Abstract:In this paper the results of the numerical stress analysis of the power turbine of helicopter engine were presented. In order to solve the problem, the nonlinear finite element method was used. The numerical models of both the blade and the disc segment were made using the MSC-Patran program. In the analysis the thermal load resulting from non-uniform temperature field was defined. The centrifugal force resulting from the rotation of the engine rotor was also considered. The cyclic symmetry boundary condition … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
