FVM J 23 and FVM J 24 (Fighters,1923-1926)

Page 1 (1)



Five J 23 interceptor fighters were built in 1923. The model was advanced for its time. The plywood-covered fuselage was self-supporting. The type was powered by a 260 hp Maybach engine. Due to a failure in the wing construction (bad gluing), which led to a fatal crash, the type was soon withdrawn. Photo above of J 23 # 3119.
An improved model, J 24, was designed by FVM and delivered in 1925. This model had a stronger engine, a 300 Hispano-Suiza. The machine was of heavier and stronger design than J 23, but this made the aircraft harder to handle. In a dive at the trials, the fuselage broke apart, but luckily the pilot managed to make a safe landing. Photo below.

After this accident, this monoplane was changed to a biplane with the designation J24B. Trials started in October 1925. But now a lot of time had passed. Cheaper foreign aircraft with similar performance could be obtained abroad. Only the prototype was built. Photo below.
