S.A.I.M.A.N. -- Società Anonima Industrie Meccaniche Aeronautiche Navali

The Società Anonima Industrie Meccaniche Aeronautiche Navali (the Naval Aviation Mechanical Industries Limited Company) was formed at Lido di Roma in 1934.* Part of the Caproni group, S.A.I.M.A.N. (also rendered as SAIMAN, or Saiman) was initially a repair and maintenance facility.

There are some puzzles about SAIMAN production. According to some sources, the first aircraft produced was the 1936 SAIMAN C.4, designed by Ing. E. Cambilargiu. The C.4 was a rally aircraft developed specifically for the Avioraduno Sahariano (Saharan Circuit). The C.4 was a one-off and it seems unlikely that Cambilargiu designed any other aircraft for SAIMAN (I'm attaching the beginnings of a separate Cambilargiu list below the SAIMAN list).

Oft-repeated online references claim SAIMAN's founding to have been in 1929 with aircraft construction beginning "in 1932 with an experimental monoplane, designated C.10, which had a variable-incidence wing." SIRIS also list a "Saiman C.10". There was a Cambilargiu C-10 but that was an incompleted 1924 glider project. Was this 'Saiman C.10' a separate design and, if so, by whom?

SAIMAN's CEO (L'amministratore delegato) was Ing. Guido Sacerdote but there is no indication that this engineer was a design role. The Chief Designer for SAIMAN was Ing Mario Bottini* who had a hand in all other SAIMAN aircraft designs. Bottini had come from Gabardini where he had designed the Lictor series of low-winged light monoplanes (which, it has been claimed, were an influence upon the SAIMAN 202).

SAIMAN Aircraft Designation Style

The first SAIMAN aircraft designs were designated with their designer's initials:

C. --- For designer, Ing. Emanuele Cambilargiu

L.B. - For designers Carlo Francesco 'Francis' Lombardi and Mario Bottini

The second series of SAIMAN aircraft designations were numerical only, beginning with 200. That sequence continues at least to the SAIMAN 208. Then, for no obvious reason, the SAIMAN sequence jumps to 303. It is tempting to suggest that the type designation SAIMAN 303 seemed like a neat follow-on to the SAIMAN 202 it was to replace. But that is purely speculative.

The SAIMAN V.A.L. (for Volo l'Assaltatore Leggero) may have been otherwise undesignated or this light attack aircraft's numerical designation may simply have been lost in time.

Designations are sometimes assigned a prefix, eg: SAIMAN S.202 or even SAIMAN C.202. It is doubtful that this was an official designation style. However, suffixes were applied -- especially to the SAIMAN 202 series. These include:

R -- Raduno (Rally)
RL - Raduno Littorio
I -- [?? Iniziale, Inizio ??] ie: I serie**
M -- Militari (military version)

Other suffixes include 'bis' and 'B'. Presumably, both refer to second variants.

_______________

* Mario Bottini is also listed as the head of SAIMAN's research department. Ing. Bottini began with Giuseppe Gabardini but the latter was not popular among Fascist decision-makers.

**
-- NB: May simply refer to Alfa-Romeo 110 I engine

Ing. Emanuele Cambilargiu: B. 26 Nov 1894, Brescia, D. died 02 March 1973, Bologna (sometime the name is shown as Cambilargiù)

Emanuele Cambilargiu served as a Corpo Aeronautico Militare reconnaissance pilot in WWI. Despite anti-Fascist leanings, Cambilargiu remained in the Regia Aeronautica, eventually rising to the rank of maggior generale. But Cambilargiu also completed his engineering degree and as a G.A.r.i. (Genio Aeronautico Ruolo Ingegneri), he became a professor of aerodynamics at the University of Pavia.

Best known for papers on aerodynamic theory, Cambilargiu also helped produce student designs for experimental gliders. The first was the Goliardia (Student Spirit), the second glider design was the ASUP (after the acronym of the student association at Pavia).*

In 1925, Ing. Cambilargiu formed Costruzioni Aeronautiche Italiane in Milan with pilot Amedeo Folz (who also financed the new firm). Designations applied were 'CF' for Cambilargiu-Folz.** The CF-1 lightplane and its CF-2 derivative seem to have been CAI's sole products.

Cambilargiu's C.4 monoplane tourer was built as a one-off by SAIMAN in 1936. This 4-seater won the II° Avioraduno Sahariano in the Spring of 1936 but no production followed. Some sources say that, back in 1932, SAIMAN had earlier produced the C.10 - an experimental monoplane with a variable-incidence wing. If true and a Cambilargiu design, the designation conflicts with the earlier Cambilargiu C-10 glider project.

Emanuele Cambilargiu left for Brazil in 1947 but moved to the dryer climate of Argentina for health reasons. In 1951, Cambilargiu settled in Uruguay and teaching at the Facultad de Ingeniería de Montevideo (becoming Director of the Laboratorio de Aerodinámica). Cambilargiu returned to Italy in 1969.

_______________________

* Most Italian student associations were suppressed after the establishment in 1927 of the Gruppi Universitari Fascisti (GUF).

** Some sources list the company name as 'Cambilargiu-Folz' (perhaps because the Costruzioni Aeronautiche Italiane name was so generic?).

Excellent work as usual my dear Apophenia,


and I can add;


L.B.1 was also tourist light aircraft prototype,but no more details are known.
