The Blaicher B.1 was a Polish glider first flown in 1934. It was intended to fill an intermediate trainer role, but offered no advance on existing aircraft and only the prototype was completed.

Design and development

In about 1932 the Institute of Gliding Technique (I.T.S.) released a specification for an intermediate glider which resulted in the ITS-II. Michal Blaicher was a glider pioneer in Poland who later was in charge of the Military Gliding Camp (W.O.S.) at Ustianowa. His 1933 design was aimed at the same intermediate class but intended to have better performance than the 1933 Kocjan Komar, which had displaced the ITS-II. It was built in the Lwów workshops of ZASPL, the Aviation Association of students of the Technical University and the oldest aviation organization in Poland, which had also built the ITS-II. The Blaicher B.1's first flight was on 29 March 1934, piloted by its designer. [1] Tests at Ustianowa, flown by Edward Peterek, showed no significant improvement over the Komar so no production resulted, though the sole prototype remained operational for two more years. [1] [2]

The Blaicher B.1 had a two-part, twin spar wing of rectangular plan out to angular tips. It was plywood-covered from the forward spar around the leading edge, forming a D-box. Behind, the wing was fabric covered. It was mounted centrally on a raised, streamlined pedestal which extended aft of the wing, dropping in height, to the tail. Two pairs of parallel struts braced the wing to the lower fuselage. The pilot's open cockpit was immediately ahead of the pedestal and wing leading edge. [1] [2]

The fuselage was hexagonal in section, though dominated by deep, vertical sides and covered with ply forward and fabric aft. A sprung landing skid ran from the nose almost to the trailing edge, aided by a short tailskid. At the rear a triangular tailplane, mounted on top of the fuselage and braced from below with a single strut on each side, carried straight-edged, round tipped elevators with a central cut-out for rudder movement. The fin was very small but mounted a full, rounded and balanced rudder. [1] [2]

The ITS-8 was a Polish twin-boom motor glider flown in 1936. Two prototypes were completed but production was prevented by the German invasion of Poland in 1939.

The Czerwiński CW 5bis was a Polish high performance sailplane, produced and developed between 1933 and 1935. It set several national records, competed at both national and international level and remained a Polish gliding club mainstay until the outbreak of World War II.

The ITS-II was a Polish intermediate training glider. Only about five were built as it was soon outclassed by newer Polish aircraft but some were used until 1935. ITS-IIs were used in early training courses on air towing and another gave the first demonstration of glider aerobatics in Poland. It was also used to set one national record.

<span class="mw-page-title-main">Czerwiński CW 7</span> Type of aircraft

The Czerwiński CW 7 was a Polish aerobatic glider first flown in 1934. Despite a structural weakness that prevented inverted flight, a small batch of CW 7s were used by several aeroclubs until the start of World War II.

<span class="mw-page-title-main">Czerwiński CW 8</span> Type of aircraft

The Czerwiński CW 8 was a mid-1930s Polish open-frame basic training glider. Its design was advanced and its price low, but its stalling characteristics were too dangerous for beginners, so the thirty-plus examples completed were rapidly withdrawn from use. Two were subsequently modified, one with greater span and the other with a small engine.

The Czajka (transl. Lapwing) or Kocjan Czajka after its designer was a Polish secondary training glider which was in continuous production from 1931 to the start of World War II. More than 160 were completed in Warsztaty Szybowcowe in Warsaw.

<span class="mw-page-title-main">Warsztaty Szybowcowe Sroka</span> Type of aircraft

The Warsztaty Szybowcowe Sroka, or Kocjan Sroka after its designer, was a Polish intermediate training glider. About sixty were built between 1934 and 1939.

The Rubik R-03 Szittya I was a Hungarian single-seat sailplane flown in the late 1930s. The design was developed through three improving variants. though only one of each was built.

<span class="mw-page-title-main">Rubik R-07 Vöcsök</span> Type of aircraft

The Rubik R-07a Tücsök (Cicada) and R-07b Vöcsök (Grebe) were two versions of a Hungarian primary trainer, differing most obviously in the pilot's seating. First flown in the late 1930s, about 530 were built, some remaining in service into the 1960s.

<span class="mw-page-title-main">Rubik R-15 Koma</span> Hungarian training glider

The Rubik R-15 Koma (Godfather) was a side-by-side seat Hungarian training glider designed to introduce pilots to winch-launching techniques. A second, very similar but single seat design, the Rubik R-16 Lepke, provided follow-up solo experience of the same techniques. Pairs were widely used by Hungarian glider clubs post-war, with 65 of each produced.

The Rubik R-17 Móka (Joy) was a Hungarian aerobatic glider designed in the late 1930s. One prototype was built and first flown in 1944 but was destroyed near the end of World War II. Two more, with modified ailerons and a new fuselage, were built in 1950 but were abandoned after a fatal accident.

The MSRz Bene was a Hungarian two seat primary glider, first flown in 1952. By this time its competitor had been awarded a serial production order, so only one working Bene was ever completed.

<span class="mw-page-title-main">Kocjan Komar</span> Type of aircraft

The single-seat Kocjan Komar (Gnat) intermediate trainer, designed in 1932, was the leading and most produced sailplane in pre-war Poland. Production was resumed after World War II as the IS-B Komar and it remained in use until 1965.

The PZL M-3 Pliszka (Wagtail) was the first all-metal Polish glider. Three were built but its performance, particularly its glide ratio, was not good enough for it to be produced for Polish clubs.
