Abstract
A method is disclosed of transferring energy into a flow of air without use of rotating parts, in which an inlet flow of air is made to swirl into a first circular path moving longitudinally of a housing, heat is added to the inlet flow of air at the end of the first path to produce hot gases, and the hot gases are directed into a second swirling circular path coaxially of and within the first path and having an open interface therewith, whereby energy is transferred from the hot gases in the second path into the inlet flow of air in the first path. An embodiment of the method is disclosed in the form of a fluid mass reaction engine having an annular housing including an inlet thereinto and an outlet therefrom, a combustion chamber in the housing spaced from the inlet, spaced coaxial openings into and out of the combustion chamber, and a means for heating air flowing through said combustion chamber. A first swirling device acts on air entering the inlet to produce a circular flow of air moving into the combustion chamber and having a substantial component of centrifugal velocity, a second swirling means acts on hot gases flowing out of the combustion chamber to produce a swirling f…
