DAR-10 was designed for horizontal and dive bombing, reconnaissance, and ground attack. ==Design and development== The DAR 10 was designed by Zvetan Lazarov in 1938 in the DAR (''[Darzhavna Aeroplanna Rabotilnitsa](/source/Darzhavna_Aeroplanna_Rabotilnitsa)'', meaning literally 'State Airplane Workshop') factory in [Bozhurishte](/source/Bozhurishte), near the capital [Sofia](/source/Sofia). The DAR 10 was a single-engine two-seat (pilot and gunner) low-wing [cantilever](/source/cantilever) monoplane aircraft of conventional layout. Its two seats were in tandem under enclosed glazing. Its [tailwheel undercarriage](/source/Conventional_landing_gear) was fixed, and the mainwheels were [spatted](/source/Aircraft_fairing). The wings had a wooden structure, covered with [plywood](/source/plywood). [Flaps](/source/Flap_(aircraft)) were not used. The [fuselage](/source/fuselage) was comparatively wide and deep, to accommodate the nose-mounted [radial engine](/source/radial_engine). It was constructed of steel-tube framework and wood formers, covered with fabric. Three-bladed steel propellers were used. Two prototypes were built, powered by different engines: *'''DAR 10A ''Bekas''''' ([Bulgarian](/source/Bulgarian_language): "[snipe](/source/snipe)"), powered by an [Alfa Romeo 128 R.C.21 nine-cylinder radial engine](/source/Alfa_Romeo_125) rated at 950 hp (709 kW). This was the first DAR 10 to fly, on 2 July 1941.Bernád 2001, p.29. It was designed to carry four machine guns (two fixed forward-firing and two in rear gunner position). It could carry five 100-kg bombs, mounted under the wings. There was also the possibility of a fixed 20 mm forward-firing cannon installation in the forward fuselage. This aircraft crashed in October 1942. In spite of good flight reviews, the type was not chosen for production. The high-wing [KB-11 Fazan](/source/KB-11_Fazan) was selected for production instead. *'''DAR 10F''' (the "F" to indicate its Fiat engine), powered by a [Fiat A 74 R.C.38 14-cylinder radial engine](/source/Fiat_A.74) rated at 870 hp (649 kW). This aircraft first flew in March 1945. It was slightly heavier and longer than the DAR-10A. Its top speed was 454 km/h (282 mph). Thanks to a stronger construction and dive brakes, it could serve also as a [dive bomber](/source/dive_bomber). It could be equipped with two fixed fuselage-mounted 20 mm cannon firing forward, two fixed wing-mounted machine guns, and two machine guns for the gunner. It could carry one 500 kg (1,100 lb) bomb or one 250 kg (551 lb) and four 100 kg (110 lb). The bombs were mounted under the fuselage and wings. The DAR-10 was not selected for production. Some sources suggest that it was passed over in favor of the German [Junkers Ju 87](/source/Junkers_Ju_87) Stuka dive bomber, while the improved DAR-10F was not selected as [World War II](/source/World_War_II) had ended and Bulgaria had access to ample supplies of modern Soviet aircraft such as the [Ilyushin Il-2](/source/Ilyushin_Il-2) and [Il-10](/source/Ilyushin_Il-2). ==Variants== ;DAR-10A :First prototype, powered by an Alfa Romeo radial engine. ;DAR-10F :Second prototype, powered by a Fiat radial engine. ==Operators== ;{{flag|Bulgaria|1878}} *[Bulgarian Air Force](/source/Bulgarian_Air_Force) ==Specifications (DAR-10)== {{aircraft specifications/switch |plane or copter?=plane |jet or prop?=prop |ref=Jane's Aircraft Recognition Guide{{cite book|title=Jane's Aircraft Recognition Guide|last=Rendall|first=David|page=[https://archive.org/details/janesaircraftrec0000rend/page/505 505]|year=1995|isbn=0-00-470980-2|publisher=HarperCollinsPublishers|location=Glasgow, UK|url-access=registration|url=https://archive.org/details/janesaircraftrec0000rend/page/505}} |crew=two |length main=9.54 m |length alt=31.3 feet |span main=12.20 m |span alt=40.0 feet |height main=3.3 m |height alt=10.8 feet |area main=22.2 m² |area alt=239 ft² |empty weight main=1,843 kg |empty weight alt=4,063 lb |loaded weight main=2,570 kg |loaded weight alt=5,666 lb |useful load main= |useful load alt= |max takeoff weight main= |max takeoff weight alt= |engine (prop)=[Alfa Romeo 128 R.C.21](/source/Alfa_Romeo_125) |type of prop= |number of props=1 |power main=708 kW |power alt=950 hp |max speed main=410 km/h |max speed alt=255 mph |max speed more= |never exceed speed main= |never exceed speed alt= |range main=1,170 km |range alt=727 miles |ceiling main=7,250 m |ceiling alt=23,785 feet |climb rate main= |climb rate alt= |loading main= |loading alt= |thrust/weight= |armament=
