The Rolladen-Schneider LS3 is a 15 metre single-seat glider produced by Rolladen-Schneider from 1976 to 1983.
31-639: The LS3 was developed as Rolladen-Schneider's first entry to the new 15-metre competition class created in 1974 by the International Gliding Commission of the Fédération Aéronautique Internationale . Building upon previous experience with the LS1 and LS2 , chief designer Wolf Lemke developed a new fuselage with a larger cockpit and more generous horizontal and vertical stabilisers. Lemke selected

93-415: A glider for either 300 meters or 30 seconds, and "B" level if they made two flights of 45 seconds in straight lines plus one of 60 seconds in an "S" pattern. (It should be remembered that these flights were made by bungee cord launches down hillsides.) In time a "C" level, requiring a five-minute flight, was added. A few years later Fritz Stamer, chief flight instructor of an early gliding school, designed
124-521: A large amount of lead for mass balancing the control surfaces to preclude any risk of flutter. Due to this the LS3 wings are heavy, about 85 kg each semi-span (thus the nickname LS-Blei , a pun exploiting the phonetic similarity in the German language between 'drei' (three) and 'Blei' (lead)). In spite of its weight the LS3 is a nimble climber. It is also less sensitive to rain or dirt than other types with
155-531: A particularly remarkable performance in gliding, or eminent services to the sport of gliding over a long period of time". The first recipient was Tadeusz Góra in recognition of his 577.8 km flight. Its recipients include: National gliding associations (Redirected from National gliding associations ) The sport of gliding is managed in each country by national gliding associations , subject to governmental aviation authorities to varying degrees. Internationally
186-458: A popular glider in the second-hand market although it is seldom found in club fleets, possibly due to the added complexity of flaps and undercarriage. General characteristics Performance Related lists International Gliding Commission The International Gliding Commission ( IGC ) is the international governing body for the sport of gliding . It is governed by meetings of delegates from national gliding associations . It
217-462: A pressure altitude sensor and a Global Navigation Satellite System ( GNSS ) receiver. Data output is in a standard ASCII-based format, the "IGC flight data format". This is used in files with the suffix "IGC" that is specified in detail in Appendix A of the document "Technical Specification for IGC-approved GNSS Flight Recorders". Organisations outside IGC also use IGC-approved flight recorders and
248-465: A relatively thick airfoil profile developed in 1967 by University of Stuttgart Professor Franz Wortmann , the FX 67-K-170 , which offered the structural economy made possible by a tall spar - an important consideration as glass fibre was still the only affordable reinforcement material - as well as good performance for the time. This profile and its sister profile FX 67-K-150 are among the most prolific in
279-464: A security code in the downloaded file of flight data. This code and the file data itself can be checked ("validated") at any time later using a validation program that is posted on the IGC GNSS web site. This validation program checks three things: A public/private key (PPK) encryption system such as RSA or equivalent is used to achieve the validation process above. IGC-approved Recorders also have
310-495: A security device such as a microswitch that operates if the recorder is opened. This enables unauthorised modification to the recorder to be detected and protects the integrity of its output data. There are three levels of IGC-approval: These are allocated by GFAC depending on factors such as the security of the type of FR with respect to the latest IGC FR Specification, the age of the FR design and experience of its characteristics, and
341-487: Is a valuable check that both systems are working correctly. In March 1995, IGC created the "GNSS FR Approval Committee" (GFAC) to test recorders and co-ordinate IGC rules, and Annex B to the Sporting Code for gliders (SC3B) was created for FR rules and procedures. GFAC also issues IGC-approval documents for approved types of FR that are posted on the IGC GNSS web site. For IGC-approval, the recorder design includes

#1732798663253372-494: Is one of several Air Sport Commissions (ASC) of the Fédération Aéronautique Internationale (FAI), or "World Air Sports Federation". FAI is the world body for sporting aviation and the certification of world records for aeronautics and astronautics and was founded in 1905. When the IGC was founded in 1932, it was called CIVV (Commission Internationale de Vol à Voile) and has also been called CVSM (Commission de Vol Sans Moteur). It
403-622: Is the FAI commission responsible for the international competitions, records and badges that apply to gliders and motor gliders . The term "sailplanes" is sometimes used. Hang gliders and paragliders have a separate body called the FAI CIVL Commission, which stands for "Commission Internationale de Vol Libre". The World Gliding Championships are organised every two years or so by the FAI Gliding Commission and
434-534: The D badge became known as the Silver C, and more often today just the Silver Badge. Earning the Silver Badge shows that a glider pilot has achieved an altitude gain of at least 1,000 m, made a five-hour duration flight, and has flown cross-country for a straight-line distance of at least 50 km: these three attainments are usually, but not invariably, achieved in separate flights. The first recipients of
465-618: The Diamond Badge) started in 1949. The Diamond Badge requires three achievements: flying 300 km to a pre-defined goal, going 500 km in one flight (but not necessarily to a pre-defined goal), and gaining 5,000 m in height. Earning all three "diamonds" qualifies the pilot for the FAI registry as a Diamond Badge holder. The first pilot with the Diamond Badge was the American, John Robinson, in 1950, who had also held
496-585: The Gold C and now usually just the Gold Badge) was established in 1935. A pilot who has completed the Gold Badge has flown 300 km, though not necessarily to a pre-defined goal, gained 3,000 m in height and has made a five-hour flight (only one has to be done to count for both the Silver and Gold). Up to this level the badges are registered only by the national gliding associations. The F Badge (now
527-416: The IGC flight data file format. In IGC-approved recorders, GNSS and pressure altitude data is continuously recorded during flight in fixes stored in non-volatile memory inside the recorder. Typical fix intervals, set by the pilot before flight, are 5 seconds for "cruising" flight between turn points, and 1 second near turn points or other points of interest. Pressure altitude figures must be calibrated to
558-522: The International pressure/altitude values of the ICAO ISA (International Standard Atmosphere). Re-calibrations to check any errors from the ICAO ISA are carried out at regular intervals. GNSS lat/long data records the track over ground and in particular whether a particular turn point (TP) has been reached. GNSS altitude data can be compared with pressure altitude data from the recorder and this
589-418: The LS3 good handling and roll rate characteristics. The control system was rigged to reduce the available control stick throw with negative flap settings, therefore giving a measure of in-built protection against overstressing at high speeds. One feature not shared with some competing designs was fully automatic control hookups. The flaperon drives are located at the wing roots, an elegant solution that required
620-503: The Silver C were Wolf Hirth and Robert Kronfeld on 15 February 1931. In 1932 the FAI recognized gliding, and formed a new section: the Commission Internationale de Vol à Voile (CIVV). This eventually took over the role of ISTUS. The FAI decided that the Silver C was sufficiently meritorious to be internationally recognised, and issued the first 300 before turning the awarding over to the national societies. From
651-650: The absolute altitude record. Over 7600 people have achieved this level. The FAI also issues a diploma for a flight of 750 km, and additional ones in increments of 250 km, maintaining lists of the holders of these awards. As of 2019 six people had been awarded a 2000 km diploma The wide variety of records have been defined by the FAI Gliding Commission. The classes of glider have been combined into four groups: Open, 15 metre, World Class and Ultralight. Although female pilots can claim world records in these general categories, there are also additional records in these categories just for female pilots. Because of

#1732798663253682-515: The airfoil after a few years. Owners who corrected this flaw (through profiling) found their LS3s once again equal to the best 15-metre gliders of the day, but by then ASW 20 had become almost ubiquitous in contest entry lists. A variant with separate flaps and ailerons and a slightly taller tail, the LS3a, was introduced in 1978. This version did away with the flaperon mass balancing, making each wing about 10 kg lighter. A span extension to 17-metres
713-587: The beginning the lesser badges were only recorded by local gliding associations, and their criteria varies, although they are usually integrated into organized training programs. For example, in the United States a Bronze Badge is issued for demonstrated pre-cross country flying skills beyond the C level. In Britain a pilot progresses from the B to the Bronze level and then receives an additional endorsement for cross-country training. The E badge (later called
744-573: The gull insignia which were used for these awards and later for the badges. ISTUS (Internationale Studienkommission für motorlosen Flug) , was founded in Frankfurt on 13 June 1930, to record international gliding achievements. The founding nations were Belgium, France, the Netherlands, Hungary, Germany, Italy, and the USA. A series of badges for solo gliding was devised called A, B, C, D etc. Later
775-473: The history of gliding, as they were employed also in the Nimbus-2 , Mini-Nimbus , DG-200 and DG-400 , PIK-20 and PIK-30 , Kestrel , Mosquito , Vega , Jantar and LAK-12 among other types. Unusually for Rolladen-Schneider, the LS3 wings are single-tapered, entailing a slight aerodynamic loss. On the other hand, this geometry went along well with a straight axis for the full-span flaperons which gave
806-712: The host nation. Within FAI, the sport of glider aerobatics is managed by the FAI Aerobatics Commission (CIVA), which stands for "Commission Internationale de Voltige Aérienne" and also deals with powered-aircraft aerobatics In the early 1920s two flying organizations, the Association of the German Model and Gliding Clubs, and the Rhön Soaring Association , determined that pilots would be listed as "A" level if they flew
837-412: The integrity of FR flight data and its resistance to "hacking". An associated body is Organisation Scientifique et Technique du Vol à Voile (OSTIV) which facilitates contact between glider manufacturers and pilots to share experience and opinion The Commission makes awards for great achievements and meritorious service. For gliding it presents: The Lilienthal Medal was instituted in 1938 "to reward
868-757: The number of records the table below only summarises some of the Open Category gliding records as at the beginning of 2008. A full list is available on the FAI web site. With the advent of satellite navigation equipment at an affordable price, the International Gliding Commission of FAI developed a technical specification for approved flight recorders. IGC-approved flight recorders provide precise evidence of position for gliding competitions , national and world records. They replace photographic evidence or ground-based observers to record aircraft position. IGC-approved recorders include
899-420: The same profile. Its thicker wing takes its toll at higher speeds, where it could not keep up with the contemporary ASW 20 , the best 15-metre glider of its generation. One puzzle is how Dick Johnson's flight tests showed essentially identical glide performance for the LS3 and ASW 20 when new, which was not borne out over time. This was attributed to shrinkage over the LS3 spar caps, which resulted in flat spots in
930-539: The sport is co-ordinated by the FAI Gliding Commission .

961-453: Was later developed for this version. Although not very successful due to speed and ballasting limitations, these extensions pioneered a trend that has become extremely popular. Today most new standard and 15-metre class gliders offer tip extensions as an option. The LS3 was superseded in 1983 by the LS6 . Its production run reached 429 exemplars of which two-thirds are of the -a version. It remains
