Aspect ratio (aeronautics) An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing ...
A glider's glide ratio varies with airspeed, but there is a maximum value which is frequently quoted. Glide ratio usually varies little with vehicle loading; a heavier vehicle glides faster, but nearly maintains its glide ratio. [21] Glide ratio (or "finesse") is the cotangent of the downward angle, the glide angle (γ). Alternatively it is ...
Number built. 700. The Schweizer SGS 1-26 is a United States One-Design, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York. [3] The SGS 1-26 enjoyed a very long production run from its first flight in 1954 until 1979, when production was ended. The 1-26 was replaced in production by the Schweizer SGS 1-36 Sprite.
The aspect ratio is 38.8. The fuselage is also lengthened and a larger rudder fitted. The fuselage is also lengthened and a larger rudder fitted. The manufacturer claims this glider has a glide ratio of better than 60:1 at a best glide airspeed of 110 km/h (59 knots ), meaning it can glide over 60 kilometres on course for every 1000 metres of ...
A ratio of 30:1 means that in smooth air a glider can travel forward 30 meters while losing only 1 meter of altitude. Comparing some typical gliders that might be found in the fleet of a gliding club – the Grunau Baby from the 1930s had a glide ratio of just 17:1, the glass-fiber Libelle of the 1960s increased that to 36:1, and modern flapped ...
The SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1][2][5]
The Eagle was designed as an intermediate-level glider. It is made from aluminum tubing, with the mostly double-surface wing covered in Dacron sailcloth and cable braced from a single kingpost. Its nose angle is 122°. [1] [2] The models are each named for their rough wing area in square feet. The Eagle was certified to HGMA and DHV standards ...
FAI Ultralight class sailplane. Type of aircraft. National origin. Czech Republic. Manufacturer. TeST. The TeST TST-10 Atlas is a single-seat, standard class sailplane, with a 15 m (49 ft 3 in) wingspan, manufactured by TeST Gliders in The Czech Republic. It is available both as a pure glider (TST-10) and self-launching glider (TST-10M).
