Wing amplifier

Without going into unimportant details, we were entrusted with the study and development of an amplifier designed to project sounds onto the wings in flight.

The goal of this European project is to verify that the wing’s penetration into the airflow can be improved by increasing high-frequency vibrations at the leading edge. Facilitating penetration means reducing power consumption!

The complexity of the project stems from the power supply voltages, which can be either 28 V DC or 115 V 400 Hertz. 230 V mains voltage will also be accepted for ground tests.

Another challenge: the device must operate at both -40 and +70 degrees, and at an altitude of 50,000 feet. The device operates in Class D, meaning it amplifies audio signals digitally.
