SBU Corsair
From Wikipedia, the free encyclopedia
The Vought SBU-1 Corsair was a two seat, all metal biplane dive bomber built by Vought Aircraft Company of Dallas, Texas for the US Navy. Its design was based upon the F3U-1 two seat fighter that was abandoned when the Navy decided not to build any more two seat fighters. The aircraft was equipped with a closed cockpit, had fixed landing gear, and was powered by a Pratt & Whitney R-1535 radial air-cooled engine as had the F3U-1, but also included a controllable pitch propeller and a new NACA cowl with adjustable cowling gills on the trailing edge of the cowl. The adjustable cowling gills permitted better control of cooling airflow over the engine.
The SBU-1 completed flight tests in 1934 and went into production under a contract awarded in January 1935. The Corsair was the first aircraft of its type, a scout bomber, to fly faster than 200 mph.
