Abstract:
A rotary apparatus comprising:a hinged rotor assembly having rotor segments, with each said rotor segment having opposite tips, said opposite tips defining: points A and B, and a point P midway therebetween, and a right isosceles triangle including points A and B and having a vertex point C inside of said hinged rotor; and a coaxial rotor housing in which said hinged rotor is housed for rotation, said rotor housing including two flat-plate side covers and an internal profile, the internal profile being: generally oval so as to define an X major axis and a Y minor axis which intersect at an origin point O, defined by having point P of each rotor segment moving along a circle with a center at origin point O and with a radius equal to one half of a distance between points A and B, and defined by having vertex point C always located on one of four lobes of the curve r=sin[2(&thgr;+45Â°)]â€ƒwhere: angle &thgr; is the angle between the line connecting points O and A and a positive portion of axis Y, and angle &thgr; is also the angle between the line connecting points O and B and a positive portion of axis X, and r equals the length of the line connecting points O and C.
