Space Aircraft Engine Engineered in Russia
October 10, 2015 13:47

The Serpukhov branch of the Military Academy of Strategic Missile Forces has created an engine for the would-be space aircraft, which is designed for both civic life and armed forces of the RF.
The combined air and rocket engine with a straight-flow intermittent combustion chamber, a stilling section and an air starting system has been engineered for providing the possibility for the propulsion system work both in the atmosphere, and the outer space. A vehicle with such an engine can deliver freights to space stations with less expenses.
"Solved is the task of creating a compound propulsion system of the space aircraft for switching the engine from air operating mode when flying in the atmosphere to the rocket mode in the outer space" — a representative of the academy explained at the exhibition Day of Innovations of the RF Defence Ministry 2015.
According to him, the principle of work is as follows: "The space aircraft patrols air area, takes off from a usual airfield, receives a command on its mission in the space, attains the outer space, carries out its mission there and comes back to the atmosphere".
The expert pointed out that there is no such a space aircraft yet, since the engine was the priority. Now the vehicle is going to be engineered. "This model project was dispatched to the leading Russian institutions in the field of space exploration, and we got appropriate comments and observations. Two plants have already undertaken to make a full-scale prototype model".
The engine utilizes kerosene fuel in the air mode, and methane and gaseous oxygen in the outer space. So far there is no target of engineering such an engine using environmentally friendly fuel, since the would-be space aircraft is reusable and will not cause problems with spent rocket stages, which ordinary space rockets do pose.
According to preliminary estimates of the Academy, the innovative engine will cost 90 million rubles whereas liquid rocket engines for one-stage rockets cost about 120-140 million. Thus, the space aircraft engine turns to be much more viable due to its cost as such, and its multiple use, the scientists emphasize.
