The RemSchetMash RSM-15 Robust represents a Ukrainian-made, single-seat ultralight aircraft powered by a solitary engine. Its maiden flight occurred in 2006; however, by the end of 2009, no further units had entered production.
Design and development
This model is the sole aircraft produced so far by RemSchetMash, a company primarily engaged in general manufacturing. The Robust features a high-mounted wing with uniform chord and lacks flaps. Each wing is supported by a single strut connecting to the lower fuselage. The fuselage itself is constructed as a carbon fiber monocoque and includes a door on the starboard side for pilot entry into the one-seat cockpit. The landing gear follows a conventional tricycle undercarriage layout, with spring steel cantilever legs supporting the main wheels attached directly to the fuselage. Toward the rear, the underside of the fuselage tapers upward into the tail assembly, which consists of a constant chord horizontal stabilizer equipped with a one-piece elevator situated between two vertical endplate fins. These fins and their rudders feature parallel edges with rounded tips; notably, the rudders are shallower than the fins.
Propulsion is provided by a German-manufactured Hirth 2703 engine, delivering 41 kW (55 hp) from its twin-cylinder inline two-stroke configuration. This engine drives a three-blade propeller through reduction gearing.
The prototype, bearing serial number LA-0872, first took to the air in 2006. Similar to other Ukrainian ultralights such as the Lilienthal Bekas, agricultural spraying was evaluated as a potential application for this aircraft; nonetheless, no subsequent production models have been reported. An expanded variant named RSM-25 Bekas has been proposed, featuring an increased wingspan of 11.40 m (37 ft 5 in), a maximum takeoff weight of 495 kg (1,091 lb), and powered by an 80 hp (60 kW) Volkswagen 2300 air-cooled engine.
