FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering and concerns development of streamlined structures for aircraft (AC) from polymer materials (PM), in particular, wings and semi-finished products for their manufacture. Disclosed is a method for manufacturing a semi-finished product of a wing panel, having skin in cross section, consisting of a front edge, a curved upper wall, a rear edge, a curved lower wall, vertical stiffeners serving as spars, at which the product is obtained by extrusion of polymer material through the die of the profile corresponding to the finished product. At the same time, co-extrusion of protective film is performed simultaneously with extrusion of the product.
EFFECT: possibility of obtaining an article by extrusion of polymer material through a die of a profile corresponding to the finished article.
