Energy of triumph
In 1975-1977 in the process of creating launch vehicles of the super-heavy class “Energy” and the middle class “Zenith”, research was conducted on the creation of a launch vehicle of an intermediate (heavy) class with a payload 30-60 t.
The initial version of such a launch vehicle was the Thunderstorm launch vehicle (RLA-125), consisting of central and two side blocks from the Energia launch vehicle. In 1976, a technical proposal for the Thunderstorm was developed, and in 1977, an addendum to it was developed.
In 1985, in accordance with the Decree of 25 December 1984, a draft project was released showing the fundamental possibility of creating a launch vehicle of a heavy class Thunderstorm at X-NUMX production and technological base with a low orbit carrying capacity to 63 t.
According to the decision of the NTS of the Ministry of General Machinery of 18 in August 1988, NPO Energia was instructed to clarify the conceptual design for the Thunderstorm launch vehicle (RLA-125) taking into account the launch of spacecraft in the interests of science, the national economy and the Ministry of Defense with 25 tons to 40 t in low orbits.
In 1989, an addition to the draft design of the Thunderstorm launch vehicle was issued, which proposed using not four RD-0120 engines on the central unit, but two with a corresponding reduction in the size of the central unit, and also considered variants of the launch vehicle 27 t to 50 t, including using the winged reusable block 1 steps.
Further development of the heavy-class booster ended with the release in 1990 of the draft design of the launch vehicle, tentatively called Neutron (order of 28 from December 1989 from December General Designer), which was approved by the 19 General Designers Council in July 1990.
The launch vehicle received the official name "Energy-M". In the same year, a full-sized model of the rocket was manufactured and installed at the launch position.
8 April 1991 was issued a Resolution on the creation of a heavy-class launch vehicle on a competitive basis. The competition was attended by the NPO Energia, the NPO Yuzhnoye (S.N. Konyukhov) and the Salyut Design Bureau D.A. Polukhin). 6 July 1991. The collegium and the presidium of the NTS Minobchemash decided on the feasibility of developing and building a heavy-class carrier rocket Energia-M.
The development of baseline data and technical specifications for components of the Energia-M launch vehicle began in the same year 1991.
1991 to 1993 design documentation was developed and production was prepared for the production of a launch vehicle. In 1993, coordination was completed and tactical and technical tasks were issued for the development of the Energia-M carrier rocket, approved by the General Director of the RCA, Yu.N. Koptev, and coordinated with the commander of the VKS Defense Ministry of the Russian Federation VL Ivanov.
The two-stage launch vehicle Energia-M is the base for three-stage modifications, differing in the types of overclocking units used.
The launch vehicle is made according to a package scheme with parallel arrangement of steps in which two rocket oxygen-hydrocarbon blocks 1 steps, borrowed from the Energia launch vehicle, are located around the central oxygen-hydrogen block 2 steps, developed on the basis of a similar unit of the launch vehicle "Energy".
On the central unit there is one RD-0120 engine, which is launched on Earth with advance over the RD-170 1 engines of the stage.
The package of rocket blocks is installed on the launch-docking block (block I), borrowed from the Energia launch vehicle, which serves to provide power, pneumatic, hydraulic and electrical connections of the launch vehicle to the launch vehicle in preparation for launch and is a reference element during assembly, transportation and installation of the launch vehicle on the launcher.
The payload is placed in the cargo compartment of the 2 unit and is mechanically connected to either the transfer compartment (in a two-stage version) or the booster unit (in a three-stage version).
The control and stabilization of the launch vehicle in the active part of the flight is carried out by deflecting the thrust vector of the 1 and 2 engines in two planes using the steering gear system, while the 1 stage oscillates in four planes of four combustion chambers of each engine, and on the 2 stage rotates the engine also in two planes, and for roll control, special roll units operating on gas taken from the 2 stage propulsion system are used.
The proposed configuration of the launch vehicle Energia-M, unlike all existing missiles, provides for mounting side blocks in the upper link belt on the cargo compartment of the central unit, which makes it possible, by reducing the length of the missile, to reduce the level of loads on the modular parts of the side blocks to the level of loads for a rocket carrier "Energy", to abandon the special support device (simulators of the two side blocks), as well as to increase the mass of the payload due to the separation of the upper belt of power links with the cargo compartment.
The booster "Energy-M" was created with the maximum borrowing of blocks, systems and units that have passed experimental and ground testing as part of the launch vehicles "Zenit" and "Energy", including the use of high-energy fuel - liquid hydrogen, and its operation was provided for starting constructions and from the technical complex of the carrier rocket "Energy".
The use of the material part of the Energia launch vehicle for the Energiya-M launch vehicle will require 5-6 times lower costs than creating a new environmentally friendly launch vehicle of the same payload.
A comparison of the characteristics of the Energia-M launch vehicle and foreign launch vehicles shows that, in terms of size and energy capabilities, the Energia-M launch vehicle is at the level of the most powerful launch vehicles, Arian-5 and Titan-4, exceeding them in mass and size of output payload, that its specific characteristics are at the level of the best characteristics of foreign launch vehicles, that it is an environmentally safe system compared to foreign launch vehicles, as it does not use high toxicity GOVERNMENTAL fuel components or solid-fuel engines and that the estimated cost of its launch will be below the cost of start-up of foreign missiles.
The launch of the Energia-M launch vehicle is justified by the stable area of its use, justified by the existing trends in the development of spacecraft.
The analysis of research programs, national economic and space activities and the tasks of the Ministry of Defense with 1992 to 2005, the characteristics of spacecraft involved in these programs, as well as the characteristics of foreign spacecraft shows a trend of increasing their masses and dimensions. So, by 2005, the spacecraft mass can increase to 6 t in geostationary and up to 23 t in highly elliptical orbits. Removal of such spacecraft with increased mass is provided by the Energia-M launch vehicle.
Analysis of currently developed payloads shows that among them there are those characterized by the impossibility of creating a dense layout under the fairing of the launch vehicle at the launch site. These are primarily payloads intended for the creation of large-size structures in space, coherent spacecraft with several spatially separated antennas or spacecraft with single large antennas. The booster "Energy-M", having increased the size of the zone of the payload and, accordingly, the fairing, also provides the removal of such payloads.
Currently, group spacecraft launch is widely used, which is implemented on domestic Cyclone and Cosmos launch vehicles, on foreign launch vehicles Ariane-4 and Titan-3 and planned for Ariane-5 launch vehicles ", H-2," Great March-3 ", as well as on the booster rocket" Energy-M ". This method of launching reduces the cost of launching spacecraft by replacing several launches of smaller launch vehicles with one launch of a larger launching vehicle; creates more favorable conditions for national economic activities in the areas of exclusion by reducing the multiplicity and total duration of the launch restrictions in these areas, and also expands the range of launch vehicles, making them more competitive in the market for launch vehicles.
The implementation of the development of the launch vehicle Energia-M will allow the solution of target tasks in the interests of the national economy, science and defense (the removal of heavy satellites of communication systems, modules of space stations, etc.); in the near future, to replace the Proton launch vehicle on highly toxic fuel components, the use of which leads to exclusion of alienated lands from the national economy and represents a great potential environmental threat both in the event of a launch vehicle accident, and during transportation and storage of fuel components, and also to keep the created complex of the launch vehicle "Energy" in working condition.
Being the only carrier rocket using environmentally friendly components of fuel and having a relatively low launch cost, the Energia-M launch vehicle will have a high competitiveness on the international market compared to existing and developed foreign launch vehicles Titan-4 "(USA), Arian-5" (ESA), "H-2" (Japan), etc.
Further development of the Energia-M launch vehicle is possible in the direction of its use for launching a small multi-purpose orbital spacecraft designed for transport and technological work during the servicing of orbital stations, as well as using reusable 1 units in its composition that are returned to the launch site. eliminates the need for land alienation for the areas where they fall.
Unfortunately, in 1995, the pace of development of a launch vehicle has dramatically decreased. Funding work has been suspended.
