British Patent Abridgments

Abstract

In the jet propulsion plant installation in an aircraft wing each chordwise extending square tube 119 is attached to a splitter plate 114 by vertical dowel pins 115 and by bolts 116 passing through the tube and through a strip 117 attached to the splitter plate 114. A further strip 118 connects each tube 119 to the adjacent ram‐jet compartment cover 233. Spanwise extending stiffeners 227 on the adjacent turbojet compartment cover 230 are attached by fastenings 229 to brackets 231 secured to the tube by bolts 116, fasten ings 229 allowing spanwise thermal expansion. A strip 228 attached to the cover 230 lies on a joggled part of cover 233, also to allow thermal expansion. The tube 119 has a reinforcing web 119a. The joints 273 between the covers 230, 233 and the forward wing portion allow spanwise thermal expansion of the covers. The cover 233 is a sandwich comprising spanwise corrugations, and the splitter plate 114 has vertical corrugations. The cooling air which flows rearwardly through tube 119 is tapped off to flow through these corrugations through ports 119b, 119c respectively in the tube.
