ABSTRACT:
Gas turbine engine power plants of the ducted fan type. During reversed thrust operation of the power plant, air is induced into the bypass duct through two inlets in one type of power plant is concerned. One of these, a secondary inlet, is located between a stationary front section of the bypass duct and a translated rear section. A gas or fluid such as air is injected at high velocity into the bypass duct to turn air induced through the secondary inlet into paths paralleling the longitudinal centerline of the duct or to accomplish this goal and also promote the attachment of induced air to the inner surface of the bypass duct. In both cases, the efficiency of the power plant in the reversed thrust mode of operation is increased. A second type of power plant of interest does not have a translatable rear section. Nevertheless, the operating efficiency of that type of engine can be promoted in the reversed thrust mode of operation by so injecting gas or fluid into the bypass duct as to promote the attachment of air moved through that duct by the power plant fan to its inner surface.
