A motorcycle fork rake extension kit provides an increased fork rake without welding and maintains a favorable trail. The extension kit includes an upper adapter block fixedly attached to an upper end of a steering head of a motorcycle frame and a lower adapter block fixedly attached to a lower end of the steering head of the motorcycle frame. Triple trees are rotatably attached to triple tree ends of the adapter blocks through steering head bearings. The triple tree ends of the adapter blocks are spaced away from the frame, the lower adapter block having a greater spacing to increase fork rake. The lower triple tree may further space the fork tubes forward to further increase fork rake. In a preferred embodiment, approximately 45 degrees of rake is provided with favorable trail.

A motorcycle helmet lock securely grasps a metal strap ring (or D ring) of a helmet strap to prevent helmet theft. The helmet lock includes a groove suitable to accept the strap ring and a locking bolt to advance through the strap ring to secure the helmet. The lock may be an integral part of a motorcycle grip or foot peg, may bolt to a common accessory attachment interface of known motorcycle grips, or include an expanding portion which expands inside a tubular handlebar end to attach the helmet lock. The lock may further be used on any type of vehicle using handlebars for foot pegs.

An aircraft with a variable forward-sweep wing and the method of configuring the wing in an optimal position for a desired flight regime. The variable forward-sweep wing is positionable from an essentially unswept position to a full-forward sweep position. In the unswept position the wing is approximately orthogonal to a fuselage centerline, while in the full-forward sweep position the wing has approximately a delta wing planform. Moreover, as the wing position changes from the unswept position to the full-forward sweep position the trailing edge becomes the leading edge. In addition, the aforementioned apparatus may be used in a method to configure the aircraft for flight in a desired flight regime. This method includes moving the wing to an optimal position for the desired flight regime.

An aerodynamic control system for an aircraft comprises a pair of low-aspect-ratio strakes integral with the fuselage, each of the strakes being substantially co-planar with an associated one of the wings and extending between a leading region generally blended with the trailing edge of the wing, a trailing edge and an outer edge. An aft airfoil is pivotally mounted to the trailing edge of each of the strakes movable between an extreme positive angle of attack position and an extreme negative angle of attack position. The aft airfoil includes an inner airfoil member which is laterally coextensive with said trailing edge of said associated strake and an outer airfoil member integral with the inner airfoil member which extends laterally beyond the outer edge of the associated strake. In one embodiment, the outer and inner airfoil members are substantially co-planar. In other embodiments, the outer airfoil member may be canted either upwardly or downwardly with respect to the inner airfoil member. In still other embodiments, the trailing edges of the strakes may either extend substantially perpendicular to the longitudinal axis of the fuselage, or extend forwardly or rearwardly with increasing distance away from the fuselage. Also, the strakes may have the construction of chines which are smoothly blended with the outer surface of the fuselage.

High lift producing apparatus for an aircraft includes a pair of foreplanes, one for each side of the aircraft, each foreplane extending between a root end at the fuselage and a distant tip end. Wings are mounted on the fuselage aft of the foreplanes and, intermediate the wings and the foreplanes, are a pair of strakes which are generally coplanar with their associated foreplanes and strakes, a leading edge of each strake being substantially coincident with a trailing edge of its associated foreplane, and a trailing edge of each strake being substantially coincident with a leading edge of its associated wing. The span of the strakes is smaller than the span of the foreplanes at the location of intersection of said strake and said foreplane. Each foreplane may be pivotally mounted on the fuselage at its root end on a stationary hinge axis which is substantially parallel with the longitudinal axis of the aircraft. The foreplanes are thereby movable between inactive positions flush with a contoured outer surface of the fuselage and deployed positions at which tip ends are distant from the fuselage. The foreplanes may also be pivotally mounted on lateral axes for control purposes. In one instance, the foreplanes can be simultaneously moved in the same direction about their associated lateral axes to achieve pitch control of the aircraft; in other instances, they can be independently moved about their associated lateral axes to achieve either yaw control or roll control.
