LAGOON Landing Gear
The numerical investigation of the LAGOON geometry is important to understand fundamental aspects of noise generation in simplified landing gears. This geometry is a simplified, scaled version of the Airbus A320 nose landing gear that is representative of those encountered in civilian aircrafts. The efforts in this particular geometry are conducted by ONERA and several contributions from several groups around the world are presented in the context of the AIAA-BANC Workshop (Manoha, 2015) .

Realistic Landing gear
Realistic geometries of nose landing gears include several components and mechanisms that detach the turbulent flow and greatly increase fluid-structure interaction. Furthermore, several cavities and pin-holes are present and have resonance modes that radiate noise very efficiently, leading to tonal peaks in far-field noise spectrum. Understanding this complex flow behavior is crucial to design quieter landing gears in civilian aircrafts.
