I actually created that forum post myself. XD

As I promised you Blacklynx,

I will search on a more Info about it,but that needs time.
 
Re: Ca- 183bis

I greatly appreciate it and will be looking forward to any information.
 
Re: Ca- 183bis

What I am most interested in is what skybolt refers to as the 'Caproni Technical Descriptions Brochure'.

Everything is known on the 183 will be in ISP, IF it appears early next year.

Wow,a good news my dear Skybolt.

Is there a realistic chance of this? I'm sure I'm not the only one who would be very glad if this long anticipated book finally came out! :)

I'll post complete data later, for now I only say that the gun on the engine was a 20 mm one like the other four, not a 30 mm. Lot of legends on this project, as you see. BTW, I'm not convinced that the DB-605 transmission shaft could even house a 30 mm caliber gun...

————————————————————————————-
Most motor-cannons operate completely outside the engine, ergo no need to worry about compatibility with the crankshaft. They will not fire through the middle of the crankshaft. Often they nestle into the V between cylinder banks.

Instead, most motor-cannons only fire through the propeller speed reduction unit. Since the PSRU offsets the propeller from the crankshaft, the cannon barrel has no need to penetrate the crankcase. . Since the contra-rotating propellers needed a completely new PSRU it would be easy to specify a 30 or 37mm cannon - at the start of the project - and design the new PSRU around the larger cannon.

Greetings

In short: this plane is a motorjet fighter serived from an earlier Campini N.1. I knew 183 existed for some time, but I only recently discovered that it was, as some sources claim, 80% finished at some point in late 1944 or early 1945. The prototype was then destroyed in allied bombardment and was forgotten.

I searched several sites for pictures or any evidence the partial prototype existed, but the only evidence I managed to find is a blueprint of some sort.

Question: do pictures of the prototype exist?

Kind regards :)

This was also my guess, it makes totally sens to place the water coolers behind the compressor, so that the cooling heat can be used for generating thrust. The intercoolers are placed in front of the compressor where the temperature of the air flow is cooler.

A couple of years ago I did some calculations and came to the conclusion, that a "mild thermojet" with low compression ratio and heat only from the cooling/charging+ exhaust system can be an efficient approach for an high altitude plane. Of course, most of the power would come from the propellers.
 
I guess this is quite exact.

The propulsive sheam in #59 indicates, that there might have been a differential which drives the superchagers with increasingly speed with increased torque. Such drives have been used in some truck engines long time ago, it would make sense because it enables a variable super charger drive.
 
Hi! Almost same scale.

certainly experienced with the project of the high-altitude fighter Ca,183 BIS. Designed by Caproni technicians, it was an all-metal monoplane aircraft with a retractable carriage and fixed tail wheel.

13.53 m long, 4.10m high, it is equipped with a low wing with a large aspect ratio with a trapezoidal shape and rounded ends.

The wing was clearly oversized so that a wingspan of 21m was combined with a wing area of 42.50sqm.

Fuel tanks were housed in the capable wings. The aircraft was designed as a single-seat daytime aircraft and was armed with five 20mm cannons four of which are in the wings, and one in the engine firing through the propeller shaft.

The wing guns were equipped with 800 rounds, while the cannon-engine had 150 rounds in the magazine.

The fuselage of the Ca.183 BIS was intended to be built in two sectors.

The front one contained the Daimler Benz 605 engine, pressurized driver's cab, a fuel tank and the FIAT A 30 auxiliary engine.

At the rear of the fuselage was the jet engine.

The Ca.183 was also equipped with two compressors, the first to restore the supply pressure up to 15000m, while the second to restore the FIAT engine feeding pressure from 3000 to 5800m.

The fighter, moreover, was equipped with a double burner duct or perhaps, better to say, a single burner composed of two concentric ducts, one internal and one external.

The outer tube served as a ignition and fuel injection system was convinced.

The Caproni 183 bis, like the RE 2005R, would also have used the burner system only during combat, in order to limit consumption.

The propulsion system, without aftercombustion, would have allowed the maximum speed of 740km/h at 16000m, 660km/h at 11300m, 460km/h at 2100m and 420km/h at zero altitude.

With the afterburner running, however, the expected top speed was 780/820km/h at 16000m.

The aircraft, which had a practical ceiling of 17600m and a theoretical 10000m in 10'20" and at 15000m in 34'34".

The autonomy was remarkable, for an aircraft that required large quantities of fuel.

The latter was expected to take 2000km. Unfortunately, even the Ca.183 bis remained only an idea sketched on paper.
