Junkers Ju-86 paper bomber model
The paper model of the Junkers Ju-86 bomberis a German high-altitude medium bomber, created in the Junkers design bureau under the direction of E. Tsindel.
Materials and tools:
- scissors, paper knife, drawing ruler
- glue brushes and paint;
- watercolors (or pencils), toothpicks;
- clear acrylic glue ("Moment", etc.);
- to print the model matte photo paper with a density of 170-180 g / m2; for small parts - 70-80 g / m2.
- Before you assemble the part, read the drawings and instructions. Determine the place of each part and imagine its assembly;
- Make holes in details before cutting out the part;
- Cut only the part (s) you need right now. Unpacked items in a box, and unused sheets in a closed folder (as an option). Throwing out trash after work, carefully inspect the scrap paper;
- for the best bending of the part, it is necessary to draw a ruler along the fold line, slightly pressing,the blunt side of a knife or a toothpick so as not to damage the surface of the paper. Better to do it from the wrong side of the part;
- Keep your fingers clean and be sure to use wipes to wipe your hands, because hands may get dirty in the process;
- wind up cylindrical parts before gluing onto a round object of a suitable diameter, this will give them shape;
- Before gluing it is necessary to paint the ends of the part. White crop lines spoil the overall look of the model. To paint the ends, use watercolors or gouache paints. After selecting the desired color, apply them in a thin layer, then allow the paint to dry. About markers better to forget;
- Take your time with gluing. First, cut out the part, paint it from the end, wait for the paint to dry, assemble the part. Attach it to the place where it should be to make sure everything is done correctly. And only then stick. Do not forget to let the glue dry.
A bit of history
German high altitude bomber Junkers Ju-86
Junkers Ju-86- German high-altitude medium bomber, created in the Junkers design bureau under the direction of E. Zindel.
The first flight took place on November 4, 1934.Option Ju-86A-1 was adopted by the Luftwaffe in February 1936. Passenger Ju-86B-0 Lufthansa received at about the same time.
Ju.86 was the development of single-engine Ju.60 and its version Ju.160. Twin-engine all-metal monoplane with two-tail. The fuselage has an oval cross section and a two-spar wing with a smooth skin. During the first flights of the experienced Ju.86ab1, which did not have weapons, a number of shortcomings were revealed, the main of which was a bad reaction to the steering wheels, and the longitudinal stability was also insufficient.
Although the project was notable for its many innovations, the engine specifications were bad. When the war began, the aircraft was quickly removed from the front, although the high-altitude specimens remained as scouts. The pilots complained about the lack of review from the cabin of Ju.86, and many copies were damaged in accidents during landing, when the pilots were losing sight of the ground at the approach.
It was produced in versions of the bomber and (c 1940) - high-altitude reconnaissance (Ju-86R-1 and R-2). In 1937, the Ju-86E-1 with star-shaped engines of the BMW 132 entered service.
A four-seater bomber with an extended fuselage and increased fuel capacity.Five Ju-86D-1 (with modified tailing fairings for better control) were tested in combat conditions by the Legion "Condor". The shortcomings of the Jumo diesel were revealed.
A Ju.86P-1 high-altitude bomber capable of carrying 4x250 kg or 16x50 kg of bombs. Originally designated Ju.86H, this variant appeared as Ju.86R. To the fuselage of Ju.86D «Junkers» added a new double hermetic cabin, the pressure in which was maintained equivalent to an altitude of 3000 m. This was achieved by boosting the air taken from the left engine supercharger, and the cabin was constructed with multi-layer plexiglass glazing filled with dry air. The crew got into the cockpit through a round hatch, located at the bottom on the starboard side. There were no defensive weapons. The fuel reserve was 1000 liters, which provided a 4-hour flight.
The Ju.8BR VI prototype took to the air in February 1940, and in March, the V2, both aircraft with Jumo 207A-1 diesel engines reached an altitude of more than 10,000 m.
In early 1942, the Germans realized that the Allies could soon create an interceptor that could easily cope with Ju.86P, so in mid-1942 the Ju.86R, based on Ju.86P, flew into the sky.On the wing, enlarged to an incredible size - 32 m, the modified Jumo-207B-3 were installed, which developed 1000 hp on takeoff. and 750 hp at an altitude of 12,200 m, and the use of the afterburner GM-1 provided a high altitude. A fuel reserve of 1935 liters provided a flight duration of 7 hours and 10 minutes. The three-bladed screw was replaced with a four-bladed screw, which made it possible to reach a ceiling of 14,400 m.
Modifications of notation in relation to the P series were reversed - the Ju.86R-1 became a reconnaissance aircraft, and the Ju.86R-2 became a bomber
By January 1941, a group of four squadrons Ju.86P was formed. Acting from Northern Germany, they made combat and reconnaissance flights over the British Isles. In preparation for the operation, "barbarossa" » German aerial reconnaissance was able to identify the defense system of the opposing Soviet forces, the location of their command posts and virtually all Soviet airfields. A significant portion of this information was obtained using the Ju.86P reconnaissance aircraft flying from airfields near Budapest and Krakow. With the beginning of the invasion of the Soviet Union on the Eastern Front, three squadrons of the group were deployed, the fourth remained in the West and continued to conduct reconnaissance from the extreme heights.
In 1941, the high-altitude Ju.86 made unpunished flights over Moscow, conducting aerial reconnaissance. The aircraft in service with the USSR turned out to be unprepared for firing at high altitudes at low temperatures. It was urgently necessary to arm the air defense with high-altitude fighters and oxygen equipment.
In 1943, on the instructions of the State Defense Committee, the Lavochkin Design Bureau began work on the creation of a high-altitude fighter by installing the CIAM design of a TAC-3 turbo-compressor on a La-5 plane. To obtain a ceiling height of about 14 km, in addition to the TK installation, the wing area and tail area were increased, a new propeller was installed, a reservation and one gun were removed. However, during the factory tests the plane crashed.
In 1944, work on the creation of high-altitude fighter were continued on the basis of the serial La-7. In July 1944, factory testing began. Due to the lengthy refinement of the VMG with TK, the testing of one of the experimental machines, which received the factory index "116", continued until early 1946, after which they were discontinued as no longer relevant.
The hopes pinned on the Yak-9PD with Dollezhal superchargers, and on the MiG-11 with turbo compressors, were not realized either.Soviet aviation was not able to oppose the German Ju-86.
Although during the raids on Britain, Ju.86R was often dropped on different targets by just one bomb, but it was like an eyesore to the fighter aircraft of Britain. It took a great deal of effort to stop the “Junkers”. For interception was prepared hastily modified «Spitfire»MkVIwithasealedcockpitandawingofincreasedspan,butnoattemptwassuccessful— only in one case did he manage to open fire on the Ju.86P that was above him, and right there he lost speed. “Junkers”, diving, descending from a height of 12,200 m to 150 m and disappeared from view of the “Spitfire”. The last 12 bombings of Britain, these aircraft carried out on September 9, 1942.
Despite the fact that the interceptors repeatedly found Ju.86, they could not hit them until August 24, 1942, when the specially facilitated «Spitfire»MkV,departingfromabaseinAboukir(Egypt),interceptedJu.86Pandshotitdownatanaltitudeof12,800metersnorthofCairo.Onthe“Junkers»ImmediatelyinstalledaretractablegondolawithaMG-17machinegunforfiringbackbelowthefuselage(whendeployedtoacombatposition,thespeedofflightdropped)but«Spitfire» from Abukir soon two more Ju.86P were shot down, and squadron 2.
