Claude Dornier Sea Star
Preproduction Sea Star CD2
Flying Boat, Germany, 1986.
Dornier succcessfully test flew preproduction Sea Star CD2 with technical modifications in 1988.
Modifications included –
Increase in wing area from 28.5 to 30.5 sq.m.
Replacement of the original P&WC PT6A-112 engines with –13S models of 650 hp at takeoff and 500 hp at cruise. This led to a 400 kg gain in takeoff weight, better climb rate, and up o 11 hrs in single engine (600 hp) mode.
Addition of a small keel on the underside of the hull, resulting in greater stability and reduced takeoff and landing speeds.
Modifications to the upper strut shrouds and air intakes, allowing an increase in empty weight, from 2.6 to 2.8t, and rise in payload capacity, from 1.6 to 1.8 t.
