Molding tool and method for manufacturing a fiber reinforced plastic aerodynamic aircraft component
A molding tool for manufacturing a fiber-reinforced plastic aerodynamic aircraft component, which aircraft component, in order to form several bays arranged on the inside and delimited by an outer skin and spars arranged spaced apart from each other, in each case includes a multi-part mold core that matches the shape of the respective bay, wherein to conform to local skin reinforcements and/or spar reinforcements that extend into at least one of the bays, the multi-part mold core includes four or five core parts, of which two core parts comprising a triangular cross section are arranged along opposing edges of the bay, which edges interact with two or three core parts that fill the space between the two triangular core parts, which space extends diagonally relative to the bay.
1. A molding tool for manufacturing a fiber-reinforced plastic aerodynamic aircraft component comprising:
first and second core parts each having a triangular cross section and configured for arrangement along a first set of opposed edges of a bay disposed within the fiber reinforced plastic aerodynamic aircraft component, the bay delimited by an outer skin and a plurality of spars; and
third and fourth core parts each having a pentagonal cross section and being configured to interact with a second set of opposed edges of the bay and fill a diagonally extending space formed between the first and second core parts when the first and second core parts are arranged along the first set of opposed edges of the bay, the third core part having surface grooves defining a first ramp-shaped chamfer corresponding to a second ramp-shaped chamfer of a skin reinforcement of the outer skin or spar reinforcement of one of the plurality of spars, the first ramp-shaped chamfer being sloped such that the second ramp-shaped chamfer allows removal of the third core part from the diagonally extending space in a direction transverse to the second ramp-shaped chamfer.
