Tests of air curtain in AWB on the LAGOON and the the GB-TA-MLG Landing Gears
September 1st, 2022
Trinity College Dublin, has successfully developed and tested a range of "air curtains" to reduce the aerodynamic noise from landing gear. The air curtain acts as a fluidic spoiler which uses locally mounted compressed air nozzles to redirect the airflow around the solid surfaces of the landing gear hence shielding it in a low-velocity lee. The configurations were initially examined using a RANS & DES 3D CAA numerical model before being designed with a Solid Modeling CAD software and then fabricated using both 3D printing and by machining aluminum parts. The novel air curtain configurations were tested on a scaled Landing Gear developed in the INVENTOR project in the AWB wind tunnel of DLR in Braunschweig.
