Capabilities
Please download the brochure below for more background about APPL and its capabilities.
APPL is equipped with several state of the art experimental rigs, diagnostic instrumentation, and infrastructure. For more detail on any of these see below:
- Studies sand ingestion in aircraft engines and interaction with engine hardware
- Operating temperature – 1500 Kelvin (atmospheric pressure)
- Sand velocities of 100 m/s targeted
- Sand deposition and restitution is measured.
- Capable of continuous operation with pressure up to 10 bar at a flow rate up to 1.2 kg/s
- Capable of turbine inlet temperatures of 1700°C
- Water quench system to cool exhaust gas before back pressure valves
- 3 – 5x8” Rectangular optical access windows at dump plane
– Heat Transfer and aerodynamic performance of engine hardware is studied in the transonic regime.
– IR thermography used to measure heat transfer in external flow (endwall, blade surface etc)
– Blowdown facility. Operates at 10 lbm/s for 30 seconds.
- Rig provides an open electrically heated jet (700 °F)
- Variety of experiments performed, e.g., acoustic studies to understand aircraft sound pollution, effect of vertical takeoff/landing on ship decks, acoustic thrust measurement etc.
- Instruments include stereo-PIV, time-resolved DGV, time-resolved schlieren, background-oriented schlieren, scattering and extinction particle diagnostics, and IR thermography.
– Operates at Mach 2-7
– Blowdown facility, run time of approximately 2s.
– Electric heater (220/380 V) with capacity 15 – 20 kW provides the flow stagnation temperature up to 800 K to prevent condensation of air at hypersonic speeds.
– Research and Instructional use
