LEGATO

In the LEGATO joint project funded by the German Federal Ministry of Economics and Climate Action (BMWK), project partners from industry and science are developing technologies to reduce noise, emissions and resource consumption over the entire undercarriage product life cycle. In addition to classic landing gear topics such as actuation, production and repair, the focus is for the first time on noise generation on the undercarriage. The aim of the project is to establish a digital process chain for identifying and avoiding or mitigating acoustic sources on the nose and main landing gears of short- and medium-range aircraft. In a digital process chain, acoustic sources are first identified on a landing gear using numerical methods (Computational Aero Acoustic (CAA)). Based on this, the project partners develop noise reduction concepts and investigate their effectiveness. The primary focus of the research is on changes to the shape of landing gear components or modifications to the landing gear architecture.
