The Dornier Do 228 101 is distinguished by some modifications from the standard specification.
The Dornier DO 228-101 (registration D-CODE), an airborne universal research platform, is used by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) for an exceptionally wide range of experiments. For instance, it is used to conduct laminar flow investigations of aerofoil profiles, test optical sensors that are capable of creating a synthetic outside view and flight guidance systems, and conduct remote sensing missions.
The following modifications differentiate the Dornier Do 228-101 from the standard model:
Missions - research focus
The Dornier 228-101 "D-CODE" is used for the following experiments:
Laminar flow investigations of aerofoil profiles
These investigations aim to prevent the laminar-turbulent transition, which can be caused by insects, icing or other contaminations of the nose of the aerofoil.
Turbulent flow around an aerofoil is characterised by eddies and crossflow, which increase the aerofoil's viscous drag, causing an increase in fuel consumption. DLR scientists are developing ways to keep the flow around an aerofoil profile laminar for as long as possible, preventing the occurrence of eddies and crossflow, in order to minimise viscous drag.
Enhanced orientation - creating a synthetic outside view using radar and infrared sensors
The Do 228-101 is used to test radar and infrared sensors in order to improve the flow of traffic in the air and on the ground. These sensors are meant to compensate for reduced visibility, for example due to rain, snow or ice. The synthetic outside view system can display digital runways on cockpit monitors and it can visualise flight paths and taxi routes. This system is aimed at providing pilots at complex airports with enhanced orientation capabilities and improving their view of the traffic around them.
Remote sensing with the High Resolution Stereo Camera (HRSC)
DLR also uses the Dornier 228-101 universal research aircraft for remote sensing. It is especially well suited for camera flights, such as those carrying the HRSC (High Resolution Stereo Camera), operated by DLR and also used in space missions.
