Russian Launch Vehicles and their Spacecraft: Thoughts & News

Russian specialists were able to significantly increase the efficiency of rocket engines...
The result of the study showed that copper increases the burning rate of fuel by 500%, zinc - by 130%, and boron - by 10%....



Russian experts from NUST “MISiS” learned to increase the speed of missiles by adding copper to the fuel composition. As part of the tests, scientists were convinced that the copper nanoparticles in the fuel will significantly increase the efficiency (efficiency) of rocket engines.

For some time, scientists studied the effects of nano- and microadditives of aluminum, boron, zinc, nickel, copper and molybdenum on the burning rate of solid fuels. As a result, each of the additives showed a different rate of catalytic activity. For example, boron increased the burning rate of fuel by only 10%, and copper - by 500%.

As you know, at present, the so-called cyclic nitramines are used as combustible material in solid rocket fuel. However, these substances are quite resistant to the action of existing catalysts, which imposes a restriction on the burning rate of the fuel and, as a consequence, on the speed of the object. The search for new combustion catalysts for various types of jet fuel is a key task.

Researchers have proposed an alternative component composition of solid fuels. As a fuel, experts used aluminum powder, a catalyst - nano- and microadditives of aluminum, boron, zinc, nickel, copper, molybdenum and their oxides. It turned out that the addition of copper nanoparticles to fuel would increase the speed of rockets by a factor of five. The result of the study showed that copper increases the burning rate of fuel by 500%, zinc - by 130%, and boron - by 10%....

“Copper is a traditional catalyst. It is particularly active in combustion processes. However, until now it was not clear how copper nanopowder affects the combustion process of jet fuel, ”commented Alexander Gromov, the main author of the development, professor of NUST“ MISiS ”

And how do they plan on equipping the crew capsule with sufficient radiation shielding whth a 27 ton limit to the weight of the entire payload?

MOSCOW, August 14. / TASS /. Heavy launch vehicle "Angara-A5" was sent to the Plesetsk cosmodrome from the territory of the Center. M.V. Khrunicheva. A source in the rocket and space industry told TASS about this.

"The railway train with the Angara-A5 heavy launch vehicle left the territory of the Khrunichev Center for the Plesetsk cosmodrome. The rocket should arrive at the northern cosmodrome to prepare for flight tests on August 17," the agency's source said.

Earlier, Roskosmos reported that the Angara universal rocket modules were loaded into special wagons and were awaiting the decision of the State Commission to send them to the cosmodrome. As specified in the state corporation, the rocket has successfully passed the checks of the control and test station of the Khrunichev Center and is ready to resume flight and space tests.

At the end of May, the head of Roscosmos Dmitry Rogozin announced that flight tests of the Angara-A5 heavy-class launch vehicle could resume in the fall of 2020.

Angara is a family of Russian launch vehicles ranging from light to heavy classes. The new family uses environmentally friendly fuel components. The first and so far the only launch of the heavy Angara-A5 was performed in December 2014.
