Paper model of the Bell P-39 Airacobra fighter

The paper model of the Bell P-39 Airacobra fighteris an American fighter of the Second World War period, characterized by an unusual design for its time (the engine was located behind the pilot's cabin). Half of all cobras, “over 4,500 vehicles,” were supplied to the USSR under lend-lease. Such effective aces as Alexander Pokryshkin and Grigory Rechkalov flew on the P-39. It was in service with five countries: USA, UK, USSR, Portugal and Australia.

Materials and tools:

  1. scissors, paper knife, drawing ruler
  2. tweezers;
  3. glue brushes and paint;
  4. watercolors (or pencils), toothpicks;
  5. clear acrylic glue ("Moment", etc.);
  6. to print the model matte photo paper with a density of 170-180 g / m2; for small parts - 70-80 g / m2.

Build Tips:

  1. Before you assemble the part, read the drawings and instructions. Determine the place of each part and imagine its assembly;
  2. Make holes in details before cutting out the part;
  3. 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;
  4. To better fold the part, it is necessary to hold the ruler along the fold line, pressing lightly with the blunt side of the knife or a toothpick so as not to damage the paper surface. Better to do it from the wrong side of the part;
  5. Keep your fingers clean and be sure to use wipes to wipe your hands, because hands may get dirty in the process;
  6. wind up cylindrical parts before gluing onto a round object of a suitable diameter, this will give them shape;
  7. 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;
  8. 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

Bell P-39 Airacobra Fighter

 

Bell P-39 Airacobra - American fighter of the Second World War, characterized by unusual for its time design (the engine was located behind the pilot's cabin). Half of all cobras, “over 4,500 vehicles,” were supplied to the USSR under lend-lease. Such effective aces as Alexander Pokryshkin and Grigory Rechkalov flew on the P-39. It was in service with five countries: USA, UK, USSR, Portugal and Australia.

The Air Cobra is the first production car of the Bell Aircraft Corporation in Buffalo, New York. ».LawrenceD.Bell-theheadofthecompany,RobertD.Woods-thechiefdesigner,hisassistant-GarlandM.Poyer.ThelasttwoarethecreatorsoftheP-39.TheUnitedStatesAirForcein1936offeredtodeveloppreliminarydesignsoffighteraircraftforaviationcompaniesforconsideration.&Nbsp;

On May 18, 1937, the draft of the future Air Cobra, submitted to the competition, was a draft “Bell Model 4”, and on October 7, the company received a contract for the construction of a prototype under the designation “XP-39”.On December 29, 1938, disassembled by rail, the car arrived at the test center (Wright Field, Ohio). Alterations and fine-tuning the car stretched out until February 8, when it was possible to start the engine of the aircraft. But after the first taxiing (March 1, 1939), due to the deficiencies of the cooling system, the engine had to be dismantled. The first flight took place on April 6, 1939 (pilot James Taylor), without weapons and armor aircraft reached a speed of 628 km / h with a flight weight of 2.5 tons (according to other sources, 603 km / h at 2768 kg). Even before the end of flight tests, the US Army on April 13, 1939, and «Bell»signedacontractfortheconstructionofthefirstseries-13cars.ThecarwasextensivelytestedinNACA(NationalAeronauticsAdvisoryCommittee,nottobeconfusedwithNASA).Accordingtohisrecommendations,thecompanyintroducedchangesintotheprototype,thereweresomanyofthemthattheaircraft,convertedinNovember1939,receivedtheintrafirmname"BellModel12",andinthearmy-"XP-39B".Thepowerplantwasreplaced:insteadofthemotor&AllisonV-1710-17»(1150hp)withaB-5turbochargerwasinstalledon«AllisonV-1710-39» (1090 hp). At the request of the military, the turbocharger was removed - the car had ceased to be high-altitude forever. In addition, it became heavier to 2.9 tons, the speed dropped to 603 km / h (4500 m), and it took 7.5 minutes to climb 6,000 m.

Design

Single, single-engine, all-metal low-carrying monoplane with a low-wing and three-post chassis. The frame of the fuselage of the two box spars for the entire length. The wing of the plane is three-spruce. Spars duralumin (except for the rear steel). Sheathing working dural. Control surfaces are covered with canvas, trim tabs are plastic. Screw three-blade (steel blades), variable pitch, type «CurtissElectric» diameter 3.16 m. Could work as a screw-machine and as a screw fixed pitch. Engine cooling system - liquid. The carburetor suction nozzle was located behind the cab lantern on top, the radiator air ducts in the wing root.

Reservations

Rear armored glass with a thickness of 63 mm. Front (mounted in the visor) - 37 mm. Bronespin pilot and armor behind the engine, closing the oil tank - steel thickness of 6.5 mm Weight of metal armor 92 kg, weight of armored glass 27 kg.

Armament

The 20-mm cannon HS-404 (60 rounds of ammunition), or the 37-mm M4 cannon (30 rounds of ammunition), 12.7-mm machine guns «Browning» M2 (ammunition 200-270 cartridges per barrel), from two to four machine guns, depending on the modification.

&Aerocobra»

On April 13, 1940, the British Commission on Arms Purchases ordered 675 Bell Model 14 cars. The contract stated that the maximum speed should be 644 km / h, the working ceiling is 11000 m, the flight distance is more than 1600 km. The contract data was based on the characteristics of the experimental prototype YP-39. These requirements were met only on a modified machine with serial number AH571. In mass production marketed with the P400 index (serial numbers AH570-AH739), these requirements were not met. It was supposed to deliver 150 vehicles under the lend-lease in 1941, but in practice the British Air Force received only two aircraft. This modification for the British Air Force received the name «AirCobra»anddifferentfromtheAmericanversionofweapons:20-mmcannon"BritishHispanoMk.404»(Shop60rounds)and4x7,62-mmmachineguninthewingsorEnglish7,69mmmachineguns«Browning». On October 9, 1941, the British Aero Cobra carried out their first and only combat mission to attack. Already in December 1941, the aircraft was decommissioned by the Royal Air Force, as the British aviation industry began producing more advanced machines of its own design.

«AirCobra» in the USSR

A total of 4,952 P-39 "Aero Cobra" fighters were delivered to the USSR under Lend-Lease, which is about half of the total number of cars produced. From December 1941, Great Britain sent 212 P-39s to the USSR, but this year only one car was received; in the next, 1942, - 192. The delivery of these early models was completed in January 1943. All the vehicles arrived mainly at the 6th reserve airborne unit, namely, the 22nd reserve air regiment, which consisted of four assembly brigades and three training air squadrons (one each for "kittyhawks", "" harricains ", and" one "aerobabs"). In addition to the Lend-Lease planes, more than a million rounds of 37-mm M4 aircraft guns (eng.) Russian were delivered, which were armed with the “Airbrake” ».Thefirstpart,retrainedattheAerocobra,was153IAP,whichcompletedtrainingonJune14,1942andwasrelocatedtotheVoronezhFront,whereitarrivedonJune29.For3monthsoffighting,theregimentdestroyed18bombers,45fighters,theirownlosses-threepilots,8cars,andwasawardedtherankofGuards(28Guards.IAP).ForthefirsttimeintheGreatPatrioticWar,«Aerocobra» entered the battle May 16, 1942 as part of 19 Guards.
