Freel Flying Wing
The Freel Flying Wing was an experimental glider designed and built in the United States during the 1930s. Design and development The Freel Flying Wing was the creation of Charles Lewis Freel (b. 1916). As a student of San Diego High School, in San Diego, California, Freel learned about aerodynamics under the instruction of LeTain Kittredge, in the aircraft rigging/woodshop class. Before his graduation, Freel designed a 36-inch experimental free flight model of a flying wing glider. The model flew well enough to justify moving to a full size piloted glider. In 1933, construction was begun at the San Diego High School woodshop, on a 52-foot span flying wing glider. It was completed in 1937 and licensed with identification mark 18131. Elevons were mounted on the trailing surface and were controlled via a unique worm drive. Several flights were made by Kittredge and Freel over hillsides near San Diego. The glider suffered from poor directional control in flight. After graduation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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'' 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Charles Lewis Freel
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depre ...

San Diego High School
San Diego High School (SDHS) is an urban public high school located on the southern edge of Balboa Park, in San Diego, California, United States. It is the oldest high school in the San Diego Unified School District, one of the oldest public schools in all of California, and the oldest still on its original site. History Russ High (1882–1907) The school was established in 1882, initially named Russ School after lumberman Joseph Russ, who donated the lumber to build the school. The school was built in the Italian Villa style with a low-hip roof, ironwork parapet, and open-bell tower. It consisted of two stories and eight rooms. It initially served elementary students. In 1888 a high school was added, with three teachers. The high school students took over the upper floor; elementary and primary students occupied the lower floor. The first commencement was held in 1889, with four students graduating. In 1893 high school students took over the entire school, which was renamed Rus ...

Free Flight (model Aircraft)
Free flight is the segment of model aviation involving aircraft with no active external control after launch. Free Flight is the original form of hobby aeromodeling, with the competitive objective being to build and launch a self controlling aircraft that will consistently achieve the longest flight duration over multiple competition rounds, within various class parameters. Description The essence of free-flight is that the aircraft have no need for external control, for instance by radio. Aircraft of this type have been flown for over two centuries. They are designed to be inherently stable in flight; if disturbed by a gust of wind or a thermal current they will return automatically to stable flight. Their stability is achieved by a combination of design and trim, - the relationship between centre of gravity, wing and tailplane incidence and rudder setting. With their much lower wing loading, free-flight aircraft fly much more slowly than the engine-powered radio-controlled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worm Drive
A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm gear. The terminology is often confused by imprecise use of the term ''worm gear'' to refer to the worm, the worm wheel, or the worm drive as a unit. The worm drive or "endless screw" was invented by either Archytas of Terentum, Apollonius of Perga, or Archimedes, the last one being the most probable author.Witold Rybczynski, '' One good turn : a natural history of the screwdriver and the screw''. London, 2000. Page 139. The worm drive later appeared in the Indian subcontinent, for use in roller cotton gins, during the Delhi Sultanate in the thirteenth or fourteenth centuries.Irfan Habib''Economic History of Medieval India, 1200–1500'', page 53 Pearson Education Explanation A gearbox designed using a worm and worm wheel is considerably smaller than on ...

Consolidated Aircraft Corporation
The Consolidated Aircraft Corporation was founded in 1923 in aviation, 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors.Yenne 2009, p. 15. Consolidated became famous, during the 1920s and 1930s, for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies. Equally famous was the B-24 Liberator, a heavy bomber which, like the Catalina, saw action in both the Asiatic-Pacific Theater, Pacific and European Theater of Operations, European theaters. In 1943 in aviation, 1943, Consolidated merged with Vultee Aircraft to form Consolidated-Vultee Aircraft, later known as Convair.
