Dream Chaser Buffet Wind Tunnel Model  The Dream Chaser model with its Atlas V launch vehicle is undergoing final preparations at the Aerospace Composite Model Development Section's workshop for buffet tests at the Transonic Dynamics Tunnel at NASA Langley. The scale model is being tested as part of NASA's Commercial Crew Development program to regain the American capability to launch astronauts safely to the International Space Station. The lifting body reusable spacecraft would carry as many as seven astronauts to the space station. Sierra Nevada Space Systems is developing the craft under a Space Act Agreement with NASA. With the help of hundreds of pressure transducers, engineers from Sierra Nevada Corporation, the United Launch Alliance and NASA Langley will look at the pressure fluctuations the model and launch vehicle stack experience during the critical ascent to orbit, especially at transonic speeds. Shock-waves form on launch vehicles as they approach the speed of sound and may result in regions of highly unsteady flow. Within these regions of the Dream Chaser and launch vehicle, the resulting buffet forces and high frequency acoustic noise must be clearly understood as part of the vehicle design process. Transonic wind-tunnel testing of large, highly instrumented scale models is the only method of determining the buffet environments of launch vehicles with complex shapes.

awesome vid Lex
thx bunches
Thanks — but I’m not Lex
- SJS
Dang,
Lex… umm… SJS, that WAS GREAT.Those guys at Boeing certainly do good work. I most definitely appreciated the “total picture” aspect of this film, with the BB-stackers, maintainers, SAR guys, et al, getting some “air time,” too.
I haven’t made up my mind if I’m gonna steal this… or not. Regardless: It’s great good stuff.
Lol, Sorry SJS, didn’t notice you were posting here.
LOL, crossed my favorite blogs. Thanks SJS.
Riight.. “there are no winners or losers here.”
Cool vid. Thanks for sharing.
This is usually playing on all of the big screen TVs in the MacDill BX. You can buy the DVD for not much money at a BX…. and probably a PX too. It is awesome on a big screen with surround sound.
