Difficulties in making the fastest aircraft in the world

Picture I  http://crisisofdemocracticstates.blogspot.com/p/difficulties-in-making-fastest-aircraft.html Kimmo Huosionmaa SR-71 "Blackbird" is the fastest known aircraft in the world. Making ultra-fast aircraft is not easy, because the heat in the atmospheric fly is very high, and that's why that very fast aircraft must rise above the tight layers of the atmosphere. The friction is the very bad problem, and that's why those aircraft must equip with the carbon fiber core, what would stand the extreme heat and pressure without melting. But the raise above the tight layers of the air would cause the problems because the jet motors cannot get enough air, and that's why the power of those machines would decrease. One solution would pump the oxygen to the turbines from the liquid oxygen tanks, but that would cause decreasing the payload of that aircraft. And also oxygen tanks would decrease the flight time. So there must create the solution, what allows the m...

Lockheed XQM-60 "Kingfisher" the early version of hypersonic cruise missiles

Lockheed XQM-60 "Kingfisher" (Picture I) http://crisisofdemocracticstates.blogspot.fi/p/lockheed-xqm-60-kingfisher-early.html Kimmo Huosionmaa I found an article at Internet or Wikipedia, where was told a story of XQM-60 "Kingfisher" target drone, what had the capacity to speed of mach 4,3. This ramjet- propelled drone was in operational in 1951, and this thing was meant that the United States Air Force had the capacity to make hypersonic cruise missiles in 1950's. In this drone had the same capacity to strike targets than some Tomahawk cruise missile. This kind of drones was officially made for anti-ballistic missile simulations, but there are so many details in this drones history, that I think the real purpose of that project was creating the very fast missile, what had the capacity to destroy targets by using kinetic energy. That means that "Kingfisher" might use as the model to create those extreme powerful missiles, what have the ca...
