Design and development

edit

The Globetrotter was originally named the Schulmeister,[1] reflecting its role as an advanced training glider. It was designed by Ursula Hänle and Walter Stender[2] and is mostly constructed from glass-reinforced plastic (G.R.P.). Student and instructor sit side-by-side under a single piece canopy which opens by sliding forward over the nose. The fuselage has provision for water ballast.[1]

It is a mid- wing monoplane with its wings, which have an Eppler E603 profile, swept forward at 2.5°. Airbrakes extend from the upper wing surfaces only. It has a T-tail and a standard, fixed glider monowheel undercarriage with a tailwheel.[1]

Operational history

edit

The number of Globetrotters built is uncertain. One source says production began in March 1978[1] but another implies the company closed sometime in 1977.[3] There is no hard evidence for the construction of other aircraft after the prototype.

The first prototype Globetrotter was later registered in the United States.[4] No Globetrotters remained on the European civil registers in 2010.[5]
