Golf clubs with improved aerodynamic properties. In an example, a golf club has a golf club head; a grip; and a shaft having a tip end and a butt end. The golf club head is coupled to the shaft at the tip end, and the grip is coupled to the shaft at the butt end. An average bending stiffness of a butt end portion of the shaft is greater than 3.70 times an average bending stiffness of a tip end portion of the shaft.

Shaft for golf club

Golf club heads with improved aerodynamic properties. In an example, the golf club head has a club head frontmost point and a club head rearmost point. The golf club head may include a striking face and a sole connected to a bottom side of the striking face. The sole has a rearmost point and may have a closing ascent angle of less than about 35 degrees. The club head also includes a crown connected to a topside of the striking face. The crown has a rearmost point and may have a closing descent angle of less than about 35 degrees. The closing descent angle may also be within 85%-115% of the closing ascent angle of the sole. Toeward and heelward tripping structures may also be incorporated on the hosel to further improve aerodynamic properties of the golf club head.

Low drag clubhead

A supersonic aircraft is disclosed herein. The supersonic aircraft comprises one or more fuselages, one or more wings, at least one wing-mounted engine, at least one inlet mounted on the upper surface of or above the wing, an upper wing surface propulsion system fairing, and a lower wing surface propulsion system fairing or lower wing surface modification to account for the presence of the engine.

A golf ball comprising a core comprising an inner core center and an outer core layer disposed over the inner core center. The inner core center has a deflection of greater than 0.210 inch under a load of 100 kilograms, and the entire the core has a deflection ranging from 0.130 inch to 0.105 inch under a load of 100 kilograms. A mantle layer is disposed over the core and a cover is disposed over the mantle.

Multiple layer golf ball

A golf club grip for a golf club includes an elongated member having a first end, a second end, an inner surface and an outer surface. The first end is configured to receive a golf club shaft. The second end includes a recessed opening. The recessed opening extends away from the second end longitudinally toward the first end. A sensor housing comprising a first portion and a second portion. The first portion is received within the recessed opening. The first portion couples the sensor housing to the elongated member. The second portion receives a removable housing therein.

Golf putter grip

A golf ball comprising a core comprising an inner core center and an outer core layer disposed over the inner core center. The inner core center has a deflection of greater than 0.210 inch under a load of 100 kilograms and the core has a deflection ranging from 0.120 inch to 0.090 inch under a load of 200 pounds. An inner mantle layer is disposed over the core, an outer mantle is disposed over the inner mantle layer, and a cover is disposed over the outer mantle.

Golf ball with dual core and thermoplastic polyurethane cover

A golf ball comprising a core comprising an inner core center and an outer core layer disposed over the inner core center. The inner core center has a deflection of greater than 0.210 inch under a load of 100 kilograms and the core has a deflection ranging from 0.120 inch to 0.095 inch under a load of 100 kilograms. A mantle layer is disposed over the core and a cover is disposed over them mantle.
