Hypersonic 2 Team Air Crack
mike white: so, you know, youve got to figure out how to do all of that, and that was the core challenge. and then, you know, there were two big avenues of development that were kind of developing. and weve got, you know, for a while weve been developing the concept of using a different kind of airframe to deal with the high-mach environment, and then we were developing a different kind of engine. and then there were two different groups, or two different kind of development groups, that were working on that. and then, you know, we were going through the launch sequence, and the way were doing this was we were going to be developing a hypersonic glide vehicle first, so that we could get the technology tested and vetted. and we had to really sort of, you know, figure out how to do that with not a lot of people, and not with a lot of money, and not with a lot of time.
tom karako: right. im trying to kind of put it in perspective of the scale of this, where were talking about hypersonic, you know, what are some of the things that might be applicable to more conventional cruise missiles?
the scramjet engine essentially transforms heat energy into a form of propulsion. the engine typically has only one engine and one nozzle, as a result, both sides of the craft must share the same heat load. the first flight of the hypersonic vehicle was accomplished by the us air force’s x-51a program in october 2012.
the team worked on a hybrid propulsion system to help meet that thermal challenge.the engine would shoot a stream of hot gas outward to provide thrust. this was expected to be only temporary, however, as the high temperatures generated by the engine would burn away the outer layer of the vehicle. using a combination of 3d printed and traditional materials, the researchers designed a device that would allow the vehicle to fly for a short time in a conventional mode with a traditional, more manageable engine.
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?
