Aeronautica Vittorio Bonomi Designations
The main designer for Bonomi was Dr Ing Camillo Silva - 'Bonomi-Silva' explaining the 'B.S.' system used to designate Bonomi glider and sailplane designs. This 'B.S.' designation system dates to 1929 (although Dr Ing Silva was designing for Bonimi earlier than that. Most Bonimi 'B.S.' designs were assigned popular names as well (my attempt at translating those names comes at the end of this entry).
Most construction was carried out by Aeronautica Lombarda (aka AVIA) - hence the common use of Aeronautica Lombarda BS-28, etc. In 1937, Lombarda finally bought out Aeronautica Vittorio Bonomi.
Prior to becoming part of Aeronautica Lombarda, other designs were built for Bonomi which were not part of the 'B.S.' designation system. Predating the 'B.S.' system were the 1928 Bonomi A and Bonomi B gliders with wire-braced wings - also known as the Bonomi Allievo A and Allievo B. To those, we can add the Allievo C (never seen as plain 'Bonomi C', AFAIK). However, it is possible that there was no relationship whatever between the Bonomi A and Allievo A, etc. [1]
The 1928 Bonomi A and Bonomi B gliders predate that system. But, in 1929, there was the 1929 Bonomi 25 Monoplano which was followed in 1936 by the Bossi-Bonomi Pedaliante human-powered aircraft. Also given here is the Bonomi-Silva Startoplano proposal ... this being more a description than a type name.
There is also mention of Bonomi 2, Bonomi 2bis, and a short-lived Bonomi 2 S (1931; c/n 2; I-AAVN). Despite being designed by Camillo Silva (and concurrent with the B.S.1), the Bonomi 2 and 2bis were not listed as 'B.S.2' or 'B.S.2bis'. I can only assume that the B.S.2 S is related but this airframe lasted only four months. [2]
______________________________________________________
[1] If there is no relationship, we are left pondering the repeated use of Allievo (Student). Kind of an obvious (if unimaginative) name for trainers. Still, might names be connected? Pure *speculation* but perhaps Allievo A relates to the B.S.07 Allievo Italia; Allievo B to the B.S.16 Allievo Bonomi; and Allievo C to the B.S.17 Allievo Cantù - all training gliders dating to 1929.
[2] Golden Years of Aviation also has an odd entry. A 1931 glider registered I-AAYQ is listed as the Bonomi Sconosciuto with c/n 1. But sconosciuto just means 'unknown'. Unless Bonomi was being coe, I presume that Golden Years' original Italian source had listed I-AAYQ as a Bonomi but did not know the exact model of glider.
