Under the Shark's skin

摘要

The Shark was a three-person, unequal-span biplane powered by a 14-cylinder Armstrong Siddeley Tiger or a nine-cylinder Bristol Pegasus air-cooled radial engine. The fuselage was built in three sections. The forward section was a tubular steel frame attached to the firewall at the aft end, with a circular frame at the forward end on which the engine was mounted. The aft section bore the empennage and tailwheel. It was built up with sheet metal bulkheads reinforced with channel sections and ring frame, with U-section stringers, and skinned with Alclad. The main section was constructed of built-up frames connected with U-section stringers and skinned in Alclad. It extended from the firewall at the nose to the transport joint with the tail.
