    摘要: An axial flow positive displacement engine (8) has an inlet (20) axially spaced apart and upstream from an outlet (22). Inner and outer bodies (12, 14) have offset inner and outer axes (16, 18) extend from the inlet (20) to the outlet (22) through first, second, and third sections (24, 26, 28) in serial downstream flow relationship. At least one of the bodies is rotatable about its axis. The inner and outer bodies (12, 14) have intermeshed inner and outer helical blades (17, 27) wound about the inner and outer axes (16, 18) respectively. The inner and outer helical blades (17, 27) extend radially outwardly and inwardly respectively. The helical blades have first, second, and third twist slopes (34, 36, 38) in the first, second, and third sections (24, 26, 28) respectively. The first twist slopes (34) are less than the second twist slopes (36) and the third twist slopes (38) are greater than the second twist slopes (36). A combustion section (40) extends axially downstream from the second section (26) through at least a portion (42) of the third section (28).

    摘要: An axial flow positive displacement engine (8) has an inlet (20) axially spaced apart and upstream from an outlet (22). Inner and outer bodies (12, 14) have offset inner and outer axes (16, 18) extend from the inlet (20) to the outlet (22) through first, second, and third sections (24, 26, 28) of a core assembly (15) in serial downstream flow relationship. At least one of the bodies is rotatable about its axis. The inner and outer bodies (12, 14) have intermeshed inner and outer helical blades (17, 27) wound about the inner and outer axes (16, 18) respectively. The inner and outer helical blades (17, 27) extend radially outwardly and inwardly respectively. The helical blades have first, second; and third twist slopes (34, 36, 38) in the first, second, and third sections (24, 26, 28) respectively. The first twist slopes (34) are less than the second twist slopes (36) and the third twist slopes (38) are less than the second twist slopes (36). A combustor section (40) extends axially downstream through at least a portion of the second section (26).
