Abstract
The present application discloses an aircraft configured for vertical take-off and landing and horizontal flight. The aircraft includes a valve configured to control the permitting or restricting of a release of gas from different regions of a fuel tank when the aircraft is in a vertical take-off and landing orientation and when the aircraft is in a horizontal flight orientation.
Claims34
An aircraft, comprising:
- a first nacelle fuel tank configured to hold a first fuel supply for a first engine;
- wherein:
- the first nacelle fuel tank comprises at least a first venting module and a second venting module;
- and
- the first venting module and the second venting module are configured to provide venting from a top of the first nacelle fuel tank when the aircraft is in one of (i) a vertical take-off or landing orientation, or (ii) a horizontal flight orientation.

An aircraft, comprising:
- a fuselage fuel tank to hold a supply of fuel for a first nacelle fuel tank and a second nacelle fuel tank to power a set of engines;
- wherein:
- the fuselage fuel tank comprises at least a first venting module and a second venting module;
- and
- the first venting module and the second venting module are configured to provide venting from a top of the first nacelle fuel tank when the aircraft is in one of (i) a vertical take-off or landing orientation, or (ii) a horizontal flight orientation.
2 more elements
An aircraft, comprising:
- a left nacelle fuel tank to hold a first fuel supply for a left engine, the left nacelle fuel tank comprising a left venting mechanism;
- a right nacelle fuel tank to hold a second fuel supply for a right engine, the right nacelle fuel tank comprising a right venting mechanism;
- and
- a fuselage fuel tank to hold a supply of fuel for a first nacelle fuel tank and a second nacelle fuel tank to power the left engine and the right engine, the fuselage fuel tank comprising a fuselage venting mechanism;
- wherein:
- the left venting mechanism, the right venting mechanism, and the fuselage venting mechanism are configured to provide venting from a top of the corresponding fuel tank when the aircraft is in a vertical take-off or landing orientation, and when the aircraft is in a horizontal flight orientation.
