Abstract
1,253,659. Cooling duct for gas turbine engine. ROLLS-ROYCE Ltd. 16 June, 1969 [15 May, 1968], No. 22989/68. Heading B7G. [Also in Division F1] Exhaust gases from a gas turbine engine 12 (Fig. 1, not shown) are guided through a conduit 16, Fig. 2, enveloped by a casing 24, to turbine blades 18 situated at the radially outer extremities of blades 20 of a lift fan (22). Casing 24 forms with conduit 16 induction nozzles 28, 30, and air passing through inlet 34 forms a low pressure area adjacent nozzle 28, so that ambient air at atmospheric pressure is induced to flow through apertures 17 in the casing 24 and along the annular space 26 defined thereby to fill the low pressure area, where it is entrained in the airflow through inlet 34, thus providing a constant cooling flow around the conduit 16. Also, the hot gases passing out of fan turbine duct 32 create a low pressure area adjacent nozzle 30, and some of the ambient air is induced to flow through nozzle 30. The sizes of apertures 17 may be varied relative to each other, and baffle-shaped members may be placed in the annular space 26 as an air flow control.
