Since June 2014, the Aerospace Research and Test Establishment is actively involved in the project AFLoNext - "Active Flow Loads & Noise constrol on next generation wing".
The main objective is a project of using the active influence of the boundary layer on different parts of the aircraft to reduce resistance, noise and vibration. The project is coordinated by Airbus and includes 40 participants from 15 countries.
The project is divided into six areas VZLÚ participates in the following 4 areas:
TS1 Hybrid laminar flow control
In this part of the project department of Structural strength in VZLÚ tests resistance leading edge of the wing to the impact of a flying object (hail, bird).
TS2 Application flow control (AFC) on airframe
In this phase of the project the department of Aerodynamics in VZLU provides CFD flow calculations and optimization of active elements unaffected in the boundary layer (AFC) using pulsed blowing.
TS3 Application flow control in the engine pylon and wing
In this part of the project will be applied in the AFC technology pylon and wing, where due to the large bypass ratio of the engine is necessary to reduce the high lift devices on the leading edge.
TS4 Application flow control at the trailing edge of the wing
The last phase is focused on blowing near the trailing edge of the wing to move the boundary to buffeting at higher speeds.
AFLoNext aims to prove the engineering feasibility of the HLFC technology for drag reduction on fin in flight test and on wing by means of large scale testing.
The project will continue until May 2017.
