Abstract:

A representative tail boom of the UH-1B helicopter is modeled for dynamic structural analysis by the NASTRAN computer program. The finite-element model employs beam and plate elements to construct the structural model, which will subsequently be used to study the effects of simulated nuclear detonations, subjecting the model to blast overpressure exposure with and without thermal effects. The lower mode shapes and frequencies of the structural model are generated and presented as a validation check.
