Aircraft design |
| 摘要 |
The present invention is an aircraft wing design that creates a bell shaped span load, which results in a negative induced drag (induced thrust) on the outer portion of the wing; such a design obviates the need for rudder control of an aircraft. |

1. An aircraft that provides adverse yaw control without a rudder, comprising:
wings having a span load that changes from downwash to upwash at a location from about 60% to about 80% of the way from an aircraft centerline to a tip of the wings by providing a total wing twist percentage of about 10 times the aircraft's design lift coefficient to about 30 times the aircraft's design lift coefficient wherein from about 10% to about 35% of the total wing twist occurs from the centerline to about halfway to the wing tip and the remainder of the total wing twist occurs from about halfway to the wing tip to the wing tip. |
