Isolated Nacelle + Air Data System Calibration
PASSENGER + COMMERCIAL AIRCRAFT
PRESSURE & LOAD DATA
The Isolated Nacelle test technique is utilized by airframe innovators to better understand pressure and loads of this component over the flight envelope. Through the use of Calspan’s Subsonic/Transonic Wind Tunnel, Calspan’s wind tunnel experts can acquire surface pressure measurements from an isolated engine nacelle and analyze the pressure distributions resulting in forces and moments. This vital data is then used by aerodynamicists to determine:
- Satisfactory Inlet Shape
- Internal Flow Characteristics
- Surface Pressure Distribution
- Internal Pressure-Survey Rake Data as well as Engine Distortion Calculations
- Steady and Unsteady Pressures
- Power Spectral Density
AIR DATA SYSTEMS
Through the execution of Air Data System Calibration tests within Calspan’s Subsonic/Transonic Wind Tunnel, air data probes, as well as conformal air data systems, can be calibrated and analyzed. This critical data can then be integrated into a customer’s flight controls. This test technique can be used to:
- Improve probe shape/size of unconventional aircraft configurations.
- Study pressure differential and sideslip with respect to angle of attack.
- Optimize pressure port locations.
