A tailless aircraft is known as an airplane with the merit of little air drag since the tail and the fuselage, which connects the main wing with the tail plane, do not exist. It also has the demerit of instability in maneuvering in the longitudinal direction. Our team at Ritsumeikan University has been daring to participate in the birdman-rally with the tailless aircraft, but a good result has not yet been obtained. The purpose of this paper is to study and to develop the tailless aircraft for the birdman-rally by computational fluid dynamics. The data of the flight at the last rally were analyzed, and the problems and solutions were obtained.
