STRUCTURAL DESIGN AND CONSTRUCTION
The SEAWOLF is an aircraft of conventional riveted aluminum construction with particular attention paid to its role as a boat-hulled amphibian. It has a watertight hull designed to operate efficiently in the air as well as in the water. In essence, it is aerodynamically and hydrodynamically efficient. In the sealed hull there are five (5) separate watertight compartments constructed of heavy gauge aluminum skins and bulkheads for strength. This 28-foot (8.6 meter) boat is capable of withstanding countless landings in open water at speeds of 50 to 60 knots.
The strakes on the bottom of the hull add strength, facilitate transition from displacement to the step and enhance maneuverability while step-taxiing. The deep "V" of the hull allows the SEAWOLF to operate effectively in rough water...
...THE HULL CUTS THROUGH WAVES AND CHOP.
The power plant for the SEAWOLF is the proven 6-cylinder AVCO Lycoming engine. This same engine has proven its reliability through many years of use in other general aviation aircraft.
The Lycoming engine drives a 76-inch Hartzell 3-blade, Q-tip constant speed propeller.
This engine/prop combination is mounted on a pylon above the fuselage in a pusher-type configuration. Aside from the inherent efficiency of a pusher-prop, this configuration keeps the propeller away from the abrasive dust and water. It also provides unobstructed airflow over the tail surfaces providing more effective water and ground maneuverability.
The cabin configuration of the SEAWOLF is designed to be adaptable to a multitude of roles. There are approximately three (3) square meters of floor space, including baggage area, behind the pilot's position. Entry to the cabin is through right and left canopy doors and a large cargo door on the right. When the right canopy door and the adjacent cargo door are both open, loading of large objects is easily facilitated through the spacious clear span opening.
Visibility from inside the cabin is excellent in all flight regimes. The mid-wing is aft of the cabin. This design allows unobstructed views from all windows in the cabin even when the aircraft is in a turn. Other configurations include Radar Console Installations, a variety of Air Ambulance arrangements, and of course, a generous amount of room for Cargo and Logistical Support Missions. The interior is designed to be quickly and efficiently changed to meet the full range of mission requirements.
