Thank you! This really helps!

I understand that the two halves of the rear wing changed incidence was used for roll and pitch control.

However my translation of Krasilschikov isn't reliable. Did the aircraft have yaw control? Could the pilot control the rudders on the tips of the rear wing? Thanks!

Also attached is a poor quality scan of a photo showing a slightly different angle.

Hi,

and MAK-15,does anyone know more ?.

RE: MAK-15

My notes refer to M.A.Kuzakov and not M.A. Kuzkan but this may be down to my translation way back at the turn of the century (no online translators just a scrawl in a notepad!).


DESIGNATION: MAK-15 (Glider)
WING SPAN: 10.4 m
LENGTH: 5.32 m
HEIGHT: 1.85 m
WING AREA: 12.56 sq m
WING ASPECT RATIO: 8.6
STABILISER AREA: 1.00 sq m
FIN AREA: 1.25 sq m
KEEL AREA: 0.60 sq m
RUDDER AREA: 1.00 sq m
AILERON AREA: 1.70 sq m
MAXIMUM TAKE OFF WEIGHT: 135 kgs
ACCOMODATION: 1
WING LOADING: 17.9 kgs sq m
WING SECTION: R-III
SINK RATE: 1.00 m per second
MAX AERODYNAMIC QUALITY: 17


MAK-15M (Motorised Glider)

Between 1956-57 the MAI laboratories began modifying a standard M-15 glider to be powered and have vibrating slats. Designer M.A.Kuzakov (M.A. Kuzkan?) provided the aircraft, A.I.Boidyrev devised the vibrating slat system and the drive mechanism.

The engine was from Polyakov and a development engine evolved from his earlier VP-760. The slat took up about 66% of the leading edge.

The engine was mounted adjacent to the centroplane. Experiments showed the functioning slats caused extensive fatigue in the wing structure causing failures. The programme of development ceased when this occured in 1957.

POWERPLANT NO: 1
POWERPLANT TYPE: Polyakov VP-760
POWERPLANT CAPACITY: NOT KNOWN
WING SPAN: 10.85 m
LENGTH: 5.64 m
HEIGHT: 1.5 m
WING AREA: 13.15 sq m
WING ASPECT RATIO: 9
STABILISER AREA: 1.00 sq m
FIN AREA: 1.25 sq m
KEEL AREA: 0.60 sq m
RUDDER AREA: 1.00 sq m
AILERON AREA: 1.70 sq m
ACCOMODATION: 1
FIRST FLIGHT: 1956

and for Mr. P.A. Ivensen,the I-1 was a glider Project of 1926,the I-2 was alight aircraft as in Various pre-war Soviet projects
topic,the I-3 was a single seat glider and the I-4 was a high performance sailplane,derivative from I-3 as my dear Cy-27
explained,the I-5 was a postal transport aircraft,I don't know if it was built or not,the I-6 was a single seat low-wing sailplane.

See also:
https://www.j2mcl-planeurs.net/dbj2mcl/planeurs-machines/planeur-fiche_0int.php?code=3142 for more on the PAI-6 (in French)

https://klubfedotova.ru/uk/zhiroszh...riya-planernyi-klub-buzovaya-odin-iz-vzletov/ states ....

"In the postwar period, besides the serial gliders A-9, A-10, A-11, A-13 and A-15 OK Antonov were produced, in small batches were issued MAK-15 M. Kuzakov (1952), PAI- 5 and PAI-6 L.Pietsukh (1949), Sh-16 and Sh-18 B. Sheremeteva (1951) "

so perhaps these should appear as post war types?

I have some details on the CO-1 and CO-2 mentioned above, from the book Gliders of the Soviet Union by A P Krasilshikov (1991) ISBN 5-217-01048-7. Unfortunately its in Russian and I don't have a translation to hand at present. I hope it helps.

A. I. Pietsukh at the age of 16 built the world's smallest glider (PAI-1), independently learned to fly it and demonstrated it at the aviation festival in Kiev. At the Osoaviakhim glider factory, under the leadership of O. K. Antonov and B. N. Sheremetev, they created the PAI-2 glider ("Pavel Golovin") and the PAI-3 glider. At the glider school, where the author of the book worked as a teacher, he created the design of the tailless glider PAI-4.
After the great Patriotic war, working as a senior test pilot, A. I. Pietsuh designed and built the PAI-5 and PAI-6 gliders
PAI-7 project 1954 ( page 287 of the book "Wings of youth" Pietsuh 1954)
