Historie: Turbínový zemědělec - M15 BELGEFOR

Following an agreement between the Polish and Soviet governments for the design and production of a new large agricultural aircraft, allocated the designation P.Z.L. Mielec M-15, design of this aircraft was initiated in late 1971 and the initial LLP-M15 prototype made its first flight on 30 May 1973. One M-15 prototype and five pre-production aircraft followed, and completion of the development programme was signified by the award of a full certificate of airworthiness on 4 April 1979. Of unusual configuration, the M-15 had unequal-span biplane wings, twin tailbooms extending aft to twin fins and rudders united by a high-set tailplane and elevator, and fixed tricycle landing gear. A central fuselage nacelle provided accommodation for the pilot and, to his rear, had a cabin to seat two ground crew during ferry flights between operating areas. The single turbofan power-plant was mounted above the fuselage nacelle, and two streamlined chemical hoppers occupied the full gap between each wing, mounted directly beneath the tailbooms, their combined chemical capacity 2900 litres.

Plans had been made to manufacture 3,000 M-15s, which had been given the name Belphegor during 1979, but production ended in 1981 after only 120 had been built because the aircraft was uneconomical in operation, P.Z.L. producing the turboprop An-3 instead.
