Re: Ca- 183bis

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!

Re: Ca- 183bis

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.

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

Interesting hybrid fighter project developed direct from the Caproni Campini No. 1 of 1940, with hypothetical coloration at the end of WW2

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.

Hi! My poor guess.

 

[Nicknick]

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.

 

[blackkite]

Hi! Almost same scale.
