D-6 - Propellant

Work on the creation of solid propellant SLBM development fuels were conducted in two main directions: ballistic fuel "Nylon-B (developed by NII-125) on the basis of artillery gunpowders and composite solid fuels Nylon (GIPH developer). Solid composite fuel Nylon was created using ammonium perchlorate, furfurolno-aceton resin, tiokola mark "T" and nitroguanidina, and for its production was supposed to create specialized enterprise. On the basis of both fuel types was developed by 7 options, two rocket fuel "Nylon-B" five "Nylon". According to the project of "Nylon" developed five versions of missiles: NIR-1, NIR 2 NIR NIR-3 c-4B, 5B, NIR was later developed two more variants of the NIR-6C and 7C NIR. Project Nylon-B rocket was created with pressure in the engine of the first stage of 40 kg/sq. cm, single-pulse engine 200 kg sec/kg. The diameter of the primary and secondary engines was 0.7-0.85 meters, each stage included four engine, linked together in one package. To drive steering nozzle attachments applied steering hydraulic machines. The chassis was designed using material PT-912.

The first versions of the missile would be used to test the gas controls, but, when tested, they burned and subsequent variants of the missile were studied with pivoting nozzles engines but and this direction received development. The latest versions were designed with controllable nozzles at the nozzles (nozzles, cutting material-fibreglass and molybdenum, chrome), but the real embodiment of this construction management bodies appeared only on BR 8 k 98 and 8 k 96. To drive steering nozzle attachments applied steering hydraulic machines. In November 1959 the draft project, was completed in 1958-1962 years of anticipated conduct of OCD, the beginning of flight tests scheduled for the year 1960.

In the course of work on the topic of E-6 solid propellant composition, GIPH developed various charges. CDB-7 together with the plant No. 7 and GIPH developed three models of designs engines with a mass charge in 1 kg-10 kg for the first version-the second option and 500 kg-third charge that received designations: mill-and 1-293, mill-and 1-295, f-40-182, etc. Production of 1 and 10 kg engine options were carried out at the second plant, GIPH engines 500 kg were Shop No. 8 plant named after Morozov. Single pulse these SRBS was in the range from 220-230.

At the Rzhevskom test site near Leningrad under the topic D-6 conducted practicing experienced solid propellant Motors weighing up to 0.5 t rocket "with" used composite solid fuels "Nylon" (GIPH developer): IPA-SA-1-27-l-2 or NLA-p 4-125-22-l. The pressure of the engine of the first stage was to compile a 40 kg/sq. cm, single impulse engine 210 kg sec/kg.

Inertial control system designed in NII-592. In the course of the works were created layouts-compartments 1 instrument-MS and 1-MA.

By the end of the year 1959, using preliminary data obtained from the head performers complex, TSKB-16 has developed a draft project 629 D6 (Chief Designer I.E. Evgrafov) placement project 629 submarine missile complex D-6. It when you save a number of missiles, equal on the submarine project 629 and, provided the changes associated with the specifics of the new complex. Expected to apply new starter installed, new equipment and missile maintenance management systems, change the design. composition of ship systems and devices.
