Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain sailplanes and soaring flight, relay design, classes and performance from gliding sources, describe training, competition and safety, and distinguish sailplanes from hang gliders, paragliders and powered aircraft.

A high-performance glider designed for soaring flight, using rising air in thermals, ridge lift and mountain waves to stay aloft and travel long distances without an engine, with long slender wings of high aspect ratio, glide ratios up to 70 to 1 in open class designs, and types from training two-seaters such as the Schleicher K 7 to competition sailplanes such as the Schempp-Hirth Ventus-3, historical and national designs such as the Nihon N-70 Cygnus and Nippi NP-100, and motorgliders; sailplanes are flown in sport, competition and record attempts.

What it is for: Soaring flight for sport and competition.

It can be explain design and soaring; relay classes and performance; describe training and competition; distinguish from other gliders.

Distinguishing features

High aspect ratio wings

Unpowered soaring

Competition classes

Launch by tow or winch

What it looks like

A sleek aircraft with very long narrow wings and no engine.

Physical character

best glide ratio: up to about 70:1 ratio - open class

typical wingspan: 15-30 m

distance record: over 3000 km - wave flights

How it is recognised

High-performance unpowered soaring aircraft

Training, club, standard, 15 m, 18 m and open class sailplanes; motorgliders; historical designs

Hang gliders and paragliders are foot-launched; primary gliders are basic trainers; sailplane is the formal term for glider

What the second pass must settle

  • Should motorglider be a separate primary entry?
  • How should gliding sources be linked?
  • The registry entry has merged aliases naming specific types; should they be split off?
