Koolhoven F.K.49
The Koolhoven F.K.49 was a photographic survey aircraft built in the Netherlands in 1935. Design and development The F.K.48 was a high-wing cantilever monoplane of conventional design with twin engines carried in nacelles on the leading edges. Usually fitted with fixed, tailwheel undercarriage, a floatplane version was also developed. The aircraft carried an onboard darkroom. Three examples were purchased by the Dutch Army, but only one of these was ever delivered, the other two were destroyed before completion when the Koolhoven factory was bombed by Germany on 10 May 1940. Others were purchased in small numbers by Turkey, Hungary, and Finland. Operational history The sole example delivered to the Dutch Army was eventually used as a general utility type, serving as an air ambulance, parachute trainer, and general transport. The Turkish F.K.49A, powered by Fairchild Ranger engines, had a short service life before the engines caught fire in flight, resulting in a fatal crash. ...

Finnish Coast Guard
The Finnish Border Guard (; ) is the agency responsible for enforcing the security of Finland's borders. It is a military organisation, subordinate to the Ministry of the Interior in administrative issues and to the President of Finland in issues pertaining to his authority as Commander-in-Chief (e.g. officer promotions). The agency has police and investigative powers in immigration matters and can independently investigate immigration violations. The Border Guard has search and rescue (SAR) duties, both maritime and inland. Missions inland are often carried out in co-operation with local fire and rescue departments or other authorities. The Finnish Border Guard consists of 3,800 active duty personnel. Upon mobilization, it would be wholly or partly incorporated into the Finnish Defence Forces and its strength increased with reservists who have served their conscription in the branch. The mobilized strength of the Finnish Border Guard is 12,600 servicemen. The Finnish-Russian b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Dutch Special-purpose 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.

Koolhoven Aircraft
N.V. Koolhoven was an aircraft manufacturer based in Rotterdam, Netherlands. From its conception in 1926 to its destruction in the Blitzkrieg in May 1940, the company remained the second major Dutch aircraft manufacturer (after Fokker). Although many of its aircraft were as unsuccessful economically as they were brilliant from a design standpoint, the company managed to score several 'hits', amongst them the Koolhoven FK-58, FK-58 single-seat monoplane fighter, the Koolhoven F.K.50, FK-50 twin-engine passenger transport, and the Desoutter Mk.II, FK-41, built in England under licence by Desoutter. History In 1920, aircraft designer Frederick Koolhoven, Frederick 'Frits' Koolhoven returned from England to his native Netherlands. The postwar years had not been good to him; the British Aerial Transport, British Aerial Transport Company for which he was chief designer went bankrupt and all other manufacturers were struggling for survival too hard to think of hiring.

De Havilland Gipsy Major
The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types. Engines were produced by de Havilland in the UK and by the Australian arm of the company, de Havilland Australia, the latter modifying the design to use imperial measures rather than the original metric measurements. Design and development The engine was a slightly modified Gipsy III, which was effectively a de Havilland Gipsy engine modified to run inverted so that the cylinders pointed downwards below the crankcase. The Major was also bored-out (118 mm from 114 mm) compared to the Gipsy III, increasing displacement from 5 L to 6.1 L. The inverted configuration allowed the propeller shaft to be kept in a high position without having the cylinders blocking the pilot's forward view over the nose of the airc ...

Dutch Army
The Royal Netherlands Army ( nl, Koninklijke Landmacht) is the land branch of the Netherlands Armed Forces. Though the Royal Netherlands Army was raised on 9 January 1814, its origins date back to 1572, when the was raised – making the Dutch standing army one of the oldest in the world. It fought in the Napoleonic Wars, World War II, the Indonesian War of Independence, and the Korean War and served with NATO on the Cold War frontiers in West-Germany from the 1950s to the 1990s.

Darkroom
A darkroom is used to process photographic film, to make prints and to carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water. Darkrooms have been used since the inception of photography in the early 19th century. Darkrooms have many various manifestations, from the elaborate space used by Ansel Adams to a retooled ambulance wagon used by Timothy H. O'Sullivan. From the initial development of the film to the creation of prints, the darkroom process allows complete control over the medium. Due to the popularity of color photography and complexity of processing color film (''see C-41 process'') and printing color photographs and also to the rise, first of instant photography technology and later digital photography, darkrooms are dec ...
