Oberlerchner, Joseph

Austria
The firm of Josef Oberlerchner Holzindustrie had become the foremost Austrian sailplane manufacturer, producing over 4,000 gliders and powered aircraft between 1941 and 1967, of which the Mg 19 tandem two-seater trainer and the Mg 23 high performance single-seater were the most important postwar types. Before the war Austria had produced some notable sailplanes, in particular the Mg series designed by Ing Erwin Musger which culminated in the Mg 19 and Mg 23.

A former manufacturer of sailplanes, Oberlerchner flew a prototype all-wood two-seat JOB 5 lightplane in 1958. The developed JOB 15 four-seater, which had metal/wood/glassfibre construction, entered production in 1961, powered by a Lycoming engine. It remained in service with Austrian and other European aero clubs, especially as a glider tug.

Nyuxtikov N-4

The N-4 (Russian: Нюхтиков Н-4) glider was conceived as a low-wing glider in a tailless configuration and featured a wing with a 30º sweep and a wingspan of close to 15 meters. Longitudinal and transverse control of the glider was obtained through elevons located on the wing leading edge and the directional one through surfaces located in the lower part of the wing, mediated by the wingspan.

Nyuxtikov put special emphasis on improving the view from the cockpit. The landing gear included a tail wheel located at the base of the empennage.

The N-4 was never finished, even though its construction began in 1932 in the Kacha circle of interest. The main reason for his abandonment was the change of direction in the flight school that decided to prioritize the physical preparation of the pilots over their technical or design capacity. Unfortunately Nyuxtikov did not finish this interesting project in which they included several new details.

In the construction of the N-4 the stringers of a destroyed Polikarpov R-1 were used, as well as various elements of its flight control system. Due to certain doubts about the maneuverability and resistance of the device in the absence of its creator (since July 1933 Mikhail Nyuxtikov had started working as a test pilot on the NII VVS) the glider was never tested.

A scale copy built by technician Bugovsky at Kacha flew without difficulty.

Nyuxtikov had considered the possibility of equipping this glider with a 400 hp Liberty engine obtained from the R-1 itself, turning it into a tailless plane.

Nyuxtikov N-3 Motiliok

Between 1932 and 1933 under the leadership of Nyuxtikov, the members of the Sevastopol circle of interest would develop a new model of glider that received the name “Motiliok”.

The “Motiliok” was designed as a high wing glider braced by struts and with a high tail bar. The wing, with a single spar, was rectangular in plane, with slightly curved ends and a G-652 type profile. The lar bracing was carried out using cables.

The fuselage was conceived in the shape of a gondola covered with fabric, which ended with a wooden bar located high, just at the exit of the wing trailing edge. At the rear end of this bar was the conventional tail with triangular stabilizers to which the elevator rudders were attached and an empennage with offset rudder.

The landing gear consisted of a wooden ski with no depreciation.

Built at the Kacha Flight School, the “Motiliok” glider was entered in the IX Koktebel National Sailing Competitions, held in 1933.

The evaluation commission considered that the glider had been calculated for very small loads, therefore the structural resistance of the wing and the tail planes was insufficient. For this reason the “Motiliok” was not approved to perform the flights in the competition.

Nyuxtikov N-2 Sebastopoliets

In 1930 the brothers Mikhail and Konstantin Nyuxtikov developed the “Sevastopoliev” glider. The idea came after they tried to fly without success the single-seater “Koktebel” glider from SP Koroliov and SN Lyushin. The glider was very heavy so the brothers decided to develop a lighter model.

The circle of aeronautical interest of Sebastopol had tried to produce the two-seater glider Kudeyar of AN Sharapov, but desisted as too large. This group of boys aged 15 – 16 years worked on the new model that was ready in a month, using for its development parts and pieces obtained in the naval aviation repair shop. The wing profile selected for the “Sebastopoliets” was E-385.

Built at the Kacha Flight School and first flown in the fall of 1930, the first flights were made by the main builders Mikhail and Konstantin Nyuxtikov and then all the other guys flew.

The “Sevastopoliev” glider participated in the VII National Flying Competition held in Koktebel in 1930. Despite its poor characteristics, this glider underwent intense preparation during the competition. The instructors were Vladimir Verzilov, Konstantin Nyuxtikov and Vladimir Oblachko.

The circle of interest in aviation led to the formation of a flight school which was soon equipped with gliders “Standart” of Oleg Antonov and IT-4 of IP Tolstix , both flown successfully in competition Koktebel.

Nyuxtikov N-1 Kachiniets

The Nyuxtikov N-1 Kachiniets (Russian: Нюхтиков Н-1 Качинец) was the irst glider developed by Mikhail Nyuxtikov at the Kacha flight school in 1929.

Its construction began in 1929. Its wings were obtained from the Pegas glider, which was destroyed two years earlier. The landing ski, the empennage, and the elevator and steering rudders were designed by Nyuxtikov. The tail cone and another set of pieces were taken from an un-used Fokker, the seat and the control lever of a Morane O.

The glider was built under the direction of Nyuxtikov with extensive participation from PM Stefanovski, instructor pilot M Moiseyev, technician Butovsky and G Gribakin.

The glider received the name “Kachiniets” and was used as a trainer at the Kacha Military Pilot School, characterized by being a difficult glider, capricious and little tolerant of pilots’ mistakes.

Nyuxtikov, Mikhail Alexandrovich

Mikhail Alexandrovich Nyuxtikov (In Russian: Михаил Александрович Нюхтиков) was born in Chardzhou (now Türkmenabat), Turkmenistan, near the border with Uzbekistan, on June 16, 1906. In this city he finished middle school.

In 1927 he completed the Leningrad military-theoretical school of pilots and in 1928 he finished his training at the Kacha Military Higher School of Pilots (KVAShL) named AF Myasnikov in Sevastopol, where he continued working as a flight instructor.

During these years in Kacha, Mijail Nyuxtikov, together with his brother Konstantín, developed a set of gliders with the support of aeronautical circles of interest, so popular at the time.

From July 1933 Nyuxtikov was transferred to the NII VVS, participating as a test pilot in the tests of the Túpolev TB-1, TB-3 and Boljovitinov DB-A bombers. On November 10, 1936, aboard the Boljovitinov DB-A and with 10,000 kg of cargo, he reached 7032 meters in height, setting a new world record.

In 1938 he participated in the Battles of Lake Jasan and a year later in the Battle of Jaljin Gol against the Japanese. In 1940, together with PM Stefanovsky and VI Zhdanov, he was selected to test the models developed by the specialists imprisoned in the TsKB-29 NKVD, corresponding to the completion of the entire test program of the Túpolev “103” that would become the famous Tu-2 bomber.

From 1941 he participated as a pilot in the Great Patriotic War, working on the adaptation to the Tu-2 in combat units.

At the end of the war, he initially worked in the VVS and then went on to the OKB of Túpolev, being in charge of the tests of transcendental models such as the Tu-95 or the Tu-114 passenger plane. In this plane he made several historic flights to Javarosk, Paris, Beijing and New York.

As a test pilot he had 232 aircraft and 15 gliders to his credit.

By resolution of the Presidium of the Supreme Soviet of the USSR of May 1, 1957 and for his merits in the preparation of military technique, showing courage and heroism, he received the title of Hero of the Soviet Union.

In April 1963 he retired, dying on May 5, 1998 in the city of Zhukovski, near Moscow.

N-3 “Motyliok” – Glider produced by the Sevastopol circle of interest under the direction of Konstantin Nyuxtikov between 1932 and 1933.
N-4 – Flying wing type glider started in 1932 in the Kacha circle of interest. It was not finished.

Nyborg TGN.1

The Nyborg TGN.1 was a single seat experimental sailplane designed by T.G.Nyborg of Worcester, UK. Probably just one was built, but possibly as many as three.

Last flown in the late 1950s, it later went to the Midlands Aircraft Preservation Society and was stored at Solihull as BAPC.25.

Northrop Primary Glider / Zogling

The “Northrop” is an American copy of the “Zogling” which was designed in Germany in the 1920s as a training glider. Apparently, the Northrop primary glider takes its name from a Marvin Northrop of Minneapolis who imported a Zogling from Germany and from that glider had plans drawn and published in Modern Mechanics in 1930.

Thousands of Primaries were built all over the world starting with the Grunau 9 by Edmund Schneider. The Zogling was copied and modified by many. In Britain Slingsby got started with a copy called the “Dagling”
