CYCLIC TYPE THRUST CHANGE TYPE CLIMATE ADAPTATION CRAFT

摘要

PROBLEM TO BE SOLVED: To provide a climate adaptation craft which reduces generation of sound noise and discharge of dust, CO2 and NOX and the like from a propulsive power and to provide a flight pattern for the craft.;SOLUTION: A cyclic type thrust system is introduced and as the flight pattern, flight in a phugoid mode is performed. In a propeller plane, a cyclic type power device drives a fly wheel type propeller. In a jet plane, fuel is supplied in a cyclic manner to a propulsive power device. In an electric plane, a storage battery supplies power to a motor for driving a fly wheel type propeller in a cyclic manner. Cycle period of these planes is determined so as to continue phugoid mode motion. A plane shape is formed into a shape which facilitates phugoid mode, namely, a wing profile with large lift inclination, and a wing flat shape or a main wing oval shape with large lift inclination, lift-drag ratio, and aspect ratio. These kinds of climate adaptation technique can be applied to planes of a single engine plane and a two-motored plane, and a plane having more engines.;COPYRIGHT: (C)2014,JPO&INPIT
