DG-200

The Glaser-Dirks DG-200 is a 15 metre class glider built by Glaser-Dirks, now DG Aviation GmbH

Design started in 1976, and it first flew in 1977.

Wingtip extensions to 17 metres were offered in 1978. Later enhancements included a single-piece canopy, a carbon-fibre wing spar and a change in the wing profile. A total of 192 DG-200 were built.

The glider designs

  • a two-piece conventional elevator, with a fixed forward stabilizer and aft-mounted movable elevator.
  • a control stick with a parallelogram linkage to reduce pilot self-indiced acceleration.
  • a schempp-hirth airbrakes, on top surface only
  • a 5"x5" main wheel (drum brake) and a 200x50 tail wheel
  • l'Hottelier connection for the ailerons, airbrakes and elevator (elevator connection is automatic on the DG-202). Flaps connection is automatic.

According to Richard H. Johnson in his Flight Test Evaluation of the DG-200 published in the Soaring Magazine in July 1980:

"The sailplane is a real beauty to behold with its excellent finish and sleek pointed nose. The canopy is exceptionally good, and it provides outstanding forward visibility for the pilot. The cockpit is outstandingly good for moderately sized pilots; I have never flown a sailplane that was more comfortable. I flew several 5 and 6-hour flights in the DG-200 with no discomfort whatsoever.[1]"

The DG-400 motor glider was derived from the DG-202/17C.

It belongs to the same generation as the Rolladen-Schneider LS3, Alexander Schleicher ASW 20, Schempp-Hirth Mini-Nimbus, Eiri-Avion PIK-20 and Glasflügel Mosquito.
