Grumman Ag-Cat
The Grumman G-164 Ag Cat is a single-engined biplane agricultural aircraft, developed by Grumman in the 1950s. Development In 1955, Grumman preliminary design engineers Joe Lippert and Arthur Koch proposed the design for a "purpose-built" crop-dusting airplane as a means of fulfilling a pressing need in the agricultural community, as well as the perceived need for Grumman to diversify its product lines. The initial market survey indicated that 100 to 200 of this type could be sold each year. Lippert's initial proposal was made under the project name "Farmair 1000". The first G-164, which was built by Grumman (N74054), was equipped with a Continental W670 Series 6A-16 powerplant. The aircraft had its maiden flight on May 27, 1957, with Grumman test pilot Hank Kurt at the controls.Schweizer, William: ''The Ageless Ag Cat: The Forty-year History of the Ag-Cat Agricultural Airplane'', Rivilo Books, 1995 This initial flight test consisted of three short familiarization hops with ...

Pratt & Whitney PT6A
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016.

Cessna 188
The Cessna 188 is a family of light agricultural aircraft produced between 1966 and 1983 by the Cessna Aircraft Company.Christy, Joe ''The Complete Guide to the Single-Engine Cessnas'' 3rd ed, TAB Books, Blue Ridge Summit, Pennsylvania, USA, 1979, pp 119–128 The various versions of the 188 included the AGwagon, AGpickup, AGtruck and AGhusky, along with the AGcarryall variant of the Cessna 185 Skywagon, and constituted Cessna's line of agricultural aircraft. Development In the early 1960s, Cessna decided to expand their already wide line of light aircraft by entering the agricultural aircraft market. They surveyed pilots and operators of other brands of agricultural aircraft to see what features and capabilities these operators were looking for. The resulting aircraft was a conventional single-seat, piston-engined, strut-braced low-wing agricultural airplane. The Cessna 188 borrowed heavily from the Cessna 180, the initial version using the same tail cone and fin structure a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ayres Thrush
The Ayres Thrush, formerly the Snow S-2,Macdonald, 1964. p.138. Aero Commander Ag Commander, and Rockwell Thrush Commander, is an American agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft. It is one of the most successful and long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the first example flew years ago. Typical of agricultural aircraft, it is a single-seat monoplane of conventional taildragger configuration. Originally powered by a radial piston engine, most examples produced since the 1980s have been turboprop-powered. Design and development The Thrush, designed by Leland Snow, first flew in 1956 and before long was being produced in series as the S-2 by the company he founded, Snow Aeronautical. In 1965, the corporation and all of its assets were purchased by the Aero Commander division of Rockwell, which put it into production alongside the CallAir A-9 that it had also acquired, brand ...

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] |
Air Tractor AT-802
The Air Tractor AT-802 is an American agricultural aircraft that may also be adapted into fire-fighting or armed versions. It first flew in the United States in October 1990 and is manufactured by Air Tractor The AT-802 carries a chemical hopper between the engine firewall and the cockpit. In the U.S., it is considered a Type III SEAT, or Single Engine Air Tanker. Development In its standard configuration, the aircraft utilizes conventional landing gear (two main wheels and a tail wheel). However, a number of aircraft have been converted to the Fire Boss aerial firefighting configuration, which utilizes Wipaire 10000 amphibious floats, so that it can land on a traditional runway or on water. The Fire Boss can scoop water from a lake or river for use on a fire. In addition to the AT-802 Fire Boss Factsheet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the fuel-air mixture then combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough energy to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine ex ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
