PASSENGER AIRCRAFT
The invention has as its purpose an aircraft for transport of passengers having a fuselage ( 1 ) comprising a pressurized level ( 2 ) in which there are laid out the passenger cabin ( 20 ) and a lower level forming a hold ( 3 ). According to the invention, the cockpit ( 40 ) is positioned in an additional pressurized space ( 4 ) laid out below the main deck ( 10 ), at the level of the hold ( 3 ) and separated from the latter by a structure ( 41 ) withstanding possible impacts.
1 . Aircraft for transport of passengers comprising a cockpit ( 40 ) and a cabin ( 20 ) for passengers inside a fuselage ( 1 ) divided into two levels by a floor ( 10 ) forming a main deck, respectively an upper pressurized level ( 2 ) and a lower level forming a hold ( 3 ) for the loads transported,
characterized by the fact that the cockpit ( 40 ) is positioned in a pressurized space ( 4 ) laid out in front of the hold ( 3 ) and at the same level as the latter, below the floor ( 10 ) of the passenger cabin that extends over the entire length of the fuselage ( 1 ), the said front pressurized space ( 4 ) being closed toward the rear by a structure ( 41 ) withstanding the possible impacts coming from the hold ( 3 ).
2 . Aircraft according to claim 1 , characterized by the fact that, the hold ( 3 ) being laid out on a lower floor ( 11 ), the front portion of the latter forms the floor ( 45 ) of the cockpit ( 40 ).
3 . Aircraft according to claim 2 , characterized by the fact that the front end of the lower floor ( 11 ) is slightly raised so as to impart a sufficient width to the cockpit, taking into account the pointed shape of the fuselage ( 1 ).
4 . Aircraft according to one of the preceding claims, characterized by the fact that the upper floor ( 10 ) on which the passenger cabin ( 20 ) is laid out is slightly elevated at its front end, so as to impart a sufficient height to the cockpit ( 40 ).
5 . Aircraft according to claim 4 , characterized by the fact that the upper floor ( 10 ) bearing the passenger cabin ( 20 ) terminates, at the front tip, with an upward-sloping portion.
6 . Aircraft according to claim 5 , characterized by the fact that the sloping portion, at the front tip of the upper floor ( 10 ), is provided with a hatchway forming an emergency exit ( 47 ).
7 . Aircraft according to claim 3 , characterized by the fact that the elevated front portion ( 42 ) of the floor ( 45 ) of the cockpit ( 40 ) defines a storage compartment ( 50 ) for the front landing gear ( 5 ), in withdrawn position.
8 . Aircraft according to one of the preceding claims, characterized by the fact that the front pressurized space ( 4 ) of the lower level ( 3 ) comprises, between the resistant structure ( 41 ) separating the hold ( 3 ) and the cockpit ( 40 ), at least one area ( 7 ) forming a personal space for the crew.
9 . Aircraft according to claim 8 , characterized by the fact that the front pressurized space ( 4 ) of the lower level ( 3 ) comprises, between the personal space ( 7 ) for the crew and the separating resistant structure ( 41 ), a technical area ( 70 ) for electronic cabinets and various pieces of control equipment.
10 . Aircraft according to one of the preceding claims, characterized by the fact that the front pressurized space ( 4 ) of the lower level ( 3 ) communicates with the outside through at least one main access door ( 45 ) positioned at the level of the lower floor ( 11 ) and opening either directly into the cockpit ( 40 ) or into a personal space ( 7 ) laid out behind the latter.
11 . Aircraft according to claim 10 , characterized by the fact that the area forming the personal space ( 7 ) comprises a central aisle ( 71 ) for access to the technical area ( 70 ), running between two modules ( 72 ) forming rest areas for the crew, at the level of which the fuselage is provided with windows ( 63 ).
12 . Aircraft according to one of the preceding claims, characterized by the fact that the passenger cabin ( 20 ) comprises, at the front of the fuselage ( 1 ), a pointed portion extending above the cockpit ( 40 ) and at the level of which the fuselage ( 1 ) is provided with a row of windows ( 61 ) forming a panoramic window wall.
13 . Aircraft according to claim 12 , characterized by the fact that the pointed portion of the passenger cabin ( 20 ) is equipped, at its front end, with two armchairs ( 22 ) in front of which there is positioned a piece of equipment suggesting the configuration of a cockpit, provided with screens for the display of aircraft flight information.
14 . Aircraft according to preceding claims, characterized by the fact that the cockpit ( 20 ) is equipped, on each side, with video cameras trained toward the rear in order to increase the field of vision of the pilots.
