Abstract

As part of a joint venture between DASA/Dornier Luftfahrt GmbH and DLR Braunschweig, a laminar wing glove was designed for the Do 228 turboprop aircraft. The glove, covering nearly 50% of half-span, was attached to the right wing of the aircraft. The extensive flight tests, performed in close cooperation between DLR and Dornier, included the evaluation of the laminar properties in the undisturbed glove region and in the propeller slipstream region. The influence of disturbances due to simulated surface imperfections was studied to determine the magnituedes for allowable manufacturing tolerances. A liquid cleaning and de-icing system covering a spanwise region of 1m was tested on the outer part of the glove. In this paper, some of the design aspects of the glove are discussed and the main results of the flight test are presented.
