Will tugs be redundant?
This extract from a full-size forum
Ever heared of winch launches up to 5200 ft (1590m)? in the forum of www.segelflug.de I read the following. It might be of interest for you
(short form translation):
During a glider acrobatic meeting in Fuerstenfeldbruck (Germany/Bavaria), pilots from Bavaria and Austria had the possibility to try a new launch method. Mostly double seaters were launched up to 5200 ft. (1590m).
Acro pilots were enthusiastic after 29 launches, because they could fly their full program out of the winch after only 90 seconds.
This was made possible by the winch manufacturer Tost (Assling, Germany). They supplied a specially modified winch. Karl Hoeck from Friedberg/Germany did the technical calculations and the design of the drum of the winch. This drum had to withstand a pressure of 3 million lb (1400 metric tons) from the 9842 ft (3000m) of Dyneema rope with 0.18 inches diameter (4.5mm).
With headwinds between aprox. 6 and 11 knots (10 - 20 km/h) following altitudes have been reached: ASK 21 and ASK 13 double seated: 5216 ft (1590m) FOX double seated: 4594 ft (1400m) Mue 28 single seated: 3937 ft (1200m)
Well, don't get too excited as they needed a 3000 meter runway to achieve this
