Title: The Innovations of Richard Hall Lightfoot
Introduction
Richard Hall Lightfoot is a notable inventor based in New York, NY (US). He has made significant contributions to the field of anti-icing fluids for aircraft, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of aircraft operations during winter conditions.
Latest Patents
Lightfoot's latest patents include innovative formulations for aircraft anti-icing fluids. The first patent describes an anti-icing fluid that is a glycol-based, aqueous solution containing a hydrophobe-bearing, macromonomer-containing polymer thickener. This thickener is used in an amount of less than about 5 weight %. The thickening occurs predominantly through the association among hydrophobe groups. The fluid is designed to not adversely affect airfoil lift characteristics during takeoff, as it exhibits shear thinning and readily flows off the aircraft surfaces when exposed to wind shear during the aircraft's takeoff run.
The second patent also focuses on an anti-icing fluid suitable for ground treatment of aircraft. This formulation is a glycol-based solution containing a macromonomer-containing polymer thickener, again in an amount of less than about 5 weight %. This thickened deicing fluid promotes adherence to aircraft surfaces when applied to a stationary aircraft. Similar to the first patent, it does not negatively impact airfoil lift characteristics during takeoff.
