PZL.26
PZL.26 was a Polish sports plane built in 1934 in the PZL works. Ordered by the Ministry of Defence, it was specifically designed for the upcoming Challenge 1934 International Touring Aircraft Contest. Design and development The PZL.26 was a development of the PZL.19, that was built for previous Challenge 1932 contest. Like its predecessor, it was designed by Jerzy Dąbrowski and Franciszek Misztal in 1933. The plane was an all-metal cantilever low-wing monoplane with a fixed landing gear and a closed canopy. It retained wings and tail of the PZL.19, with minor changes. A fuselage, wings and landing gear were more streamlined and strengthened. The main change was a stronger engine, a US-made 265 hp Menasco Buccaneer B-6S3 engine. The engine choice appeared to be a failure, though. Five aircraft were built in 1934 and one prototype for static trials. They carried registration markings: SP-PZL to PZP. Operational history All five PZL.26s took part in the Challenge from August ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Challenge 1934
The Challenge 1934 was the fourth and last FAI International Tourist Plane Contest (french: Challenge International de Tourisme), that took place between August 28 and September 16, 1934, in Warsaw, Poland. The four Challenges, from 1929 to 1934, were major aviation events in pre-war Europe. The 1934 Challenge was won by the Polish pilots, who had also won the previous year. Overview Poland and the Polish Aero Club organized the contest because a Polish pilot Franciszek Żwirko had won the previous Challenge in 1932. The contest rules were announced in June 1933: like the previous contest, it consisted of three parts: technical trials, a rally over Europe and a maximum speed trial, but there were changes in details. Since one of the aims of the Challenges was to stimulate the development of tourist aircraft, a stress was placed upon aircraft performance and quality, although pilots' skills remained crucial. The opening ceremony was held at noon on August 28, 1934, at Mokotow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klemm Kl 36
The Klemm Kl 36 is a 1930s German four-seat cabin touring and competition monoplane. It was designed by Klemm and Friedrich Fechner and built by Klemm. History Development Following the success of the 3-seat touring plane Klemm Kl 32 in the European touring plane championship Challenge 1932, the company was ordered by the German Reichs luftfahrt ministerium (RLM) to develop another aircraft to take part in Challenge 1934. Due to changes in contest rules, it had to be a more modern machine, a 4-seater, featuring better performance and better STOL capabilities. As a result, the Kl 36 was a streamlined, comfortable four-seat plane with wing mechanization. It was the fastest of all Klemm's builds. Four aircraft were builtAccording to Krzyżan, M. - 5 aircraft, along with a prototype of the Kl 36A series (two powered by Argus As 17inverted 6-cylinder in-line engines, and two by Hirth HM8U inverted V8 engines - D-IHEK, D-IHAV. Both engines were air-cooled). Later, 8 0-series airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fieseler Fi 97
The Fieseler Fi 97 was a 1930s German four-seat cabin touring and competition monoplane aircraft designed and built by the German manufacturer Fieseler. Design and development Following the success of their two-seat tourer/trainer the Fieseler F5, Fieseler was encouraged by the German Reichsluftfahrtministerium (RLM) to develop a four-seat version specially to take part in the European touring plane championship Challenge 1934. The result of this request was the Fi 97, designed by Kurt Arnolt. It was a mixed-construction low-wing cantilever monoplane with a conventional tail unit. The fuselage had a fabric-covered steel tubing frame. The wing structure was wood and was covered with fabric and plywood. The wings were able to be folded aft for storage or ground transport. The tailskid undercarriage was fixed. The pilot and three passengers had an enclosed cabin. Five examples of the Fi 97 were built. Three aircraft were fitted with the Hirth HM 8U, 250 hp inverted V8 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polish Aero Club
Aeroklub Polski (AP; ''Polish Aero Club'') is the Polish central association of persons practising air sports or recreational flying. It was founded in 1921 and is a member of the Fédération Aéronautique Internationale. It has a headquarters in Warsaw. History Aviation organizations could be founded in Poland only after regaining independence in 1918. The first such organization was Aeroklub Polski w Poznaniu (''PAC in Poznań''), founded on 30 October 1919 and admitted to the FAI in 1920. In June 1920 there was founded Aeroklub Polski w Warszawie (''PAC in Warsaw''). On 18 January 1921 both Aero Clubs formed a central federation Aeroklub Rzeczypospolitej Polskiej (ARP; ''Aero Club of the Polish Republic''). By 1939, there were created several other regional aero clubs, including some university aero clubs. Before the World War II, members of the ARP took active part in world's aviation sports. The first major international event was the Challenge 1930 touring planes contes ... [...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 ...

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] |
Menasco Buccaneer B-6S
The Menasco Motors Company was an American aircraft engine and component manufacturer. History The company was organized by Albert S. Menasco in 1926 to convert World War I surplus Salmson Z-9 water-cooled nine-cylinder radials into air-cooled engines for private use. His association with John K. (Jack) Northrop and his flying wing project in the late 1920s convinced him of the need for a new configuration of aircraft engine: an inverted in-line air-cooled layout that would have the propeller shaft on top for better ground clearance and improved pilot vision. In 1929, Menasco designed his own engine, the 4-A, the first of what was to become Menasco's main product line, the inverted, in-line engine. Menasco designed and built a variety of four- and six-cylinder inverted air-cooled aircraft engines, some with supercharging. During WWII, Menasco manufactured aircraft landing gear for North American, Lockheed, Republic, General Dynamics, and others. After WWII, aircraft landin ...
