Abstract
An aircraft with a fuselage that accommodates a floor panel and a fuel storage system, wherein the fuel storage system comprises a tank system with at least one main tank 5a that is arranged underneath the floor panel; a cross ventilation system with a plurality of ventilation lines for venting the tank system, wherein the plurality of ventilation lines comprises at least one crossing ventilation line 11a that is routed from a first lateral side of the tank system to an opposite second lateral side of the tank system; and wherein the at least one crossing ventilation line is routed underneath or in the floor panel from the first lateral side of the tank system to the second lateral side of the tank system.
Claims12
An aircraft with a fuselage that accommodates a floor panel and a fuel storage system, wherein the fuel storage system comprises:
- a tank system with at least one main tank that is arranged underneath the floor panel in the fuselage;
- a cross ventilation system with a plurality of ventilation lines for venting the tank system, wherein the plurality of ventilation lines comprises at least one crossing ventilation line that is routed from a first lateral side of the tank system to an opposite second lateral side of the tank system;
- wherein the at least one crossing ventilation line is routed underneath or in the floor panel from the first lateral side of the tank system to the second lateral side of the tank system;
- and wherein the floor panel defines a floor panel level;
- and
- a manifold connection that is connected to the plurality of ventilation lines, wherein the manifold connection is arranged above the floor panel level of the floor panel,
- wherein the at least one crossing ventilation line is routed underneath or in the floor panel from a first ventilation point provided at the first lateral side on the at least one main tank to the manifold connection that is arranged at the second lateral side.
A fuel storage system for an aircraft with a fuselage having a floor panel, wherein the fuel storage system comprises:
- a fuel tank system having at least one fuel tank arranged underneath the floor panel in the fuselage;
- a cross ventilation system comprising:
- a manifold connection arranged above the floor panel;
- and
- a plurality of ventilation lines interconnected at the manifold connection for venting the at least one fuel tank and having at least one crossing ventilation line that is routed from a first lateral side of the tank system to an opposite second lateral side of the tank system,
- wherein the at least one crossing ventilation line is routed underneath or in the floor panel from the first lateral side of the tank system to the second lateral side of the tank system, and
- wherein the at least one crossing ventilation line is routed underneath or in the floor panel from a first ventilation point provided at the first lateral side on the at least one fuel tank to the manifold connection that is arranged at the second lateral side.
