The Romano R.90 is a French fighter aircraft of the 1930s. It only existed as a prototype .
development
The R.90 was created due to the French navy's request for a ship-based , catapultable fighter aircraft as a rival design to the Bernard H.110 , Loire 210 and Potez 453 . The prototype initially received a nine-cylinder radial engine from Hispano-Suiza and made its maiden flight in August 1935. The drive power was probably unsatisfactory, because in October it was converted to a more powerful 14-cylinder engine from the same manufacturer. Finally, according to official instructions, a V-engine Hispano-Suiza 12 Ycrs was used, with which the model was tested in 1936 and referred to as R.92 in contemporary publications, but that too did not result in a production order. Instead, the Loire 210 went into a limited series. Another airplane with a wheeled landing gear is said to have been developed in 1938 by a Belgian company for Republican Spain under the abbreviation R.92 and built as a prototype.
construction
The R.90 is a single-legged, braced and staggered double-decker with a floating mechanism in a mixed construction . The fuselage is a framework construction made of welded steel tube with an oval cross-section, which is planked with sheet metal in the front part and covered with fabric in the remaining area. The supporting structure is made up of the two-part upper and lower wings of the same span, consisting of fabric-covered wooden frames and connected to one another by N-posts. They are located on short stumps that merge into the trunk and can be folded back onto the trunk. The upper wings are designed as a gull wing . All four surfaces are equipped with ailerons and connected to one another by bumpers. The tail unit in normal configuration has an horizontal fin that is braced towards the fuselage and fin. The wooden floats have one step and are reinforced for use with a catapult.
