John Thorp
John Willard Thorp (June 20, 1912 – April 18, 1992) was an American aeronautical engineer who made significant contributions to aircraft design throughout his life. Born in French Camp, California, John Thorp grew up from age four in the historic Locke family home in Lockeford, California. He was educated in the Lockeford and Lodi public schools, and the Boeing School of Aeronautics in Oakland, California. Thorp worked on the Boeing 247 final assembly line and then returned to teach at the Boeing School. Starting flying in 1929, he received his private license in 1930 and by 1935 had flown 30 different types of aircraft in over 200 flying hours. By 1946 he had over 600 flight hours in 62 different aircraft types. Thorp started designing personal aircraft at the Boeing School. As Lockheed Assistant Preliminary Design Engineer, he was responsible for the preliminary design of the P2V "Neptune", Naval patrol bomber. In 1946 the famous P2V "Truculent Turtle" set the unrefuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, Air propulsion, avionics, materials science, ...

Lockheed Little Dipper
The Lockheed Model 33 Little Dipper, also known as Air Trooper, was an American single-seat monoplane, designed by John Thorp and built by Lockheed at Burbank, California. Flown in 1944 and offered to the Army as a "flying motorcycle", it was evaluated as a potential entry for Lockheed into the civilian market, but the program was cancelled before the second prototype was completed. Design and development The design of the Model 33 originated with a private venture for a two-seat light aircraft by John Thorp, a Lockheed engineer.Francillon 1982, pp. 256-257. In April 1944, the company agreed to build the aircraft as the Lockheed Model 33. Due to wartime restrictions on materials, the company gained the interest of the United States Army in the aircraft as an "aerial flying motorcycle" to equip a "flying cavalry" under the name Air Trooper. The Army, willing to entertain the concept, authorized Lockheed to build two prototypes of the Model 33. The Model 33 was of ordinary light ...

Thorp T-15
The Fletcher FU-24 is an agricultural aircraft made in New Zealand. One of the first aircraft designed for aerial topdressing, the Fletcher has also been used for other aerial applications as a utility aircraft, and for sky diving. Design and development In the early 1950s New Zealand topdressing operators were in the U.S. seeking a replacement for war surplus De Havilland Tiger Moths which formed the backbone of the industry. To answer the New Zealand request US aeronautical engineer and light aircraft enthusiast John W. Thorp, working for the Fletcher Aviation Corporation, conceived the T.15 with design elements taken from his earlier T.11 Sky Scooter including an all-moving horizontal tailplane but with a wing design similar to that of his Fletcher FD-25 Defender. Further design work was carried out by Gerald Barden of the Fletcher Aviation Corporation under Thorp's direction. A group of New Zealand top dressing operators gathered a hundred purchase options for the desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorp T-14
The Fletcher FD-25 Defender was a light ground-attack aircraft developed in the United States in the early 1950s. Design and development Designed by John Thorp, the Defender was a conventional low-wing cantilever monoplane with fixed tailwheel undercarriage. Provision was made for two machine guns in the wings, plus disposable stores carried on underwing pylons. Construction throughout was all-metal, and the pilot sat under a wide perspex canopy. Operational history Three prototypes were built, two single-seaters and a two-seater, but no orders were placed by the US military. In Japan, however, Toyo acquired the rights to the design, and built around a dozen aircraft, selling seven (five single-seater attack versions and two two-seat trainers) to Cambodia,Grandolini 1988, p. 39. and four to Vietnam. One example (FD-25B JA3051) served with the Royal Thai Police. Survivors One example (FD-25B N240D) remains in an airworthy condition today and appeared at the EAA AirVenture Oshko ...

Thorp T-13
__NOTOC__ The Fletcher FL-23 was an American two-seat liaison or observation aircraft designed and built by the California-based Fletcher Aviation Corporation. It was entered into a competition and lost against the Cessna 305A as a liaison or observation aircraft for the United States Army. Development The FL-23 prototype was designed and built as a private venture, it was a high-wing cantilever monoplane with an all-moving tailplane mounted at the top of the fin. It had a fixed tricycle landing gear and powered a 225-hp (168 kW) Continental E225 piston engine. It had room for a pilot and observer in tandem; the observer had an unusual acrylic plastic enclosure to give an all-round visibility. Operational history The US Army issued the specification for a two-seat liaison and observation monoplane and the prototype was entered into the competition. During trials the aircraft was badly damaged in a flying accident when it lost its tail, and was withdrawn from the competiti ...

Thorp T-12
''Thorp'' is a Middle English word for a hamlet or small village. Etymology The name can either come from Old Norse ''þorp'' (also ''thorp''), or from Old English (Anglo-Saxon) ''þrop''. There are many place names in England with the suffix "-thorp" or "-thorpe". Those of Old Norse origin are to be found in Northumberland, County Durham, Yorkshire, Lincolnshire, Cambridgeshire, Norfolk, and Suffolk. Those of Anglo-Saxon origin are to be found in southern England from Worcestershire to Surrey. Care must be taken to distinguish the two forms. Variations of the Anglo-Saxon suffix are "-throp", "-thrope", "-trop" and "-trip" (e.g. Adlestrop and Southrope). Old English (Anglo-Saxon) ''þrop'' is cognate with Low-Saxon ''trup''/''trop''/''drup''/''drop'' as in Handrup or Waltrop, Frisian ''terp'', German ''torp'' or ''dorf'' as in Düsseldorf, the 'Village of the river Düssel', and Dutch ''dorp''. It also appears in Lorraine place-names as ''-troff'' such as Grosbliede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorp T-211
The T-211 is a light aircraft designed in the US by John Thorp in 1945. It is a low-wing monoplane of conventional layout with fixed tricycle undercarriage and a sliding canopy. John Thorp developed the Sky Scooter with lessons learned from developing the Lockheed Little Dipper project in 1944. It bears some family resemblance to the Piper Cherokee, a design that Thorp later contributed to significantly. Development Thorp constructed eight prototypes, and had the design certified by the FAA, but was unable to find a foothold in the Cessna-dominated post-war US market. The original prototypes were powered by a 65 hp Lycoming engine. Novel features of the Sky Skooter include an all movable horizontal stabilizer and externally ribbed wings and tailplane. The wings were corrugated to impart stiffness, each wing needing only three internal ribs. This feature simplified construction, reduced the number of rivits (and weight), and helped control the spanwise flow of air over the wings. ...

The Indus ( ) is a transboundary river of Asia and a trans-Himalayan river of South and Central Asia. The river rises in mountain springs northeast of Mount Kailash in Western Tibet, flows northwest through the disputed region of Kashmir, Quote: "Kashmir, region of the northwestern Indian subcontinent. It is bounded by the Uygur Autonomous Region of Xinjiang to the northeast and the Tibet Autonomous Region to the east (both parts of China), by the Indian states of Himachal Pradesh and Punjab to the south, by Pakistan to the west, and by Afghanistan to the northwest. The northern and western portions are administered by Pakistan and comprise three areas: Azad Kashmir, Gilgit, and Baltistan, ... The southern and southeastern portions constitute the Indian state of Jammu and Kashmir. The Indian- and Pakistani-administered portions are divided by a "line of control" agreed to in 1972, although neither country recognizes it as an international boundary. In addition, China becam ...

Lycoming O-145
The Lycoming O-145 is a family of small, low-horsepower, four-cylinder, air-cooled engines. It was Lycoming Engines' first horizontally opposed aircraft engine and was produced from 1938 until the late 1940s. The family includes the reduction-geared GO-145.Christy, Joe: ''Engines for Homebuilt Aircraft & Ultralights'', pages 64-65 TAB Books, 1983. The O-145 received its Approved Type Certificate on 13 Jun 1938. Design and development The O-145 was produced in three major versions, the O-145-A rated at , the -B rated at , and -C rated at . The "B" model was the major production model, with the "A" and "C" produced in much smaller quantities. All models of the series had the same bore, stroke, and displacement, additional horsepower being generated by increasing compression ratio and maximum rpm. All use a Stromberg NA-S2 or NA-S2A or Marvel MA-2 or MA-2-A carburetor. The dual ignition versions use two Scintilla SF-4L, SN4LN-20 or -21, Superior SMA-4 or Edison-Splitdorf RMA-4 m ...
