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 ... [...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 n ...

RWD (aircraft Manufacturer)
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym. History They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (''Sekcja Lotnicza Koła Mechaników Studentów''), where they manufactured their first designs. From 1926 they designed several aircraft alone ( Drzewiecki JD-2 and WR-1), in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Okęcie aerodrome, today's Warsaw International Airport, founded by the LOPP paramilitary organizati ...

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 G ...

RWD 2
The RWD 2 was a 1929 Polish single-engine high-wing monoplane sports plane constructed by the RWD team. Development The RWD 2 was 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 a development of their first design RWD-1. Its feature was a unique, fish-shaped fuselage, with good aerodynamics, but without a direct view forward from the pilot's seat. For this reason, they were later nicknamed: ''blind mice''. The first prototype (registration SP-ACE) was completed and flown by the designer Jerzy Drzewiecki in July 1929. Since it appeared successful in sports flying, three more RWD-2s were built in 1930 (registration SP-ADJ, -ADG, -ADH). Use In August–September 1929, Franciszek Żwirko and Stanisław Wigura flew the prototype across Europe, on the 5000 km Warsaw-Paris-Barcelona-Warsaw route (it was the first long foreign raid of the Poli ...

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] |
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. The Aircraft Disposal Company, also known as Airdisco and ADC, were producing the low-cost Airdisco V8 which had been developed by Frank Halford fr ...

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 wa ...
