  • Tigerfish - an Idea That Floats, and Flies
    Posted by Graham Warwick 2:23 PM on Feb 26, 2010

    I have a soft spot for aircraft that operate from water - floatplanes, seaplanes, flying boats. So my attention was caught by a release from Quasar Aerospace Industries saying it had formed a joint venture with Australia's Tigerfish Aviation to develop that company's Retractable Amphibious Pontoon Technology (RAPT) - retractable floats designed to be fitted, or retrofitted, to almost any aircraft, avoiding the full drag penalty of fixed floats

    Based in Norwood, South Australia, Tigerfish has been working on the RAPT concept since the late 1990s, doing design studies and small-scale wind tunnel and water channel tests. It has studied potential applications ranging from the Gippsland GA8 to the C-130 Hercules, and flew a radio-control scale-model Cessna Caravan in 2007 to demonstrate the retracting-float principle.

    The Quasar deal looks like a breakthrough. The two companies have formed a company - Tigerfish Aviation USA, 70% owned by Quasar - to oversee development and certification of the RATP. Quasar says four engineering firms, one German and three US, have received a request for proposals to do the work, which it estimates will cost $5 million. A Dornier 228NG twin-turboprop has been selected as the proof-of-concept aircraft for the program.

    Who is Quasar? That's a little difficult to say. CEO Dean Bradley, who described himself to me as a "deal junkie", says Quasar is intended to be the holding company for a wide range of aviation interests. The company already owns a flight school in Florida, Atlantic Aviation, and says it has other subsidiaries working on a four-seat trainer, a very-light jet and a new piston aero-engine - but these ventures are still shrouded in confidentiality.

    Quasar announced in November it had arranged $350 million in funding to finance its ambitious acquition plans. That deal has still to close, but Bradley says the $5 million is in place to fund the Tigerfish program.

    Meanwhile, my colleague Bill Sweetman reminds me that the concept of a retractable float is not new, and points me to the unfortunate Blackburn B20, a flying boat with a deployable hull, which first flew in 1940 - and crashed on its first high-speed run, possibly because of aileron failure caused by flutter. I wish Tigerfish better luck.
