NCAR In Situ Eddy Dissipation Rate (EDR) Algorithm

Problem: The National Center for Atmospheric Research (NCAR) and the FAA needed to flight test and optimize their in situ turbulence severity estimation algorithm.

 

Approach: AeroTech implemented the NCAR/FAA algorithm for testing on the highly instrumented NASA Boeing 757-200 research aircraft. This required the “tuning” of the algorithms for this particular aircraft. In addition, AeroTech implemented improvements in the algorithm, as well as developed another version based on a completely different approach.

 

Results: The NCAR/FAA algorithms were subjected to turbulence on an experimental aircraft for the first time. The newer versions of the algorithms performed better overall – less susceptible to false estimations. The changes and improvements developed by AeroTech have subsequently been adopted in a wider implementation of this algorithm by NCAR and the FAA.

AeroTech Contributions: Algorithm development and refinement, aircraft and algorithm simulation, flight test development, and data analysis. AeroTech also designed and directed the flight test plans.
