The primary objective of this Phase I proposal is to design, develop, and demonstrate the feasibility of a power factor compensation device for a 65 kVA, 115V, 400-Hz aircraft power system. Based on identified power factor conditions in the F-18 Super Hornet platform, the compensation system must correct an existing leading 0.98 power factor to a target lagging 0.93 (minimum objective lagging 0.97 ...

Modern military and commercial gas turbine engines are subject to increased durability, performance, and safety issues when operating in austere environments where significant quantities of sand, volcanic ash and dust are present and can be ingested into the engines. These environments include desert regions, as well as, previously active/currently active volcanic areas. Military studies of turbin ...

Standard protocols such as SSL, SSH, etc. are implemented as one-size-fits-all libraries. To maximize compatibility, these libraries implement rarely used features that increase attack surface. Examples include the SSL Heart Beat feature (HeartBleed) and weak SSH ciphers (LOGJAM).The Navy would like to reduce software attack surface by removing unused protocol features. Our proposal, LeastProtocol ...

Under this Phase II effort, the design of a modular 60 kw (3.6 MJ) shock tolerant composite flywheel for backup/ride through power will be finalized. This composite flywheel design will make use of a novel low cost thermal press cure process to fabricate the individual composite rings used to build up the flywheel. The manufacturing process parameters used in previous hydroburst testing of initial ...

The objective in this project is to implement and validate a probabilistic qualification framework that will enable additive manufacturing (AM) materials and part qualification through the use of a data-driven predictive model within a statistical framework. Senvol seeks to develop and validate a data-driven ICME probabilistic framework for assisting qualification of AM materials and parts. Phase ...

The Candent Technologies “Reduced Cavitation, High Efficiency Outboard Propulsor for Small Planing Craft” Phase II program is structured to develop an advanced waterjet propulsor for the Combat Rubber Raiding Craft (CRRC). This new axial flow waterjet propulsion system is designed as a “bolt on” assembly that replaces the lower unit of the existing MFE 55 outboard motor. This new propulsio ...

Affordability, safety and reliability are major objectives of Navy Strategic System Program for continued life extension of the D5 Trident Missile. Currently, silver zinc reserve batteries are being employed in those missile systems. Silver zinc batteries have the advantage of high energy density, high power density and excellent safety. However, silver zinc batteries have the drawbacks of short s ...

Software bugs are a significant risk to mission success and human safety. Software testing and analysis, which is used to combat bugs, is difficult, and thus time-consuming and expensive. It is particularly difficult to find latent bugsbugs that do not have obvious, observable effects on the system. This results in undiscovered and unfixed bugs in the system. New approaches to automated software t ...

Implement extended life improvements based on an accelerated life development tests to confirm delamination failures and associated activation energy levels of adhesives. Testing results will be used to create models and design tools to aid in development of improved life expectancy of Transparent Armor systems. Designs will be used to develop Transparent Armor samples for developmental and qualif ...

This proposal offers SPIHT compression for near-lossless and strictly lossless compression of acoustic array data. We show in tests on publicly available acoustic data that the requirements of 5:1 compression ratio and almost zero distortion are satisfied by 1D-SPIHT coding of the single stream output of the acoustic array. Because 1D-SPIHT has low complexity in addition to high efficiency, the co ...
