DE-ICING SYSTEM FOR AN AIRPLANE

摘要

The invention relates to a de-icing system for an airplane, comprising at least one heat source and at least one air discharging means for discharging air in areas of the airplane 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 of the airplane by way of an air heating device 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 cabin of the airplane. The de-icing system according to the invention is capable of providing wing de-icing without any additional energy, wherein not only is an anti-icing function provided but also a de-icing function. The function of the de-icing system according to the invention could be advantageously supplemented in that cabin exhaust air can also be used to increase the flow energy at the top side of the wing in order to extend a boundary layer envelop and/or delay boundary layer separation and in general to increase the lift or lower the resistance.
