Yeoman Cropmaster
The Yeoman Cropmaster was an Australian agricultural aircraft developed from the CAC Wackett trainer of World War II. Design and development The type was developed by Yeoman Aviation, a company set up by Kingsford Smith Aviation Services Pty. Ltd. (KSA) at Bankstown Airport to engage in agricultural aircraft production. KSA had obtained a number of Wacketts following the type's retirement from Royal Australian Air Force service and had converted four for agricultural use as KS-3 Cropmasters in the second half of the 1950s. The conversion involved little more than the installation of a hopper located in the rear cockpit of the Wackett, the cutting of a hole in the centre section of the Wackett's wooden wing to allow the dispersal of the chemical load, and re-routing controls to bypass the hopper.Eyre, David. "KINGSFORD SMITH KS-3", ''The Illustrated Encyclopedia of Aircraft in Australia and New Zealand'', p.143. Sunshine Books, Hornsby NSW, 1983. By contrast the YA-1 Cropmaster ...

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 ...

Sasin Spraymaster
The Sasin SA-29 Spraymaster was an agricultural aircraft designed and manufactured in Australia in the 1960s by Sasin Aircraft Service of Goulburn, New South Wales in conjunction with Aerostructures at Sydney's Bankstown Airport. Design and development By the 1960s the converted World War II-vintage types that comprised a large part of the Australian agricultural aircraft fleet were in need of replacement."Sport and Business"''Flight International'', 13 January 1966, p.58 (online archive version) Retrieved: 28 December 2008 Sasin Aircraft Service of Goulburn, an operator of a de Havilland Tiger Moth modified for use as an agricultural aircraft, decided to convert de Havilland Canada DHC-1 Chipmunks for agricultural use and contracted Aerostructures at Bankstown to perform the necessary modifications.Eyre, David.

Piper Pawnee
The PA-25 Pawnee is an agricultural aircraft produced by Piper Aircraft between 1959 and 1981. It remains a widely used aircraft in agricultural spraying and is also used as a tow plane, or tug, for launching gliders or for towing banners. In 1988, the design rights and support responsibility were sold to Latino Americana de Aviación of Argentina. Design and development Most agricultural aircraft before 1949 were converted military aircraft and it was in that year that Fred Weick, based at Texas A&M University, designed a dedicated agricultural aircraft: the AG-1. The AG-1 first flew on 1 December 1950.Peperell/Smith 1987, pp.113-120 During 1953, Fred Weick was approached by Piper to become a consultant on the agricultural version of the PA-18, the PA-18A, in particular to design and test a distributor for dust and seeds. A few weeks later, Piper sponsored Texas A&M University to design a dedicated agricultural aircraft based on the AG-1 but to use as many PA-18A and PA-22 ...

Auster Agricola
The Auster B8 Agricola was a commercially unsuccessful British agricultural aircraft designed for the aerial topdressing market which opened up in New Zealand in the early 1950s. Design Constructed of fabric over a corrosion-proofed steel frame, the design featured a large high-lift low-set monoplane wing, external control cables, fixed tailwheel undercarriage and a somewhat angular fuselage. It had an aft cabin that could seat two passengers, a hopper over the centre of the wing which could hold 750 kg of superphosphate in the topdressing role, or 654 litres of spray as a crop duster. The pilot sat forward of the hopper over the wing leading edge, a position which gave a good field of view compared with the American practice of placing the pilot behind the hopper, though this view was somewhat restricted by the extensive canopy joinery and bulky rear decking. The Agricola's handling was generally described favourably, particularly its slow speed performance and controls, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental IO-470
The Continental O-470 engine is a family of carbureted and fuel-injected six-cylinder, horizontally opposed, air-cooled aircraft engines that was developed especially for use in light aircraft by Continental Motors. Engines designated "IO" are fuel-injected. The family also includes the E165, E185, E225 and the E260 engines, and several specialty variants. It has been in production since 1950.

Tricycle Undercarriage
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

CAC Ceres
The Commonwealth Aircraft CA-28 Ceres was a crop-duster aircraft manufactured in Australia by the Commonwealth Aircraft Corporation (CAC) between 1959 and 1963. The aircraft was a development of the Wirraway trainer of World War II. Development In the 1950s, most crop-dusting aircraft in Australia were conversions of military types that met with varying success. Two CAC types so converted were the Wackett and the Wirraway. Neither type was successful as a crop duster, the Wackett because it was underpowered and the Wirraway because it was not designed for low-level slow-speed flight. Following a market survey conducted together with ICI, CAC determined there was a need for a purpose-built aircraft optimized for agricultural work. Once the board approved the project, a number of surplus Wirraways were purchased from the RAAF for use in the production of this new aircraft.CAC purchased a total of 61 surplus Wirraways. For example, a batch of 5 purchased on 2 May 1958: Sales Advic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hartzell Propeller
Hartzell Propeller is an American manufacturer that was founded in 1917 by Robert N. Hartzell as the Hartzell Walnut Propeller Company. It produces composite and aluminum propellers for certified, homebuilt, and ultralight aircraft. The company is headquartered in Piqua, Ohio.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 84. BAI Communications.
