Paper model of the P-1 reconnaissance bomber
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 P-1 Bomber Scout
In the history of this aircraft is known as the army intelligence officer P-1, copied by Russian engineers from the English "De Havilland" D.H.9. Usually people knowledgeable in the history of aviation, the importance of the machine is low.It is believed that the P-1 was only a prelude to really full-fledged combat vehicles. In the Soviet period, this opinion was not discussed, of particular interest to agitate «moss-covered»Therewasnohistory.Well,therewassuchanairplane-andtherewas,builtitbecauseoflackoffundsandexperience.Inlargewars,theP-1didnotparticipate; it had no noticeable effect on any events.
At the beginning of 1923, in accordance with plans for the development of the aviation industry, a design department (KO) was organized at GAZ No. 1, which was headed by N.N.Polikarpov. His first task was the production of D.H.9A working drawings with the engine "Liberty". Since there was an experience of building D.H.4 and a reserve of parts for thirteen D.H.9 with engines "Puma" and raquo; and hundreds - with engines "Fiat", then it was primarily about putting in order the drawing facilities and about preparing a large series. By the way, an attempt to install the motor «Liberty» on D.H.9 taken and on GAZ No. 31 in Taganrog. According to the newspaper Pravda, on May 15, 1923, such an aircraft for the first time broke away from the runway of the factory airfield.
The idea of developing a new machine based on D.H.9A arose on the initiative of the department of N.N.Polikarpov.In February 1923, D. Grigorovich was appointed the technical director of GAZ No. 1 and, accordingly, the head of the KO, who was in that capacity until August 1924. Then Polikarpov returned. Thus, both designers are involved in the creation of the aircraft, which subsequently received the designation P-1.
In the initial draft of the P-1, defined as a modified and simplified version of D.H.9A, the developers assumed with the same engine, «Liberty»toachieveimprovedflightandtechnicalcharacteristicsincomparisonwiththeEnglishprototype.TheconstructionoftheprototypeP-1wascompletedonJuly30,1924,butthebeginningoftheflighttestswasdelayed.Thereasonwasthedecisiontousetheplateradiatorsofthesystem"Lamblain",thedesignofwhichwasknownonlyfromthemagazinesandprospectusesoftheFrenchmanufacturer.Homemaderadiatorshadtoberemademanytimes,intheend,theywerebroughttotherequiredlevelbyanexperimentaltest,andtheaircraftenteredthetest.However,«Lamblaine» on Р-1 have not got accustomed, and cars were issued with frontal honeycomb radiators.
In August 1924after the tests, a statement appeared about the obsolescence of the aircraft and about the need to develop a better intelligence officer. In the future, throughout the entire period of construction, the P-1 was recognized as obsolete and requiring replacement, which, however, had little effect on the production volumes.
The first batch of 200 copies of the R-1 was ordered back in 1923. From March 15 to May 29, 1924, without waiting for the prototype tests, Plant No. 1 passed the first 25 scouts without weapons, another 7 were in the stage final assembly.
Initially, P-1 used imported Liberty » which gradually replaced the M-5. The first P-1 with the domestic engine (с / н 2654) was tested in January 1925. In March the pilot FS Rastegaev made a test flight on it on the route Moscow-Smolensk-Vitebsk-Leningrad-Moscow. This plane later received the name "Leningrad Bolshevik".
P-1 became the first Soviet aircraft produced in mass quantities. Moreover, a significant share of the issue was financed by a public subscription organized by the Society of Friends of the Air Force (ODFM). P-1 was produced for GAZ No. 1 and GAZ No. 31.
