The Udet U 5 was a touring aircraft developed in Germany in the early 1920s. [1] [2] [3] It was found to be underpowered for its intended role, and only a single example was built. [3] However, its design served as the basis for the more successful Udet U 8. [3]
The U 5 was a parasol-wing, cantilever monoplane of conventional configuration. [4] It had a conventional tail, and fixed, tailskid undercarriage. [4] The pilot sat in an open cockpit, and an enclosed cabin could seat two passengers. [4] Power was provided by a radial engine in the nose, driving a two-bladed propeller. [4]
Construction was wooden throughout. [4] The fuselage was built of moulded plywood in an oval cross-section. [4] The wings had an almost elliptical planform and were mounted to the top of the fuselage on very short struts. [4] Unlike previous Udet designs that had a very angular fin, the U 5 had a fun with a curved leading edge, resembling the fins of Albatros aircraft of World War I. [4]
Construction of the U 5 was completed in July 1923, and it received the registration D.302. [3] Udet Flugzeugbau hoped to present it at the 1923 aeronautical exhibition in Gothenburg in August, but it was not ready in time. [3]
Apart from the overall lack of power, testing revealed that the aerodynamic fairings fitted to the cylinders of the radial engine made it prone to overheating, and these were removed. [3]
