27-512: Akaflieg Köln initiated in 2000 the concept design for the AFK1. One of the design goals was to use as many standard LS components as possible in order to lower the development costs. This and the large contribution of Wolf Lemke , who performed the aerodynamic and structural calculations, led to Rolladen-Schneider bestowing the type designation LS11 upon the Akafliegers' project.

216-613: Is similar to the LS4 cockpit, and both seats have enough leg and elbow room to preclude the mutual interference too often encountered in tandem sailplanes. The maximum cockpit load is 230 kg. The large canopy is a single unit which integrates the instrument panels into the canopy frame. It is hinged at the back in the Piontkowski fashion and opens with an upward and rearward movement. The practicality of this concept for large glider canopies has already been tested by Akaflieg Köln through

243-641: The German Aerospace Center (DLR) , while the results of the research are presented at the winter meetings. The Idaflieg also offers many events and courses to its members such as the specification, design and certification of aeroplanes. The quality of additional education provided by the Akafliegs is widely respected and so German glider manufacturers recruit almost exclusively from the Akafliegs. Members have to devote approximately 150 to 300 man-hours annually in order to be able to fly with

297-539: The Akafliegs. The cost of flying for these members is usually much lower than at other gliding clubs. American Universities have also implemented programs similar to the Akafliegs but based around the American style of teaching, Penn State 's AERSP 404H is one example of this implementation. There are also academical gliding clubs with other focus than building aircraft, like the Akaflieg Frankfurt which

324-573: The Basis of Aviation) in 1889. This described the basics of modern aerodynamics and aircraft construction. Lilienthal then made many successful flights starting in 1891. However attention then shifted to powered flight after World War I . Gliding re-emerged as a sport after the war because the building of powered aircraft was restricted in Germany by the Treaty of Versailles . The main originator of

351-621: The Nazi period some Akafliegs escaped regulation for a while through the patronage of the Deutsche Versuchsanstalt für Luftfahrt (DVL) , a forerunner of the present-day German Aerospace Center (DLR) , however shortly before World War II the akafliegs were forced to integrate into the NS-Deutsche Studentenbund (Nazi-students-federation) . The projects at this time mainly had a military application. After

378-621: The ailerons remain in a neutral position, enabling slower landing speeds with good control response. Multiblade airbrakes extend from the upper surfaces of the wings to give ample glidepath modulation. General characteristics Performance Akaflieg Akaflieg is an abbreviation for Akademische Fliegergruppe , groups of aeronautical engineering students from individual German universities of technology and Technische Hochschulen , pre and postwar, who design aircraft, often gliders. Otto Lilienthal published his book Der Vogelflug als Grundlage der Fliegekunst (Birdflight as

405-530: The aim of scientific and practical education. The first groups were formed in 1920 in Aachen, Darmstadt and Berlin-Charlottenburg, but others soon followed. Many of the first members had been pilots in the German Air Force. However it was the love of flying rather than militarism or nationalism that motivated them. As a result a fraternal spirit was created that has been maintained to this day. During

432-582: The gliding movement was Oskar Ursinus , who in 1920 organised the first contest, known as the Rhön-Contest, on the Wasserkuppe . Thereafter the contest was held annually. Students of Technische Hochschulen brought gliders which they had developed and built themselves for testing to these contests. An esprit de corps developed known as Rhöngeist . These informal beginnings caused the formation of groups of engineers at Technische Hochschulen with

459-493: The horizontal stabiliser was increased; the vertical stabiliser was made both taller and longer, to provide the required steering power while keeping the top of the vertical fin at a height comfortable for the assembly of the horizontal empennage. The cockpit, manufactured from carbon and aramid reinforced plastic, was designed to accommodate pilots up to two meters tall. Available space is sumptuous for both pilots, exceeding that of all comparable production gliders. The front seat

486-407: The main wheel. A fixed tail wheel is also provided. This undercarriage scheme simplifies ground handling, since fuselage dollies are not required. The main wheel is located near the glider's empty centre of gravity. All controls connect automatically upon assembly in the habitual LS way. The control system is built mostly from standard LS parts. The wings are connected by two main pins inserted into

513-431: The modification of three Scheibe SF-34 gliders. The hinge is a carbon reinforced element able to withstand wind speeds up to 75 km/h when open and was designed to sever the tubing and wiring looms from the instrument panels upon emergency release in flight. The airplane stands on a sprung, retractable main undercarriage with a six-inch hub, and a nose wheel which is likewise sprung and retracts simultaneously with

540-400: The new Two-Seater competition class. Water ballast bags inside the wings enable loadings up to 50 kg/m. Two ballast tanks integrated into the rudder fin will keep the centre of gravity within its optimum range, compensating for ballast changes and heavier pilots. The empty weight was a serious design concern for reasons beyond mere ease of ground handling. As the scope for increasing

567-649: The project is to design and build a thoroughly capable school glider with top performance for cross-country training, record flying and competition. The LS11 gets its performance from an extended Rolladen-Schneider LS6 wing. After the Akaflieg Darmstadt D-41 demonstrated the feasibility of a high performance, multiplace glider based on the LS6 wing, the Köln Akafliegers felt they could profit from and improve upon that design. The wing structure

621-465: The tongue-and-fork spar ends, as in the LS6 and subsequent LS types. A low landing speed is essential for a trainer. Wolf Lemke and Siegfried Piontowski decided to depart from the typical LS system in which ailerons and flaps act as flaperons , using a mixed schedule as featured in the Schleicher ASW 27 . In landing configuration the flaps assume a deflection of about 75 degrees while

The aim of the Akafliegs is the development, design and construction of aeroplanes, especially gliders and scientific research into flight. Much of the practical work is done at the summer meetings of the Idaflieg in co-operation with

675-522: The wing area was limited, since it originated on a single-seat design, the Akafliegers strove to achieve an empty mass as low as possible, in order to keep the wing loading of the shorter 18 meter span within reasonable limits. Some parts of the fuselage were adapted from existing production types, such as the tail boom of the LS4 and the empennage of the LS8 . Considerable redesign was required, however. The span of

702-771: Was redesigned and resembles somewhat the Rolladen-Schneider LS9 structure. The wings, almost entirely made of Carbon fibre Reinforced Plastic, were manufactured at the Rolladen-Schneider factory in Egelsbach in mid-2001, while the span extensions were built in the moulds developed by the Darmstadt group for the D41. The LS11 prototype was featured as a work in progress at the 2003 and 2005 AERO Friedrichshafen exhibitions in Germany. The maiden flight

729-536: Was to be followed by a comprehensive flight test programme in 2006, to be carried out at Akaflieg Köln's home airfield, Dahlemer Binz in the Eifel region in Germany. The LS11 is slated for production by the Slovenian aircraft manufacturer AMS-Flight . The LS11 is expected to have up to four interchangeable sets of wingtips for spans between 18 and 21 meters. The prototype currently has a 20-meter span in keeping with
