Cross Pollinated Machines

[elmayerle]

I don't see any absolutely necessary reason for any external changes, part of the reason for the way I described the changes was to maintian the same envelope and such.  The improced arodynamics and materials might allow an increased airflow, which could result in blow-in doors on the inlets if you wanted something to differentiate this variant.

I coukld see some changes to the cannon pod on the JA-37 to go with a gun that at lesat had ammo in common with the rest of the USMC.

The JT8D is a fascinating engine, especially since it wouldn't even have come into existence if RR hadn't been "penny wise and pound (Sterling) foolish".  If anyone wants that story, feel free to ask.

Consider it asked...

From what I've read, the original engine proposed by Boeing for the 727 was a RR engine (Medway or advanced Spey, I think) and one of the vital launch customers was Eastern Airlines.  Now, Eastern apparently had had some real support problems with the engines on their Viscounts and "Capt. Eddie" insisted that the 727 engine either be built in the US or have a major support facility in the US, but RR demurred (presumeably on cost grounds) and Eastern was ready to cancel their order.  In a panic, Boeing turned to P&W who did their now well established two-shaft turbojet to turbofan redesign on the JT8B (J52) to produce the original JT8D and the est is history with P&W, rather than RR, selling a ton of engines.

PS.  The reference for this is the Design Case History of the 727, buplisehd by the AIAA.  A rather fascinating read.

Trying to survive my what-if exile with naught but 2 WW2 aircraft books and a few random kits to satisfy my need for aircraft whatiffery has led to some interesting engine swap ideas.

First off, what about a Westland Whirlwind fitted with handed Rolls-Royce Merlins to replace the unreliable Peregrines? How bout a Commonwealth Boomerang with an R-2800 to replace the R-1830? A Corsair with a Bristol Centaurus? A Henschel 129 with BMW 801s? What about fitting a Stuka with an annular raidator like on a Ju 88?

These are just some of the ideas I could remember off the top of my head. Any input on those is welcomed. Feel free to post you own ideas along these lines. Later.

Easy:   The P-39 should have gotten an intercooled Griffon and 5-blade prop.  It was, after all, designed to be turbosupercharged and intercooled from the beginning.      The Bell Screaming Snake lives!!!! B)

A Heinkel He-112 with a Jumo 213, a I.A.R. 80 with a BMW 801, also a Reggiane 2002 with a BMW 801.

Forgot to add:   He-70 with a DB-605.

How bout a Commonwealth Boomerang with an R-2800 to replace the R-1830?

From what's been published, this was the initial genesis of the CA-15.  At one time, there was a resin kit of the radial-engined variant of the design available.

You mean like a Westland Welkin but with shorter span wings and a non-pressurized cockpit?

Sounds like a good idea to me!

I've been cobbling a Tigercat with a pair of Bristol Centaurus engines for a SEA 46 RN kitty.

Interesting. I've never thought about it, but that would be killer. Maybe using the P-63 as opposed to the P-39, but I'd like to see this idea develop further.

Jon,


If all things work out, one will show up at the McMinneville show in September under the wings of the Spruce Goose in bright royal blue with some white racing stripes on the tail empennage representing some as-of-yet unnamed Russian Team.    Likely the Hasegawa kit will be utilized just to showcase the new kit.

That along with a re-engined Yak-3 from Eduard's Weekend series will complete the Russian Team.   The Yak is planned to be bright yellow.   Cheesy as it is, one is the Blue Belle and the other the Yellow Yak.

Back to the P-39, someone some time back had a link to one of the early Bell P-39 prototypes which was turboed and intercooled.    It looked quite sleek.

Take it one step farther and do the cleanups Kelly Johnson wanted to do but never could 'cause they'd disrupt production lines:

- Replace the radiators and oil coolers with leading edge units along the lines of what the Mosquito had; depending on how badly it'd mess up the plumbing, look at doing something similar with the intercoolers for the turbochargers (why not?  The Griffon would adapt better than the Merline would)
- Longer center nacelle, along the lines of the "Lightning Swordfish" with bubble canopy (either sngel-seat or dual-seat cockpit).
