Mechanical structures adapted to produce thrust. Said structures include components and mass that rotate about two axes of rotation (20, 10) perpendicular to each other and in two-to-one relationship. In operation, the radius of the rotating mass lengthens and shortens so as to cause unequal forces and unequal pressures to develop at predetermined sections in the cycle of rotation. One structure includes two chambers (21) each having a length and a width and each adapted to permit an inflow (45) and outflow (46) of fluid. The other structure includes a shuttle having two sets of mass members (31), one set of mass members in each chamber. During operation the length of the front chamber aligns vertically, while the length of the back chamber aligns horizontally and the set of mass members within each chamber aligns angularly to said length. The unequal pressures and centrifugal forces (42, 43) cause inflow of fluid into the front chamber and outflow of fluid fron the back chamber and the unequal centrifugal forces pull the front mass members apart and the back mass members together which propel the shuttle in a linear movement backward (41). In reaction to the flow of fluid and to said linear movement the frame moves forward (44').
