Title: DE-ICING SYSTEM FOR AN AIRCRAFT
Abstract:
The invention relates to a de-icing system for an aircraft, comprising at least one heat source (28) and at least one air discharging means (23) for discharging air in areas of the aircraft to be de-iced. The invention is characterized in comparison to the prior art in that the air discharging means is connected to an air-conditioning system (26) of the aircraft by way of an air heating device (30) for discharging air from a cabin of the airplane, wherein the air heating device is connected to the at least one heat source for heating the air of the aircraft cabin. The de-icing system according to the invention can de-ice wings without any additional energy, having not only an anti-icing function but also a de-icing function on the ground. The function of the de-icing system according to the invention could be advantageously supplemented in that used cabin air can also be utilized to increase the flow energy on the top side of the wings in order to delay a reversal or separation of the boundary layer and generally increase the lift or lower the resistance.
