The Airbus Perlan Mission II has reached another major milestone, the Ground Vibration Test (GVT) of the Perlan 2 Glider. The testing is taking place this week at ATA Engineering, in San Diego, CA.
Ground vibration testing is often performed on experimental aircraft. It applies controlled vibration to the structure and then measures how the aricraft responds. Excessive vibration can cause a variety of problems in a aircraft.
