The "Asso" engine was in fact an Isotta Fraschini, not an Alfa:



About the Cant Z1018, I thought that the upper air intake was indeed a feature of the AR 135. You seem well documented, thus I stand corrected.

I found this interesting...

"Alfa-Romeo were involved in many engine-related projects at this time, and they were then an independent company, with fairly sophisticated facilities. The company produced nice 6 cyl and V12 engines, unusually of two-stroke operation with vertical exhaust valves in the heads, and inlet through ports in the cylinder walls, fed by a scavenge blower driven off the front of the crankshaft. The engines shared many common components to keep production costs down, with cylinders of 95mm bore and 130mm stroke, giving a displacement of 5.5 litres and 11.00 litres (338 and 677 cu ins) respectively. Power outputs of 110 hp for the straight-six, and up to 350 hp at 1900 rpm for the V12. Interesting construction features included needle roller big ends, wet liners and composite pistons with stainless-steel crowns. The designer is stated as being a Mr Ricart."

More interesting stuff. Evidently, the 18 cyl Alfa 135 motors were even supplied to the Luftwaffe for use in the FW Condors...

Sorry, the link doesn't work, but search "Alfa Romeo Retrospective", and you'll find it.

I'm still waiting for a solid evidence the engines were actually fitted to FW 200s, but it is said so indeed.

My impression is that only one example of the FW200 was actually flown with the AR 135 motors . Other German aircraft to fly with alfa power were a single JU52 used by ALA Littoria on transalpine routes fitted with 3-AR126rc.34 between 1935-1944. One other German ,although Italian built aircraft to fly was the Dornier Wal and Super Wal which flew with Alfa built Jupiter motors 2 on the Wal and 4 onthe super.( the proto Wal and early production types were Italian built as Germany was forbidden to build such aircraft at the time . The Wal seems to have been fitted with every engine under the sun at various stages)

Do any of these historic planes still exist in museums or anywhere accessable?

A number of AR powered aircraft exist in Italian Museums to this day including Alfa's own museum which displays one record breaking aircraft and an variety of motors and Alfa props.
the following Museums also have a wide range of AR powered and other aircraft on display.
Italian Airforce Museum ,Vigna di Valle, Roma

Museo Aeronautico caproni di Taledo ,Trento

Museo Nazionale Della Scienza e Della Tecnica, Milano,
The caproni Museum certainly has its own website and the Airforce museum should be accessed via the Italian Air Ministry site.
A number of years ago the old Alfa Museum site had a 360 degree QuickTime
virtual tour of the museum . This now seems to have disappeared into the ether but perhaps a way could be found to add thisto the Abb site

Alfa Romeo Jet

I can't read Italian, but what I can see here seems to say Alfa Romeo built a jet engine (or, they had a hand in it somehow)!

(Based on a Dual Overhead Cam 4 no doubt! )

= = = = = = = = = = = = =
http://www.regiamarina.net/arsenals/...jet/jet_it.htm

Tipo - Campini-Caproni
Motori - Alfa Romeo Asso L.121 RC40
Potenza - hp 900

Il prototipo n.1 del Campini - Caproni prevedeva un sistema di propulsione capace di convogliare e comprimere dinamicamente l'aria grazie al moto relativo dell'aereo, successivamente l'aria subiva una seconda compressione ad opera di un compressore assiale a tre stadi accoppiato meccanicamente ad un motore a scoppio aeronautico (un Alfa Romeo Asso L.121 RC40 da 900 Hp), all'uscita del compressore l'aria veniva riscaldata mediante bruciatori esterni e successivamente fatta riespandere attraverso un ugello convergente-divergente a sezione variabile mediante una spina mobile tipo Pelton che generava una spinta pari a 750 kg.

I am afraid that you are qouting from the same incorrect Regia Marine site that attributes the Campini aircrafts engine to Alfa ,when as shown above the ASSO engine is in fact an Isotta-Fraschini motor.

Once again, foiled. I try to add interesting information for everyone, and fall on my face. Thanks for the correction. Darn.

It is a cool plane though.

I would sell my collection of Alfa cars and parts to own an Alfa powered airplane, didn't matter if it flew or not, just owning it gives one bragging rights. If the song of an Alfa spider is sweet, imagine the sound of the Alfa engine in the air...that would be something to hear. I wonder if there is a barn in Italy...

That looks like a marvellous project...I have always looked at the Alfa boxer motor when its been sitting on the workshop floor and said it would make a good aircraft engine.
Any particular modifications needed to make it 'airworthy'? The exhaust looks somewhat un-restricted, just what the boxer prefers. Is it a 1.7L running 40mm IDF's? Where are you located?

That is a picture of Fred DiMatteo with the Benson Gyrocopter. I think that might have been one of his pet projects before he passed away.
