Title: PBY, PBN, OA-10 Catalina and CANSO
Post by: GTX on December 28, 2007, 01:10:11 PM
Hi folks,

I've previously said that the Catalina is one aircraft I don't think I coul d bring myself to whiff, however I'm brave (or silly) enough to see what you could do.  I'll start off with an idea:

New engines - say a RR Griffon as in theSupermarine Seagull:

Of course, one could stick to the real world upgrades and simply give the Cat sharper claws:

Four fixed .50-caliber machine guns bolted to the keel proved lethal to enemy barges and other vessels:

A pair of fixed 20mm cannons mounted in the bow:

That's unfortunate - I've got one of these on the go as we speak   :ar:   However, it keeps getting put on the back burner by other projects  :(  and so far all that I've done is to build the wing. Maybe a candidate for Phoenix Build II  ;)

It'll actually be a Soviet Twin-GST and it'll be quite close to the four engined machine in your post but the tailplane will be at the normal height (and may be left in two sections as on the He-111Z) and the hulls will be connected directly by additional struts. Well, eventually they will - - -  :dum:

Say 4x Turboprops and ASW gear,reprofile the nose,like the Grumman Albaross to contain a search radar and put a MAD in the tail.you could also possibly do away with the waist blister for post war ops,but these are good for more then just gun stations(like in the maritime recon and SAR roles) so keeping them might not be a bad thing.

On that note, didn't the Soviet built ones have the blisters deleted? I suppose you could replace them with somewhat less draggy domes.

Looking at that Supermarine Seagull makes me want to find those 1/24th scale floats from the Trumpeter Spitfire Float Plane kit.  The floats have the right shape and size, all they need are some wings and and engine.

Yes the 1/24 float would work, just needs the forward section shortening a bit though.  Have a look at the photo I have in my Avro Nottingham thread and you'll see what I mean.  I believe Rareplane made a vacuform of it in 1/72 scale,  I've been after one for ages.

I've always wanted to turn a Cat into a flying houseboat.  Throw a couple of dual purpose motorbikes and a zodiac type boat in the back, some bunks and a kitchen. . .  Oh yeah.  I just have this vision of sitting on the wing with a fishing pole out on a big lake someplace.

This was almost exactly how Jacque Cousteaus PBY-6A 'Calypso' was used.  They used to go from location to location with the diving & film gear packed in the Cat, along with a Zoidac.  They used to sleep in it & even had a dinner table in the hull!  Revell did a kit of it, with a zodiac & diver figures & from what I can gather it's hard to get hold of & is the only correct kit of a PBY-6A.

If you have never seen the inside of a PBY Catalina, you are invited to check out the PBY Catalina International Association, Cutaway PBY Project (http://www.pbycia.org/pbycia.nsf/CutawayPBYProject/000a).  This may help clarify what was inside of the actual aircraft since some of you appear to not be aware of the fact that the Catalina was fitted with bunks, kitchen, and other accomodations to allow some of the crew to live aboard the aircraft when it was moored next to the tender.  This was necessary to keep the radios manned as well as to have a damage control party on hand if the aircraft stated to take on water.  The bunks and kitchen accomodations were also necessary for the long patrols which required additional personnel for the long endurance missions and a needed place to allow some of the to sleep while others were on watch.  

As far as desecrating the PBY, I doubt you could do any worse than the guy that bought a war surplus PBY and removed the wings and tail surfaces and turned it into a boat.  There was a picture of this in an old Popular Mechanics or Popular Science that I had at one time.  Now that would really get some second glances at the model contest.  What would you put it under?  Aircraft or Boat?

On that note, didn't the Soviet built ones have the blisters deleted? I suppose you could replace them with somewhat less draggy domes.
The pattern aircraft for the Soviet-built version, the GST - Gidro Samolyet Transportnyi or seaplane transport, were a Consolidated Model 28-1(c/n C-1, NC777, Guba ) and three Model 28-2 (c/n C-2 and two aircraft in "kit" form). The aircraft were a commercial variant of the PBY-1 series and as such never had the side blisters. The 28-2 aircraft were powered by close cowled Wright Cylone R-1820-G3 engines rather than the usual P&W R-1830, the reason for this was that the Soviets were already producing the Cyclone under license as the M-62. The exact number of Soviet produced Model 28s is unknown, most agree that it was less than thirty.

The first aircraft had an interesting history:
http://lend-lease.airforce.ru/english/arti...les/commandeur/ (http://lend-lease.airforce.ru/english/articles/commandeur/)

The Soviets later received 137 of the Naval Aircraft Factory produced PBN-1 Nomad and 48 PBY-6A.
Soviet designation of the Nomad was KM-1, some aircraft were later re-engined with 1,850hp Ash 82FN engines and were redesignated as KM-2.

Removal of the blisters is a common post-war modification.

A number of years ago I was part of a 'consortium' that was going to try to buy one of the Soviet KM-1's as a restoration project.  Unfortunately, the whole deal fell through so we didn't get anything.  Still, it's was the closest I came to being a part (all-be-it a small part) owner of a 'Catalina' - sigh!!!! :( .

Skybarge, proposed cargo mod, the entire blister area became a large sliding hatch.

BTW the Bird Innovator and few other Cats/Cansos actually were used as 'flying motorhomes'.
One semi-popular modification was a pair of dinghies slung under the wings.

Hi all,

Interesting topic that led me to register... I've been working for several months on a concept of turbine-powered PBY inspired by the Basler conversion.
(https://www.whatifmodellers.com/proxy.php?request=http%3A%2F%2Fwww.freylia.net%2Fpf%2Fdesigns%2FPBY-7AT_base_no_marks_s.png&hash=114ce5cc33e0cb80c43df48cbd94f58b876a3f89)

I'm trying to model it digitally but feel free to take a shot if that inspires you :) you'd probably have to redesign the steps a bit, like the Nomad, that's my focus at the moment...

More info and drawings at http://www.freylia.net/pby7at.html

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. :thumbsup:

I'm having the exhaust go up & over the wing

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. :thumbsup:   

I think the DART engines in that profile are actually taken from a Grumman Albatross that was really converted with DARTs in the real world

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.

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.
(https://www.whatifmodellers.com/proxy.php?request=http%3A%2F%2Fi1110.photobucket.com%2Falbums%2Fh455%2Fharrysone%2Fartists_zpsea6049eb.jpg&hash=38d2bb1dbad35020c1b0f37372f48a57860cade7)
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 (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.
