With the continued electrification of military systems, lithium-ion (Li ion) batteries are increasingly targeted for electrical energy storage due to exceptional energy and power density. However, Li ion batteries operating in hostile thermal and mechanical environments typical of military aircraft are prone to catastrophic thermally-induced failures. Hazards including loss of power, fire, and exp ...

Typical piping joint designs in the fuel systems of Navy ships are susceptible to weakening due to poor inherent weld quality and localized corrosion.The current composite patches and other processes that represent the state-of-the-art for reinforcemen...

The U.S. Navy seeks a proactive approach to reinforce the thin walled corrosion resistant steel (CRES) pipes at the welded joints in order to prevent potential leaks from occurring in situations where joint cracks are generated. Currently, there is no known product available to meet this need. Resodyn Corporation proposes for development a clear, tough, corrosion protective, VOC-free thermoplastic ...

Fault dynamics of large format lithium-ion (Li-ion) battery packs are complex, difficult to predict, and challenging to protect against. Consequently, there is great interest in developing fault mitigation strategies to optimize pack performance and prevent individual cell failures from propagating to other cells or the host platform. During this program we will evaluate active monitoring and cont ...

Current inspection methods for Integrally Bladed Rotors (IBRs) and compressor blades are limited to contact measurement systems that scan individual points, defined lines, or surfaces and non-contact systems that use point and line scanning techniques. ...

Expeditionary airfields (EAFs) are shore-based aviation support systems that are used by warfighters all over the world to rapidly launch and recover aircraft. EAFs are typically assembled on site using AM2 mats. Currently, AM2 mats are not reused beca...

Reliable ignition is critical to the operational performance of augmented military engines. Augmentors must reliably ignite when thrust is needed or system (and pilot) safety could be compromised. Augmentor ignition is particularly challenging relative...

The MK-48 torpedo requires a temporary crossover power supply until main engine activation and alternator power becomes available. Due to the high cost and poor availability of presently used thermal batteries, a suitable replacement power source using innovative energy storage concepts is desired. Creare proposes to develop an innovative high density power source based on a nanophosphate lithium- ...

H6 Systems proposes building a transmitter based on a modified coupled cavity TWT from CPI to increase coverage of MIL-STD-464C. Present testing methods are lacking in the coverage of power for frequencies from 3.0 3.3 GHz. The new transmitter will allow testing at both peak and average powers and will fill requirements for fields shipboard not in the main beam.

The single-crystal (SC) structure of modern jet engine turbine blades provides excellent resistance to high-temperature creep, allowing tight tolerances to be maintained over the life of the superalloy part. However, the turbine blade geometry includes complicated features that can promote the growth of discrete recrystallized grains that lower the parts creep resistance and may lead to catastroph ...
