Aircraft with reciprocating engines partially embedded in the fuselage
View Patent ↗An aircraft provided with turbojet engines of which the nacelles are partially embedded in the fuselage of the aircraft is disclosed. The aircraft includes an internal space at engine nacelles. The internal space includes a platform capable of supporting personnel and maintenance equipment, with the portions of the nacelles located inside the aircraft comprising trapdoors or devices for accessing inside the engines from the platform.
1. An aircraft provided with at least two turbojet engines comprising:
nacelles partially embedded in a fuselage of the aircraft,
wherein the aircraft comprises an internal space delimited by an enlarged rear portion of the fuselage of each side of the aircraft, the enlarged rear portion being aft of a wing of the aircraft and wider than an upstream portion of the fuselage and forming the engine nacelles and the engines are disposed in the internal space, the internal space comprising a platform capable of supporting personnel and maintenance equipment, with portions of the nacelles located inside the aircraft comprising trapdoors or means for accessing inside both of the engines from the platform, and
wherein the enlarged rear portion of the fuselage forming the engine nacelles further comprises at an upstream end air inlet openings facing upstream for feeding the turbojets with air from outside of the aircraft.
2. The aircraft according to claim 1 , wherein the platform is carried by a floor of the aircraft.
3. The aircraft according to claim 2 , wherein the platform extends from one engine to another engine inside the aircraft.
4. The aircraft according to claim 1 , wherein certain portions of the engines located inside the aircraft are devoid of protective covers.
5. The aircraft according to claim 1 , wherein each engine comprises at least one casing surrounding the engine, the casing having a portion located inside the aircraft carrying equipment that can be replaced during a stop-over.
6. The aircraft according to claim 5 , wherein the equipment that can be replaced during a stop-over includes at least one element among a calculator, an electrical lead, an ignition exciter box, a lubricating module, a speed sensor, an oil tank, and a starter.
7. The aircraft according to claim 1 , wherein the platform is disposed below axes of the engines.
8. The aircraft according to claim 1 , wherein the engines are not connected to the fuselage by pylons.
9. The aircraft according to claim 1 , wherein the enlarged rear portion of the fuselage forming the engine nacelles further comprises outlet openings downstream of the engines for ejecting air from the engines to the outside of the aircraft.
