A frame for reinforcing a hull of a craft, particularly an aircraft, contains at least one frame element that is shaped in accordance with the curvature of the hull and has recesses at a side facing the hull for the passage of longitudinal beams of the craft. Each frame element is integrally formed from a fiber-reinforced plastic composite material and the recesses are configured as integral cut-outs of each frame element.

Frame and method for producing such a frame

The invention relates to a guide-vane arrangement () for deviating the flow present in the by-pass flow channel () of an engine (), said arrangement comprising an outer ring () and an inner ring () and guide vanes () arranged therebetween in a substantially radial manner, wherein the outer ring () has elements () for connecting to an outer engine structure (), and the inner ring () has elements () for connecting to an inner engine structure (), with a plurality of segments () being provided. In order to create a guide-vane arrangement () which is sufficiently stable and has optimum aerodynamic properties, each segment () is integrally produced from at least one guide vane () with a part () of the outer ring () having at least two flanges () for fixing to the outer engine structure (), and with a part () of the inner ring () having at least two flanges () for fixing to the inner engine structure (), the segments () preferably being made of fiber-reinforced plastic composite material, preferably by an RTM (resin transfer molding) method.
