TsAGI and NASA to Acquire Data to Improve Methods of Computational Aerohydrodynamics

4 September 2013


At the MAKS-2013 on 28 August TsAGI and NASA signed an agreement to conduct cooperation on the acquisition of data for computational fluid dynamic method validation and wind tunnel facility comparison.

In the agreement the parties express a mutual interest to collect complementary and unique data on the NASA common research model (CRM) with the goal of validation and improvement of computational fluid dynamics methods (CFD) and also for comparison of existing data obtained in the National Transonic Facility (NTF) at Langley Research Center (LaRC) and the Transonic Wind Tunnel (TWT) at Ames Research Center (ARC), to data to be collected during the CRM testing in the TsAGI wind tunnel.

The NASA CRM is a modern, publicly available, subsonic civil transport aircraft geometry. Data are in the public domain, with a subset used as the basis of two American Institute of Aeronautics and Astronautics CFD drag prediction workshops that included substantial international participation.

The test will be performed in TsAGI T-128 wind tunnel that is a continuous-running, variable density wind tunnel designed to research aircraft models at subsonic, transonic and supersonic velocities. NASA will provide the wind tunnel model, a model support and a force balance. The work is planned for 2014-2015 timeframe.
