Abstract :
The authors investigate the suitability of holography as an optical flow diagnostic for turbofan nozzle flow structures. In this case a static 1/25th scale model of a powered turbo-fan nacelle has used for nacelle/wing integration studies and evaluated using a holographic technique. The holograms made show the core jet and the by-pass flow as it emerges from the nacelle nozzle system. They also show evidence of structural vibration at the by-pass nozzle wall. A comparison has also been made with alternative non-invasive diagnostic techniques
