The SAB-SEMA 10 was a single engine advanced trainer, designed and built in France as the SEMA 10, in the 1930s. It failed to win a French production contract and only one was built. Re-engined, modified and redesignated SAB-SEMA 10, it served with the Spanish Republican Air Force at the beginning of the Spanish Civil War.
Design and development[]
The SAB-SEMA 10 was designed by La Societé d'Etudes de Materiel d'Aviation and built by La Sté Aérienne Bordelaise to compete for a 1933 French government contract for an intermediate and advanced military trainer. It was a conventional biplane, metal framed and fabric covered and powered by a 240 hp (180 kW) Lorraine 7Mc Mizar 7-cylinder radial engine. Instructor and pupil occupied open tandem cockpits.[1]
The SAB-SEMA 10 failed to gain a production contract when the competition was won by the Romano R.82. It was then re-engined with a more powerful 300 hp (224 kW) Lorraine 9Na Algol 9-cylinder radial with a Townend ring cowling. At the same time wing and tail modifications were made and the aircraft redesignated as the SAB-SEMA 12. This was a single bay biplane with N-form interplane struts. The lower wing had a smaller chord than the upper one but both carried ailerons, externally connected. The fuselage was flat sided and the tailplane was mounted on top of it. The fin was tall and the rudder extended to he bottom of the fuselage, moving between separate elevators. It had a conventional undercarriage with mainwheels in spats.[1]
Operational history[]
In October 1936 the SAB-SEMA 12 was sold to the Republican forces for use as a trainer in the Spanish Civil War. It was based at the Los Alcázares flying school in Murcia.[1]
