Piper PA-38 Tomahawk
The Piper PA-38-112 Tomahawk is a two-seat, fixed tricycle gear general aviation airplane, originally designed for flight training, touring and personal use. Design and development The Tomahawk is a single-engined low-wing cantilever monoplane with a T-tail and an enclosed cabin for two. It has a fixed tricycle landing gear and is powered by a Lycoming O-235 four-cylinder piston engine with a twin-bladed tractor propeller. The Tomahawk has two front-hinged doors for access to the cabin. The Tomahawk was Piper Aircraft, Piper's attempt at creating an affordable two-place trainer. Before designing the aircraft, Piper widely surveyed flight instructors for their input into the design. Instructors requested a more Spin (flight), spinnable aircraft for training purposes, since other two-place trainers such as the Cessna 150 and Cessna 152, 152 were designed to spontaneously fly out of a spin. The Tomahawk's NASA GA(W)-1 Richard T. Whitcomb, Whitcomb airfoil addresses this requirem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Air Force Cadets
The Australian Air Force Cadets (AAFC), known as the Air Training Corps (AIRTC) until 2001, is a Federal Government funded youth organisation. The parent force of the AAFC is the Royal Australian Air Force (RAAF). Along with the Australian Army Cadets (AAC) and the Australian Navy Cadets (ANC), it is part of the Australian Defence Force Cadets. History Founding of the Air Training Corps The Air Training Corps (ATC), predecessor to the Australian Air Force Cadets, was formed by the Australian War Cabinet in February 1941 as a cadet corps part of the Royal Australian Air Force (RAAF) reserves. The main aims of the force were to train young men from ages 16 to 18 to join the RAAF in the midst of World War II, and for young men to increase their "air knowledge" and interest in the RAAF. The personnel strength of the ATC peaked at 12000 cadets in training in 1943. Post-War Period and Brief Disbandment After the end of World War II, the ATC was scaled down from the lack of dem ...

Alpha 2000
The Alpha Aviation Alpha 2000 is a two-seat, all-metal training and general aviation aircraft, designed by Chris Heintz and built in Hamilton, New Zealand. It continues the successful French Apex Aircraft's Robin R2000 series acquired upon Apex's purchase of the Avions Robin company. History 1971–1994 The original Avions Robin HR200 was designed by Christophe Heintz, to supplement the earlier Avions Robin designs of Jean Délémontez who also designed the popular post war wooden Jodel. The HR 200 prototype first flew on 19 July 1971, and entered production in 1973. The R2000 Alpha name was applied to a new aircraft which shared the fuselage of the HR 200, but had all new wing and tail surfaces, to allow aerobatics. The prototype R2000 Alpha flew on 15 January 1976 and production followed in 1977 to 1983. The aircraft features side-by-side seating, an innovative control stick mechanism which reduces the risk of blockage and an unusually large payload for an aerobatic air ...

Aerotec A-132 Tangará
The Aerotec A-132 Tangará (originally the Uirapuru II) was a Brazilian military trainer aircraft developed from the A-122 Uirapuru of the 1960s. Design and development The A-132 Tangará was developed in response to a request from the Brazilian Air Force. Compared to its predecessor, the Uirapuru II had a longer fuselage, greater wingspan, larger fin, more powerful engine, and a redesigned, flat-sided fuselage. A similar aircraft with a less powerful engine was planned for the civil market. The prototype first flew on 26 February 1981. The Air Force originally had the intention to order 100 units but after a decision that the primary trainer should have tandem seats, the project was abandoned. The only orders came from the Bolivian Air Force, which ordered 6 units in 1986 and flew them until 1992. The prototype was given to the Air Force Technical Institute in 1990 where it was used for tests until 2004. It was then passed on to the Aeroclube de Sao Jose dos Campos, where it w ...

Indicated Airspeed
Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system and displayed by the airspeed indicator (ASI). This is the pilots' primary airspeed reference. This value is not corrected for installation error, instrument error, or the actual encountered air density, being instead calibrated to always reflect the adiabatic compressible flow of the International Standard Atmosphere at sea level. It uses the difference between total pressure and static pressure, provided by the system, to either mechanically or electronically measure dynamic pressure. The dynamic pressure includes terms for both density and airspeed. Since the airspeed indicator cannot know the density, it is by design calibrated to assume the sea level standard atmospheric density when calculating airspeed. Since the actual density will vary considerably from this assumed value as the aircraft changes altitude, IAS varies considerably from true airspeed (TAS), the relative ve ...

Piston Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more Reciprocating motion, reciprocating pistons to convert high temperature and high pressure into a Circular motion, rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition engine, spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition engine, compression-ignition (CI) engine, where the air within the cylinder is compressed, Adiabatic process, thus heating it, so that the heated air ignites fuel that is injected diesel engine, then or hot-bulb engine, earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat-four
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than a straight-four engine. There is a minor, secondary unbalanced rotational torque pulse in the plane of the pistons, when a piston pair at one end of the engine is at TDC and the other pair at BDC. The TDC pair creates a torque greater than the BDC pair, so the net unbalanced torque pulse is the difference. The difference in TDC vs BDC inertial forces is explained in the Engine balance section. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stall Strips
A stall strip is a small component fixed to the leading edge of the wing of an airplane to modify its aerodynamic characteristics.Crane, Dale: ''Dictionary of Aeronautical Terms'', third edition, page 487. Aviation Supplies & Academics, 1997. These stall strips may be necessary for the airplane to comply with type certification requirements. A stall strip typically consists of a small piece of material, usually aluminium, triangular in cross section and often 6-12 inches (15–30 cm) in length. It is riveted or bonded to the wing’s leading edge. Some airplanes have one stall strip on each wing. Some airplanes have only one stall strip on one wing. Operation A stall strip initiates flow separation on a region of the upper surface of the wing during flight at high angle of attack In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a Airfoil#Airfoil terminology, reference line on a body (often the chord (aircraft), chord line of an airfoil) ...

Lightening Holes
Lightening holes are holes in structural components of machines and buildings used by a variety of engineering disciplines to make structures lighter. The edges of the hole may be flanged to increase the rigidity and strength of the component. The holes can be circular, triangular, elliptical, or rectangular and should have rounded edges, but they should never have sharp corners, to avoid the risk of stress risers, and they must not be too close to the edge of a structural component. Usage Aviation Lightening holes are often used in the aviation industry. This allows an aircraft to be as lightweight as possible, retaining the durability and airworthiness of the aircraft structure. Maritime Lightening holes have also been used in marine engineering to increase seaworthiness of the vessel. Motorsports Lightening holes became a prominent feature of motor racing in the 1920s and 1930s. Chassis members, suspension components, engine housings and even connecting rods were dril ...
