Fourth meeting held on ORINOCO project

The latest meeting of partners in the ORINOCO project, to discuss work carried out over the past eighteen months, was held on March 20–23, 2012 in the French city of Poitiers. Participating from the Russian side were specialists from TsAGI, CIAM, Aviadvigatel OJSC, GPI RAS, JIHT RAS and TRINITI along with project experts from leading aviation sector companies Tupolev JSC, Beriev Aircraft Company JSC and Sukhoi JSC. EU countries were represented by specialists from ONERA, CIRA, CNRS, ECL, NLR, UNIROMA TRE, ERDYN, and project experts from AIRBUS, SNECMA and ALENIA. The European Commission was represented at the meeting by Commissioner Eric Lecomte. The event was hosted by CNRS in Poitiers.

During their presentations, the participants in the project discussed in detail the results achieved and the problems encountered, including scheduling issues that have arisen between the Russian and European projects.

«In the first year and a half, new results were achieved that clearly indicate the fundamental feasibility of the main ideas of the project — the possibility of recognizing and controlling instability waves in the shear layers of fast jet flows, which was not clear at the start of the ORINOCO project," the director of the project from the Russian side, director of TsAGI’s aero-acoustics and aircraft ecology department, Victor Kopiev said.

The ORINOCO project, for which TsAGI is the coordinator in the Russian side, with ONERA as its European partner, is being implemented as part of a new format of cooperation between the Russian Ministry for Industry and Trade and EU countries. The main feature of the research program is its combining deep study of the fundamental problems of noise generation by high-speed jets with the development of new technology to control instability waves using plasma actuators. During the ORINOCO project, many scientific issues were brought up for the first time. So, the main concept of the project, proposed by TsAGI, is based on the idea of instability waves developing in the Shear layer and attempts to influence them. To influence these objects it is necessary to have effective plasma actuators, plans for which are being developed as part of the project.
