Alternating strain measurements on model and real turbine blades
Abstract
Procedures for measuring natural frequencies and dynamical stresses in axial turbine blades under operating conditions are described. The design of a new family of low-pressure blades involving measurement of dynamic stresses in model and real blades is illustrated.
