Aircraft with a subfloor region that accommodates an auxiliary compartment
First Claim
1. A rotorcraft with a fuselage, the rotorcraft comprising:
- a floor structure that is arranged inside the fuselage defining a subfloor region between the floor structure and a fuselage underside of the fuselage;
an equipment bay with at least one auxiliary equipment arranged within the subfloor region, the at least one auxiliary equipment being at least partly stowable in the equipment bay in a stow mode; and
at least one auxiliary compartment being at least partly arranged in a region between the equipment bay and the floor structure such that the at least one auxiliary compartment separates the equipment bay from the floor structure;
wherein the at least one auxiliary equipment is forcibly moved in the equipment bay by a crash load from a stow position associated with the stow mode into at least one crash position in the equipment bay to reduce force on the auxiliary equipment.

Abstract
An aircraft with a fuselage and a floor structure that is arranged inside the fuselage, the floor structure and the fuselage defining a subfloor region between the floor structure and a fuselage underside of the fuselage, the subfloor region accommodating at least one auxiliary compartment, wherein an equipment bay with at least one auxiliary equipment is arranged within the subfloor region, the at least one auxiliary equipment being at least essentially stowable in the equipment bay in a stow mode and the at least one auxiliary compartment being at least partly arranged in a region between the equipment bay and the floor structure such that the at least one auxiliary compartment separates the equipment bay from the floor structure.

17. An aircraft with a fuselage, the aircraft comprising:
-
a floor structure that is arranged inside the fuselage defining a subfloor region between the floor structure and a fuselage underside of the fuselage, wherein the subfloor region is provided with a crashworthy frame structure defined by transversal frame components and longitudinal frame components; an equipment bay arranged within the subfloor region; at least one auxiliary equipment at least partly stowable in the equipment bay in a stow mode, the at least one auxiliary equipment comprising a shaft that is mounted to the predetermined transversal and/or longitudinal frame components of the frame structure with structural frame attachments; at least one auxiliary compartment being at least partly arranged in a region between the equipment bay and the floor structure such that the at least one auxiliary compartment separates the equipment bay from the floor structure, wherein at least one of the structural frame attachments is provided with a crash fuse mount that holds the shaft, the crash fuse mount being adapted for absorbing energy in a crash load case. - View Dependent Claims (18, 19)
