Abstract:
A PARTICLE SEPARATOR, ESPECIALLY FOR USE IN CONNECTION WITH A GAS TURBINE, WHICH COMPRISES COWL MEANS HAVING AN INLET END AND OUTLET END AND TOGETHER WITH A DEFLECTOR BODY ARRANGED WITHIN SAID COWL MEANS IN SPACED RELATIONSHIP THERETO FORMS PASSAGE MEANS EXTENDING FROM SAID INLET MEANS TO SAID OUTLET MEANS WHILE THE OUTER CONTOUR OF SAID DEFLECTOR BODY ASCENDS FROM SAID INLET END TO A HUMP ON THE DEFLECTOR BODY BETWEEN SAID INLET OUTLET END, THAT PORTION OF SAID PASSAGE MEANS WHICH IS LOCATED BETWEEN THE OUTLET END OF SAID COWL MEANS AND THE SAID HUMP BEING DIVIDED INTO AN OUTER PASSAGE FOR DISCHARGING SEPARATED PARTICLE MEANS TO THE ATMOSPHERE AND TO AN INNER PASSAGE FOR DISCHARGING AIR TO A TURBINE ENGINE TO WHICH THE DEFLECTOR IS CONNECTED.
Abstract:
An inflating device having the character of a tip turbine type fan particularly adapted to enable a substantially instantaneous inflation of emergency life saving devices such as escape slides and life rafts. It features an improved nozzle configuration for receiving and delivering a small amount of high pressure air to a rotor assembly, in the operation of which the high pressure air is expanded and delivered as a high volume inflating medium, amplified by an ingested portion of ambient air. The rotor housing is distinguished by an inlet the form of which produces a smooth inflow of the ingested air and an outlet characterized by stator blades the mount of which avoids the problems normally anticipated where the device is subjected to extreme changes in temperature. The rotor outlet features a diffuser extension which contributes to its performance and increases its pumping efficiency.
