Aeroelastic Calculations of a Business Jet configuration Using the USTSD Code

Mode
	      ShapeThis report documents the evaluation of the aeroelastic analysis capability of the Unsteady Transonic Small-Disturbance code (USTSD) applied to a business jet configuration. In USTSD, the solution to the transonic small-disturbance equation is calculated in the frequency domain. Pressure distributions, lift, drag, and pitching moment coefficients are calculated and compared with available data. With a 2D boundary layer analysis included, the finite-difference solution of the non-conservative TSD equation tends to provide better correlation with data as compared with the conservative formulation in steady flow. In flutter analysis, the non-conservative formulation generated a higher flutter speed than the conservative formulation.

Development of a Dynamic Aircaft Seat Analysis Capability

Hybrid-II ATDThe development of a dynamic aircraft seat analysis is presented in this paper. This analytical model is a nonlinear finite element model composed of a seat frame and cushion, restraint system, glare shield and a rigid body model of a 50th percentile Hybrid-II anthropomorphic test dummy (ATD) occupant. Results from this analytical model are correlated with empirical results obtained during a full-scale dynamic test. The analysis is representative of the dynamic test.

Laminate Design for Coupled Wind Turbine Blades.

Laminate CouplingThe purpose of this paper is to demonstrate the effect of coupling at the laminate level on coupling at the structural level. Four extension-shear coupled laminates are examined. The laminates are then used in structures with circular, square and airfoil cross-sections. The properties of those cross-sections are used to describe a general elastic beam using a method from Kosmatka. The coupling properties of the beam are compared with those of the laminate using a normalized coupling coefficient, stiffness coupling ratio and compliance coupling ratio. The normalized compliance ratio compared well between the laminate and the cross-sections for all cases.

Postbuckling Analysis of a Wind Turbine Blade Substructure

First Buckling ModePostbuckling analysis of composite laminates representative of wind turbine blade substructures, utilizing the commercial finite element software ANSYS, is presented in this paper. The procedure was validated against an existing postbuckling analysis. Three shell element formulations, SHELL91, SHELL99 and SHELL181, were examined. It was found that the SHELL181 element with reduced integration should be used to avoid shear locking. The validated procedure was used to examine the variation of the buckling behavior, including postbuckling, with lamination schedule of a laminate representative of a wind turbine blade shear web. This analysis was correlated with data from a static test. A 100% postbuckling reserve in a composite structure representative of a shear web was quantified through test and analysis. The buckling behavior of the shear web was improved by modifying the lamination schedule to increase the web bending stifness. Modifications that improved the buckling load of the structure did not always equate to improvements in the postbuckling reserve.
