Objective: Low-cost, lightweight, signature-oriented, thrust-vectoring exhaust system.
Approach: Eliminate moving parts to allow high-aspect ratio nozzle apertures and use fluidic injection for throttling & multiaxis vectoring.
- Necessary for LO exhaust system
- Compatible with aggressive cooling
- Thrust vectoring for improved control authority
- Significantly reduces LCC and TOGW compared to variable nozzles
Technology Prioritization: Selected Technology Set
Notes:
Conformal fluidic nozzles use air injection at key locations within the nozzle to provide flow throttling and/or thrust vectoring. Unlike conventional convergent flap nozzles, fixed conformal nozzles feature no moving parts and are designed to integrate with the aft structure of the aircraft providing significant airframe weight and cost savings. These design features also provide excellent low-observable characteristics without trading off flow throttling or vectoring performance.
