Pressurized sliding door
Embodiments are directed to systems and methods for a sliding door in a pressurized aircraft. In one embodiment, an aircraft comprises a fuselage having a door opening, and a door configured to slide into the door opening from within the fuselage, the door held in a closed position in the door opening by excess air pressure within the fuselage during operation of the aircraft.
1. An aircraft, comprising:
a fuselage having a door opening;
a door configured to slide into the door opening from within the fuselage, wherein the door is configured to slide horizontally within the fuselage between an open position and the closed position, wherein an inner edge of the door opening is wider than an outer edge of the door opening and wherein the edges are adapted to prevent the door from moving outside the door opening, and wherein the door is held in a closed position in the door opening by excess air pressure within the fuselage during operation of the aircraft.
2. The aircraft of claim 1 , further comprising:
an environmental control system configured to generate an air pressure within the fuselage that is greater than an air pressure outside the fuselage.
3. The aircraft of claim 1 , wherein the excess air pressure within the fuselage is generated using engine bleed air or mechanically or electrically driven air compressors.
4. The aircraft of claim 1 , further comprising:
tracks located in an aircraft cabin floor; and
guides attached to the door and coupled to the tracks, wherein the tracks are configured to control the location of the door between an open position and the closed position.
5. The aircraft of claim 4 , further comprising:
tracks located in an aircraft cabin ceiling.
6. The aircraft of claim 1 , further comprising:
a gasket mounted on the door opening, the gasket adapted to form a seal between the door opening and the door in a closed position.
7. The aircraft of claim 6 , wherein the gasket is inflatable using engine bleed air or mechanically or electrically driven air compressors.
8. The aircraft of claim 1 , further comprising:
a gasket mounted on the door, the gasket adapted to form a seal between the door opening and the door in a closed position.
9. The aircraft of claim 1 , wherein the edge has a ramped or sloped shape.
10. The aircraft of claim 1 , wherein the edge has a rectangular stepped shape, and wherein a lip or ridge on the edge of the door opening prevents the door from moving past the door opening due to excess air pressure within the fuselage.
11. An aircraft door system, comprising:
tracks disposed on or in an aircraft cabin floor;
a door configured to slide into a door opening from within a fuselage, wherein the door is configured to slide horizontally within the fuselage between an open position and the closed position; and
guides attached to the door and coupled to the tracks, wherein the tracks are configured to control the location of the door between an open position and the closed position,
wherein an inner edge of the door opening is wider than an outer edge of the door opening and wherein the edges are adapted to prevent the door from moving outside the door opening, and wherein the door is held in a closed position in the door opening by excess air pressure within the fuselage during operation of the aircraft.
12. The aircraft door system of claim 11 , further comprising:
tracks located in an aircraft cabin ceiling.
13. The aircraft door system of claim 11 , further comprising:
a gasket mounted on the door opening, the gasket adapted to form a seal between the door opening and the door in a closed position.
14. The aircraft door system of claim 13 , wherein the gasket is inflatable using engine bleed air or mechanically or electrically driven air compressors.
15. The aircraft door system of claim 11 , further comprising:
a gasket mounted on the door, the gasket adapted to form a seal between the door opening and the door in a closed position.
16. The aircraft door system of claim 11 , wherein the edge has a ramped or sloped shape, or wherein a lip or ridge on the edge of the door opening prevents the door from moving past the door opening due to excess air pressure within the fuselage.
17. The aircraft door system of claim 11 , wherein the edge has a rectangular stepped shape, and wherein a lip or ridge on the edge of the door opening prevents the door from moving past the door opening due to excess air pressure within the fuselage.
