The '''Schleicher ASW 17''' is a single-seat Open Class [[Engineering:Glider (sailplane)|sailplane]] that was built by the German manufacturer Alexander Schleicher GmbH & Co and first flew in 1971. It replaced the [[Engineering:Schleicher ASW 12|ASW 12]], and was replaced in 1981 by the [[Engineering:Schleicher ASW 22|ASW 22]].

==Design and development==
The ASW 17 was designed by [[Biography:Gerhard Waibel (engineer)|Gerhard Waibel]], supposedly as a development of the [[Engineering:Schleicher ASW 12|Schleicher ASW 12]], but was an entirely new design. The wing is in four sections. The camber-changing flaps are connected to the ailerons. It has Schempp-Hirth airbrakes plus an optional tail parachute. It first flew on 17 July 1971 and 55 were built before production stopped in 1976.

The ASW17 was succeeded by the [[Engineering:Schleicher ASW 22|ASW22]].

==Variants==
In addition to the regular ASW 17, there is an ASW 17S which was a 21-metre span version built in 1973 but this was later reduced to 20m.  The ASW 17X was also a single aircraft that was built in 1976 with 19-metre span. One other was modified to 23 metres after production.

==Competition history==
ASW 17s came second in the World Gliding Championships in 1972, third in 1974. George Lee won in 1976 and in 1978 in an ASW 17.  Hans-Werner Grosse broke several world records in his ASW 17 including: the record goal flight at 1,231&nbsp;km in 1974, the triangular distance record 1,063&nbsp;km in 1977  and then again at 1,306.9&nbsp;km, and the 1,250&nbsp;km speed triangle at 133.24&nbsp;km/h in 1980. Karl Striedeck broke another record by a flight of 1,634.7&nbsp;km out and return in 1977 in an ASW 17.
