Design and development

The DAR-10 was designed by Zvetan Lazarov in 1938 in the DAR (Darzhavna Aeroplanna Rabotilnica, meaning literally 'State Airplane Workshop') factory in Bozhurishte, near the capital Sofia. Bozhurishte (Божурище is a town in western Bulgaria. It is located in Sofia Province and is close to Kostinbrod and the capital Sofia (София ˈsɔfija is the Capital and largest city of the Republic of Bulgaria, with a population of 1395568 in the Capital Municipality

The Dar-10 was a single-engine two-seat (pilot and gunner) low-wing cantilever monoplane aircraft of conventional layout. A cantilever is a beam supported on only one end The beam carries the load to the support where it is resisted by moment and Shear stress. Its two seats were in tandem under enclosed glazing. Its tailwheel undercarriage was fixed, and the main gears were spatted. Conventional landing gear describes an Undercarriage arrangement consisting of two main weight-bearing wheels forward of the aircraft's Centre of gravity, the A fairing is a structure whose primary function is to produce a smooth outline and reduce drag. the wings had wooden structure, covered with plywood. Plywood is a type of Engineered board made from thin sheets of Wood, called plies or veneers Flaps were not used. Flaps are hinged surfaces on the trailing edge of the wings of a Fixed-wing aircraft.

The fuselage was comparatively wide and deep, to accommodate the nose-mounted radial engine. The fuselage (from the French fuselé "spindle-shaped" is an Aircraft 's main body section that holds crew and passengers or Cargo The radial engine is a reciprocating type internal combustion Engine configuration in which the cylinders point outward from a central 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: "snipe"), powered by an Alfa Romeo 128 R.C.21 9-cylinder radial engine rated at 950 hp (709 kW). Bulgarian (български език IPA: ɛzˈik is an Indo-European language, a member of the Slavic linguistic group A snipe is any of nearly 20 wading bird species in three genera in the family Scolopacidae. Alfa Romeo built/designed several aircraft engines based on Bristol Jupiter and Pegasus designs This was the first DAR-10 to fly, in July 1941. This is a list of Aviation -related events from 1941: Events Jackie Cochran became the first woman to fly a bomber across the It was designed to carry four machine guns (2 fixed forward-firing and 2 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 the summer of 1942. In spite of good flight reviews, the type was not chosen for production. The high-wing 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 rated at 870 hp (649 kW). The Fiat A74 was a two-row fourteen-cylinder air-cooled radial engine product in Italy in the 1930s as a powerplant for aircraft 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 flaps, it could serve also as a dive bomber. A dive bomber is a Bomber aircraft that Dives directly at its targets in order to provide greater accuracy and limit the exposure to and effectiveness of It could be equipped with two fixed fuselage-mounted 20 mm cannons firing forward, two fixed wing-mounted machine guns, and two machine guns for the gunner. It could carry 650 kg bombs (1 x 250 kg and 4 x 100 kg) - or 450 kg, according to other data. The bombs would be mounted under the 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 Stuka dive bomber. The Junkers Ju 87 or Stuka (from Stu rz' ka' mpfflugzeug, " Dive bomber " was a two-seat (pilot and rear gunner
