The Conroy Albatross



close enough for a shave!

I wonder if you could gain a few inches by mounting them a bit further aft on the wing. Though eventually the spar would be in the way of course...

Those nacelles come straight off an Andover but the engine could go backwards as it sits mostly over the spar.  There'd be a problem with cg though which is why they are so far forward.

How are these:

I like it.  A few real world worries with a DART however, that proposed drawing puts the blade arcs nearly directly in the path of the pilots-noise, spray, debris and throwing a blade would be of concern    Perhaps mount them a little further back.  Weight is not much of an issue-pretty close to the original engines.  Also worried that the DART might be too much power for such a high thrust line.  Changes in thrust would cause massive trim changes, and engine out performance might overwhelm the flight controls.  Perhaps throw some additional vertical surfaces on the tail like the CL-415.  Another high thrust, high thrust line aircraft, the AN-32, seems to be quite a handfull and has done poorly in engine out scenarios.

But this being WHIF, DARTS on anything look great- go for it.    

All of which are probably why the Avalon proposal mounted the Darts below the wing.

Below the wing does look good.

Hi team,
Here's another artist's rendition from "PBY: The Catalina Flying Boat" by Roscoe Creed of the Avalon Turbo Cat.

Info from that book: "For some Cansos the future may hold a different look and a different sound. Avalon Aviation is considering planes to replace the reciprocating engines of its Cansos with Rolls Royce Dart turboprop engines, creating a "Turbo Cat" that would outperform even the Super Cats. Because the planes are based on land and scoop their loads from fresh water lakes and rivers, none of the corrosion problems attendant on turbine-powered seaplanes which operated on salt water after the war would be likely."

And a 1/144 build of it at another forum I frequent, where I first saw the pic: http://rnzaf.proboards.com/thread/22460/turbine-dart-engined-canso-catalina

A turbine Cat would be a good way to combat lack of P&W/Wright engine spares but - like the unflown Dart Mustang in Australia - perhaps extra (drop?) fuel tanks would be needed? Or would the Cat already have enough capacity to make it feasible? Military variants upgraded? It certainly has my mind working!

Hi,
I'm using the engines from the CL415 to create a turboprop variant of the Catalina.

Likey some but no Catalina in the stash.

I'm sure that can be remedied at Telford??? Maybe with an AIM Dart conversion.

Might do but it's not essential.

That's a great idea ! She was such a robust machine, they'd probably still be bombing fires !

That's a great idea ! She was such a robust machine, they'd probably still be bombing fires !

And at high speed!

There's a proposal to modernise existing Catalinas with turboprops. The website is really not very convincing, light on details and poor CGI images. Can't see this being viable.

Well, you ain't going to do much in the way of increasing speed and it would never be high speed.

Vapourware and the gunship version is particularly absurd.
