Design and development

The airship has an aluminium gondola with room for a pilot and a passenger,[1] except the smaller DP-50 which only has room for a pilot.[2] The four variants (DP60, DP70, DP80 and DP90) have envelope sizes from 1700m³ to 2548m³.[1] The DP-50, DP-60 and DP-70 use a 570cc Konig Model SD engine, with a Konig 3-bladed propeller in a shroud as standard.[2] The DP80 and DP90 use a Rotax 582UL piston engine with a three-bladed pusher propeller in a shroud. The Konig can also be used on the larger airships and the Rotax on the DP-60 and DP-70 as an option.[1] Each airship is also fitted with two propane tanks for the buoyancy burners.[1]
