In the absence of a direct line-of-sight to exhaust surfaces, the interaction of the exhaust plume with the airframe can make a significant contribution to the infrared signature of a gas turbine powered aircraft. A detailed study at full scale usually involves high complexity and cost. A smaller scale system based on a micro gas turbine offers the opportunity to reduce cost and complexity, while maintaining realism due to the similarity to actual full scale engines of the speed, temperature and composition of the exhaust plume. This paper presents the characterisation of a real gas engine plume in a small scale facility and preliminary results of its surface heat interaction with aluminium samples. Experimental plume characterisation and surface heating results were found to agree to some extent with Computational Fluid Dynamic (CFD) plume predictions.

|Other||The Australian Division of the Royal Aeronautical Society is co-hosting the 16th Australian International Aerospace Congress (AIAC16), 24-26 February 2015. Australia’s premier aerospace forum will take place at the Melbourne Convention Centre, with two half day meetings on site at the Avalon Airshow.|
AIAC16 will facilitate three technical conferences:
16th Australian Aeronautical Conference
8th DSTO International Conference on Health and Usage Monitoring (HUMS 2013)
2nd International Conference on Near Net Shape Manufacturing.
The AIAC16 will be re-convening on-site at the Airshow on the mornings only of Wednesday 25 and Thursday 26 February 2015.
