Description A seaplane with canard configuration (horizontal stabilizer in front). You could say it's an 'alternate' 1920's where the 'traditional' tailplane configuration never became popular with aircraft design. I guess it's sci-fi in this respect? Ironically the canard is THE original configuration. Check out Wright brother's Flyer that achieved the first powered flight in 1903. The more traditional tailplane configuration that most of us are familiar with now never truly became popular until 1909 with Bleriot's airplane (first plane to cross the English Channel). Almost every single plane since then had been following this trend, and for a good reason. Having the horizontal stabilizer at the rear increases stability, which is a problem in early aircraft designs. However, canards provide better efficiency and agility, and a well-designed plane with canards is still stable enough to be controllable without a computer. Recently canard planes seem to have made a come-back, especially in European fighters (Typhoon, Rafale, Gripen). Guess with modern computers, aerodynamic stability is no longer an issue.

A nice and solid looking design concept.

Very "Porco Rosso". And an interesting idea, from an engineering viewpoint.

Burt Rutan pioneered (and patented) a system where the canard stalled before the main wing, thereby dropping the nose and preventing the main wing from stalling. Sounds like a safe idea to me...

I was about to ask where the rudder was on this craft but I notice that it's along the wing, outboard of the pontoon. Twin rudders! Cool!

Maybe you can tell me; 'coz I haven't been able to figure it out or find any resources about it. What are the advantages and disadvantages of twin rudders? Or even triple rudders (like those on the Constellation) for that matter?

Good question. The first answer that comes to mind is redundancy, but I'm sure there's more to it. Vertical stabilizers are located at the rear, so they have to deal with air flow disturbances caused by the rest of the aircraft in front. So my guess is the advantages/disadvantages of multiple vertical stabilizers depends on the design of the rest of the aircraft. You may want to place them in a more energetic part of the air flow created by the wing/fuselage for more efficiency. Or you may want to place them away from a more unstable and hence dangerous part of the streamline. There're probably other more creative reasons too. I've heard that A10's twin vertical stabilizers can be used to shield infrared signature of engine exhaust from heat-seeking missiles approaching from the sides. Go figure.

wow... i thought it was just me that knew this crazy stuff about plane wing configuerations..
good pic btw.. it looks like a SUB with wings bolted on as an afterthought

Doesn't look like a functional design, although still very beautiful.

A lot of things are possible with fly-by-wire technology.
