Good afternoon, guys!
Some aircraft from the 1930s:
An American all-metal biplane, Meyers OTW (acronym of "Out To Win"), equiped either with a Warner 125 or 145 hp 7-cylinder radial engine or a 5-cylinder 160 hp Kinner radial aeroengine. Despite being well liked, only a little more than 100 airplanes were built and sold. Today, less than 5 OTW remains in airworthy condition.
VL Tuisku was finnish biplane trainer, built with welded steel tubes in the fuselage, with wooden wings and covered with fabric with the exception of the nose. Motorized with a British Armstrong Siddeley Lynx IV C 7 cylinder radial engine, capable of an output of 215 hp. 31 were built in 2 batches for the Finnish Air Force, and used as trainer and liaison aircraft during the Winter War and also during the Continuation War. Tuisku was paid off during the early 1950s.
A French sesquiplane built for breaking the Altitude World Record, Potez 506. This airplane was a version of the two seat multirole military biplane Potez 50, it was of conventional construction of welded steel tubes, wood, fabric and a nose covered with a thin metal sheet, but instead having the 700 hp Lorraine engine Potez 506 was motorize with a 800 hp Gnome-Rhone 14Kdrs Mistral Major 14-cylinder, double row radial engine, with a supercharger and a three blade propeller, also the wing sapn was increased in a 25%, and 100 kg of weigth were saved. Flown by Gustave Lemoine, it reached 44,820 ft on 28 September 1933, an altitude limited by icing of the pilot's eyes
as he sat in his open cockpit. He used oxygen but had no pressure suit.
A lesser known fighter of the era, the Romanian IAR-15. A lw wing monoplane with cantilever wing, and a mixed fuselage of welded steel tubes, covered with dural in the forward section and with fabric in the aft. Equiped with a 9-cylinder Gnome & Rhone radial, its performance was equal to most of the fighters of the era. With fixed wheels and open cockpit, it was a clear example of an aircraft of a transition period.
Finally, a 5 seat British touring biplane, the AVRO 641 Commodore, of conventional construction and motorized with a Lynx radial engine, it was a sound aircraft, but despite this, only 6 were built.
Cheers.
