Trajectory Simulation for Single Balloons and Networks
An understanding of the characteristics of trajectories of constant-altitude stratospheric platforms is important for scientific balloon flights because science observation sequences, safety planning, overflight negotiations, launch site selection, and recovery operations are affected by trajectory. Supported by NASA, Global Aerospace Corporation (GAC) has developed a Trajectory Simulation and ...
متن کاملNasa & the next Generation Air Transportation System (nextgen)
Although today’s National Airspace System (NAS) is one of the safest means of transportation, it has evolved into a large, complex, distributed, and loosely integrated network of systems, procedures, and infrastructure without the benefit of seamless information exchange. The process of control is primarily through the use of surveillance radars, voice radio systems, limited computer support sy...
متن کاملThe NAS Parallel Benchmarks 2.0
We describe a set of implementations of the NAS Parallel Benchmarks based on Fortran 77 and the MPI message passing standard. These implementations, which are intended to be run with little or no tuning, approximate the performance a typical user can expect for a portable parallel program on a distributed memory computer. They complement rather than replace the original NAS Parallel Benchmarks....
متن کاملAgglomeration Multigrid for the Three-dimensional Euler Equations
A multigrid procedure that makes use of coarse grids generated by the agglomeration of control volumes is advocated as a practical approach for solving the threedimensional Euler equations on unstructured grids about complex con gurations. It is shown that the agglomeration procedure can be tailored to achieve certain coarse grid properties such as the sizes of the coarse grids and aspect ratio...
