ATASD description

ATASD is an advanced multi-purpose 4-season amphibious vehicle, designed for passenger and cargo transportation over a wide range of water and ground surfaces.

Founded in 2006, “Interconn Development Ltd.” is an innovative Canadian company, dedicated to developing an entirely new class of light amphibious vehicle. The goal was to build a cost effective, multi-purpose amphibious vehicle that could travel in areas where conventional vehicles could not operate effectively.  From the debris-filled streets of a flooded city to the dangerous ice of a northern lake, from scientific studies in sensitive mudflats to a minesite’s tailings storage facility, from accessing the lakeside cabin to a cost effective alternative to helicopter transport – the ATASD was designed for all these reasons and more.

 

ATASD incorporates the best features of several different types of vehicle:

  • the speed, agility and structure of an airboat
  • the “go anywhere” capability of the hovercraft
  • the stability and weight bearing capacity of a pontoon inflatable boat

 

The result is a rugged, high performance amphibious vehicle with an industry leading class payload capacity,that provides exceptional stability at speeds of up to 90km/hr over water or 120km/hr over snow and ice.

 

Small to medium sized air propelled vehicles have numerous and varied design limitations.  High wave and wind conditions, snow and ice may cause them to become unstable and difficult to control, or render them completely unusable.  The metal or fiberglass hulls of airboats can be damaged by hard surfaces and they require extremely high horsepower motors to move them, due to the friction of the flat bottom hulls. Conventional small hovercraft, although fast under ideal conditions can lose lift and stability in higher waves and have a limited obstruction clearing capacity.  In addition, hovercraft skirt systems are susceptible to damage and can require frequent maintenance. Low temperatures and age make the typical fiberglass construction of light hovercraft brittle and prone to cracking.  This may also allow water leakage into the buoyancy or flotation cores, increasing the weight of the vehicle and making it difficult or impossible to remedy. Although stable with a high payload capacity, Pontoon boats are relatively slow.  

 

The design of the ATASD was meant to overcome these and other issues.  The craft is classified as a “pontoon inflatable boat”, with the underside incorporating a trimaran inflatable pontoon base, with an aluminum tube structure above.  The pontoons provide buoyancy when floating or during slow speed travel on the water, and acts as the base for the skirt to create the friction reducing air cushion.  Also, by virtue of their soft and resilient exterior surface, the pontoons provide a protective role in the event of low speed impacts.  Both the vehicle and the surface impacted are protected from extensive damage as the craft will simply bounce away. The pontoons are also much less likely to harm people in the water, compared to the hard hull structures of most amphibious craft. The craft features a number of control mechanisms that allow the operator to make adjustments to the vehicle “on the fly”, as the payload or environmental conditions change.  Pressure in the pontoons can be increased or decreased manually and the craft can be trimmed for efficient operation via the adjustable rear lift stabilizer, located behind the propulsion fan.

 

This unique design of the ATASD keeps the vehicle weight low at 540kg (1190lbs) for fuel efficiency while operating and for ease of transport between sites, while enabling the vehicle to have an incredible full load buoyancy capacity weight of 3240kg (7143lbs.) and a class leading cargo rated capacity of 850 kg (1874 lbs.)  The open deck plan allows for ease of loading and off-loading, with the deck seating for 6 taking only minutes to install or remove.  The deck can be arranged for passenger seating, cargo or a mixture of both, and has standing room for up to 9 people, plus the pilot.  Included is a removable tent style deck/cabin enclosure which can be heated during fall or winter operation, and a full signal and forward lighting package. Power is provided by a single 2.0L Ford Duratec automotive engine (available in almost any country in the world for parts or service), driving one forward propulsion fan and two coupled lift fans. The lightweight construction of the vehicle not only results in a generous payload capacity, but excellent fuel efficiency and range from the economical 140hp engine.
