Hi,

the Grigorovich MM was a marine mine carrier aircraft project,it was
a monoplane with wooden wing(slightly scaled-down ROM-1) ,twin
float twin tail booms and tandem Lorraine Dietrich 450 hp engines
above cetral nacelle,it was never completed.

Re: Grigorovich MM project

according to Bill Gunston's "Russian aircraft", MM is for Morskoi Minonosyets (I could check in my Russian dictionary, but one of our Russian friends could translate more easily).
Construction begun in 1928 but not completed.
A drawing would be much welcome...

Re: Grigorovich MM project

It's seems the full designation of aircraft was Grigorovich MM-1 and the project was of 1927.
That's all what I know about it.

Re: Grigorovich MM project

By Grigorovich, with the designation MM-1 (MM), there were at least two of the project.
The first draft of 1923-24 - a biplane, and the second - 1925-27, monoplane which indicates Hesham.

Looks rather French--like something from the LeO stable.

Hi!

Sorry for interruption
I presume WIG means Wing-In-Ground (http://en.wikipedia.org/wiki/Ground_effect_vehicle)
In Russian, as far as I knew there were single word, that determines such kind of vehicles - "Экраноплан"
(Ekranoplan).

Cheers!

Re: Grigorovich MM project

Alas, other information, except for 3 species in the book "Russian seaplanes and WIG types 1919-1999" - "Гидросамолёты и экранопланы России 1919-1999" by GF Petrov not.
Through find Stephane / Stargazer2006

This remarkable book has become a universally accessible ...
(see page 231 / 234 /)
Regarding the data on these two projects need some time.

Re: Grigorovich MM project

I refresh this topic hoping for the further informations about the Grigorovich MM-1,
especially of the second later design of 1927 *, promised by borovik.
I looked at the page 231 of the Petrov's book, but there were only Akkord, Ładoga
and Ptieniec descriptions.

* Tophe's 1928.

seems was influenced by bimotors of Leo and Farman, aesthetically remember me french bi-engined aircraft of awesome period !

Re: Grigorovich MM project

OK. I give up. I see only the Projekt gidrosamoleta Grigorovicha MM-1 1923 - 1924.
Now let anybody only assure me there wasn't MM-1 project of 1927 / 1928 and I go to my pub.

MM-1 second with this name
Year: 1925-26
engine: 2 Lorraine Dietrich of 450hp
span: 27,4 m
ar.wing: 116,4 m2
lenght: 18,4 m
performence:
max speed: 160km / h

armament: four turret TUR-5
Splice with 2 x guns DA caliber 7,62 mm
A torpedo x 450mm (790-900kg)

It is interesting, but it was not the last project with the designation MM (MM-3), later renamed the MT-1 (MT1-2LD450).
It was a flying boat, a biplane with the engines between the wings. The only torpedo was suspended under the wing next to the board. Designing was halted at the stage of detail.
In a similar aerodynamic scheme - two boat / catamaran, in the USSR in 1920-30 years were designed as:
(Blessed memory Savoia Marchetti S.55, devoted.)))
Bartini MTB-2 (1929)
Tupolev MTBT (ANT-11) / second version / (1929)
Tupolev MK-1 (ANT-22) (January 1933)
TsAGI-gydrosamolyot (1938)

PS Boogey sorry to have kept you waiting long.

Thanks Borovik.
I thought this scheme was called "twin-hull" ("bicoque" in French, maybe related to the Russian Bi-Kok).
I am not sure I have ever seen the MTB-2 and TsAGI one and ANT11, but the ANT-22 was rather different: the two hulls carried their tails. Here on your MM-1 the unique layout is that there are both twin hulls (boats with pilot/passenger) and, separately, twin booms. (The S-55 had twin-hulls and several booms).
VERY interesting, thanks again! ;D
