Autor: Masahiko Sugiura, Yasutada Tanabe, Naoki Matayoshi, Hideaki Sugawara, Hirokazu Ishii
Publikováno v: Journal of Aircraft. 54:209-219
When a helicopter takes off, lands, or makes hovering or taxiing flights in ground effect, its downwash interferes with the ground. Encounters with such highly turbulent helicopter wakes have resulted in the two small fixed-wing aircraft crashes in t

A New Concept of Compound Helicopter and Flight Tests
Autor: Yasutada Tanabe, Noboru Kobiki, Masahiko Sugiura, Hideaki Sugawara
Publikováno v: Lecture Notes in Electrical Engineering ISBN: 9789811333040
A new concept of compound helicopter to achieve high speed of two times of a conventional helicopter is described. This configuration consists of a single main rotor and a main fixed wing. Antitorque is performed through two electric driven propeller

A Study on Aerodynamic Drag Reduction for High Speed Helicopter Airframe
Autor: Noboru Kobiki, Masahiko Sugiura, Yasutada Tanabe, Hideaki Sugawara
Publikováno v: Lecture Notes in Electrical Engineering ISBN: 9789811333040
JAXA is proposing a concept of a high speed EMS compound helicopter with the maximum cruise speed 500 km/h which is twice as fast as conventional helicopters. In order to realize this high speed within an envelope of the existing propulsion system, i

A Study of Desired Configuration and Dynamics of an Unmanned Aerial Vehicle for Photography
Autor: Masahiko Sugiura, Keiji Kawachi
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C. 73:296-304
Two problems were numerically analyzed for an unmanned aerial vehicle for aerial photography. Height control in backside of drag curve was studied, using optimal regulator and optimal control theories. It was shown that the optimal solution without l
