THE LOW SINK GLIDER
Frans von der Kreek · Technical soaring · 1993
It is shown that the performance of modem gliders can be improved. The use of a large span and a high aspect ratio produces a glider with a good glide ratio and a low sink. Calculations show that a standard glider can be built with a glide ratio of 47 and a sink of 0.45 m/ sec. The low sink glider will fly more hours per day, more days per year. It will open up gliding for more people and in more places. The development of such a glider awould substantially promote the sport.
