141 Posted January 16, 2016 #1 Share Posted January 16, 2016 Canadian industrial designer Charles Bombardier generated quite a buzz upon unveiling the Skreemr—a supersonic transport concept designed to shuttle commercial passengers between continents at Mach 10. But despite its appeal, the notion had a few shortcomings—most pressingly the imagined craft’s inability to mitigate the resulting sonic boom, as well as the heat that would accumulate on its nose and wings upon rapidly accelerating. “I am not sure the materials able to withstand the heat, pressure, and structural stress for this application have been invented yet,” he confessed in an earlier interview. http://www.msn.com/e...gqnq?li=AAaWeYc OMG... 3 Link to comment Share on other sites More sharing options...

Goodnite Posted January 16, 2016 #5 Share Posted January 16, 2016 I think the military already have aircraft capable of such speeds but the design and materials are kept classified. 2 Link to comment Share on other sites More sharing options...
Grey Area Posted January 16, 2016 #6 Share Posted January 16, 2016 i have a question for all those who know much about space travel ....if they can go to the Moon with Spacecrafts why is this guy saying this : “I am not sure the materials able to withstand the heat, pressure, and structural stress for this application have been invented yet,” he confessed I think because the proposed model accelerates the craft to hypersonic speed in the lower atmosphere. The atmosphere is gas, at high speed traveling through a gas becomes more like fluid dynamics. When an object travels at high speed the gasses that are impacted become compressed which causes heat (this is the fireball effect we see with meteorites and spacecraft re entry). The shuttle is the best example of a reusable craft able to withstand similar effects, but after each flight the shuttle would require months of service as the ceramic ablative surface would need replacing. I would however be more concerned over the effects of high g acceleration on the passengers than any of the structural hurdles, those can be solved, unfortunately people are a different hurdle. Most of the major aerospace companies have theoretical hypersonic projects going on. It's. A very exciting subject. 3 Link to comment Share on other sites More sharing options...
toast Posted January 16, 2016 #7 Share Posted January 16, 2016 i have a question for all those who know much about space travel ....if they can go to the Moon with Spacecrafts why is this guy saying this : “I am not sure the materials able to withstand the heat, pressure, and structural stress for this application have been invented yet,” he confessed The heat and pressure are caused by atmospheric drag and space crafts do not reach Mach10 in the lower atmosphere. The Space Shuttles, for example, reduced their engine thrust level down to 67% after around 50 seconds into the flight and short b4 passing the sound barrier to reduce the dynamic pressure to the space crafts structure. After passing the barrier of sound and being in the higher atmosphere, so less drag, the engine thrust level was increased to 100% again. 2 Link to comment Share on other sites More sharing options...
141 Posted January 16, 2016 Author #8 Share Posted January 16, 2016 thanx for the answers so far ...i was just wondering about the materials used for space crafts ...couldn't the same materials be used for this project in question ? but i think Grey Area explained ...

Taun Posted January 16, 2016 #9 Share Posted January 16, 2016 Why on earth would I want to fly to Dubai?.. Now, if they can make it so that I can use the cross town expressway at rush hour in 22 minutes, THAT would be truly impressive! 6 Link to comment Share on other sites More sharing options...
Mark One Posted January 16, 2016 #10 Share Posted January 16, 2016 Good topic Ya Amar. Im in the "we already have aircraft that act like UFOs" boat. Maybe these new developments are designed to later on - trickle into society amazing new flying machines? 2 Link to comment Share on other sites More sharing options...

141 Posted January 16, 2016 Author #12 Share Posted January 16, 2016 i agree with Grey Area though , imagine the effect on ppl ? your Brain would still be in NY while your Body is in Dubai lol ...pick up your brain on Belt number 12 ...i dunno hhhhh then again it would be cool 1 Link to comment Share on other sites More sharing options...

Timothy Posted February 1, 2016 #25 Share Posted February 1, 2016 I wonder what size creator would this jet make, if crashed at the speed of 13,000 mph In reality, there would be no crater! This aircraft is proposed to reach Mach 24 at 40,000 ft. It would disintegrate at that speed/altitude with anything more than a minor vibration. For example: The highest performance business jet is currently the Cessna Citation X, which can cruise at a maximum speed of Mach .935 with a service ceiling of 51,000 ft. There is just too much air (density) at 40,000 ft for anything to go close to that fast with the current knowledge of physics. It would have to at least be at a much higher altitude. Also, a 6,000 ft runway is extremely short (shorter than the runways of probably 99% of international aerodromes). The space shuttle uses (from Wiki) one of the longest runways in the world, at 4,572 m (15,000 ft). I know not really comparable, but if they want to glide this thing to the ground, there are at least a few similarities. So I struggle to see how this guy will ever get past the concept. There is just too much 'imagined' technology here to be in any way viable in our lifetime. 2 Link to comment Share on other sites More sharing options...
