This is a picture of the type under construction. The fuselage was wood sheeted not unlike a lot of German biplanes from the late WWII preiod (such as Albatros, Pfalz and LFG Roland types).

File: VL_Viima_II-cutaway.jpg (299.2 KB)

I think that I will write about the second aircraft that I wanted to talk about.

The VL Viima was a biplane trainer produced in Finland by the State Aircraft factory or Valtion lentokonetehdas (VL for short). The type itself is not inherently special, resembling much of the type's contemporaries (such as the de Havilland DH.82 Tiger Moth, Stampe et Vertongen SV.4, Polikarpov Po-2, Bücker Bü 131 Jungmann, Heinkel He 72 Kadett, Focke-Wulf Fw 44 Stieglitz, etc.), but what is so interesting about it is its long service life.

The type first flew in 1936 in its initial variant, of which two prototypes were produced. They were both of the same design, featuring a tubular steel fuselage, unequal span wings of plywood construction with a positive stagger, braced with N struts (forward facing on the interplane struts and "reversed" on the cabane struts, with cross-rigging as is typical with most period types, ailerons positioned on both top and bottom wings (which was, in some ways, unique) and an elevator surface featuring a Flettner Flap (again, somewhat unique among other trainers).

This was all retained between both the Viima I and the production model (Viima II) variants, but the Viima II had a revised fuselage, new airfoil and redesigned fuel system making the aircraft, lighter and more well balanced in flight.

Both of these aircraft featured a Siemens-Halske SH14A 7 cylinder radial engine, the same engine used on the Bücker Bü 133 Jungmeister (C and D variant, the most numerous ones of this type), Heinkel He 72 Kadett, Focke-Wulf Fw 44 Stieglitz and the vast majority of early German helicopters, but a later variant, the Viima IIB had a de Havilland Gipsy Major inline 4 cylinder engine, as was used on the de Havilland DH.82 Tiger Moth, de Havilland Canada DHC-1 Chipmunk, Miles M.14 Magister and Stampe et Vertongen SV.4, among many other types. It is unknown if the IIB was produced this way or if it was a conversion (and how many were produced/converted).

The VL Viima does not a have certain Entry Into Service date, but it is said that anywhere between 1937 and 1939. The type was mostly operated by the Finnish Air Force or Ilmavoimat, who had 20 of the 24 produced production examples, the last two unaccounted for (2 prototypes and 20 Air Force examples) went to the Air Defense Guild.

During the Winter War the type's role expanded beyond the trainer duties it was originally tasked with. It served as an observation aircraft, a light transport for documents that needed quick transfer, as well as the transfer of high ranking personnel.

In the 1950s, the Viima was upgraded to have an enclosed canopy, framed canopy. The aircraft served this way for its final decade of service, having been officially retired in the late spring of 1960, however, this might have been later, since the type's replacement, the Saab 91 Safir, did not enter Finnish service until 1962, but Finnish basic air training continued in the period of late 1960 and 1961.

After the type's retirement, many saw a second life in civilian ownership. Today, two aircraft are airworthy, one, OH-VIF, looking much like it did at the end of its service life, and the other, OH-VIG, looks much like it would have in the 1930s and 1940s and flies at airshows throughout Finland.

File: FMA_Aé.M.B.2_-_two_inflight.jpg (126.0 KB)

I am tired so I will keep this short.

The FMA AeMB.1 and AeMB.2 Bombi were two very similar aircraft, both filling the bomber role for the Argentine Air Force. Constructed at the Fábrica Militar de Aviones or FMA plant in Córdoba.

The type was a single engine low wing monoplane made of Chromium-Molybdenum Steel tubing for the fuselage and wood for the flying surfaces. The type also featured a fixed tailwheel undercarriage configuration and large fairings around the main undercarriage and a turret on the top of the fuselage.

A single AeMB.1 was produced, as well as 14 or 15 AeMB.2s (figures are conflicting on this). The AeMB.1 first flew in 1935 and entered service in 1936 along with the AeMB.2s and these served until 1945.

The service life is utterly unremarkable, never having been used in combat, set any records or anything of that sort.

None of the type survive today.

Navy just didn't have interest in the design. Hall made the PH, which was a modest success and got some Navy sales, but the X2PH was designed for very long range patrols and the Navy went with less extreme designs (Consolidated P2Y). The XPTBH had great performance but failed to meet Navy speed specs. and the Navy had reservations about floatplane torp. bombers. Honestly, with retractable gear it could've been a good light/medium bomber. Hall was also one of the first companies making all-metal planes. Short was having similar problems getting their all-metal Singapore accepted by the RN, despite it being excellent.

The Waco CSO was used as an attack aircraft by both the Brazilian Navy and the Rebel Army during the Constitutionalist Revolution of 1932.

After the end of the war, the Waco was used by the Brazilian Army to deliver air-mail, till the aircraft's retirement in 1943.

File: Häfeli_DH-5_seen_from_above.jpg (698.8 KB)

I decided to now do a Swiss aircraft...

The Häfeli DH-5 was a two seat reconnaissance biplane of standard construction that first flew in 1919. It featured wooden covered fuselage and fabric covered wings and tail surfaces with a wooden frame.

There were two main production variants, but the only differences between the airframes are the engines. The first batch, the DH-5 features a 180hp LFW I engine, while the second batch (sometimes referred to as the DH-5A) having a 220hp LFW III engine. A third experimental variant, the DH-5X with a 300hp Hispano Suiza HS-42 was also produced as a possible life extension program to the type in the 1930s. This airframe crashed in 1933, being the only loss of the type.

Following the first flight the type was tested for three years before entering service in 1922, with an order for 80 eventually materializing and contracted to be fulfilled by Eidgenoessische Konstruktionswerkstaette or the Federal Construction Works. Following the entry into service, the type served a rather lackluster service career, as with many Swiss aircraft. No combat and apart from the aforementioned incident, no further mishaps of the type. What is interesting about this type is its service life and that the type saw a mid-life upgrade in 1932 with the addition of wing slats and a way for the crew to wear parachutes while inside the aircraft. The DH-5X would have been the next upgrade to the type and had it gone forth, it would have seen all airframes modified around 1935 or 1936, further extending the types operations. Despite this, the type continued flying until its retirement in 1940.

Today only one survives, being located in the Flieger Flab Museum in Dübendorf. Pic related.

This is Baltic aviation tread now
> from wiki
The aircraft was based on the Cukurs C.6 Trīs zvaigznes (Three stars) trainer which was known for its 1937 flight from Riga to Tokyo and return.[1]

Work on the C.6bis started in 1939, with the first test flights in 1940. Soon after first test flights the Latvian Air Force accepted the aircraft and ordered twelve.[1]

Test flights were halted on the 7 June 1940, just 10 days before the Soviet occupation of Latvia in 1940. During the occupation the Red Army expressed interest in the C.6bis and test flew it, but they determined that it was unsuitable for use.

My colon grew a tail...

The Couzinet 10, 11, 70 and 71 Arc en Ciel (literally Rainbow), was a French trimotor airliner and mailplane. The type was of metal and wood mixed construction for the fuselage and wooden construction for the flying surfaces. It also featured fixed gear with fairings. Power was provided by three Hispano-Suiza 12Nb V-12 engines producing 650 hp each. The only differences between the 10, 11 and 70, 71 was the size of the aircraft itself, with the 70 and 71 being larger than that of the 10 and 11.

What makes this aircraft so interesting is the that the fuselage does not necessarily have a separate vertical stabilizer, but rather one that is blended into the fuselage, not unlike the tail of a bird, or less appealingly, a whale.

A total of three aircraft were built, the first being the 10, which was later converted to the 11, the second being the 70, which was later converted to the 71 and the last was sent to Spain with the designation of 101, later converted to a 103 standard. The 101 was, for all intents and purposes, the same as the 70, just sent to a military operator (in this case, the Republican Air Force) as opposed to a civil one.

Little is known of the 10 and 11, but what is known is that the 10 flow sometime around 1925 or 1926 and was converted to 11 standard by 1928, as this was the year that the type was lost. The 70, which replaced it, did not fly until 1932, and was not ready to enter service until it became the 71 by May of 1934.

Bot the 71 and 101 (later 103) had otherwise unnotable service life, mainly carrying mail. The 71 operated specifically in the South of France for the aerial mail carrier Aeropostale (not to be confused with the Venezuelan airline named Aeropostal Alas de Venezuela, usually shorted to simply Aeropostal) and was retired sometime before 1940. Its whereabouts afterwards are unknown. A similar fate happened to the 103.

Today, all of the type are presumed to have been scrapped or destroyed.

You cannot find that information, but luckily I am close to a degree in aerospace engineering, so if I had to hazard a guess, there was less parasitic drag (the drag independent of life production) and maybe better weathercock stability (in other words, it tracks better in the yaw axis).

>>65218195
A lot of their types from when they caught up were copies or British and American aircraft.

Interesting how both French and Italian aviation changed after World War II. Being economically-industrially devastated in the war, and how for example/comparison the British aviation industry continued (at least for another few decades) on its own diverse path after the war.
