A tetrahedral mesh generation method for acquiring accurate sonic boom pressure signatures several body lengths from an aircraft model has been developed. The method serves as a tool for aerodynamicists to efficiently create useful meshes for sonic b

A number of variations may include a front center airbag system comprising: a first airbag mounted on an inboard side of a first front seat and a second airbag mounted on an inboard side of a second front seat, wherein the first airbag and the second

Many models of supersymmetry breaking involve particles with weak scale mass and Planck mass suppressed couplings. Coherent production of such particles in the early universe destroys the successful predictions of nucleosynthesis. We show that this p

The technibaryon constitutes a possible dark matter candidate. Such a particle with electroweak quantum numbers is already nearly ruled out as the dominant component of the galactic dark matter by nuclear recoil experiments. Here, the scattering of s

The ability of inviscid computational fluid dynamics (CFD) codes to compute sonic boom pressure signatures is examined using three different codes that solve the Euler equations of fluid flow on structured hexahedral and unstructured tetrahedral grid

A dual depth passenger air bag technology has been developed which provides two different deployed cushion shapes coupled with two inflation levels, but only uses two initiators, one for a single level inflator and one for a dual depth mechanism. The

Two unstructured-grid Euler-based CFD codes, AIRPLANE and FLOWCART were coupled to a gradientbased quasi-Newton finite-difference optimization algorithm. These two optimization techniques were developed to provide detailed aerodynamic shape optimizat
