Lightweight design built to withstand the forces of gravity
Bucher Leichtbau AG
Lightweight design built to counteract the forces of gravity to the extent possible - Bucher Leichtbau, with production sites in Switzerland and the USA, is a master in this field.
Bucher Leichtbau develops and produces innovative lightweight solutions for civil aviation, air rescue and the automotive industry. The range of products comprises different fields of application, such as catering, cabin, emergency medical systems and automotive / VIP. Galleys and cabinets from Bucher Leichtbau are the ones most often used in civil aviation.
Such combined modules, also called "monument", can carry a net load of eight times their tare weight and have to withstand accelerations up to 9 times the acceleration due to gravity (9g).
Maintenance costs remain very low over the years because of the modular and rugged design. The required minimal service life is 25 years. However, galleys and closets need to prove their airworthiness prior to their first take-off.
A distinction is made between flight loads (regular flight loading conditions such as take-off, landing, turbulences, etc.) and emergency landing loads (controlled emergency landing or aborted take-off). Each of these loads is simulated on ground test facilities first. The galleys and cabinets are subjected to any occurring forces and accelerations (including the safety reserve) and their behavior under these loads is tested. Only after having successfully passed these tests will the monuments be approved for installation in aircraft by authorities, aircraft manufacturers or end customers (airlines).
