Study of a Lower-deck Galley for Airliners

The present work is concerned with the preliminary design of galleys for long-haul airliners. As usual approach galleys are located in the main deck of airliners or even in some few cases in the lower-deck cargo compartment. The present concept considers placing trolleys, items that occupy a siginifative room in galley installations, in the lower-deck and transport them to the main deck by a dedicated lift system. The main intention behind this proposal is to provide more room in the passenger cabin for accommodating additional passengers. By careful analysis that considers the necessary structural modifications the payoff of the present proposal is investigated. This was carried out by using the PADLAB ® 2.4 routine written for MATLAB ® and a in-house routine to evaluate performance and calculation of Direct Operating Costs (DOC) per seat mile. PADLAB ® is tailored to the design of the cabin and the device and systems aimed to operate the trolleys by the passenger cabin crew; the in-house routine was validated against data obtained for the category of airliners under consideration.
