Gribovskiy aircraft

Special for Maveric (sorry about the long wait)((

V.K. Gribovskiy created an excellent gallery of planes and gliders. One can regret that in this creative work of his efforts were not focused on the detailed working out of standard types of training monoplane single and especially double.
In its products Gribovskiy expresses the idea of mass sports aviation ("flying people"), somewhat a naive...

Gribovski G-11M - Light Transport Aircraft

Powered version of the G-11, later re-designated G-30. A prototype with a M-11 engine mounted on a strutted pylon. Not developed. Further proposal for the G-11 glider to be fitted with two M-11 engines. This did not proceed beyond the design stage as the Shche-2 light glider was favoured by the Soviet military authorities for troop transportation.

POWERPLANT NO: 1 x M-11 (100 hp)
WING SPAN: 18.0 m
LENGTH: 9.71 m
WING AREA: 30.0 sq m
WING ASPECT RATIO: 10.8
HORIZONTAL TAIL AREA: 5.64 sq m
VERTICAL TAIL AREA: 2.70 sq m
AILERON AREA: 3.1 sq m
MAXIMUM TAKE OFF WEIGHT: 2,400 kgs
ACCOMODATION: 11
WING SECTION: R-II

A couple of views of the G-1 and G-30.

High wing G-10 - picture of CCCP-C280.

I think it is the same one as in the Russian Civil & Military Aircraft 1884-1969 (Nowarra & Duval) Harleyford

I wonder why the G-29/G-30 were also designated G-11. Could it have been a design by another manufacturer but built by Gribovskii?

Hi Stargazer,


but the G-11 was related to Gribovski only,and the G-29 was developed from it.

No. The Gribovskii G-29 and G-30 entered service as the G-11 and G-11M, respectively. They are not different aircraft!

The G-29 being called G-11 everywhere has always been odd. It's not as in Tu-20/Tu-95 where there is an official numeral sequence and an OKB one... There are not two G- lists for Gribovskii!
And so, since several Russian pages talk about Grokhovski designing a glider named the G-11, my question was: could it be that that Grokhovskii's G-11 might have been produced by Gribovskii (as their G-29/G-30)? I strongly feel there's a connection here but I need confirmation from someone who reads Russian fluently and/or has studied these aircraft in detail before...

Designation G-29 had experienced glider in the series, he received the designation G-11. It's all design Gribovskogo V.K.

I'm sorry but I don't understand your sentence.

Besides, I no longer take Wikipedia as proof. Anyone can update Wikipedia and reproduce their own mistakes there! I'd like to read something from a first-hand source, a Russian book or article that CLEARLY explains why the G-29/G-30 had another designation as "G-11".

According to this website, the designation "G-11" refered merely to it being a glider for 11 paratroopers.

Simple! But totally weird as a designation...

Dear Stargazer2006, and the Encyclopedia "Russia Gliders" by Dyers AP 2005 edition will be for you an authoritative edition. So there, too, the same assertion that the original airframe G-11 was designated G-29.


Уважаемый Stargazer2006, а Энциклопедия "Планеры России", автор Красильщиков А.П. 2005 года издания будет для Вас авторитетным изданием. Так вот там тоже такое же утверждение, что первоначально планер Г-11 имел обозначение Г-29

I KNOW folks! My question was NOT whether the G-11 designation was legit. It was not whether it was used or not.
It was about WHY it was used... and if you read three posts above you'll find a quote that answered the question!

Also, please STOP talking about Grokhovskii in this context! You are bringing confusion again into the topic. My assumption about G-11 was wrong. I have removed all cross-references about this question and you keep bringing up the subject! I will have to edit all your posts further I'm afraid.

What was this Gribovskiy ?.

Late notice.
This is one of the variants of the G-14MP (though slightly distorted)
Intended to be used or a low-power motor or muscular force pilot.

Excellent my dear Borovik.

It's not razrblade Gribovsky.
This is the work of another designer Chenchikovskogo (Ченчиковский)

Yes, I agree. This is a "Red Bird" (1935) by S. Chenchikovsky.
I was misled about the inscription belonging to Gribovsky, in the Czech edition/search. This explains the "violation of the proportions."

Do you have some dimensions and weights?

Thank you my dear Igor.

Height - 1.55 m, length - 4.5 m, wingspan - 12 meters, weight in the range of 55 kg. It sets strict limits for pilots. The total weight of a pilot cyclist should not exceed 120 kg, so the share of test is not more than 65 kg. wing profile TsAGI-828.

Thanks my friend

Hello,

Does anyone know where I could find the weight of the Utka (canard) project? Information on the engine would also be helpful!

Engine M-11, and weighed about 900 kg (for the second embodiment, the weight 910 kg)

Thank you!

Is there any information on how much the wings were swept in the second design?
