Overview

Background & policy context:

BUTERFLI responded to the invitation to tender from European Commission FP7 within Call FP7-AAT-2013 RTD-Russia. BUTERFLI is the acronym of BUffet and Transition delay control investigated within Europe-Russia cooperation for improved FLIght performances.

Objectives:

The Project focused on experimental and numerical flow control investigations of different phenomena: the buffet on a laminar airfoil, the buffet on a turbulent supercritical airfoil, and the cross-flow instabilities on a swept wing. Different control techniques will be studied: bump design, fluidic control devices, and DBD devices. The project aims at the improvement of aircraft flight performances.

This project will be carried out in the framework of a EUROPE – RUSSIA cooperation. ONERA is the coordinator, and TSAGI will act as Coordinator of the Russian Parties.
There are 12 partners, 7 from Europe and 5 from Russia.
ONERA (F), IAG-Stuttgart (G), DLR (G), KTH (S), University of Nottingham (UK), EADS UK Ltd. (UK), TsAGI (Russia), MIPT (Russia), JIHT (Russia), ITAM (Russia), Sukhoi Civil Aircraft (Russia), and Erdyn (F).

Methodology:

BUTERFLI is divided into four work packages:

  • WP1 is dedicated to buffet control on 2D turbulent supercritical wing (tangential jet blowing and plasma actuators);
  • WP2 is dedicated to buffet control on 2D laminar wing (bump and perforation blowing);
  • WP3 is dedicated to crossflow instabilities control on swept wing;
  • WP4 ensures the scientific coordination of the overall project, and will proposes final roadmaps for the future.
