Abstract
The present disclosure relates to an aircraft including two or more propulsive devices, and a fuselage integrated with a pair of wings to create a Blended Wing Body (BWB) structure, wherein an orientation of the fuselage and the pair of wings change based on a transition of the aircraft from a vertical position to a horizontal position. Further, each wing of the pair of wings includes a lower winglet and an upper winglet that are identical and coupled to each other at a wing tip. The aircraft further includes a plurality of elevons controlled by two or more propellers associated with the two or more propulsive devices.
Claims20
An aircraft comprising:
- an airframe including
- two or more propellers;
- a pair of wings;
- and
- a fuselage integrated with the pair of wings to create a Blended Wing Body (BWB) structure having a smoothly blended shape between the fuselage and the pair of wings, wherein the airframe transitions in flight between a vertical flight mode and a horizontal flight mode, wherein the BWB structure is designed such that over fifty percent of lift is generated from the fuselage of the BWB structure to allow for a reduction of a size of the pair of wings with respect to a size of the fuselage.
An airframe for an aircraft, the airframe comprising:
- a fuselage integrated with a pair of wings to create a Blended Wing Body (BWB) structure;
- and
- a pair of flaps coupled to the fuselage, wherein the pair of flaps is designed to facilitate at least one of take-off, landing, cargo securement, and a cargo release operation, wherein the pair of flaps exhibits two positions, comprising an extended position and a retracted position, and wherein the pair of flaps is configured to be in the retracted position during take-off and landing, ensuring ground clearance during landing and maintaining a spaced-apart position to prevent contact between the flaps;
- and
- two or more propellers, wherein the airframe transitions in flight between a vertical flight mode and a horizontal flight mode.
An airframe for an aircraft, the airframe comprising:
- a fuselage integrated with a pair of wings to create a Blended Wing Body (BWB) structure;
- and
- a pair of flaps coupled to the fuselage;
- and
- two or more propellers, wherein the airframe transitions in flight between a vertical flight mode and a horizontal flight mode, wherein the BWB structure is designed such that over fifty percent of lift is generated from the fuselage of the BWB structure.
