An electromagnetic vibrator for use in flutter testing
Abstract
This paper describes a unique vibrator that can be used for the flutter testing of airplanes. The device is a variation of a linear electric motor; it uses alternating electromagnetic forces to move a magnetic mass and produce vibration. This design approach requires few components and makes the device attractively simple, reliable and efficient.
