The Oškinis BRO-16, sometimes known as the Oškinis BRO-16 Pempė (Pempė in Lithuanian translates as Northern Lapwing), was a flying boat, biplane training glider, flown and produced in the USSR in the 1970s.
The BRO-16 was a single-seat training glider, unusual for being both a biplane and a flying boat. It was a development of the BRO-11 land monoplane produced some twenty years earlier and first flew in August 1973.[1]
Its wings were rectangular in plan out to rounded tips. The lower wing was 25% shorter in span than the upper but with about the same chord and ply-covered in contrast to the fabric covered upper wing. Both wings had single-spar structures and were braced together with wide spread, transverse, streamlined and distorted V-struts between the spars. There was no stagger, 3° of dihedral and a large interplane gap. The BRO-16's push-rod activated, fabric-covered ailerons, which could also serve as flaps, were suspended from the upper wing and filled 87% of the span.[1]
The BRO-19's fuselage had a forward nacelle attached to a flat girder fuselage supporting the tail. The largely wooden nacelle was 3.70 m (12 ft 2 in) long and flat-bottomed. The cockpit, close to the nose, was open and placed the pilot over the leading edge of the lower wing which was mounted on the side of the nacelle, about halfway back. The rear of the fuselage was formed by a horizontal girder member, just under the upper wing, attached to the nacelle with a pair of vertical struts between the wings and an oblique strut from the rear of the nacelle to the top of the aft vertical strut. Wires braced the rear fuselage to the wing struts and to the nacelle. Parts of the girder were canvas-covered.[1]
The tail was conventional. Though the triangular fin was very small, the rudder was large, nearly rectangular in profile apart from a blunted top and a slightly angled underside. The tailplane was triangular in plan and carried rectangular elevators. All the tail surfaces were fabric-covered wooden structures.[1]
Operational historyedit
The BRO-16 was mass produced, though numbers are not available. They operated from the Lithuanian Kaunas Reservoir.[2]
