1. A manned aircraft comprising:
a flight part provided with a blade part and a thrust generating part provided on the blade part;
an airframe part supporting the flight part; and
a boarding part that is displaceable independently from the airframe part, wherein the blade part includes a front blade part and a rear blade part, which are respectively connected to a front end and a rear end of the airframe part in a first horizontal direction, the front and the rear blade parts each having a wing shape that extends in a second horizontal direction, the second horizontal direction being substantially perpendicular to the first horizontal direction,
wherein the thrust generating part includes a first plurality of propellers and a second plurality of propellers, the first plurality of propellers being provided on the front blade part, the second plurality of propellers being provided on the rear blade part, each propeller being an unducted propeller,
wherein a center of gravity of the boarding part substantially coincides with a center of the airframe part,
wherein the front blade part and the rear blade part are mounted on the airframe part in symmetrical positions around the boarding part, and a first part of the airframe part that connects to the front blade part, the center of gravity of the boarding part, and a second part of the airframe part that connects to the rear blade part are arranged to be in a straight line,
wherein a fixed angle formed between the airframe part and the front blade part on a leading edge side of the boarding part is an obtuse angle, and a fixed angle formed between the airframe part and the rear blade part on a trailing edge side of the boarding part opposite the leading edge side is an acute angle,
wherein the airframe part includes a substantially annular receiving part, the boarding part being disposed inside the annular receiving part, and
the boarding part has a substantially annular shape corresponding to a shape of the annular receiving part, and is configured to be independently displaceable in a substantially annular circumferential direction.
