In the book (The Osprey Encyclopedia of Russian Aircraft),I found under the title L.B. Kurchyevskii on pages 160 and 161 that :

he was the designer of APK series of large-calibre cannon and he
worked in USP for NKTP and he invited the aircraft constructors
to make a fighters to armed them with these guns , such as IL
and CHERANOVSKII BICh-17 fighters,after he was arrested there
were other two projects one from BICh design and the ather
from P.D.Gurshin at MAI.


I didn't know those projects but I suggest that for BICh,it was BICh-19,
because BICh-16,17,18,20,21 and 22 were well known.

For Gurshin I looked under MAI section in the book and I can't
identify it.

Hi hesham,

could you share the link with us. I would like to get more info and pics, if it's possible, about these designs not included in The osprey encyclopedia of russian aircraft 1875-1995 (I also have a copy and I'd like to fill its gaps)

Thanks in advance

Re: BICh-21 note from Stargazer2006:

The BICh-21 was a development of lighter BICh-20. It was of a similar size and general layout, but with a more than powerful engine and retractable undercarriage. It was a wooden aircraft was very stramlined, ailerons and elevons were integrated into the wing design. The project was launched in 1938 as a sportsplane and the BICh-21 was ready to fly two years later after extensive wind tunnel testing.
The only design correction implemented after the wind tunnel trials was an increased tailfin size. Flight trials started in 1941 and were interrupted by the War.

The aircraft was apparently easy to fly, it was stable and had good response to pilot input. The speed recorded for the aircraft was recorded at 417km/h.

Hi all!
Here is the BICh-5 tunnel model. The photo is from the book "100-year history of the Flying Wing" by Dmitry Sobolev (Moscow, Rusavia, 1998; ISBN 5-900078-01-9).

The BICh-5 wasn't a light bomber - it was an aircraft compared to the ANT-4 (TB-1) prototype, with similar wing area and engines power. According to Sobolev, the engines planned for it weren't BMW-VI, but Lorraine-Dietrich 12E or Napier Lyon (both types 450 hp; the first ANT-4 was also flown with Napiers). With these engines, estimated performance was better than ANT-4 had: maximum speed 227 km/h (30 km/h faster) and service ceiling 4900 m (700 m more). In early 1928, Cheranovsky sent his project to the NTK UVVS (Scientific and Technical Commitee of VVS direction). The military specialists regarded the project interesting, but decided that it's untimely to built such a plane, while the properties of Parabola layout in stability, control, and maneuverability aren't studied enough. They decided to built an experimental lightplane for this purpose. In April 1928, NTK UVVS approved the project of this light aircraft - the BICh-7; it was built in late 1929. The bomber remained on paper.

So it's more like a medium or heavy bomber with parabola wings?

After my dear Cy-27 spoke about Cheranovski designation system,and we
found the number 15 is only the gap in the series,I suggest that project
was the BICh-15,as armed cannon fighter,which mention in previous article.

Some more info on the BICh-5 (see also http://www.secretprojects.co.uk/forum/index.php/topic,467.msg179466.html#msg179466)

There was an article entitled "Parabolas and Other Unusual Aircraft of Designer B I Cheranovskiy" in the Russian Aviation Research Bulletin, issue number 160. It was written by Mikhail Moslov and covers most of the BICh types.

He has this to say about the somewhat elusive BICh-5 design:

BICh-5 (BICh No. 5)

In 1926, developing his ideas, Cheranovskiy designed a project of two-engined heavy bomber featuring the flying wing layout. On the whole, the proposed airplane corresponded to the TB-1 (ANT-4) bomber, designed by TsAGI (Tsentralniy aero-Gidrodinamicheskiy Institut, or the Central Aero-Hydrodynamic Institute), as far as its characteristics and purposes were concerned. The proposed layout promised very good defensive capability. A wind tunnel model of the aircraft was built in 1927. Its tests proved efficiency of employing elevators and ailerons of concaved profile. One of the first BICh-5 project versions featured the following performances: wing span of 27 m, maximum wing chord of 7.5 m, and flight weight of 5,500 kg.

On 12 August 1926 Cheranovskiy developed a project of a 28 seat passenger airplane under BICh-5 designation. The aircraft was planned to be powered by two 185hp BMW engines. The approximate cost of the project realisation was estimated at 18,000 roubles.

The BICH-5 project was not realised, while its main ideas were used in the BICh-7 airplane in 1928-1929.

Characteristics and performances of the BICh-5 (final version of the bomber)

Wing span, m 30.0
Maximum wing chord, m 9.0
Wing area, sq.m 180.0
Empty weight, kg 2,860
Flight weight, kg 4,860
Wing load, kg/sq.m 31.6
Empty speed, km/h 170-185
Landing speed, km/h 70-80
Service ceiling, m 2,100

A image of the wind tunnel model was also included. So it seems the designation may have been used for a passenger transport and bomber variants.

I have found this glider-bomber concept drawing (source unknown), but I am not sure if it is a Cheranovsky design.

It is a fairly well-known fact that in the second half of 1931 Korolev began flight testing the Cheranovskii BICh-8 tailless airframe design.

In 1931 Korolev published an article in issues 11 and 12 of the magazine "Samolyet", which told the story of a whole series of tests with this glider. The article mentions only one date, September 29, when a speed detection glider flight was carried out. Apparently, Korolev started tests with the BICh-8 before that date, since at least four undated flights are alluded to. According to the article, Korolev personally conducted all the tests to evaluate the design features of the BICh-8 and its technical characteristics.

Zander and Korolev met at Osoaviahima airport on October 5, 1931, during the test phase of the BICh-8, and although documentary evidence is missing, it is safe to assume that in one of his diary entries Zander was referring to that glider: "It (i.e. the Korolev glider) has been painted triangle — a fact also noted by author Vladimir Komarov but usually omitted when quoting in other publications. Because of the unusual shape of the wings, the glider's second name was "Delta". This particular name was also used in Korolev's article, along with the name BICh-8.

Subsequent events confirm the validity of this version. Zander wrote in his diary that on 7 October (the day after the meeting at the Osoaviahima airport), Korolev and BICh-8 designer Cheranovskii presented the 32-m OR-1 liquid jet engine test prototype. From this we can conclude that the October 5 at the airport was apparently aimed at discussing the creation of a jet plane — a subject dear to Zander — using the BICh-8 as a basis, and the meeting on October 7 indicated the preliminary agreement on the matter. And most importantly - it was after these two meetings that Zander began developing the OR-2 engine, which was intended to be created in the GIRD's RD-1 rocket plane, which had the same structural scheme as the BICh-8 glider.




Translated/adapted from:

Речь идет о факте достаточно известном: во второй половине 1931 г. Королев приступил к летным испытаниям планера конструкции Черановского БИЧ-8, выполненного по бесхвостой схеме.

Королев опубликовал статью13 в № 11/12 журнала «Самолет» за 1931 г., в которой рассказывается о целой серии, испытаний этого планера — семи пробежках и 12 полетах. В статье упоминается только одна дата — 29 сентября, когда проводилось определение скорости полета планера. По-видимому, Королев приступил к испытаниям БИЧ-8 до указанной даты, так как определение скорости проводилось, скорее всего, при полете с верхнего старта московской планерной станции, а таких полетов, как указано в статье, было четыре (причем последние по счету). Королев лично провел все испытания, изучил особенности конструкции БИЧ-8 и ее техническое состояние, о чем написал в статье.

Нетрудно згметить, что упомянутая встреча Цандера и Королева проходиia в период испытания планера БИЧ-8, поэтому естественно предположить, что Цандер в дневниковой записи имел в виду именно этот планер.

В оригинале дневника Цандера после слов: «его (т. е. Королева) планера» нарисован треугольник (На этот факт обратил внимание автора В. М. Комаров.), который в публикациях при цитировании обычно опускается. Оказывается, этот неприметный значок является недостающим документальным фактом, позволяющим считать, что во время встречи Цандера и Королева на аэродроме Осоавиахима 5 октября 1931 г. демонстрировался именно планер БИЧ-8. Этот планер из-за необычной формы крыльев в плане имел второе название «Треугольник». Такое название, в частности, использовал в своей статье Королев наряду с названием БИЧ-8.

При склонности Цандера к применению стенографии условная запись в дневнике, соответствующая названию планера, была для ученого делом естественным.

Последующие события подтверждают справедливость такой версии о БИЧ-8. Цандер в своем дневнике записал, что 7 октября, т. е. через день после встречи на аэродроме Осоавиахима, Королев и конструктор БИЧ-8 Черановский присутствовали при очередном, 32-м испытании опытного прибора ОР-1, на котором обрабатывались отдельные элементы жидкостного реактивного двигателя. Отсюда можно заключить, что 5 октября на аэродроме речь шла, по-видимому, о создании реактивного самолета, к чему так стремился Цандер, с использованием БИЧ-8, и встреча 7 октября свидетельствовала о предварительной договоренности по этому поводу. И самое главное — именно после этих двух встреч Цандер приступил к разработке двигателя ОР-2, который предназначался для создаваемого в ГИРДе ракетоплана РП-1, имевшего такую же конструктивную схему, как планер БИЧ-8. Подробнее об этом и о том, какую роль сыграли Цандер и Королев в организации ГИРДа,— в следующей главе.

(Continued):

By the end of the airframe tests, the BICh-8 proved unsuitable for further use. There were vibrations, which Korolev attributed to the poor condition of the airframe caused by adverse storage conditions. However, the conclusions of Korolev's article on testing the BICh-8 were still positive. It was easier to get the replacement of the old glider BICh-8 new sample for the forthcoming tests of the rocket plane variant than repair the damaged one. After meeting with Korolev and negotiating the use BICh-8 to create a rocket plane, Zander had reason to look to the future with some hope. He immediately took up the development of the jet engine.

(Adapted from the same source:)

The prospect of the engine OR-2 was becoming clearer: it was completed for the BICh-11 glider. On February 22, Korolev began to test the airframe. The BICh-11 glider was commissioned and constructed, but with the case for the engine was thoroughly stuck. No one wanted to take up its production.

Believed to be his first glider design, the Cheranovsky Ornithopter from 1921.

The same photo appears in Bulletin of the Russian Aviation Research Group of Great Britain #160 which specifies the date and place as 1st December 1921 in Moscow .

Still a bit of confusion, but I've tried to sort out a bit of the mess between this topic (Early Projects thread) and the one in the Designation Systems section, which can be found here:
http://www.secretprojects.co.uk/forum/index.php/topic,18625.0

Please let's keep this here thread for all specific data on the various prototypes and projects, and keep the other one for listing the designations and discussing them!
