PZL.12
PZL.12 (PZL-H) was a prototype of a Polish amphibious flying boat designed and built in 1931 by Zygmunt Puławski, a pioneering Polish designer. He was killed in a crash involving this design. Design and development The Polish designer Zygmunt Puławski of the PZL works designed PZL-H in 1930, as a small touring amphibious aircraft, for his own needs. The factory agreed to construct a single aircraft for Puławski. At the same time, the Polish Navy revealed interest in training and liaison seaplanes, and PZL-H was proposed to the Navy. In late 1930 the prototype was built in the PZL in Warsaw in a semi-amateur way. It finally was given a designation PZL.12. The prototype was first flown in February 1931 in Warsaw by Puławski, in a land configuration (without auxiliary floats). The plane was not tested on water. During the sixth flight on 21 March 1931, right after take-off, the plane stalled due to strong wind and crashed in Warsaw, killing Puławski. The death of this talen ...

Zygmunt Puławski
Zygmunt Puławski (October 24, 1901 – March 21, 1931) was a Polish aircraft designer and pilot. He invented a gull-wing aircraft design, also known as "Puławski wing" and designed a series of Polish PZL fighters. He was born in Lublin. In the summer of 1920, during the Soviet offensive in the Polish-Soviet War, he volunteered for a Boy Scout battalion. In late 1920 he commenced studies at Warsaw University of Technology. He was a member of the Aviation Section of the Students' Mechanical Club, where he constructed some gliders. He distinguished himself as a thorough and able student. In 1925 he graduated from the University, receiving the Engineer title, and left for practice in the Breguet works in France. After his return, he served in the national service, completing military aviation school in Bydgoszcz and becoming a pilot. From 1927 he became a main designer of the Central Aviation Workshops (CWL) at Słupecka Street in Warsaw, soon reorganized into the PZL ('' ...

Państwowe Zakłady Lotnicze
PZL (''Państwowe Zakłady Lotnicze'' - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, and a brand of their aircraft. Based in Warsaw between 1928 and 1939, PZL introduced a variety of well-regarded aircraft, most notably the PZL P.11 fighter, the PZL.23 Karaś light bomber, and the PZL.37 Łoś medium bomber. In the post-war era, aerospace factories in Poland were initially run under the name WSK (Transport Equipment Manufacturing Plant), but returned to adopt PZL acronym in late 1950s. This was used as a common aircraft brand and later as a part of names of several Polish state-owned aerospace manufacturers referring to PZL traditions, and belonging to the ''Zjednoczenie Przemysłu Lotniczego i Silnikowego PZL'' - PZL Aircraft and Engine Industry Union. Among the better-known products during this period is the PZL TS-11 Iskra jet trainer and PZL-104 Wilga STOL utility aircraft. After the fall of communism in Poland in 1989, these man ...

Amphibious Aircraft
An amphibious aircraft or amphibian is an aircraft (typically fixed-wing) that can take off and land on both solid ground and water, though amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes ( flying boats and floatplanes) which are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared to planes designed specifically for land-only or water-only operation. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up. Design Floatplanes often have floats that are interchangeable with wheeled landing gear (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the DHC Otter, incorporate retractable wheels within their floats. Many amphibian aircraft are of the flying boat type. These aircraft, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Gipsy III
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre (300 cubic inch) capacity engine, later versions were designed to run inverted with increased capacity and power. The Gipsy went on to become one of the most popular sport aircraft engines of the inter-war period and was the engine of choice for various other light aircraft, trainers, liaison aircraft and air taxis, British as well as foreign, until long past World War II. Apart from helping to establish the de Havilland Aircraft Company as a manufacturer of light aircraft, it also established the company as an engine manufacturer in its own right. Gipsy engines remain in service powering vintage light aircraft. Design and development Just like the ADC Cirrus, the Gipsy was born as a collaboration between aircraft manufacturer Geoffre ...

Flying Boats
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s Polish Civil Utility 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. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor.

FBA 17
The FBA 17 was a training flying boat produced in France in the 1920s. Design and development Similar in general layout to the aircraft that FBA had produced during World War I, the Type 17 was a conventional two-bay biplane with unequal-span, unstaggered wings and side-by-side open cockpits. The pusher engine was mounted on struts in the interplane gap. Apart from their use by the French Navy, a small number were sold to the Polish Navy, the Brazilian Air Force, and civil operators as well. Some versions were built as amphibians, and others had fittings to allow them to be catapulted from warships. In 1931, the US Coast Guard purchased an example for evaluation, and being pleased with the design, arranged for the type to be built under licence by the Viking Flying Boat Company in New Haven, Connecticut. Six aircraft were eventually produced and served with the Coast Guard under the designation OO until the outbreak of World War II. Variants ;17 HE.2:(''Hydravion d'Écol ...

Nikol A-2
The Nikol A-2 was a small, amphibious aircraft designed and built in Poland in the 1930s. Only one was completed before World War II. Design and development The Nikol A-2 had a very long gestation time; its designer, Jerzy Nicol started work on it in May 1929, shortly after his graduation from Warsaw Technical University, but the first flight was made almost ten years later on 4 March 1939. In 1934 the Polish Navy, with an interest in a catapult-launched amphibian for a new warship, contacted Nikol. By the end of 1935 wind tunnel tests had been completed and design calculations approved. Construction of the prototype began in 1936 in the Morski Dyon Lotniczy factory at Puck. The all-wood, two-seat amphibian had a shoulder mounted cantilever wing built around two spars. Tapered in plan, the wing was plywood covered forward of the rear spar, forming watertight compartments to keep the aircraft afloat after severe hull damage. Behind the rear spar the wing was fabric cov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strut
A strut is a structural component commonly found in engineering, aeronautics, architecture and anatomy. Struts generally work by resisting longitudinal compression, but they may also serve in tension. Human anatomy Part of the functionality of the clavicle is to serve as a strut between the scapula and sternum, resisting forces that would otherwise bring the upper limb close to the thorax. Keeping the upper limb away from the thorax is vital for its range of motion. Complete lack of clavicles may be seen in cleidocranial dysostosis, and the abnormal proximity of the shoulders to the median plane exemplifies the clavicle's importance as a strut. Architecture and construction Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. Struts may be vertically plumb or leaning (then called canted, raking, or angled) and may be straight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
