Abstract
Sposób polega na wykonaniu, w pierwszym etapie, modelu łopaty i na jego podstawie dwuczęściowej formy (4). W drugim etapie wykonuje się model rdzenia (3) łopaty, pomniejszony o grubość wzmocnień (6) ścianki łopaty, będące rozwinięciem lub rozwinięciami rdzenia (3). Na podstawie tego modelu wykonuje się dwuczęściową formę rdzenia (3), pokrywa się jej wnętrze środkiem zapobiegającym przyklejaniu się do niej rdzenia (3), zamyka się formę rdzenia (3) i wypełnia się ją żywicą utwardzalną spienialną. Po utwardzeniu, rdzeń (3) wyjmuje się i wykonuje się w nim kanały rozpływowe. W trzecim etapie wykonuje się wykroje warstw tkanin lub mat z włókien technicznych w postaci rozwinięć lub rozwinięcia rdzenia (3) stanowiące wzmocnienia (6) ścianki łopaty. Układa się te rozwinięcia w gnieździe jednej części formy (4) łopaty i na tak ułożone rozwinięcia kładzie się rdzeń (3). Części rozwinięcia lub rozwinięć są zawijane na rdzeń (3). Następnie zamyka się formę (4) i z jednej strony podłącza się do niej ciśnieniowy układ dozowania żywicy utwardzalnej konstrukcyjnej, a z drugiej strony podłącza się układ ssący wytwarzający podciśnienie w formie (4). Po utwardzeniu łopaty wyjmuje się ją z formy (4).The method consists in making, in the first stage, a model of the blade and, based on it, a two-part mould (4). In the second stage, a model of the blade core (3), reduced by the thickness of the reinforcements (6) of the blade wall, is made, which are an expansion or expansions of the core (3). Based on this model, a two-part mould of the core (3) is made, its interior is covered with an agent preventing the core (3) from sticking to it, the mould of the core (3) is closed and it is filled with a hardenable foamable resin. After hardening, the core (3) is taken out and flow channels are made in it. In the third stage, cut-outs of layers of fabrics or mats made of technical fibres are made in the form of expansions or expansions of the core (3) constituting reinforcements (6) of the blade wall. These expansions are placed in the socket of one part of the blade mould (4) and the core (3) is placed on the expansions arranged in this way. Parts of the expansion or expansions are wrapped around the core (3). Then the mold (4) is closed and a pressure system for dosing the hardened structural resin is connected to it on one side, and a suction system generating negative pressure in the mold (4) is connected on the other side. After the blade has hardened, it is removed from the mold (4).
