Abstract

792,831. Gas turbine jet propulsion plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 1, 1956 [March 11, 1955], No. 7193/55. Class 110 (3). [Also in Group XXIX] The air flow in the air intake duct or jet pipe of a jet propulsion plant is controlled by means comprising a first set of spaced-apart vanes extending across the duct or jet pipe and a second set of spaced-apart vanes movable into or out of an operative position in which the vanes of the two sets interdigitate to divide the path of the gas flowing between adjacent vanes and so constrict the passage. An air intake duct 1 or jet pipe of a gas turbine jet propulsion plant has at one end an orifice 3. The means for restricting the flow comprises a first set of spaced-apart vanes 4 which extend radially across the duct and are secured at their inner ends to an annulus 5 and at their outer ends to the duct wall 1, and a second set of spaced-apart vanes 6 which are supported on a cylindrical body 7 slidable along the axis of the duct. The body 7 is actuated by pinions 10 and a rack housed in a conical fairing 9. The vanes 6 may be moved between the inoperative position, Fig. 3, to the operative position, Fig. 4, to vary the degree of constriction of the flow. Means for supplying a heating or cooling fluid to the leading or trailing edges of the vanes is described. In a modification, the vanes 6 are made movable in a direction normal to the flow of fluid. The duct may be made of rectangular, elliptical or of other cross-section, in which case the vanes of the first and second sets will extend across the duct parallel to one another.
