ABSTRACT:Recent technical demonstrations in hostile fire sensing and classification have highlighted the use of costly cryogenically-cooled electro-optical sensors.While capable, these types of sensors come with a higher initial purchase price as well as high life cycle costs per platform.This activity will implement a broad area hostile fire sensing architecture that uses lower cost discrete sens ...

ABSTRACT:The objective of this proposal is to design an inexpensive hypersonic test article with an associated instrumentation package capable of providing measurements necessary for advancing the understanding of aerothermal behavior in the hypersonic flow regime. Significant advances and accuracy validation within multi-physics computational science and engineering (CSE) toolsets (such as comput ...

ABSTRACT: Many turbomachinery applications have achieved improved availability, reliability and cost savings by incorporating health monitoring systems to determine the mechanical condition of key components in near real time. The goals of any health monitoring system are to ensure reliability by avoiding unplanned maintenance, to reduce operating costs by providing the information needed to plan ...

ABSTRACT: The Air Force spends $4.5 billion annually on aircraft maintenance related to corrosion.The source of this corrosion frequently is airborne chlorides that settle on metal parts and sensitive avionics and then absorb moisture from the air to create an electrolyte that promotes galvanic corrosion.The proposed work will design, fabricate and test a Corrosion Mitigation System (CMS) that sup ...

ABSTRACT: The objective of the effort is the development of a Femtosecond Laser Electronic Excitation Tagging (FLEET) system and data analysis tools for the measurement of transport parameters in nitrogen and air ground test facilities without seeding the flow with either particles or with foreign gases.  The effort follows Phase I accomplishments, wherein a transportable FLEET laser system with ...

ABSTRACT:The warfighter needs an accurate and reliable source of Position, Navigation, and Timing (PNT) when GPS is not available. Fortunately, technical advances in navigation sensors and algorithms can reduce dependence on the venerable, yet vulnerable, GPS system. Inertial sensors are becoming increasingly smaller and more accurate. Low cost, powerful embedded computing platforms enable real ti ...

ABSTRACT: Global Engineering and Materials, Inc. (GEM) along with Columbia University propose to develop a simulation tool for modeling mixing process of multi-particle composite systems and generating the ultimate microstructure. A combined theoretical, numerical, and experimental approach will be developed to create a high fidelity software product with a reduced order modeling capability for an ...

Boundary-layer transition is important in the design of hypersonic vehicles since it significantly affects the aerodynamic drag and heating.The ultimate goal of this SBIR project is to assemble an easy-to-use, accurate, efficient and robust suite of codes to predict boundary-layer transition on hypersonic vehicles in large-scale wind tunnels and flight.The Phase I objectives are to develop algorit ...

The proposed effort aims to develop and demonstrate an innovative software tool combining surrogate modeling and image compression techniques for high-speed hyperspectral image extraction from plume signature databases. Salient aspects of the proposed solution are: (1) image compression and data-driven surrogate modeling operate in concert to capture the effects of various parameters (Mach number, ...

ABSTRACT: The extreme ejection conditions in the fifth-generation fighter F-35 could lead to occupant injury. Rocket sled testing of ejection seat with manikins is limited in simulating human response. The current neck injury models and injury criteria from automotive safety are inadequate for the ejection-related injury. We propose to develop the global-to-local finite element models (FEM) and si ...
