Abstract:
A control system for selectively adjusting effective flow areas of an aircraft engine exhaust nozzle to change operational characteristics of the nozzle, the control system comprising:a chamber having a hollow interior, an upstream end, and a downstream end; a plurality of outlet passages at said downstream end and extending from the hollow interior of the chamber to sites within the exhaust nozzle; and an inlet extending from a pressurized air source to the hollow interior of the chamber at said upstream end for delivering a jet of pressurized air to the chamber, wherein the inlet is adjustable to steer said jet of pressurized air to selected one or more outlet passages of said plurality of outlet passages at said downstream end of the chamber for the delivery of air via said one or more outlets to corresponding one or more sites within the exhaust nozzle thereby to change the operational characteristics of the nozzle.
