The Moskalyev SAM-5 was a 1930s Soviet transport or air ambulance monoplane designed by Aleksandr Moskalyev.[1] The type served in small numbers in the Second World War as an air ambulance.[1]
Development and design
The SAM-5 was a cantilever high-wing monoplane with fixed conventional landing gear and an enclosed cabin for a pilot and four passengers.[1] The first prototype was built using stressed-skin light alloy construction but it had problems with the quality of workmanship in what was an unfamiliar material.[1] The second-prototype SAM-5bis was built using plywood and fabric and had wing bracing and a more slender fuselage.[1] After testing 37 production aircraft were built and they were delivered from 1937 as air ambulances with room for three patients and an attendant.[1]
Moskalyev then worked on an improved variant, the SAM-5-2bis, tested with a 200 hp (149 kW) engine; the aircraft established distance and height records.[1] An order was placed for 200 of the improved variant, again for use as an air ambulance but they were never built.[1] This last SAM-5 variant led to four, differently numbered, developments.
