Introduction In many ways, composite materials are ideally suited to pressure vessel applications. Two main factors contribute to this suitability: The loads in a cylindrical pressure vessel are inherently anisotropic…
Introduction Filament wound composite pressure vessels are widely used in commercial and aerospace industries as high pressure containers due to their high strength and lightweight. These vessels consist of a…
Introduction As aerospace vehicles progress into the hypersonic regime, new challenges face the design engineer. Successful design of this type of vehicle clearly requires the capability to analyze high-speed aerodynamics,…
Introduction In 1973 Hough studied the slow convergence of the Vortex-Lattice Method (VLM) as the number of spanwise divisions (strips) is increased. Specifically, the lift curve slope of a lifting…
Introduction Configurations of aerospace vehicles have historically been developed in a sequential process in which the fidelity of analyses increases as the level of definition of the configuration is increased. At the earliest stages of…
Introduction With the increased interaction between the aerodynamic, structures, and controls disciplines in advanced aircraft, it is increasingly important to accurately predict the aerodynamic forces due to control surface deflection. The aerodynamic behavior of oscillating…
Introduction Some transport aircraft concepts currently being studied are extremely lightweight and flexible compared to traditional designs. The feasibility of the new concepts may depend on flight control systems to alleviate the structural loads.…
Introduction While the interaction between aerodynamic and structural phenomena have been understood for many years, most progress in accurately predicting aeroelastic interactions has been made in flight regimes where both the aerodynamics and the…
Introduction Historically, flight control laws have been designed based on the quasi-steady, mean axis flying qualities of an aircraft. However, as airplanes get larger and larger, flexibility and structural dynamics…
