The increasing number of missile launches and aircraft operation near missile test ranges has led to an increased hazard to the aircraft from wayward debris. The proposed study will systematically review and assemble the relevant data and applicable laws of physics into a computer program that will… More

Not Available Recently, optical fibers have gained a lot of popularity due to their performance advantages in commercial applications. Fiber optic technology is employed extensively for an ever increasing array of commercial and military signal transmission, communications and control… More

The Advatech Pacific, Inc. Team (API Team) will analyze historical programmatic data for selected space-system development programs that are representative of current programs of interest. These programs will be analyzed with respect to specific technologies that have gone through a technology… More

This STTR provides the Navy with a unique opportunity to fundamentally change the way ship design and analysis is accomplished by defining in Phase I the tools and computational infrastructure required to integrate selected individual specialty design and analysis tools into an overall Naval… More

There is a requirement for improving specific impulse and mass fraction in propulsion systems, while providing precision and predictability in thrust to enhance accuracy. These systems must be dependable and cost-effective at a high level of operational readiness. This contributes significantly to… More

Advatech Pacific proposes to develop a Virtual Satellite Integration Environment (VSIE) for the NASA Ames Mission Design Center. The VSIE introduces into NASA Mission Design Commercial Off-The-Shelf (COTS) Product Lifecycle Management (PLM) tools and processes, which haven proven themselves in the… More

Aeroelastic effects are significant design drivers in rotorcraft design. Typically, detailed structural information of the rotor blade necessary to determine its cross-sectional mass and stiffness properties is not available early on in the design process, especially for complex composite blades… More

An integrated environment for rapid design studies of small satellite missions will be developed. This environment will be designed to streamline processes at the NASA Ames Mission Design Center. Several key concepts are introduced. The proposed environment introduces modern Product Data Management… More

Sandwich structures often offer the most structurally efficient and lowest cost solution for airframe structures. However, for sandwich panels to interface with substructure and accommodate penetrations, the core must be ramped down to a solid laminate region. Designing and verifying the structural… More
