Optimization of APU Exhaust Muffler Thermal Barrier and Air Intakes construction Technologies

Topic description

Specific Challenge:

The purpose of this research topic is to develop :
- A new basic thermal barrier concept to be used in Exhaust Muffler that can be used in rear end fuselage or in other parts of the Aircraft where a power unit might be installed.
- A new basic materials construction concept to be used in Air Intakes that can be used in rear end fuselage or in other parts of the aircraft.
Air Intakes and Exhaust Mufflers are parts of the system installation required for air breathing engines (such as an Auxiliary Power Unit) or other Aircraft systems. These parts provide a flow path for the external air needed, as well as the exhaust gas path. They provide other functions such as fire barrier (meet Fire Proof requirements according AC 20-135), noise attenuation and thermal insulation.
