Grob G103 Twin Astir
The Grob G 103 Twin Astir is a glass-reinforced plastic two-seat sailplane that was developed in Germany in the 1970s by Grob Aircraft AG as a counterpart to the single-seat G 102 Astir, then in production. Construction throughout is similar, although to preserve the centre of gravity of the design, the wings were given a slight forward sweep. While many two-seat derivatives of single-seat sailplanes have fixed undercarriage, due to the added space restrictions created by the second seat, Grob devised a novel retraction system for the Twin Astir. The single wheel was designed to rotate 90° sideways before retracting "flat" under the rear seat, resulting in a rather unusual seating position. This was only incorporated in early examples, later on, the wheel was fixed. Factory options offered to customers included whether the front seat should be equipped with flight instruments, and whether water ballast capacity should be installed. Production continued until around 1980, when ... [...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 ...

SZD-50 Puchacz
The PZL Bielsko SZD-50 ''Puchacz'' (Polish: "eagle owl") is a Polish two-place training and aerobatic sailplane. Development The Puchacz was designed by Dipl-Ing Adam Meus based on the prototype SZD-50-1 Dromader. It was intended to serve as the successor to the popular Bocian for training. Its first flight was April 13, 1979. Being a moderately-priced, versatile, modern two-seater with good handling qualities on the ground and in the air, the Puchacz has become a very popular two-seater sailplane in many countries both for ''ab-initio'' and aerobatic instruction. A large number of fatal accidents involving spins have occurred with the Puchacz. Investigations have failed to uncover a common design flaw, but the type's reputation has nevertheless been tainted. Its supporters point out that it was designed to obey faithfully all control inputs - including foolish ones. Partial failures at the rudder bar and control sticks have been known to occur, but Airworthiness Directives hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schleicher ASK 21
The ASK 21 is a glass-reinforced plastic (GRP) two-seat glider aircraft with a T-tail. The ASK 21 is designed primarily for beginner instruction, but is also suitable for cross-country flying and aerobatics, aerobatic instruction. Design and development The ASK 21 was designed by Rudolf Kaiser to replace the popular Alexander Schleicher ASK 13, ASK 13, providing a modern two-seat aircraft bridging the gap between initial training and single-seat performance flying.

Fibreglass
Fiberglass (American English) or fibreglass ( Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non- conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
