The RWD 17 was a Polish aerobatics-trainer aircraft of 1937, parasol wing monoplane, constructed by the RWD team.
The aircraft was designed for an order of the LOPP paramilitary organization, as an interim trainer aircraft between primary trainer RWD 8 and single-seater aircraft, demanding higher skills, like the RWD 10. It was also fitted to aerobatics. The construction of the new aircraft was very similar to the RWD 8, but almost all parts were newly designed. Main visual difference were twin struts supporting wings, instead of V-struts, and two-part wing instead of three-part, without central section. The works started in 1936, and the main designer was Bronisław Żurakowski of the RWD bureau. The first prototype (registration SP-BMX) was flown in August 1937 in Warsaw. After state trials in 1937, it was accepted for production, and in 1938 a short series of RWD 17 was produced (23 serial RWD 17 were in the Polish registry).
In early 1938, a floatplane variant RWD 17W was designed, differing among others in a more powerful 160 hp (120 kW) Bramo Sh 14a radial engine. It had interchangeable floats or land undercarriage. When on floats, a bigger tail-fin, extending downwards was mounted. The prototype was flown with a land undercarriage in June 1938, then tested on floats. Next, 5 RWD 17Ws were ordered for the Polish Naval Aviation Squadron (MDLot) at Puck, for use as trainers, built in 1939.
In early 1939 a new wing for the RWD 17 was developed, slightly longer, with thinner profile and narrowing wingtips. It gave better aerobatics capability. Because of problems with its counterpart PWS-35, the Polish Air Force got interested in the modified RWD 17 as a successor of the PWS-26 intermediate trainer; plans to order 50-120 aircraft, with a likely designation RWD 17bis, were not actioned due to the outbreak war.
