Abstract: The Toroid Sweep Engine with Reciprocating Jut generates power within a toroidal-shaped chamber whose walls are divided into two ring-like sections which are free to rotate relative to one another around the toroid axis. An obstacle juts from each of the wall sections into the chamber. Fresh air is pumped at high pressure and high temperature into a region of the chamber between the two obstacles, and fuel is then injected into and burned in this region. The products of combustion force the obstacles apart, turning a wall section, and when the obstacles eventually meet after circumnavigation of the toroid, one of them withdraws from the chamber allowing the obstacles to pass. More fresh air and fuel are introduced between the again separating obstacles following the rendezvous, while spent gases from the previous burning are swept and squeezed out an exhaust duct leading from that volume within the chamber which is compressed between the obstacles.
