Modern, high performance aircraft depend on the attainment of very flush fastener installations on their outer mold line (OML) surfaces to reduce parasitic drag and (in the case of stealthy "low observable" type aircraft) radar energy scattering. At the same time "cost of ownership" issues are driving the aerospace industry to produce more economical manufacturing and field supportable processes ...

This SBIR Phase I project aims to develop a capacitive energy storage system for UPS applications. The challenge is taken in consideration of the dielectric materials, the design of the capacitor array, and the discharge regulation in the circuit. The innovation emphasizes the development of capacitors with nanostructured dielectrics, in which the discharge process is governed by distributed rel ...

Graphite carbon electrodes have been used as the anode in recently commercialized rechargeable lithium batteries. However, the energy densities achieved to date for secondary lithium batteries have fallen far short of the theoretically attained mark. The specific energy or capacity of the Li-ion system, and for the anode process in particular, the Li intercalation efficiency, and the irreversibl ...

The firm proposes to conduct a program of research on real-time engine health monitoring (EHM) system for gas turbine engines. The proposed system is motivated by several factors: 1) effective monitoring improves engine performance and operability, 2) current engine monitoring field is fragmented and it needs standardization, 3) effective monioring requires advanced modeling and information pro ...

A novel, high energy density, aluminum-polymer propellant with ultra-high surface area and the potential for extremely high reaction rates, full utilization of the aluminum material, and an integrated fuel/oxidizer system is proposed. A patented ultra-high speed nanotechnology vacuum process is used to produce the nanolaminate material, which, even in powder form, can have hundreds of very thin a ...

In this study six techniques for effectively modeling and analyzing the trajectories of future space systems are investigated. These techniques are grouped into methods for modeling trajectories by conversion to a mathematical programming problem, and methods for solving mathematical programming problems. The first group includes parallel shooting, high-order collocation and differential inclusi ...
