The disclosure is directed to an improved aerodynamic helmet. The helmet has a continuous aerodynamic curvilinear front, side and top surfaces whereby the fluid flowing over and around the sides of the helmet flows in a substantially continuous flow direction from the forward curved area aft of a straight area at the greatest width or largest transverse dimensions of the helmet after leaving the surface influence thereof. The continuous transverse surface around the outer periphery of the helmet at or slightly aft of the greatest width area is provided with a fluid flow termination surface or trailing edge causing the normal direction of the fluid flow around the helmet to break loose from the surface of the helmet and continue in substantially the same direction after passing the termination or trailing edge thereby preventing turbulence to the flow rather than allowing the fluid flow to follow the surface and flow around a portion of the smaller dimension back surface of the helmet before separating therefrom which creates turbulence behind the helmet and unwanted lift thereto. The improved helmet lowers wind drag compared to conventional helmet by about 40%.
