Hypersonic 2 Team Air Crack HOT!
Hypersonic 2 Team Air Crack
and so they said, ok, if we move forward, well have to do so on a somewhat accelerated schedule to ensure that we learn those lessons to try to ensure that we understand how to get to the threshold of being able to make that decision. and so we went ahead with it. and now we have the operational requirements test for a flight test for a hypersonic flight demonstration as its flown on our test vehicle, and we have several test programs under way that will help us to learn. and the lessons that weve learned from the test campaign will help us to be better informed, if this future capability is put into service.
today, the air force plans to fly an x-51a waverider hypersonic vehicle on the defense departments langley air force base in virginia. theyre going to perform a series of flight tests on that for two weeks. and theyre going to try to demonstrate at least partial reentry from space, as well as high speed flight. a wavierider is basically a cruise missile that can go hypersonic in space, that can fly at hypersonic speeds and go into orbit and come back down.
tom karako: so, were looking at hypersonic, you know, from, again, the, you know, from, you know, from the perspective of, you know, fast is good, and how do we make it safe, as well, and what are some of the technologies that will make it safe? what do you mean by safe?
mike white: well, so youve got to, you know, think about, you know, there was a moment in the development of hypersonic technology, you know, that we reached a kind of a tipping point and you know, were going to have to figure out how to make this thing work. and so the core challenge was, you know, we had to have an engine that could operate at those conditions, you know, operating at mach 20 or mach 25 or whatever its operating at. and were going to need to be able to use a different kind of material for the airframe, like the skin that we need to have for the aircraft, because weve got to get the speeds up and then from a computational point of view, you know, were going to need a much faster computer because we need to simulate and do the simulation to insure that, you know, that if we have a design flaw, you know, that we can figure it out well in advance of operating the system. and so that was, you know, kind of the problem that were having.
and thats what they were doing at the test ranges both in the united states, obviously, the test ranges in utah, and in the united kingdom. and so the air force has moved forward with their glide system activities, and at the same time, im sure that they have some element of technology development and we have definitely done some of that in ways that are consistent with the national defense strategy.
and so as we look at future weapon systems, we have to recognize the vulnerabilities that we have to be able to exploit with future weapon systems and have to have some thinking about what the possibilities are relative to hypersonic.
number one, there is no magic. there is no magic that happens at mach 5.0 relative to what you had at mach 3 or mach 4. and so in terms of the technology, of the development of the technology that you are developing, there is no magic that happens at mach 5. and so the technology development is not any different at mach 5.0 than at lower supersonic speeds. and so a lot of our technology needs to be supersonic. and then we need to think about the materials and the heating and the cooling requirements of the vehicle.
i think the most obvious one in terms of the runway testing is when you try to do high mach. if you look at the side view at a mach 1 you understand how much drag you have on the aircraft. you have lots of drag. right? and if we try to do mach 2, were gong to have much more drag, right? and so you have to understand how much drag youre going to have. and, you know, when you put a lot of technology on the system and when you have a mission, what is the burn time of the system to give you that capability to put that technology on that system?
