Abstract:
The present work is concerned with the preliminary design of a new galley concept for long-haul airliners. Usually, galley systems are placed in the main deck of airliners or even in some cases in the lower-deck cargo compartment. The present concept considers placing trolleys, components that occupy significant room in galley installations, in the lower-deck compartment and transport them to the passenger deck by a dedicated lift system. The main advantage of this proposal is that more room becomes available in the passenger cabin for the accommodation of additional passengers. By a careful analysis, which considers the required structural modifications that must be incoporated into the airplane configuration to accommodate the new concept, the payoff of the present proposal is investigated. This was carried out by using the PADLAB® 2.4 software package, written for MATLAB®, and an in-house routine to evaluate aircraftperformance and calculation of direct operating costs per seat mile. PADLAB® is tailored to the design of the cabin and the device and systems aimed at operating the trolleys by the passenger cabin crew; the in-house routine was validated against data obtained for the category of airliners under consideration.
