The Stampe et Vertongen RSV.22[3] was a training biplane produced in Belgium in the 1920s.[4][5] It was a conventional, single-bay biplane with staggered wings of unequal span that were braced with N-struts near their tips.[6] The fixed undercarriage consisted of two mainwheels that were joined by a common through axle, plus a tailskid.[6] The student pilot and the instructor sat in open cockpits in tandem[4][6] that were fitted with dual controls.[2] Construction was of mixed materials, with metal used for the undercarriage, engine mount, and cabane struts.[2] The control surfaces were operated by a rigid linkage made of dural tube.[2] The horizontal stabilizer was adjustable in flight, using a lever in the cockpit to adjust the aircraft's trim.[2] Incorrect use of this latter feature led to a number of accidents.[2] The base model RSV 22/180 was powered by a 134-kW (180-hp) Hispano-Suiza engine, but the aircraft was designed to use powerplants of up to 220 kW (300 hp).[2] The RSV 22/200 variant used a 150-kW (200-hp) Renard-built radial engine in place of the Hispano-Suiza.[2][5]
The Belgian Air Force purchased 20 examples of the RSV 22/180.[2] In 1928, Lt Edmond Thieffry and SLt Philippe Quersin piloted a civil-registered RSV 22/180 (registration O-BAJE) on an attempt at a long-distance flight to Africa.[2] They departed Deurne on 26 June, attempting to reach Kinshasa.[2] Bad weather forced them to land at Mourmelon, France, only 230 km (140 mi) away. Resuming their journey, they were forced down a second time, this time in a marsh at Clapier, near Vauvert, still in France.[2] They abandoned the attempt at this point and successfully returned to Belgium.[2]

- ↑ Stampe et Vertongen designated their designs with two numbers; the first signifying the wing area of the design in square metres, the second signifying the power of the engine in horsepower (Hauet 1984, p.9). Stampe et Vertongen aircraft designed by Alfred Renard gained the prefix "R" (Hauet 1984, p.7).
