aircraft, comprising:
- an enclosure, in which at least one movable mechanical element is disposed, the enclosure comprising an inflow port and an outflow port;
- a supply duct connected to the inflow port;
- a non-return valve connected to the outflow port;
- the supply duct being connectable to a source of heated air providable in the aircraft;
- and
- the enclosure configured so air supplied continuously through the supply duct can enter the enclosure through the inflow port, pick up moisture from inside the enclosure, and exit through the outflow port once an overpressure sufficient to operate the non-return valve is produced.
A method for drying an enclosure of an equipment unit in an aircraft comprising at least one movable mechanical element, the method comprising:
- continuously flowing heated air from a source provided in the aircraft to an inflow port of the enclosure;
- removing moisture from inside the enclosure with the heated air;
- and
- once an overpressure sufficient to operate a non-return valve is produced, flowing the heated air through an outflow port of the enclosure.
