The Flywhale FW650 was a two-seat amphibious sports aircraft designed and built in Germany by Uniplanes GmbH. It is now owned and built by Dornier Seawings under the name DS-2C.
Design and development
The Flywhale, built mainly from carbon fibre composite materials, is a flying boat style amphibian, with a single step hull and sponsons rather than wing tip floats. It accommodates two in side-by-side seating fitted with a single control between both seats. The design also provides room for two people to sleep in the fuselage.[1][2] A large, one-piece canopy hinges forward for access.[3] Behind the seats is a baggage area. The Flywhale has short-legged, tricycle landing gear[1] with mainwheels retracting backwards into the sponsons.[3] It can operate on land and water.[2]
Its high cantilever wings are trapezoidal in plan and can be removed for transport. Its empennage is cruciform, with the horizontal tail part-way up a triangular fin and rudder. A 75 kW (100 hp) Rotax 912 iS flat-four engine is mounted on a necked pylon over the wing in tractor configuration.[1] This originally drove a two blade propeller[1] but more recently a three-bladed one has replaced it.[3] A BRS ballistic parachute is an option.[1]
The Flywhale flew for the first time on 13 September 2013.[1] A second airframe has been completed, including modifications suggested by the flight trials of the first,[1] and this flew in the summer of 2015.[3]
On 19 January 2022, Dornier Seawings announced that they had acquired all intellectual property and production assets of the Flywhale project, which would henceforth by known as the Dornier Seawings DS-2C, alongside the larger Dornier Seastar.[4]
