Design and development

The Astir is an intermediate glider for recreational flying. It has an unusual bowsprit designed to crumple during a crash landing, preventing damage to the glider structure.[1]

The aircraft is made from aluminum tubing. The wing is covered in Dacron sailcloth and has a Mylar leading edge. Its 10.5 m (34.4 ft) span wing is cable braced. The nose angle is 130° and the aspect ratio is 7.6:1. Unlike many hang glider designs, the Astir comes in one size only with a wide hook-in weight range of 60 to 115 kg (132 to 254 lb). The Astir is certified by DHV as a class 2 glider.[1]

gollark: We could construct a bunch of solar arrays in a lower stellar orbit and do power beaming. We have decent power beaming technology, right?
gollark: Hmm, actually, how many research forks can we make? Do we need to build labs or something?
gollark: Research of what?
gollark: Also, we need to make the giant lasers somehow nonthreatening...
gollark: We should probably ask the other probes first.
