Ground vibration testing of NASA’s X-57 Maxwell electric aircraft


Electric propulsion is spawning aircraft with diverse and novel configurations. The multiple motors, rotors, propellers and fans associated with distributed electric propulsion are shaping many complex and unusual forms in the quest to enhance lift and thrust, and to reduce drag through close aerodynamic coupling with airframes.
One of the most important processes in their development is ensuring that they don’t suffer from damaging vibration. To that end, NASA has used equipment from Hottinger Bruel & Kjær (HBK) to collect and process accelerometer data in ground vibration testing (GVT) for its X-57 Maxwell aircraft. More…

Purchase support for Québec school buses

blue-bird-re-electric-bus-elektrobus-school-bus-01The Canada Infrastructure Bank (CIB) has just signed an agreement with the Bus Carriers Federation (Federation) to invest up to $400 million to enable the purchase of 4,000 zero-emission school buses (ZEBs). The CIB’s long-term investment will cover the higher upfront capital costs of ZEBs compared to diesel buses. The expectation is that the direct […] More…
