About Energia
(short description)
source site
The heavy rocket Energia has been developed for delivering cargoes weighing about 100-110 tons to a low Earth orbit. The rocket is universal because it can deliver various cargoes in terms of their dimensions and distribution of weight.

General specifications:
Full starting weight 2419 tons
Including payload 105 tons
Overall dimensions length 60 m, max diam 18 m
Full thrust on start 3582 tf
Maximum G-factor 2.95

The rocket is grouped following the longitudinal arrangement of stages with a lateral arrangement of a payload.

First stage - block A
"block A" The first stage consists of 4 reusable rocket blocks (block A), fixed around the second stage central block in pairs.

Block A specifications:
Dry weight About 62 tons
Fuel weight 310 tons (Lox/Kerosene)
Dimensions Length 38.3 m, diam 3.9 m
pair of A-blocks
At the first stage one four-chamber engine RD-170 is mounted.
RD-170 specifications:
Thrust at sea level 740.5 tf
Thrust in vacuum 806 tf
Fuel Lox/Kerosene
Burn time 140-150 s

Second stage - block C
"block C" The second stage is a central non-reusable rocket block (block C).

Block C specifications:
Dry weight 78-86 tons
Fuel weight 704 tons (Lox/LH2)
Dimensions length 58.1 m, diam 7.7 m
At the second stage four engines RD-0120 are mounted.
RD-0120 specifications:
Thrust at sea level 147.6 tf
Thrust at vacuum 200 tf
Fuel Lox/LH2
Burn time 480-500 s
"RD-0120" engine

Ground stage - block Z
"block Z" Block Z is the intermediate module which ensures connection between the ground communications and the rocket. Block Z is reusable.

Payload variants
1. Any load weighing about 105 tons

For example, Buran. Theoretically instead of Buran any other cargo (including an oversized one) can be mounted.

The only condition is that a payload should have its own engine to perform a complete orbit insertion, as it is necessary that Energia does not give the full orbital speed to its cargo.

2. Any payload in special container equipped with an upper stage

This concept (the former name of it is Buran-T) is based on a special aerodynamic container. Basically there exist three variants:

1. Buran-T + space tug DM + payload.

Payload specifications:
PL volume is about 830 cubic meters (35 m length and 5.5 m diameter). PL weight is 88 tons being put into LEO 200 km high and 81 tons into 600 km high Earth circular orbit.

2. Buran-T + space tug Smerch + payload.

Payload specifications:
PL volume is about 550 cubic meters (23.5 m length and 5.5 m diameter). PL weight is 18-19 tons being put into a GEO orbit, 23-29 tons at the Moon Lagrange point and 21.5-23 tons into a near Moon orbit.

3. Buran-T + space tug Smerch + space tug DM + payload. It is a two stage tug system.

Payload specifications:
PL volume is about 460 cubic meters (19.5 m length and 5.5 m diameter). PL weight is 26-28 tons being put into the Mars trajectory, about 15 tons into a near Mars orbit and 5-6 tons into the Sun trajectory with a tour round the Jupiter.

DM space tug
DM space tug DM is a light transorbital space tug.

DM specifications:
Dimensions length 5.56 m, diameter 3.7 m
Thrust at vacuum 8.5 tf
Fuel N2O4/UDMH, 14-15 tons

Smerch space tug
Smerch space tug Smerch is a heavy space tug with long life time.

Smerch characteristics:
Dimensions length 16 m, diameter 5.5 m
Thrust at vacuum 10 tf
Fuel Lox/LH2, 70 tons
