Which US engines would you use to power the Ju 88? ???

The Allison V-1710 with the annular radiator or a radial?

If going radial, I'd suggest the P&W R-1535 for pre-/early production followed by the R-1830 for later production.


(Merlins, the only other really viable inline option in the pre-war era, wouldn't be on the radar in the US at this time.)

Hadn't thought that far.  Maybe Allison V-1710s as suggested for the inline versions or R-2600s for the radial versions.

The R-2600s offer a significant increase in power over the Jumos but this is somewhat offset by a significant increase in weight (from my very rough mental guesstimates) & the diameter seems to be significantly greater, too.

I suggested the Wasps because their diameter seems to be not overly dissimilar to the Jumo 211 & they're in the same power output range, & their weights kinda fit the rough Jumo+cooling guesstimate I made.

The Allisons are a fairly good fit; smaller frontal area, only about 50kg/105lb heavier & up to 500hp/365kW more power, each - the length could be a bit of an issue, though, as they're longer by about 42cm/16.5".



Sorry, waffling. :-[

As mentioned, I was only looking at the R-2600 as a replacement for the BMW 801 powered variants, not the Jumo powered variants.  BTW, here is a quick comparison of radial engines"


BMW 801
Type: 14-cylinder two-row air-cooled radial engine
Length: 2,006 mm (79 in)
Diameter: 1,290 mm (51 in)
Dry weight: 1,012 kg (2,231 lb)
Power output: 1,560 PS (1,539 hp, 1,147 kW) at 2,700 rpm for takeoff at sea level
[Later versions up to 2,000 PS (1,973 hp, 1,471 kW)]
Power-to-weight ratio: 1.13 kW/kg (0.69 hp/lb)
R-2600
Type: 14-cylinder two-row air-cooled radial engine
Length: 62.06 in (1,576 mm)
Diameter: 55 in (1,397 mm)
Dry weight: 2,045 lb (930 kg
1,750 hp (1,305 kW) at 2,600 rpm at 3,200 ft (975 m) military power
1,450 hp (1,080 kW) at 2,600 rpm at 15,000 ft (4,575 m) military power
Power-to-weight ratio: 0.86 hp/lb (1.40 kW/kg))
R-1830
Type: 14-cylinder two-row air-cooled radial engine
Length: 59.06 in (1,500 mm)
Diameter: 48.03 in (1,220 mm)
Dry weight: 1,250 lb (567 kg)
1,200 hp (895 kW) at 2,700 rpm for takeoff
700 hp (522 kW) at 2,325 rpm cruise power at 13,120 ft (4,000 m)
Power-to-weight ratio: 0.96 hp/lb (1.58 kW/kg)

Vehicle a 1980 concept by Czech architect Jan Kaplicky for an air-portable vacation home.
Kaplicky had an interesting career, and up until his death he made the drawings of his concepts
with standard drafting tools, no CADD.







The book Drawings accompanied a show of his drawings back in 2015 at the London Architectural Association.
I have a copy and it's stunning.

Indeed. In Kaplický's exhibit illustrations, even where familiar things are included - like a Hughes helicopter - it still looks like sci-fi!

Cool stuff but gotta love Jon's Ju 388 vacation home  ;D

Has this config ever existed in RW?  I mean squared tail with early nose and canopy.

This can be a scaleorama project with a 1/72 Ju-88 and a 1/48 Ju-87

No need to re-scale...some Ju88s did carry twin 37mm cannon:



I'm not sure if one can get a kit or a conversion of it though.
