Abstract
An aircraft cowling (20) is comprised of a cowling body (22), forward and aft bearings (24,25) disposed on the cowling body (22), corresponding sets of guides (29,30) disposed on and conforming with the shape of the aircraft (26), a screw fastener assembly (74), latches (82), and complementary interaction between the cowling edges (68,70) and aircraft edges (69,71) to provide lateral support for the cowling (20). The aft bearing (25) is comprised of two rollers (44) and two roller supports (46) which are disposed on the cowling body (22) in a manner permitting lateral motion and coupled by a shaft (50) with right-hand threads (56) on one end and left-hand threads (58) on the other end. The shaft (50), due to the opposing threads (56,58), restricts the roller supports (46) to convergent and divergent movements and prevents movement in a common direction, thereby providing lateral support to the cowling (20) during opening and closing.
