PWS-8
The P.W.S.8 was a 1930 Polish sports plane, constructed by the '' Podlaska Wytwórnia Samolotów'' (PWS), that remained a prototype. Design and development The plane was designed in 1929 by Jarosław Naleszkiewicz in ''Podlaska Wytwórnia Samolotów'', on factory's initiative, to participate in the Challenge 1930 international touring aircraft contest (with P.W.S.50, P.W.S.51 and P.W.S.52). It was a wooden biplane, partly modelled after de Havilland Gipsy Moth.Glass, A. (1977), p.184-185 Its unique feature, taken from earlier PWS military aircraft, like P.W.S.5, were N-shaped struts between lower and upper wing and additional oblique transverse struts, stiffening the design, instead of wire braces (similar bracing to Handley Page Gugnunc). The plane was first flown in 1929 or 1930 by F. Rutkowski, with Armstrong Siddeley Genet 80 hp radial engine. In spring of 1930 it was modified, with Walter Vega 85 hp radial engine, also a tailfin shape and some other details we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Challenge 1930
The International Touring Competition in 1930 (french: Challenge International de Tourisme) was the second FAI international touring aircraft contest, that took place between July 18 and August 8, 1930 in Berlin, Germany. Four Challenges, from 1929 to 1934, were major aviation events in pre-war Europe. Overview Germany organized the contest, because the German pilot Fritz Morzik won the previous contest in 1929. The regulation based upon the FAI rules, but details were worked out by the German Aero Club. The international Sports Committee was headed by the German Gerd von Hoeppner. 98 crews applied, but eventually 60 aircraft entered the Challenge in 1930, from six countries: Germany (30 crews), Poland (12 crews), United Kingdom (7 crews), France (6 crews), Spain (3 crews) and the Swiss (2 crews). In the British team there was one Canadian, and in the French team – one Belgian. It was the first major international event in which the Polish aviation took part, with second most nu ...

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 pass ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

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.

Simmonds Spartan
The Simmonds Spartan is a 1920s British two-seat biplane trainer/tourer aircraft built by Simmonds Aircraft Limited. History Not happy with the high cost of manufacturing light aircraft, O.E. Simmonds designed and built a wooden two-seat biplane in 1928. To reduce maintenance costs all four wings and ailerons were the same; this allowed one spare wing to be used in any position. Powered by a Cirrus III, the prototype G-EBYU first flew in time to enter the King's Cup Air Race of 1928. The aircraft was flown to the Berlin Aero Show on 24 October 1928, a non-stop flight of 7 hours and 10 minutes. Production began at Woolston, Hampshire, with the final assembly and test flying at Hamble Aerodrome. Forty-nine aircraft were built, many for export, with New Zealand customers buying the most. At home 12 were delivered to the National Flying Services for use as trainers. Three aircraft were operated on floats in Fiji. Although not as famous as other aircraft of the period, one aircraft ...

Avro Avian
The Avro Avian was a series of British light aircraft designed and built by Avro in the 1920s and 1930s. While the various versions of the Avian were sound aircraft, they were comprehensively outsold by the de Havilland Moth and its descendants. Design and development The Avro 581 Avian prototype was designed and built to compete in the Lympne light aircraft trials at Lympne Aerodrome in September 1926. Its wooden fuselage was based on that of the Avro 576 autogyro, but it was fitted with conventional biplane wings and powered by a 70 hp (50 kW) Armstrong Siddeley Genet engine. It performed well at the trials, but was eliminated due to engine failure. In early 1927 it was re-engined with an ADC Cirrus engine as the Type 581A and sold to Bert Hinkler. Production aircraft were designated Type 594 and were built in a number of versions, mainly powered by Cirrus engines.Jackson 1990, pp. 249, 256. A version with a welded steel tube fuselage was produced in 1929 as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...
