Title:
MANUAL VERTICAL TAKE-OFF AND LANDING AIRCRAFT WITH AUTOMATIC CENTRIFUGAL VARIABLE PITCH ROTOR
Document Type and Number:
Japanese Patent JP2008094368
Kind Code:
A
Abstract:
To restrict consumption of the kinetic energy before take-off by reducing the weight to the utmost limit.
Respective driving shaft of two rotary blades are inclined at 13.6 degree, and respective rotors are rotated in the opposite directions to avoid a contact with each other, and a span is thereby shortened, and the weight can be reduced. As the rotor, a variable pitch type is used. Moreover, a light automatic centrifugal rotor of simple structure is used.
