Now, I wonder... where can a guy, just a regular Joe, go to get more information on this concept? Perhaps even good three view drawings?

Hmmm...

Unidentified Supersonic Seaplane

I just stumbled across three files about a six engine supersonic seaplane study on the NTRS that looks like nothing I've ever seen. Any takers on identifying it.

Re: Unidentified Supersonic Seaplane

Interesting design! But there doesn't seem to be any hint of a manufacturer behind the design. Possibly just a generic design emanating from NACA. This being said, the model is supposed to represent an aircraft to be powered by "six Orenda
Iroquois PS-15 turbojet engines" (see p.4), and that points to a Canadian more than American project, doesn't it?

Avro Canada project?

Re: Unidentified Supersonic Seaplane

I've added links to the other two documents to the OP. Due to the size (19 & 48mb) and the fact that I'm on dial-up I've not looked at either of these yet.

It's the Martin Model 329.
