A system for jet engine noise control of a jet engine having a main jet stream exiting an exhaust nozzle and flowing along a jet axis includes a thermal acoustic shield directed at a non-zero angle relative to the jet axis. The thermal acoustic shield may be configurable about the main jet stream. The system may further include at least a fluidic chevron injected at a location relative to the nozzle exit for enhancing mixing in the main jet stream and creating a non-circular jet stream.
What is claimed is: 1. A system for jet engine noise control of a jet engine having a main jet stream exiting a nozzle exit and flowing along a jet axis, the system comprising: a plurality of vortex generator jets configured to inject a plurality of jets of fluid at reconfigurable locations relative to the nozzle exit during different stages of a mission for creating a non-circular jet stream. 2. The system of claim 1 comprising between 16 and 32 vortex generator jets. 3. The system of claim 1 wherein at least one jet of fluid is injected at an ang...
