Structures performance, benefit, cost-study [PDF]

open access: yes
New technology concepts and structural analysis development needs which could lead to improved life cycle cost for future high-bypass turbofans were studied. The NASA-GE energy efficient engine technology is used as a base to assess the concept benefits.

Water waves generated by the translatory and oscillatory surface disturbance [PDF]

open access: yes, 1957
The problem under consideration is that of two-dimensional gravity waves in water generated by a surface disturbance which oscillates with frequency Ω/2π and moves with constant rectilinear velocity U over the free water surface.

Boundary Conditions for Direct Computation of Aerodynamic Sound Generation [PDF]

open access: yes, 1993
Accurate computation of the far-field sound along with the near-field source terms associated with a free shear flow requires that the Navier-Stokes equations be solved using accurate numerical differentiation and time-marching schemes, with ...
