Abstract

A double-deck airplane that facilitates passenger embarking/disembarking and cargo loading/unloading operations in order to maximize the number of flight missions carried out in a given time. The floors of its upper and lower decks are planar surfaces extending continuously inside the fuselage in at least the inner space of the fuselage intended for the payload; the lower deck is located at a height from the ground that allows carrying out passenger embarking/disembarking via equipment incorporated in the airplane without any external airport ground equipment; passenger and/or cargo compartments are distributed on the upper and/or lower decks; and the lifting structure is disposed in the airplane in a manner that none of its components crosses the upper and lower decks.

First claim

The invention claimed is:

1. A double-deck airplane for transporting passengers and/or cargo comprising a fuselage, a upper deck, a lower deck, a movable partition wall on the upper deck or the lower deck, a lifting structure, landing gears and a propulsion system, wherein:
floors of the upper and lower decks are planar surfaces extending continuously inside the fuselage in at least an inner space of the fuselage configured for a payload, wherein the upper and lower decks each extends in a plane continuously from a front section of the fuselage to an empennage section of the airplane;
the lower deck is located at a height from the ground, while the aircraft is on the ground, configured to carry out passenger embarking/disembarking via equipment incorporated in the airplane without any external airport ground equipment;
passenger or cargo compartments are distributed on the upper and lower decks;
the lifting structure is disposed in the airplane in a manner that no component of the lifting structure crosses the upper and lower decks;
the movable partition wall is configured to separate the passenger compartment from the cargo compartment, the movable partition wall extends from the floor of the lower or upper deck to a ceiling of the lower or upper deck and extends transversely from a left wall to a right wall of the fuselage, and the movable partition wall is movable along a longitudinal direction of the fuselage; and
a distribution of the inner space allocated to the passengers and/or cargo compartments is changeable by locating the partition wall at different positions along the longitudinal direction of the fuselage.

2. The double-deck airplane according to claim 1 , wherein the seats of the passenger compartments are foldable seats that are installed on guides such that they can be folded/unfolded and moved along the longitudinal direction of the fuselage for their accommodation to a position of the movable partition wall.

3. The double-deck airplane according to claim 1 , wherein the fuselage has at least lower doors accessible from ground via equipment incorporated in the airplane and upper doors accessible from jetways or boarding stairs.

4. The double-deck airplane accordingly to claim 1 , wherein
the fuselage has at least one lower door to at least one of the passenger compartments, the lower access door including built-in stairs so that the lower access door can be used for embarking/disembarking passengers directly from/to the ground.

5. The double deck airplane according to claim 1 , wherein:
the lifting structure comprises a low wing and a T-shaped section at the empennage; and
the propulsion system comprises engines mounted to a rear part of the airplane.

6. The double-deck airplane according to claim 5 , wherein the landing gears comprise a nose landing gear and a main landing gear that are housed in fairings attached to the fuselage.

7. The double-deck airplane according to claim 5 , wherein the landing gears comprise a nose landing gear and a main landing gear housed under the low wing.

8. The double-deck airplane according to claim 1 , wherein:
the lifting structure comprises a low wing and the empennage formed by a vertical tail plane and a horizontal tail plane located at an intermediate position of the vertical tail plane;
the propulsion system comprises engines mounted to the upper side of the low wing at each side of the fuselage in a forward location with respect to the low wing; and
the landing gears comprise a nose landing gear and a main landing gear housed in the low wing.

9. The double-deck airplane according to claim 1 , wherein:
the lifting structure comprises a low wing and a T-shaped section at the empennage;
the propulsion system comprises engines mounted to the upper side of the low wing at each side of the fuselage in a rearward location with respect to the low wing; and
the landing gears comprise a nose landing gear and a main landing gear housed in fairings attached to the fuselage.

10. The double-deck airplane according to claim 1 , wherein:
the lifting structure comprises a high wing and a T-shaped section of the empennage;
the propulsion system comprises engines mounted under the high wing at each side of the fuselage; and
the landing gears comprise a nose landing gear and a main landing gear housed in fairings attached to the fuselage.

11. The double-deck airplane according to claim 10 , wherein a front portion of the fuselage includes an access door to the lower deck and the access door is aligned with the longitudinal direction of the fuselage when opened.

12. The double-deck airplane according to claim 10 , wherein a rear portion of the fuselage is configured as a two-part access door to the lower deck arranged such that each part of the two-part access door is opened in a direction transverse to the longitudinal direction of the fuselage.

13. The double-deck airplane according to claim 1 , wherein the cockpit is located on the upper deck in a frontal portion of the fuselage.

14. A double-deck airplane comprising:
a fuselage including an upper deck and a lower deck;
floors of the upper and lower decks that extend continuously in at least a payload space of the fuselage, the upper and lower decks extending continuously from a front region of the fuselage to an empennage region of the airplane,
wherein the payload space of the fuselage is dividable into a passenger compartment and a cargo compartment;
an adjustable divider separates the passenger compartment from the cargo compartment, the adjustable divider extends from the floor of the lower or upper deck to a ceiling of the lower or upper deck and extends transversely from a left wall to a right wall of the fuselage, and the adjustable divider is movable along a longitudinal direction of the fuselage,
wherein a distribution of the payload space allocated to the passenger and cargo compartments is changeable by locating the divider at different positions along the longitudinal direction of the fuselage;
a wing structure extending outwards from opposite sides of the fuselage, wherein the wing structure is configured to avoid the payload space; and
embarking/disembarking equipment in the fuselage and configured to be deployed while the aircraft is on the ground, wherein the lower deck is located at a height from the ground, while the aircraft is on the ground, that allows embarking/disembarking passengers from the lower deck via the embarking/disembarking equipment without external ground equipment.

15. The double-deck airplane according to claim 14 , wherein the adjuster divider is a movable partition wall.

16. The double-deck airplane according to claim 14 , wherein the embarking/disembarking equipment incorporated in the airplane includes rollable stairs in a door of the fuselage adjacent the lower deck.
