Paper model of the Yak-3 fighter
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;
- 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;
- 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
Soviet single-engine fighter Yak-7b
Soviet single-engine fighter Yak-7b - Soviet single-engine fighter aircraft. The Yak-3 aircraft was created in 1943 by a team headed by A. S. Yakovlev, developing the Yak-1M fighter that had already justified itself in battle.From its predecessor the Yak-3 had a smaller wing (its area is 14.85 square meters instead of 17.15) with the same fuselage dimensions and a number of aerodynamic and structural improvements. The oil cooler, located earlier under the VK-105PF2 engine, was transferred to the wing, and its air intake was abolished and replaced by the inlet holes in the nose of the wing. The weight of the empty Yak-3 was only 2105 kg, the take-off - 2650 kg.
It was one of the lightest fighters in the world during the first half of the forties. High speed (more than 650 km / h with VK-105PF2 engine and 720-740 km / h with VK-107 and VK-108 engines), excellent speed-up (set time 5000 m - 4.1 min, good ceiling (11 800 m) ) and maneuverability, the simplicity in piloting made the Yak-3 a favorite fighter plane.The Yak-3 design embodied the experience of the team that had already created a number of excellent combat vehicles and the advice of the pilots who fought on them, the achievements of the industry that gave the designers materials , allowed to design the machine with a wing load close to 180 kg / m2. The Air Force Research Institute noted that the Yak-3 with the VK-107A engine "... on the basic flight-technical data in the range of heights from the ground to the practical ceiling is the best known domestic and foreign fighters." The factories built 4848 Yak-3 aircraft.
