Well due to the fact that the He-112 is already in use in the Chinese Air Force, a Chinese aircraft manufacturer get the order
to investigate this model and modify it if necessary. The result is the Che-112 from Chengdu Aircraft Industries Ltd. .
The Che-112 is basically a "normal" He-112, but it now has instead of a V-engine a radial engine and some changing of the dimensions.

The carrier version is of course equipped with folding wing tips and one tail hook.

The weight looks rather too low, given that the R-2600 you're using for an engine weighs 930 kg by itself. Given that weight, I'd expect the light weight of your plane to be closer to 3000-3200 kg.

You'll also want to remove the projection from the propellor spinner that looks like a cannon muzzle, the R-2600 is not suited to a motor-cannon.

Would a 1,700hp radial fit very well in an He-112 fuselage?

A 1700hp radial wouldn't fit AT ALL in an He-112 fuselage. However, judging by the picture, there's not much left of the He-112's fuselage, the He-112 ancestry is probably in the wings, cockpit glazing, and tail assembly, not in the fuselage.

No problem with changing the weight !!

As i mentioned, there was some changing of the dimensions.

It's quite an optimistic aircraft for China to be developing.

I think a He-112 with a Nakajima Sakae is more reasonable. The engine would actually fit, doesn't weigh too much more, provides a useful increase in power, and should be reasonably available from Japan. I can't see 670km/h though.

Sure it's optimistic, but not unattainable.

May be the R-2600-9-2 radial piston (same as used in the B-25) was too optimistic. But i thought this engine is still in service and could work (i'm no specialist in aircraft manufacturing ).

What about the R-1830-21 (1200 hp) engine (still in use at the SF-202) ?

The max. Speed is without any weapon and too much fuel !! It's the speed of a nearly empty aircraft

I'd prefer to see performance figures represent actual combat performance capabilities rather than inflated stats...

Nope.

A 1200 hp radial engined He-112 derivative probably won't have better performance than the 1000-hp DB-600 powered He-112s that China already has.

Another possibility is the GWM L-1500 (1482hp). But i have no datas for this engine. May be Vuk has some.

@Brock:
It also have a "normal" speed

Speaking of modyfing the He-112, this plane might be of interest:

Quoted

Last plane is a heavy fighter as CAC tries to get back into the fighter business after losing the fighter contract to Australian Aviation. CAC teamed up with Heinkel (secretly) to design this new plane. The wing is very similar to that of the He-112.



CAC-11 Strix (based on OTL Weiss WM-23 Ezustnyil )

Power: Pratt & Witney 1,350 hp R-1830 Twin Wasp

Armament: Four 7.62/0.3in machine guns

Size: Wingspan - 34ft 9 in
Length - 34ft
Wing area - 250sq ft

Weight: Empty - 5500lb
Max take-off - 9000lb

Performance: Max speed - 340mph
Ceiling - 29,000ft
Range - 900 miles
Climb - 3200ft per minute

Okay, i must change the dimensions just a little bit, but if we compare the technical details (power, speed, ceiling) we see, that with the GWM L-1500 (1482 hp) (the CAC-11 has a P&W with 1
350 hp) the stats are okay.

So if it's okay i will modify the dimensions to:

Length: 10,8 m
Wingspan: 10,6 m

max. Speed on ground level: 495 km/h
max. Speed in 5000m: 540 km/h
cruise speed in 5000m: 480 km/h

You can use the Ash-82 stats or develop a Ash-82FN clone and you have a 1700 Hp engine that fits btw why use the wooden VM-23 as a base?

Or see if Roo has developed the Homare

Because i'm not a specialist in aviation i have one question:

Why we have problems with a R-2600-9-2 , but an Ash-82 (or a clone of it) will fit ? Both engines have 1700hp

Nearly the same weight, both have ~900kg, okay the Ash-82 is a little bit lighter (890kg <=> 930kg) ! The Ash-82 is longer (2,01m <=> 1,58m ). Same number of cylinder, nearly same displacement.

Source: wikipedia

The Ash-82 is smaller and lighter than the R-2600, but probably still too big and heavy for the He-112.

If you can fit the R-1830 you can fit the Ash-82 since its mount is far snugger than the US engine, the weight might be a problem, not also that the Lagg-3 accepted the Ash-82 & 82FN, So an all metal Chinese He-112 should be able to accept the Ash-82.

You say the Ash-82 is smaller and lighter than the R-2600, but wikipedia says the R-2600 is smaller Okay the Ash-82 is 40kg lighter

It's sure a all metal aircraft.

We have to find a solution.

As Vuk said, the Lagg-3 accepted an Ash-82 and with the modified stats i mentioned above, the Che-112 is bigger than the Lagg-3.

You are confusing the size of the engine with the complete mount
