Flap Gap Oscillatory Blowing on 2D and 2.5D Wing

Blog Article

Here we present preliminary results obtained in developing an active flow control system for highlift systems at advanced TRL level.The Electronic Speed Controllers work is based on theoretical and experimental workperformed in AVERT EU FP6 project where the oscillatory flap gap blowing system was designedand tested on a INCAS F15 2D wing model.Pressure data and global loads have been recorded fora complex evaluation of the basic flow control mechanism.In 2.5D test cases this work has beenextended so that the proposed system may be selected as a mature technology in the JTI Clean Sky,Smart Fixed Wing Aircraft ITD.

For this goal, new experimental setup was used and also updatedelectronics for the blowing system have been introduces.This was complemented by a newextension for the data acquisition system and visualization tools.Finally global correlations forbasic lift increments have been compared with the reference 2D case and analysed with respect tothe Wash Bag system efficiency.
