Abstract

An aircraft includes a fuselage, a wing disposed above the fuselage, a pylon connecting the wing to the fuselage, and a plurality of internal combustion engines housed in the fuselage. The pylon vertically traverses the fuselage and is fixed to an upper portion and a lower portion of the fuselage. Among the plurality of internal combustion engines, a first internal combustion engine and a second internal combustion engine are disposed bilaterally symmetrically about the pylon and are fixed to the pylon.

First claim

What is claimed is:

1. An aircraft comprising:
a fuselage;
a wing disposed above the fuselage;
a pylon configured to connect the wing to the fuselage; and
a plurality of internal combustion engines housed in the fuselage, wherein
the pylon vertically traverses the fuselage and is directly fixed to an upper portion and directly fixed to a lower portion of the fuselage, and
among the plurality of internal combustion engines, a first internal combustion engine and a second internal combustion engine are disposed bilaterally symmetrically about the pylon, and are fixed to the pylon.

2. The aircraft according to claim 1 , wherein
among the plurality of internal combustion engines, a third internal combustion engine is disposed at a position offset rearward and downward from a position between the first internal combustion engine and the second internal combustion engine.

3. The aircraft according to claim 1 , wherein
the pylon has a shape in which a length of the pylon in a front-rear direction decreases from an upper end portion of the pylon toward a lower end portion thereof, and the pylon is disposed so as to be inclined rearward with respect to a plane passing through the lower end portion of the pylon and extending in a vertical direction and a left-right direction.

4. The aircraft according to claim 1 , wherein
the fuselage includes a first fuselage portion, and a second fuselage portion contiguously connected to a rear end portion of the first fuselage portion,
the first fuselage portion includes a plurality of outer panels, a plurality of stringers, and a plurality of frames,
the pylon is fixed to an upper portion and a lower portion of a rear surface of one of the frames, and
the first internal combustion engine and the second internal combustion engine are housed in the second fuselage portion.

5. The aircraft according to claim 4 , wherein
the first internal combustion engine and the second internal combustion engine are fixed to the frame.

6. The aircraft according to claim 1 , wherein
an output shaft of each of the internal combustion engines is connected to a main shaft of a generator.
