590,511. Aircraft. BUDD MANUFACTURING CO., E. G. Oct. 17, 1944, No. 20069. Convention date, June 23, 1943. [Class 4] In a hollow body, such as the body 20 of an aircraft shown in Fig. 1 and particularly one with side wall openings 31 giving access to the body cargo space, members, such as the wings 19, span the openings and provide reinforcement to the side walls, which are liable on landing of the aircraft to bulge at the curved parts of the side walls as shown at f in Fig. 3. The primary wing attachments through spars 39, 40 shown in plan, Fig. 4, are constructed in the manner described in Specification 590,510, these attachments being forward of the openings 31 ; the lighter secondary attachments for the trailing wing portions span the door openings 31 to serve as external reinforcements, The wing 19, Fig. 8, with reinforced upper and lower skins 38 is connected by the reinforcing stringers 42 to the curved wall members 35, the skins 38 being connected by filler sections 47<1> to the body skin 33. The two sets of attachments are indicated by shading in Fig. 4 to show the C-shaped reinforcing member formed by them.
