Abstract:
This flight vehicle comprises a rotor shaft projecting upward from a body, a rotor head connected to the rotor shaft above the body, and a pair of plate units that are disposed above the body and extend in the longitudinal direction on the right and left sides of the rotor shaft. The pair of plate units each include a front end, a rear end, an inner-side surface facing inward in the left-right direction, and an outer-side surface facing outward in the left-right direction. The front ends of the pair of plate units are separated from each other in the left-right direction. The rear ends of the pair of plate units are separated from each other in the left-right direction. The pair of plate units are shaped such that the pressure on the outer-side surfaces is lower than the pressure on the inner-side surfaces during forward flight.
