Analytical tools, such as structural dynamics analysis software, structural and thermal load analysis software, and load coupling analysis software, and flow analysis software are the same for launch vehicles of any type. Improvements in software quality and capability and the understanding of how to use the software inevitably improve with greater involvement. Measures taken to increase the performance and reliability of specific launch vehicles translate directly into performance and reliability improvements for all launch vehicles. One of the most critical technologies that can be improved is the engineering skill and experience required for interpreting and rectifying design problems that occur during system development. A difficult area to gain engineering expertise and knowledge is solid rocket motor case bond and grain design.
Experience is one of the best teachers.
Every launch vehicle flight that features a solid rocket motor propulsion component adds to the body of experience and knowledge. In summary, the U.S. space launch and strategic industrial bases are one and the same. A loss of satellite launch business to foreign competition diminishes companies that support the U.S. strategic deterrent, while at the same time subsidizing the development of a foreign capability. We experience a loss of our strategic capability and business while theirs grows. The U.S. Government and American taxpayer enjoy benefits from U.S. commercial satellites placed into orbit on launch vehicles with components and subsystems made by U.S. companies.
