RWD 4
The RWD 4 was a Polish sports plane of 1930, constructed by the RWD team. Development The RWD 4 was constructed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki in Warsaw. It was based upon their earlier RWD 2 design, but enlarged and fitted with more powerful inline engine. It retained the same fish-shaped fuselage without a direct view forward from the pilot's seat, though the view improved due to thin fuselage profile before the pilot. Also a silhouette became slimmer. The aircraft development was ordered by the Ministry of Communication especially for participation in the Challenge 1930 international air competition. At the same time, the RWD developed similar liaison aircraft project, the RWD 3, which shared many features with the RWD 4. The first three aircraft (registration SP-ADK, -ADL and -ADM) were completed and flown by the designer Jerzy Drzewiecki in early 1930. In late 1930, a further six aircraft were built for the Polish Aero Club ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

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. 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. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace.

RWD 7
The RWD 7 was a Polish sports plane of 1931, constructed by the RWD team. Development The RWD 7 was constructed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki in Warsaw. It was based upon their earlier designs, especially the RWD 2 and RWD 4. The RWD 7 was meant to be a record-beating plane, so it had a more powerful engine, while its mass was reduced. From its predecessors, it took the same fish-shaped fuselage without a direct view towards forward from the pilot's seat. The only RWD 7 built (registration SP-AGH) was flown in July 1931 by its designer Jerzy Drzewiecki. On August 12, 1931, Drzewiecki and Jerzy Wędrychowski established an international FAI speed record of 178 km/h (111 mph) in the light touring plane class, (below 280 kg / 616 lb empty weight). On September 30, 1932, Drzewiecki and Antoni Kocjan set a height record of 6,023 m (19,755 ft). The RWD 7 was used in Warsaw Aero Club, among others, for aer ...

RWD 5
The RWD 5 was a Polish touring and sports plane of 1931, a two-seat high-wing monoplane, constructed by the RWD team. It was made famous by its transatlantic flight, being the smallest aircraft to cross the Atlantic. Development The RWD 5 was constructed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki (their designs were named RWD after their initial letters). It was a further development of earlier RWD aircraft series (RWD 1, RWD 2, RWD 3 and RWD 7), especially of its direct predecessor, the RWD 4. It shared the same wing shape and construction, while the fuselage was totally new, constructed of steel frame, unlike its wooden predecessors. The fuselage had a modern shape and a closed canopy with panoramic windows (earlier models had atypical fish-shaped fuselages with no direct forward view from the pilot's seat). The first prototype (registration SP-AGJ) was flown on 7 August 1931 by its designer Jerzy Drzewiecki. It was built in new workshops ...

RWD 1
The RWD 1 was a Polish sports plane of 1928, a single-engine high-wing monoplane constructed by the RWD design team. Development The RWD 1 was the first aircraft constructed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki in the Aviation Section of Mechanic Students' Club of Warsaw University of Technology. It was designed in late 1927. The plane was built with a financial help of the LOPP organization. One prototype was built for static trials, and one flying prototype (registration SP-ACC), completed and flown by the designer Jerzy Drzewiecki in September 1928. Its unusual feature was a unique, fish-shaped fuselage, similar to early Messerschmitt's designs ( M17). Two crewmen sat in tandem inside the fuselage and had only side openings in its upper part. In front of the pilot's head there was an upper part of the fuselage, supporting wings, limiting his view forward, though its profile was thin. This shape was repeated in following RWD designs. ...

Cirrus Hermes II
The ADC Cirrus is a series of British aero engines manufactured using surplus Renault parts by the Aircraft Disposal Company (ADC) in the 1920s. The engines were air-cooled, four-cylinder inline types. They were widely used for private and light aircraft. Design and development The Cirrus engine originated in Geoffrey de Havilland's 1924 quest for a powerplant suited to a light two-seat sports biplane which would become the de Havilland Moth. No suitable engine existed at the time, with both an appropriate level of power and light weight. The Aircraft Disposal Company, also known as Airdisco and ADC, were producing the low-cost Airdisco V8 which had been developed by Frank Halford from their large stocks of war surplus Renault V8 aero engines. De Havilland realised that half of this engine would make an air-cooled four-cylinder inline engine of just the right size and at low cost. He persuaded Halford to undertake its design and development. The cylinders, pistons, con-rods a ... [...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 ...

De Havilland Gipsy
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 ...

Cirrus Engine
The Cirrus and Hermes or Cirrus-Hermes are a series of British aero engines manufactured, under various changes of ownership, from the 1920s until the 1950s. The engines were all air-cooled, four-cylinder inline types, with earlier ones upright and later designs inverted. The first Cirrus design was created for the planned de Havilland Moth light aeroplane and, when it appeared in 1925, created the market for private flying. It and its successors were widely used for private and light aircraft from that moment on. Design and development ADC The Cirrus engine originated in Geoffrey de Havilland's 1924 quest for a powerplant suited to a light two-seat sports biplane which would become the de Havilland Moth. No suitable engine existed at the time combining an appropriate level of power with light weight, low cost and high reliability.
