Abstract

Additional Cabin-Space for Cabin Systems: Cabin Operation below PAX floor level

These ideas will create more space for cabin related purposes. Special storage systems shall be located under the PAX floor. The stored elements might be accessible directly from the cabin. Several proposals for these special storage systems are made in order to enlarge the usable space below the level of the PAX floor.

There are several types of storage systems above and below the PAX floor. In known solutions complex systems access the storage space located under the PAX floor from the cabin side (e.g. a lift). Due to the systems' complexity only large storages under the PAX floor are efficient today. Large storages under the PAX floor normally reduce the freight volume because they are directly part of the cargo volume (e.g. new under floor catering system). Regrettably smaller storage capacities are unused.

With the following ideas even small spaces below the PAX floor can be accessed from cabin side. This allows the usage of the additional space below the PAX floor for cabin related purposes. Especially in the combination with a flat rear pressure bulkhead this additional space for cabin use is beneficial: It is an enabler for additional seats.

Due to the added space below the PAX floor level for cabin purposes it is possible to reduce the space consumption of e.g. galleys or lavatories and therefore generate more space for additional passenger seats and may lead to new cabin layouts.

Summary

This paper suggests the following solutions using several spaces under the PAX floor for cabin related purposes:

1. A "rotating rack" 2. Installation of cabin related systems under the PAX floor (e.g. the trolley cooling system) 3. A paternoster 4. A rack on a telescope guide rail, and 5. A storage box.

1. "Rotating rack".

The rack is formed like a circular arc of maximum 180°. It is hinged in two telescope guide rails. This guiderails are installed under the PAX floor. To be able to access this rack one floor panel is a hatch. This floor panel can be opened and the rack can be accessed. To be able to turn out the rack, one ending of the storage system has to be located between the floor beams. The rack can be loaded and unloaded when the hatch is in the opened position. For critical flight phases (like start / landing) the rack can be stored properly under the PAX floor. The advantage of this solution is that the storage doesn't limit the cabin space above the PAX floor when it's not needed. It can be installed in every infrequent used area (e.g. a galley area) to maximize the storage in the cabin.

In contrast to known solutions of rotating racks this solution has not a physical central axis. Known solutions have a physical central axis around which the racks are turned. In this embodiment the rack is placed in telescope guide rails that follow circular curves. Thereby, the PAX floor is totally flat when the rotating rack is stored away.
