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.
Following the transfer of ownership, subtype designations and specifications changed slightly. LS8-a : as the previous –a model except the spar is not reinforced for span extension. LS8-s : corresponds to the previous LS8-18 model, with a larger main undercarriage, the wing further reinforced for an increased maximum weight of 575 kg in the ...
LS7 may refer to: Vehicles. General Motors LS7, a small-block V8 gasoline engine; Rolladen-Schneider LS7, a 1988–1993 German high-performance single-seat ...
The design of the LS4 was influenced mainly by the experience Rolladen-Schneider had gained with the LS2 and LS3 flapped gliders. Wolf Lemke returned to a double-tapered wing planform, giving it a larger area comparatively to the LS1 and LS2, and enlarged all control surfaces: the ailerons were elongated and brought further inboard and the tailplane span was increased.
The type consolidated Rolladen-Schneider's reputation for well rounded, easy to fly gliders that do well in any conditions, being known for its superb handling, tolerance of piloting technique and environment (turbulence, rain, contamination by insects) as well as for good glide ratios over a wide speed range.
Rolladen-Schneider LS4 (video) A glider sails over Gunma, Japan. A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). [1] [2] This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically ...
The LS7.R engine is a variation of the LS7 used in the highly successful C6.R American Le Mans Series racecar. It was crowned as Global Motorsport engine of the year by a jury of 50 race engine engineers on the Professional Motorsport World Expo 2006 in Cologne, Germany. [108] LSX. LSx is also used to denote any LS engine. Chassis with LSX engine
A span extension to 17-metres 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 ...
