Reference excerpt

The Schweizer SGS 2-32 is an American two-seat, mid-wing, two or three-place glider built by Schweizer Aircraft of Elmira, New York. The 2-32 was designed to be the highest performance two-place glider available, when it first flew in 1962. The 2-32 has been used as a tourist glider, trainer, cross-country and high-altitude sailplane and has set many US and world records. A total of 87 aircraft were completed.

Design and development The SGS 2-32 was conceived as a mass-produced sailplane of modest performance to act as a step-up from the SGU 2-22 trainer then in common use in North America. After careful examination of the potential market, the company decided to produce a higher performance sailplane with a greater wingspan instead. The 2-32 design was started in 1961 and completed with certification under type certificate G1EA on 19 June 1964. The 2-32 is all-metal, with a semi-monocoque aluminum fuselage and cantilever wings of 57 foot (17.37 m) span. It has top-and-bottom divebrakes and an all-flying stabilator tail. The aircraft seats two or three, with one seat in the front cockpit and a double bench seat in the back suitable for two smaller people of 150 lb (68 kg) each, maximum. The aircraft is often described as a "21⁄2 seater". The ability to carry two passengers, plus its complete and comfortable interior has made the 2-32 a popular aircraft with commercial glider operators for conducting tourist flights. The ability to carry two passengers doubled profitability for rides. The first customer aircraft were delivered in 1964, shortly after certification was completed. The type certificate is currently held by K & L Soaring of Cayuta, New York. K & L Soaring now provides all parts and support for the Schweizer line of sailplanes.

Derivative designs The SGS 2-32 has been the basis of several derivative designs, including:

Operational history As soon as it entered service many pilots realized that this high performance two-place sailplane would be ideal to break many of the two-place records previously set by lower performance gliders. At one time the 2-32 held the two-place speed records over 100 km, 300 km and 500 km courses, as well as many distance, out and return and altitude records in both the men's and women's categories. 2-32s were also flown in the 1964 US Nationals. Some of the records set by pilots flying SGS 2-32s include:

World record two-place out and return flight, 404 miles (654 km), May 23, 1970, Joe Lincoln and Cris Crowl. Lincoln's 2-32, named Cibola, had special longer wings of 67-foot (20 m) span installed that increased performance further. World record two-place speed over 100 km (63 miles) Triangle, 74 mph (120 km/h), 1971, Joe Lincoln. World record two-place feminine absolute altitude 35,463 feet (10,809 m) and altitude gain 24,545 feet (7848 m), 5 March 1975, Babs Nutt. In May 2014 there were still 58 2-32s registered in the USA and one in Canada. In USAF service at the United States Air Force Academy the 2-32 was known as the TG-5.

Aircraft on display The National Soaring Museum has two SGS 2-32s in its collection, N2767Z and N8600R, the prototype. N8600R is currently on loan to and on display at the Evergreen Aviation & Space Museum in McMinnville, Oregon.

Worked examples

Example 1 — a first encounter with Schweizer SGS 2-32

Start with the simplest possible case. Write down what Schweizer SGS 2-32 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Schweizer SGS 2-32 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Schweizer SGS 2-32 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Schweizer SGS 2-32

In research: Schweizer SGS 2-32 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Schweizer SGS 2-32 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Schweizer SGS 2-32 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s United States sailplanes, Aircraft first flown in 1962, Aircraft with fixed bicycle landing gear, so understanding it makes those chapters shorter.
In everyday life: Look for Schweizer SGS 2-32 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
