/ Hypersonic rocket stages on solid metallized fuel with a liquid oxidizer have an advantage over ramjet systems. OFLAMERON review - such systems have a much simpler design and widely use existing technologies (work with solid fuel, tanks, compressors, pressurization) - a liquid oxidizer in a capsular tank cannot in principle cause an explosion. Maximum - fire on surfaces of solid fuel) - liquid oxidizer allows the use of an incredibly efficient heavy solid propellant. Efficiency combustion (thrust) is easy to adjust if you change the speed of pumping the oxidizer through the channels in the fuel - in the conditions of hostilities, restrictions on the supply of technologies and components, such hypersonic systems much easier to produce in required quantities than systems with ramjet engines - hypersonic rocket stages on solid metallized fuel with a liquid oxidizer do not depend on supplies external oxidizer (atmospheric oxygen) and can overcome missile defense at high altitudes - 50-70-100 kilometers - the absence of problems with the calculations of the inlet air circuit allows the use of much higher speeds - 15-25 M - here, ultra-high values of hypersound will have less effect on the conditions of fuel combustion, tk. rocket fuel oxidation conditions less dependent on external conditions. No need to lengthen the motor - movement at altitudes greater than 70 kilometers does not cause strong heating at speeds of 15-20M and the problem of heating will occur only on a short path of fall through the atmosphere, when the amount of oxidizer will be minimal /
