Glaser-Dirks DG-600
The Glaser-Dirks DG-600 is a glider manufactured by Glaser-Dirks as a successor to the DG-202 and DG-400 series of gliders where carbon fiber reinforced plastics was used. Design and development The DG-600 fuselage is based on the fuselage of the DG-400 but with a more slender tailboom which also incorporates a tailfin ballast tank with a capacity of 7 liters. The design of the canopy and the instrument panel is practically the same as on other DG gliders. The control surfaces incorporate flaperons which serve as both flaps and ailerons. The wing has a newly designed thinner airfoil and higher aspect ratio than previous types of DG gliders. This gives a higher performance but at a cost of worse slow-speed characteristics, making it less suitable for gliding competitions with frequent gaggles in thermals. The same problem is also noticeable on LS-7 and ASW-24 gliders, where improved performance was to be achieved with thinner airfoils. The negative effects (i.e. a stall w ...

1980s German Sailplanes
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Alexander Schleicher ASW 24
The ASW 24 is a modern single-seat high-performance composite Standard Class sailplane. It is manufactured in Germany by Alexander Schleicher GmbH & Co. History The ASW 24 was designed by Schleicher's Gerhard Waibel, with Delft University professor Loek Boermans undertaking the role of aerodynamicist. The prototype made its first flight in 1987 and entered serial production later the same year. It nominally remained in production until 2000, although only a score were built in the mid-to-late 1990s. It entailed a large development effort, as it was a complete departure from the preceding ASW 19 and pioneered several successful innovations. The fuselage, airfoils, wings and empennage were completely new, as well as many systems, e.g. the electrical ballast management. The structure employed a large amount of the then still exotic carbon fibre. The OSTIV Award-winning ''safety cockpit'' made use of an organic shape, tall sidewalls, crumple zones and exotic aramid fibres for ...

Rolladen-Schneider LS7
The Rolladen-Schneider LS7 is a high-performance Standard Class single-seat sailplane produced by Rolladen-Schneider Flugzeugbau GmbH from 1988 to 1993. Design and development The LS7 was developed as the successor to the LS4, one of the most successful gliders ever produced. In a departure from the design philosophy of the LS4, Rolladen-Schneider set out to design the LS7 as an uncompromised competition machine, seeking the highest performance possible with the technology of the time. Designer Wolf Lemke specified a highly laminar wing profile and developed a high aspect ratio wing. Carbon fibre was extensively used in the construction, along with aramid fibre, to ensure enough strength in spite of slender structural elements and increased loadings. The aileron drive bellcranks were entirely concealed within the wings, with a mere 30mm of usable height at the trailing edge. The LS7 prototype flew for the first time in the autumn of 1987, and serial production started in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flaperon
A flaperon (a portmanteau of flap and aileron) on an aircraft's wing is a type of control surface that combines the functions of both flaps and ailerons. Some smaller kitplanes have flaperons for reasons of simplicity of manufacture, while some large commercial aircraft such as the Boeing 747, 767, 777, and 787 may have a flaperon between the flaps and aileron. The 787 has a configuration known as a SpoileFlaperon that combines the action of spoilers, flaps and ailerons into one control surface. Operation In addition to controlling the roll or bank of an aircraft, as do conventional ailerons, both flaperons can be lowered together to reduce stall speed, similarly to a set of flaps. On a plane with flaperons, the pilot still has the standard separate controls for ailerons and flaps, but the flap control also varies the flaperon's range of movement. A mechanical device called a "mixer" is used to combine the pilot's input into the flaperons. While the use of flaperons rath ...

Carbon Fiber-reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other additi ...

Glaser-Dirks DG-400
The Glaser-Dirks DG-400 is a single-seat self-launching motorglider that was produced by Glaser-Dirks between 1981 and 1992. It was the first self-launching motorglider with retractable engine and propeller to be produced in large numbers. Development The cost of carbon-fibre had fallen enough in the late 1970s to allow its use in the wing spars of high-performance gliders. Glaser-Dirks introduced a carbon wing variant of the DG-200 about this time. Designer Wilhelm Dirks realised that the span, strength and very low weight of this wing allowed for a self-launching engine to be carried in the glider without an unacceptable penalty when soaring in weak conditions. The DG-400 was created as a result. It first flew in May 1981. The DG-400 uses the wings and most systems of the DG-202. It has a modified fuselage with a slightly enlarged tailcone and carbon fibre reinforcements to accommodate the engine, which is a relatively large unit with electric starter and electric retract ...
