Russia is one of the first places among the countries developing materials for hypersonic flight, also Russian scientists actively trying to resolve other challenges facing the designers, RIA Novosti reported with reference to the Foundation for advanced studies.
“The material must withstand a temperature of fifteen thousand degrees or more, and for a long time. Conventional materials including high strength steel, at this temperature, the melt, however, today there are relevant developments in the field of composite materials based on carbon fibers. In this area significant results have been achieved, and Russia is one of the first places in the world to develop such materials”, — stated in the message.
However, apart from the search for new materials, scientists need to solve some other tasks. Thus, the aircraft must be managed at an altitude of 30-50 kilometers in highly rarefied air, we are talking about a rapid flight “incandescent” object when classical control methods are not physically working.
“The third task is to create the engine of the new type. Today there are no engines that can long operate at supersonic speeds — at least it’s not serial aircraft engines on hydrocarbons. 20 years ago, Russia had its own developments in this field, and this heritage is today actively studied and used,” added the Fund.
The fourth challenge is ensuring the electronics work or location of passengers within a hypersonic aircraft. When the surface temperature of the 1.5 thousand degrees the cooling system needs to create in a more or less “human” climate: it requires a huge power supply system and its sustainable operation, says FPI.
“The fifth objective is to provide a hypersonic aircraft contact with the dispatcher. At high speed the apparatus is surrounded by a plasma “cocoon”, which does not allow radio waves to penetrate neither in nor out. Cocoon creates a kind of screen, plasma cell, so the antennas have to be placed either in the tail of the apparatus, or to use the plasma as a conductor, turning in the antenna itself”, — summed up in the Fund.
As noted in the Fund, in case of success in the development of hypersonic technology, it will be possible to transport people or small cargo from Europe to America and back again in less than an hour. In addition, hypersonic technology could be used in the field of space tourism, providing flight passengers with the earth’s surface to orbit and back.
The Foundation for advanced studies was created in 2012 to promote research and development in the interests of defence and security of the country. Activities are conducted in three main areas — chemical-biological and medical, physics and technical, information. At the end of 2015 in the structure of FPI was created by the national center of technology development and the basic elements of robotics. Currently, the Foundation runs more than 50 projects, they created more than 40 laboratories in leading universities, research institutes and defense industries.
