cost of new glider very high (top of the range 18 m turbo with instruments and trailer €250,000) but it is long lasting (up to several decades), so active second-hand market; typical cost is from €2,000 to €145,000 [9]
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.
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 SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1] [2] [5]
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.
At that time the Schweizer SGS 1-23 was the only sailplane in production in the United States and demand for it had dropped off, due to its high price. At the same time the number of people participating in soaring had increased and there was a clear market for a low cost sailplane. [2] Design goals for the new glider included: [2] available as ...
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 The LS3 was superseded in 1983 by the LS6.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 ...
The published glide ratio of the Atlas is 40:1. Best glide speed is 88 km/h (55 mph, 48 kn); V NE is low for a contemporary glider at 180 km/h (110 mph, 97 kn). [citation needed] An improved variant, the TST-10MB was released in spring 2008.
