Design and construction of teachers and students of the university of a series of high-speed aircraft for various purposes - a fact in the history of aviation exceptional. "In the span of aviation thoughts, courage in solving problems, built on a culture of quality aircraft designers KAI has the right to claim the first place in the Soviet Union "- he wrote in September 1934 g. "Airplane" magazine. This high score is largely due to the, that the Department of aircraft, you just created in the HAI, He led the talented designer IG. Neman. In his early thirty years behind the Niemen had an excellent school of aviation art in KB KA. Kalinin.
Under the leadership of IG. Neman in the early 1930s. planes were built HAI-1 and HAI-6. In January 1934 g. focus team is focused on the design of double-speed short-range bomber and reconnaissance CP (HAI-5). In its design successfully implemented innovative ideas, aprobirovannye to HAI-1: perfect aerodynamic design, retractable landing gear, wing, fuselage and tail with smooth plywood stressed skin. Then Neman remained true to its motto: "None of the projecting portion in the flow!"To this end, for the first time on the scout bomb suspension was removed and placed in the fuselage on the cassette holder. Also for the first time in the HAI-5 used a very successful turret MB-2 machine guns ShKAS. Spherical setting screen has an aerodynamic compensation, allowing easy rotation of the turret at high flight speeds. The embodiment was mounted fotorazvedchika fotoustanovka with RC, spent on HAI-6. Build Aircraft HAI-5 (P-10) in a batch plant, loaded aircraft production and IHT-Z and-1, It was very slow. In addition, the constantly changing terms of reference. Much had to finish and remodel, before the car came to life. And the engine M-22, projected on a plane, hopelessly outdated, and it was necessary to replace it. In March 1935 g. were purchased in France three engines Gnome-Rhone "Mistral-Major", and HAI identified one of the three. But to get it was not possible - the engines went to the CIAM and the factory number 29, where it was planned their production under the brand name M-75. spring 1936 g. IG. Neman was instructed to finalize the draft HAI-5 under the engine M-25 (Wright "Cyclone"). This decision was forced, it allows you to quickly pick up the car in the air.
In late June, 1936 g. Test Pilot BN. Kudrin made its first flight on HAI-5 (P-10). The results exceeded all expectations - the maximum speed on the scout 100 km / h higher than the speed of aircraft of this type, being armed. Quite unusually passed state tests HAI-5 in the Air Force Institute. The thing is, that at the same time the aircraft to the test went another experienced intelligence, R-9, Factory built in the Central Clinical Hospital № 1 brigade SA. Kocherigina. Comparative tests HAI-5 and P-9 spent whole group of pilots. Preference was given to the aircraft IG. Neman - the more progressive. Under the designation P-10 production aircraft launched at the Kharkov and Saratov Aviation Plant. During normal production HAI-5 (P-10) constantly improved. So, at 1938 g. rate shown on BBC Research Institute trials experienced embodiment HAI-5bis engine M-25E in 425 kmh. Part of the machines decommissioned used to Aeroflot under the name SS-5. AT 1938 g. attempts to create on the basis of P-10 ground-attack aircraft. So there were modifications HAI HAI-51 and-52. The latter was put into production. However, the sudden arrest IG. Neman and the defeat of its Bureau served as the reason for the collapse of works on the perspective planes. There were built more than 490 P-10. Recent instances scout P-10 were in service until 1943 g.
