The PIK-5 was a training glider produced in Finland in the 1940s, and 1950s, [1] equipping the country's gliding clubs with an aircraft greater in performance than primary gliders but less than competition sailplanes. [2]

Contents

The PIK-5 had a pod-and-boom configuration, with a high, strut-braced monoplane wing and a cruciform tail carried at the end of a tail boom that extended from a position high on the aft end of the pod. [3]

History

The prototype first flew in September 1946, [4] and testing continued until it was badly damaged in a crash in summer 1948 [5] Over the subsequent months, the wings were repaired, and a new fuselage constructed to a revised design. This was completed the following winter, and flights recommenced. [5] However, this aircraft, now known as the PIK-5B, was destroyed in a crash in summer 1951. [5]

Again, it was rebuilt with modifications, particularly to the wing structure, resulting in the PIK-5C version. [5] This version first flew on 5 July 1952, [5] and went on to become the pattern for around 30 similar machines that would be built over the ensuing years. [4]

The Fauvel AV.36 was a single-seat tailless glider designed in France in the 1950s by Charles Fauvel. Although the "AV" in AV.36 stands for Aile Volante, it was not a true flying wing: it featured two large fins mounted on stubby tailbooms extending back from the wing's trailing edge, and accommodated the pilot within a stubby fuselage. The aircraft was designed to be quickly disassembled for road transport, with the nose detaching, and the fins able to fold back against the trailing edge of the wing. A refined version with a slightly longer wingspan, the AV.361 was introduced in 1960.

The Fauvel AV.45 was an unorthodox motor glider produced in France in the 1960s and 1970s. Like other Charles Fauvel designs, it was a tailless aircraft, in this case inspired by the work that German firms had done on producing motorised versions of his AV.36 design. The prototype of the AV.45 was an extensively modified AV.36 powered by a Nelson H-59 two-stroke engine. AV.45s have been built with a number of other engines, however, including at least one aircraft powered by a small turbojet. Falconar marketed the plans in the 1970s.

The PIK-3 was a sailplane produced in Finland in the 1950s and 60s. It was designed to be a cheap and easy-to-build aircraft to equip the country's gliding clubs as their standard single-seat machine. It was a conventional design for its day, with a high wing and conventional empennage. Construction was of wood throughout, skinned in plywood.
