HBK'S TECHNOLOGY HELPS NASA TO SUCCEED


NASA’S X-57 MAXWELL GROUND VIBRATION TESTING

 

Dear Mr. LIMBERGER,

 

It’s not only automobiles that are going electric – aircrafts are as well! To
prove that aircraft can be electrically powered, enabling lower energy
consumption, emissions, and noise, NASA has developed the X-57 Maxwell. It is
the first all-electric X-plane!
 

To ensure safe flight operations, NASA built a model of the aircraft to simulate
the loads the aircraft would be subjected to during a real flight using ground
vibration tests. Learn how our accelerometers,  LAN-XI data acquisition system,
and BK Connect® software helped NASA analyze data from 191 test runs using 14
different test configurations.

HBK Expert Talk


OPERATIONAL MODAL ANALYSIS

Operational Modal Analysis conducts a modal analysis without knowing and/or
controlling the input excitation. The new HBK Expert Talk takes you behind the
scenes of the Instituto de Aeronáutica e Espaço. We will discuss and perform a
complete OMA measurement on a helicopter blade together with OMA expert
Professor Dr. Edilson Camargo.

Identifying Sources


WHAT IS SOURCE PATH CONTRIBUTION?

Is it the source that is too loud, or the path that transmits it too easily?
Source Path Contribution (SPC) analysis is a technique for evaluating noise
contributions from suspected sound or vibration sources through various acoustic
or vibroacoustic paths to the desired receiver location. HBK's SPC solution
covers both interior NVH and exterior noise.
