Abstract: Disclosed is a vertical rudder control system for an aircraft. The system is comprised of a rudder trim compensation generator that is configured to generate a rudder trim compensation order to set the position of the rudder bar of the aircraft to a neutral position in which the rudder bar is controlled with nil (i.e., zero) pilot effort. The vertical rudder control system includes a flight control calculator for calculating rudder control orders to maintain the nil effort rudder bar position, with the calculation of the rudder control orders being based on a sum of the rudder bar position, determined by a detection unit, and the rudder trim compensation order. The rudder control orders are received by a rudder operating unit, which is used to deflect the vertical rudder by a deflection value based on the rudder control orders.
Abstract: Embodiments relate to a method of fabricating a nano-sized structure in a resin element by nanoimprint lithography (NIL). The method reduces adhesive failure during NIL demolding by inhibiting polymerization at the interface between the resin element and the template. The template includes a polymerization inhibiting compound. The method includes pressing the template onto the resin element (or the resin element onto the template) to form the nano-sized structure in the resin element. The method also including diffusing the polymerization inhibiting compound from the template to the resin element, e.g., by holding them together for a period of time. A layer of the polymerization inhibiting compound is therefore formed at an interface of the template and resin element. The polymerization inhibiting compound inhibits polymerization at the interface. After the diffusion, the resin element is cured. Then the template is removed from the resin element.
