Pitcairn OP-1
The Pitcairn OP-1 (manufacturer designation: PCA-2) was the first rotary-wing aircraft to be seriously evaluated by any of the world's major air forces. The aircraft was a relatively new type, an autogyro. Pitcairn's model was never put into production for any military. Development The Pitcairn-Cierva Autogiro Company, established by Harold Frederick Pitcairn, designed the PCA-2 based on the ''autogiros'' of Juan de la Cierva. The resulting design had a standard aircraft fuselage and powerplant, with a standard tail. However, it sported short, stubby wings, angled up at the wingtips. Above the cockpit was the rotor, consisting of three blades. The engine usually drove a standard propeller, on a vertical plane, in front of the aircraft. However, the engine could be geared to the horizontal rotor during takeoff or landing. The horizontal rotor, while in flight, did not draw energy from the engine but rather generated lift from airspeed. A minimum speed of 30 mph was needed to ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Pitcairn PA-33
The Pitcairn PA-34 and Pitcairn PA-33, given the United States Navy (USN) designation Pitcairn OP-2 and United States Army (US Army) designation Pitcairn YG-2 respectively were reconnaissance autogyros designed and built in 1936 for evaluation. Design and development The Pitcairn Aircraft Company built and developed auto-gyros under licence from the Cierva Autogiro Company, trading as the Pitcairn-Cierva Autogiro Company from the late 1920s. Interest in the auto-gyro by the USN resulted in the purchase of two Pitcairn PCA-2 autogyros, modified as two-seat observation platforms, designated XOP-1. Trials with the XOP-1s from 1931 had limited success, but included an operational deployment in Nicaragua from June 1932, with the United States Marine Corps (USMC). Following the development of much-improved rotor and control systems, further interest by US armed forces resulted in the Pitcairn PA-33 (YG-2) and Pitcairn PA-34 (XOP-2). These essentially identical aircraft differed main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitcairn Aircraft
The Pitcairn Islands ( ; Pitkern: '), officially Pitcairn, Henderson, Ducie and Oeno Islands, are a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands—Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred kilometres of ocean and have a combined land area of about 47 square kilometres (18 square miles). Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The inhabited islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia), 688 km to the west, as well as Easter Island, 1,929 km to the east. The Pitcairn Islanders are descended mostly from nine British HMS ''Bounty'' mutineers and twelve Tahitian women. In 2023, the territory had 35 permanent inhabitants, rendering it the smallest territory in the world in terms of permanent resident population. History Polynesian settlement Various f ...

Wright R-975
Wright is an occupational surname originating in England and Scotland. The term 'Wright' comes from the circa 700 AD Old English word 'wryhta' or 'wyrhta', meaning worker or shaper of wood.

'', Wright'' was the eleventh most common surname in England. The word ''carpentier'', now "carpenter", was introduced into England in the years after the Norman conquest in 1066 and slowly replaced the traditional name and meaning of wright in most of England.

Juan De La Cierva
Juan de la Cierva y Codorníu, 1st Count of la Cierva (; 21 September 1895 – 9 December 1936), was a Spanish civil engineer, pilot and a self-taught aeronautical engineer. His most famous accomplishment was the invention in 1920 of a rotorcraft called ''Autogiro'',''Aero Digest'', Feb 1939, p. 27 a single-rotor type of aircraft that came to be called autogyro in the English language. In 1923, after four years of experimentation, De la Cierva developed the articulated rotor, which resulted in the world's first successful flight of a stable rotary-wing aircraft, with his C.4 prototype. Early life Juan de la Cierva was born to a wealthy, aristocratic Spanish family, and for a time his father was the war minister. At the age of eight he was spending his pocket money with his friends on experiments with gliders in one of his father's work sheds. In their teens they constructed an aeroplane from the wreckage they had bought from a French aviator who had crashed the plane. The fina ...
