HI,

I add here the drawings of the Guidonia I, a three-engined bomber project remained on paper designed by Santangelo,

Is that a fourth engine in the rear fuselage? It looks like it is powering some sort of turbocharger. Seems odd to have the weight of a whole engine to power a single turbo unit for three other engines...

Maybe I am missing something?

It appears to be a version of the german 'HZ-Anlage' device, as fitted to the Henschel Hs 130E,
and Dornier 217P aircraft.
A system operating on the same principle was also used by some Soviet Pe-8/TB-7 aircrasft.
More information to follow shortly.....


cheers,

The increased power at altitude more than compensates for the extra weight...

All modern aircraft have four dimensions: span, length, height and politics.   TSR.2 got the first three right - Sir Sydney Camm

Beautiful, interesting concept that movable wing, the aircraft seems a bit unestable though. Thanks for the link.

The one source that I have to hand, Jonathan Thompson's Italian Civil and Military Aircraft 1930-1945 (Aero, 1963), says that the articulated wing on the Magni-Jona J.6 was fitted with an automatic aileron control system. The design made the airplane unspinnable and thus inherently safe unless the pilot locked the wing.

A J.6S derivative with a fixed wing was offered as a military trainer. The G.M.S. web site says that six were ordered.

Hi,

Caproni Ca.225 was two seat twin engined low-wing
medium bomber,powered by two 1250 hp Isotta-Fraschini
Zeta R.C.42 engines.

The Thompson book says that this was an attack bomber design with 4 x 20-mm cannon and 2 x 12.7-mm machine guns. It was to have a span of 48 ft 6.66 in and a length of 43 ft 5.66 in. Loaded weight was planned to be 12,560 lbs. With the Zeta engines, it was expected to achieve 395 mph.

HI! I need help about these aircraft,
IMAM Ro 45
Piaggio P-111
FIAT BGA
 all were prototypes and ,please, I need the three views and data technical.   I am showing some photos, less than Fiat BGA,
;)

I really know that they are difficult to find, by the little documentation of the Italian airplanes of pre war. Thanks for your time

The BGA was a bomber prototipe with quite average performaces, had 2 x 14 cilinders radial 1000hp fiat engines. 3 turrets with 7,7mm Bredas and a max speed of 400 km/h.This bomber was designed by Ing. Aldo Guglielmetti of the Genio Aeronautico (Aeronautical Engineers) of the Italian AF, hence the designation B.G.A. (Bombardamento Genio Aeronautico). The sole aircraft was built by Fiat's subsidiary CMASA in 1937.

Hello! Reading the story of the twin-engine seaplane Fiat RS.14 I found something about a ground attack aircraft designated Fiat AS.14. From what I understand of this variant had been built a prototype that was also tested at guidonia in 1943. Unfortunately, I didn't discover more information and photograph, someone knows something more? Thanks to all in advance.

All I can provide is a photo (obviously somewhat retouched), I once got via the now defunct
Airwarfare-Forum, source wasn't mentioned unfortuantely.
It takes a long time, before all mistakes are made ...

I'll add another one. Unfortunately, I can't remember the source.
