The picture shows 56 years old NASA wind tunnel rocket which is capable of generating winds up to 900 miles per hour.
The transonic Dynamics Tunnel has hosted hundreds of NASA projects in their history. It is recently working on its latest project. This latest guest of NASA projects is a 10 -foot long space model and termed as the most powerful rocket so far. It is called, the space launch system (SLS).
SLS is designed to send Orion spacecraft to an asteroid and other celestial space destinations on its voyage from Earth to Mars. It is expected to open new possibilities for robotics engineering and Robotics science mission to other planets like Saturn and Jupiter.
The space Engineer at NASA research center is now busy testing the model to understand the functioning and performance of the rocket during its deep space mission. This mission is considered as one of the most important and difficult missions of NASA. The tests are particularly focused to understand the cargo version of the heavy-lift block 1B SLS rocket. The SLS is capable of lifting 105 metric tonnes which are just equal to the supersonic level.
The SLS rocket scientist Mr Dave Paitak told media, “The shock waves begin just below the Supersonic level. It forms an oscillating frequency on the rocket and the vehicle itself.”
Dave Paitak later explained his line by comparing the Supersonic oscillating frequencies to that of the winds on a road trip. According to the scientist, rocket is like your hand. Just imagine spreading out your hand out of the window while traveling down the highway at 70 mph on a perfect day. Finger speed increases you will struggle to hold your hand still.
Rockets are exactly the same. Even they experience a similar type of buffeting effect. Only the speed is above 800 mph. Now you can well understand how rocket may behave when hit by and studying wind and pressure. The scientists are trying to overcome this effect.
