In addition to giving a basic review of the existing techniques for helicopter mobility testing, this paper goes on to present some recent formulations and techniques for efficient measurement of structural dynamic characteristics of the helicopter during ground vibration testing. For single point shaking, a new method for calculating the transfer mobility between excitation and response coordinates which results in substantial saving in testing duration, while assuring acceptable accuracy is described and test results using this method are presented and compared with existing methods. The formulation for extending this method to multiple shaker testing is also presented.
