Romanian RM/IAR Designation (Radu Manicatide)

From Romania,

two aircraft from IAR company which had a large series of little known aircraft:
IAR-36 :it was designed for IAR company by Messerschmitt as M-36,a single
engined six seat passenger and two crew,light transport aircraft.
IAR-47 :two/three seat reconnaissance/light bomber aircraft.

From Romania,

IAR-21 :experimental two seat low wing monoplane,later developed
into IAR-27.
IAR-24 :two seat light cabin monoplane,powered by Gnome-Rhone
engine.

Designations of Romanian Designs by Inginerul Radu Manicatide

The RM series of designations begins with homebuilt designs by an adolescent Manicatide. The series continues when employed at IAR-Brasov (where he contributed to the IAR-27, IAR-37, IAR-80, JRS-79, and Bf-109G). By the early '50s, IAR-800 series designations were applied to most Manicatide's designs (the delayed wartime RM-11/RM-12 being exceptions as well as the anomolous MR-2 light transport).

Romanian RM (Radu Manicatide) Designations

Radu Manicatide worked as an engineer at the LARES repair shops (1935-1937), then at IAR Brasov (1937-1944). 'RM-' designations preceed and then overlap those periods.

RM-1 -- 1926 single-seat glider, aka M-1

RM-2 -- 1927 biplane glider, several flight tests flown

RM-3 -- Hypothetical designation for 1928 M-3 aircraft, 10-12 hp engine

RM-4 -- 1932 very light (250 kg) a/c, 12 hp Indian, max 85 km/h, 8m span
- RM-4: shoulder-winged wire-braced (cabane above) single-seater
-- NB: RM-4, designed in 1930-1932, proved too underpowered to fly
-- 3-view https://aragornblog.files.wordpress.com/2012/08/rm4-schita.jpg

RM-5 -- 1935 very light (200 kg) a/c, 30 hp Anzani, max 120 km/h, 8m span

- RM-7: 1 x 20 hp Poinsard HO-2,* span 5.0 m, empty weight 145 kg
-- * NB: René Poinsard's 1250 cc type B usually listed as 25 cv
-- Sources differ: RM-7 "designed and built" or an unbuilt project

RM-8 -- 193? [Project] Two-seat, low-wing monoplane light tourer
- R.M.8: 1 x 40 hp engine [?? type ??]*
-- * Poinsard 1550 cc type C listed as only 30-35 cv

- RM-12: scaled-down RM-11 design with open cockpit repl. RM-11's canopy
- RM-12: aka M-12, built at IAR Brasov
-- https://aragornblog.files.wordpress.com/2012/08/mr-2.jpg

MR - Radu Manicatide Designation Anomoly

For no apparent reason Radu Manicatide's intials were reversed for some designs (two are recorded below)

MR-2 - light transport (1 + 5 px), 2 x 160hp Walter Minor 6-III, 14m span
- MR-2: series production version of IAR-814, 10 built (+ 2 IAR-814 prototype)

MR-6 -- [Project] 1930 twin-engined, 8-pax a/c, designed in Paris
-- http://oferte.carpatair.com/carpatairmagazine/cm20/files/search/searchtext.xml

Another designation anomoly is the 1930 D-20 tailless aircraft concept. The AS-1 pseudonym for the RM-5 may simply refer to its type or a role.

R.M.10

Hi,


IAR-812 was developed from IAR-811 with more powerful engine,project only.


RM-7 & RM-8 were single seat and two seat respectively light aircraft,powered by one
40 hp engine for each,but they didn't finish.

Thanks for that Hesham! I've now added those. I've also filled in some gaps in the 'RM' list, added the anomolous MR-6, and added the IAR-821/IAR-821b.

Thank you my dear Apophenia.

From AeroMagazin,


there is a paragraph on Radu Manicatide designer,and a strange series "M" only and not "RM",also a strange aircraft MR-9,can anyone explain that ?.

I see the "M" series was his essential designation,later called RM,that's my opinion.

Translate,

Practically, the construction career a of Radu Manicatide started when he
he was only 14 years old in 1926! in April a that year he won first place in the first
"national competition with kites and gliders" organized at the Royal Romanian Aeroclub,
presenting himself with a conception planer and especially of own construction, one
monoplane called "M 1".

Until 1953, they want him followed other glider prototypes and
planes built as personal initiatives and having a purely experimental character.

The pianos were: M.2, biplane de Chanute type, with a bearing surface of 8
square meters and a flight weight of 100 de kilograms, built in the summer of 1927 and
tried on the slopes around the resort Sinaia, M.4 and M.5, in 1932, but especially
M.10, built at IAR Braşov in 1943. M.10 was made in the "canard" formula, o
try to avoid the traps aerodynamics of the classic formula, therefore
of the accident in which it had been destroyed MR-9 aircraft.

M.10 had the scope of the plan of 6 meters, a total area of 9 square meters
and a flight weight of 130 kilograms.
Its main characteristic was the two marginal discs of the posterior plane, with
role of double vertical empennage. This glider it was attempted at the engineless flight
center from Sânpetru. He had the opportunity to fly high, within the speed limit, without
the risk of committing and could turn without the use of ailerons2.
