Abstract

The invention relates to a rotor blade heating system which can be used particularly for wind power stations, whereby the rotor blades (2) thereof are embodied with a cavity (1) and consist of an electrically non-conductive material. According to the invention, the cavity (1) of each rotor blade (2) has a rotor blade heating system in the form of an electrically conductive heating layer (3) which is adapted at least occasionally and/or at least periodically to the geometry of the cavity (1).

Description

Die Erfindung betrifft eine Rotorblattheizung durch Wärme und infraroter Strahlung (FIR). The invention relates to rotor blade heating by heat and infrared radiation (FIR).

Bekannt sind u. a. Luftgebläseheizungen bei denen Luft in einem Register elektrisch erwärmt wird und von einem Gebläse durch Kanäle auf einer Hälfte des Rotorblattes hin und auf der anderen Hälfte des Rotorblattes zurückgeführt wird. Der technische Aufwand hierfür ist sehr groß und wird umso größer, je länger und breiter die Rotorblätter sind. Are known a. Air blower heaters where air in one Register is heated electrically and by a blower through ducts on one half of the rotor blade and on the other half of the Rotor blade is returned. The technical effort for this is very large and gets bigger the longer and wider it is Rotor blades are.

Die folgenden Patentansprüche zeigen, daß die Erfindung von mir ohne großen technischen Aufwand durchführbar ist und einfach in das Rotorblatt eingebaut wird. The following claims show that the invention is mine is feasible without great technical effort and is simply in the rotor blade is installed.
