Title
(EN) HEATING ELEMENT
(FR) ELEMENT CHAUFFANT
Abstract
(EN)
An electrically powered heating element (1, 2) for a propeller blade is made up of a mat of fibres having at least surfaces which are electrically conductive. The mat can have a perforated backing to which it is fixed by adhesive. Methods of producing the heating element and fixing the heating element to a propeller blade involve a curing step for bonding the mat and backing using the adhesive.
(FR)
Elément chauffant (1, 2) alimenté par l'énergie électrique, destiné à une pale d'hélice, et composé d'une enveloppe de fibres possédant au moins des surfaces électroconductrices. Cette enveloppe peut posséder un support perforé auquel elle est fixée à l'aide d'un adhésif. Des procédés de production de l'élément chauffant et de fixation de celui-ci sur une pale d'hélice impliquent une étape de durcissement afin de lier l'enveloppe et le support à l'aide de l'adhésif.
