PWS-35
The PWS-35 ''Ogar'' ( en, Polish Hound) was a two-seat, aerobatic training biplane that was designed by Kazimierz Nowicki, Marian Piątka and Michał Rosnowski at the Lviv Polytechnic in 1935/1936. Design and development The aircraft was designed by three young scientists at the Lvov University of Technology ("Polytechnic") as their thesis. The designers initially planned to build a single aircraft (designated as the NPR-1, after the initials of the design team's members), but in 1937 the Podlaska Wytwórnia Samolotów became interested in their design and hired professional designers to modify it to fit the needs of the Polish Air Force. At the time the PAF was looking for an advanced trainer and it was decided that Ogar would be perfect for that role. The prototype was completed in 1937 and in early 1938 underwent static tests. In the summer of 1938 it was successfully test-flown by S. Szubka. The first prototype, equipped with a de Havilland Gipsy Major engine, was heavier t ...

Podlaska Wytwórnia Samolotów
Podlaska Wytwórnia Samolotów (PWS) - ''Podlasie Aircraft Factory'' - was a Polish aerospace manufacturer between 1923 and 1939, located in Biała Podlaska. History Podlaska Wytwórnia Samolotów SA was created in 1923. The first aircraft produced were 35 Potez 15 bombers for the Polish Air Force, under the French licence, built from 1925.Glass, A. (1977), p.22-25 By 1929 the works had produced 155 Potez 27 and 150 Potez 25, under French licence, and 50 PWS-A fighters, which was the Czech Avia BH-33 built under licence. It also produced 50 Bartel BM-4 trainers in 1931, designed by Samolot. In 1925, a design office was established which included, among others, Stefan Cywiński, Zbysław Ciołkosz, August Bobek-Zdaniewski. Despite a large number of prototypes, few were produced in series. The first aircraft of their own design to be mass-produced was the PWS-10 fighter of 1930 of which 80 examples were built. Smaller production runs of the PWS-14 trainer and the PWS-24 ...

Aerobatic Aircraft
An aerobatic aircraft is an aerodyne (a heavier-than-air aircraft) used in aerobatics, both for flight exhibitions and aerobatic competitions. Most fall into one of two categories, aircraft used for training and by flight demonstration teams, which are often standard trainers or fighters, and aircraft especially designed for aerobatics, usually at the expense of other attributes, such as stability, carrying passengers or endurance. Dates are of first flight.

Stall (flight)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller t ...

1930s Polish Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Invasion Of Poland
The invasion of Poland (1 September – 6 October 1939) was a joint attack on the Republic of Poland by Nazi Germany and the Soviet Union which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty.

De Havilland Gipsy Major
The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types. Engines were produced by de Havilland in the UK and by the Australian arm of the company, de Havilland Australia, the latter modifying the design to use imperial measures rather than the original metric measurements. Design and development The engine was a slightly modified Gipsy III, which was effectively a de Havilland Gipsy engine modified to run inverted so that the cylinders pointed downwards below the crankcase. The Major was also bored-out (118 mm from 114 mm) compared to the Gipsy III, increasing displacement from 5 L to 6.1 L. The inverted configuration allowed the propeller shaft to be kept in a high position without having the cylinders blocking the pilot's forward view over the nose of the aircr ...
