Here is a brief summary of the various projects designed by Jean de Wouters d'Oplinter. None was built unless mentioned:
- type A, 1923, single seat light monoplane with a thick cantilever wing and one "propulseur trompe" engine (maybe a sort of early jet engine like those by Mélot)
- type B, 1923, two seat twin boom light monoplane with a thick cantilever wing and two "propulseur trompe" engines
- Bat, late 1920s, various design concepts for a two-engine bomber, some of them with twin booms
- biplane, late 1920s, single seat light biplane
- Oplinter 50, late 1920s, single seat light parasol monoplane
- ARA, 1931, single seat parasol monoplane with Salmson 9Ad 40hp engine, construction was well advanced in the Guldentops workshops but it was never finished, registration OO-ARA was apparently planned but not officially given
- Arrian, 1932, glider
- type 25, 1932, glider
- glider with elliptical wing, early 1930s, flying wing design
- flying wing motor glider, early 1930s, another flying wing design with pusher engine
- type 10 mètres, 1932, single seat low wing monoplane, Salmson 9Ad 40hp engine, the first aircraft would have reused the fuselage of the ARA
- Wielemanns III, 1932-33, a derivative of the type 10 mètres with Gipsy 120hp engine, that would have been built by Robert Wielemanns
- Squale, ca. 1932, low wing monoplane with maybe retractable gear, two seats in tandem, the front one being maybe enclosed in a sort of cabin
- biplane military trainer, ca. 1933, maybe intended to compete with the Stampe SV.5, Renard R.34 and LACAB T.7
- Long Courrier or Air Taxi, 1933, cabin monoplane with tricycle gear and two Gipsy Major 135hp pusher engines. Guy Roberty mentions that the same configuration was found on a 1936 Tipsy project with two AVA 25hp engines, and on the Régnier 22 (two-seat), 23 (three-seat) and 24 (four-seat) projects dated ca. 1937-38, but it is not known if these were designed or influenced by Wouters.
- parasol monoplane, mid 1930s, two seats in tandem and folding parasol wing
- Lark 1, ca. 1934-35, single seat low wing monoplane, precursor of the Tipsy S
- Lark 10, mid 1930s, evolution of the Lark 1 with high aspect ratio wing, single wheel or conventional landing gear
- Lark IIa, b, c, 1937, single seat shoulder wing monoplane with pusher engine
- A-8, ca. 1937, single seat high wing monoplane with pusher engine ; it has an unusual configuration with no vertical tail and vertical surfaces at the end of the wings
- single engine pusher, mid to late 1930s, shoulder wing monoplane with a single engine inside the fuselage driving two pusher propellers
- Oplinter W.4, 1937, low wing monoplane with two seats side by side in an enclosed cabin, built and flown with registration OO-ARV
- S.E.A. 3, 1939, variant of the W.4 built by Peetermans, of which three examples were started. According to Les Ailes 20 Jul. 1939, two aircraft were exhibited at the 1939 Bruxelles Salon, but these perhaps included the original W.4 prototype.
- S.E.A. 4, ca. 1939, larger and more powerful version of the W.4 for military training, perhaps corresponding to a drawing by Wouters of a W.4 with six-cylinder engine and retractable gear
- twin engine W.4, ca. 1939, three seat cabin aircraft
