Abstract
The spiroid wing tip according to embodiments of the invention including a continuous segmental assembly having a closed loop frontal profile comprising a lower near vertical segment, a horizontal segment, a vertical segment, a second horizontal upper segment, and a near vertical segment. Accordingly to some embodiments of the invention, the spiroid profile is lowered with respect to the wing chord plane, such that a portion of the spiroid wing tip extends below the wing chord plane.
Claims23
A spiroid wing tip, comprising:
- an originating section and a terminating section of an enclosed loop forming a wing tip attachment end designed for attachment to an end of a wing such that a leading edge and a trailing edge of the wing tip attachment end are continuous extensions of a leading edge and a trailing edge of the wing, respectively;
- and
- an intermediate section between the originating section and the terminating section, the intermediate section traversing a chord wise plane of the wing tip attachment end, the intermediate section swept rearward with respect to the trailing edge of the wing tip attachment end.
An aircraft including a wing projecting from a body, the wing including a spiroid wing tip coupled to an end of the wing, the spiroid wing-tip comprising:
- a first generally planar section coupled to an end of the wing, the first generally planar section extending in a first plane;
- a second generally planar section coupled to the first generally planar section extending in a second plane angled with respect to the first plane;
- a third generally planar section coupled to the second generally planar section extending in a third plane angled with respect to the second plane and swept generally rearward with respect to the body of the aircraft;
- a fourth generally planar section coupled to the third generally planar section;
- extending in a fourth plane angled with respect to the third plane;
- and
- a fifth generally planar section coupled to the fourth generally planar section and the end of the wing, the fifth generally planar section extending in a fifth plane angled with respect to the fourth plane.
