Commercial Missions

Able to operate on water or land, the Seastar provides unforeseen flight opportunities for commercial operators. Its “flying boat” design enables to land in sea states with up to two-foot waves (demonstrated but not limiting). Moreover, due to the Seastar’s ability of using a ramp to transition between water and land, passengers may board the aircraft without the need of an airport. Direct operating costs are significantly lower compared with aircraft of its size, due to higher cruise speeds and significantly reduced maintenance cost.

Governmental and Special Missions

The Seastar is the ideal aircraft for operations such as coastal surveillance, patrolling, environmental control, fisheries protection, emergency medical services, search and rescue, drug interdiction and disaster relief, to name a few. Used as a multi-role platform the Seastar is able to perform the combined operational tasks usually requiring both air and seaborne assets. This ability to combine asset tasking will produce faster response times, increase operational flexibility and reduce costs in comparison with the use of existing fixed wing, helicopter and seaborne assets.

Corporate Missions

With comfortable seating for up to twelve passengers and low direct operating cost (DOC), the Seastar is the best choice for fast transportation and corporate mobility on water and land. It can be configured to fulfil a wide range of special missions.

Advantages

The engineering principles of the Seastar lead to a series of advantages compared to conventionally designed aircraft. The areas of particular improvement are performance, safety and operating economics when compared to helicopter or conventional aircraft.

Performance

With a maximum cruise speed of 180 KTAS, the Seastar is 40 KTAS faster than its nearest competitor. The powerful Pratt & Whitney PT6A-135A turboprop engines provide Seastar with 1,300 horsepower flat-rated, allowing the aircraft to become airborne quickly with take-off runs of only 2,244ft/684m on land and 3,445ft/1,050m on water (obstacle 35ft/10,67m, MTOW).

Operating Economics

In terms of direct operating costs, the Seastar is the most economical aircraft in its class. The all-composite, corrosion-free boat hull significantly reduces maintenance cost compared to other aircraft. Due to its manufacturing quality and durability, the residual value is poised to be significantly higher than that of metal aircraft.

Safety

A main design principle of the Seastar is related to enhanced safety. The aircraft is certified by both EASA and FAA. Equipped with two proven and highly reliable Pratt & Whitney PT6A-135A turboprop engines in tandem configuration, which eliminates the possibility of asymmetric thrust in the event of an engine failure. It offers twin-engine reliability with docile single-engine handling.

structure with a three spar fail-safe design. The same holds for the fuselage: the rigid structure and integrated design results in long structural life and high damage tolerance properties. The “boat hull” is able to cope with rough sea conditions. The Seastar design results in docile flying characteristics with a stall speed of only 66 KCAS in the landing configuration (land).

Durability

The Seastar was designed in Germany and strictly adheres to Dornier’s high- quality standards. Its all-composite hull is resistant to extreme environments, even when the aircraft is left in saltwater areas. It is resistant and far more durable than conventional aircraft, especially if made from aluminium. The Seastar’s all-composite airframe maintenance concept is “On Condition”. The entire aircraft is certified for 30,000 flying hours after which a special inspection is required for extension.

Maintainability / Versatility

Conventionally designed aircraft and helicopters require a high level of time-consuming maintenance. The Seastar was systematically designed to reduce complexity and allows operators to focus on missions. The Seastar is durable in an economical sense, by combining the advantages of performance, efficiency and safety.

Production

Practical and Safe

The composite airframe is constructed of 5 types of glass fibers and 3 types of carbon fibers, layered carefully with calculated thickness and formation.

The material grants the advantage of visual inspection; and the corrosion-resistant structure is carefully incorporated with aluminum mesh to reduce static charging and lightening protection.

Highest Quality Craftsmanship

Dornier Seawings employs in-house composite production and quality inspection of the major airframe components including the wings and fuselage.

The components are elegantly designed, carefully calculated, and precisely manufactured with up to 25 layers of composite materials.
