B-24 Liberator paper bomber model

The paper model of the B-24 Liberator bomberis an American heavy bomber from the Second World War, developed by «Consolidated» (Consolidated). The most massive bomber in aviation history. Actively used in the European theater of operations.

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

Consolidated B-24 Liberator American Heavy Bomber

American heavy bomber Consolidated B-24 Liberator - American heavy bomber from the Second World War, developed by «Consolidated» (Consolidated). The most massive bomber in aviation history. Actively used in the European theater of operations.

On March 30, 1939, a contract was signed with the US Army. A prototype made the first flight December 29, 1939

A conventional fuselage design had a height that made it possible to equip a bomb bay with vertical stacking up to 3,629 kg of bombs. During the bombing when the hatches were opened, the doors along the roller guides were drawn into the fuselage. This design had a smaller frontal resistance compared to conventional bomb holes. The aircraft had a three-post retractable landing gear with a nose strut, and the powerplant included four Pratt-Whitney R-1830-33 Twin Vre engines (Pratt & Whitney R-1830-33 Twin Wasp).

Creation History

Development of the B-24 began on the order of the US Air Force in 1938. This development was part of the overall program to expand the US industrial potential for the needs of the Air Force.In January 1939, the Air Force officially issued an order (specification C-212) for the creation of a bomber project that would surpass the B-17 in all basic characteristics: range and speed of flight, and armament.

The contract for the creation of the prototype was signed in March 1939, with the prerequisite that the prototype will be fully ready before the end of the year. The creation of the prototype was fairly simple at the concept level, but in practice the work was time consuming.

In comparison with the already existing B-17, the aircraft under development was shorter and the wing area was 25% smaller. At the same time, the length of the wing was larger. Instead of the 9-cylinder Wright R-1820 engines, 14-cylinder Pratt-Whitney R-1830 engines with a capacity of 1,000 horsepower were used on the prototype. The prototype had a take-off weight of 32 tons, which was one of the best indicators of its time. In the development was applied a number of new solutions for the American aircraft industry. In particular, for the first time a three-post chassis was used, a Davis aerodynamic scheme (the arrangement of the wings is similar to flying boats). A characteristic feature was the presence of a rather long tail of the aircraft.

Bench tests in the wind tunnel showed that the aircraft has high flying performance.

The finished prototype, which received the XB-24 marking, took off on December 29, 1939. After him, in 1940, 7 more aircraft were manufactured under the marking YB-24. This was a preparation for the start of mass production.

The initial order for serial aircraft was 36 for the US Air Force, 120 for the French Air Force and 164 for the UK Air Force. Almost all the first planes built were delivered to England, including those cars that were not transferred to France due to its surrender in 1940.

The well-known name «Liberator» Originally it was given by the British, but it also took root in America and later became the official name of this type of aircraft.
