Aero-News Quote of the Day

"Vibrations from launch can significantly impact the vehicle and its systems, which is why it's important to understand and mitigate those issues before we get to the pad. The SLS vibration levels on the actuators are significantly higher than the levels the shuttle experienced. We determined in the design process that the effects of the higher vibrations can be alleviated by adding stiffer springs to the actuator's mechanical feedback."
