Ambrosini (Sergio Steffanuti) Pre-War Projects and Prototypes
« on: November 09, 2007, 05:28:12 am »
Hi all,

we all know Sergio Steffanutti for his aircraft S.S.3 and S.S.4, but there must be also a S.S.1 and S.S.2. Do you have some informations about this aircraft/projects? Who knows a short biography of Sergio Steffanutti? ???

Maveric,

Attached is an SS.2 model by Giampaolo Sellitto (and fully deserving the name "Anitra"!).
original: http://www.cmtonline.it/XV_Mostra_Images/0333.JPG

For SS.2 drawing and colour profile, see: Aerofan No.45 1989/5-6 "First Canard of Stefanutti" .

You might also try No.36 1987/4 "The Ambrosini-Stefanutti Family of Aircraft", and
No.51/52 1991/1 "The Second Stefanutti Canard".

Not sure about the SS.1

With all of the talk on the XP-55, I was wondering if anyone had more information on the Ambrossini (SAI) S.S.4? I always thought it was a really nice looking canard fighter.

Also, when I say more info, I mean with regards to any possible existing detail drawings and the like. There is enough info on the net about it's very short lived history. ;)

A few more details from volume 2 of "Dimensione cielo"

Armament was supposed to be 2x20mm and 1x30mm cannons
fuel tanks between pilot and engine and in inner wing panels

The SS.2 motorglider testbeds (there were 2, built at Guidonia in 1935) were powered by a 16CV Keller two cylinder engine.
In 1937, one of the airframes was modified with the addition of a second seat (becoming the SS.3) and a 38 CV C.N.A. engine (initially rated at 26CV). The SS.3 was flown extensively and made cross-country flight between Rome and Milan.
The SS.4 crashed on March 8, 1939. The loss of the aileron was due to vibrations transmitted from the engine, which was bolted directly on the airframe, as well as to defective installation of the said part.
All modern aircraft have four dimensions: span, length, height and politics.   TSR.2 got the first three right - Sir Sydney Camm

I have pics from the S.S.2 and S.S.3, but without other informations. Can anybody tell us more about other Steffanutti aircraft? Was the S.S.4 the last S.S.-design? What´s about the S.S.1...
