A new thermal protection concept is described and an investigation to determine its feasibility and quantify its performance is proposed. The concept involves placing an array of small cavities in the nose region of a typical hypersonic interceptor (projectile, missile, or submunition). The cavities act as multiple Helmholtz resonators, and can be made to operate in a very predictable manner to ...

AN ANALYTIC MODEL OF A WIDE FIELD, PHASED ARRAY IMAGING SYSTEM WILL BE DEVELOPED. THE MODEL IS BASED ON A MEASUREMENT SYSTEM CAPABLE OF ERROR MEASUREMENT DIRECTLY WITH RESPECT TO THE FINAL IMAGE PLANE. THE BEAMS FROM INDIVIDUAL SUBAPERTURES WILL BE COMPACTED AND CONFORMALLY MAPPED TO A DEMAGNIFIED PUPIL. WE WILL DEVELOP NONREDUNDANT, CODED APERTURE MASKS TO BE INSERTED AT THIS COMPACT PUPIL WHICH ...

Controlling millimeter radio frequency waves with optical signals is a requirement for military communications and radar systems. The advances in the past decade have led to photonic sensors and switches that utilize light beams interacting with RF devices. New capabilities extending to higher frequencies and working over multiple frequency bands are possible using a combination of nonlinear op ...

This project will develop a method for forming and emplacing a horizontal barrier within a groundwater aquifer to prevent downward migration and further contamination of groundwaters by Non-Aqueous Phase Liquids (NAPLs). Certain properties of the immiscible liquid system act to form the barrier from injected particulate or colloidal materials and to stabilize the barrier once it is form ...

This effort builds on initial feasiblity analysis and measurements taken to support concealed weapon detection. DSA proposes a nine month program consisting of two (2) items. Item 1 (6 months - 5 tasks) conducts CWD analysis, measurements, evaluation, system design and ends with the delivery of a draft Final Technical Report (Task 5). Item 2 (3 months - 1 task #6) refines and elabor ...

The Reconfigurable Operator Station Simulator (ROSS) project will provide designers of operator stations for Uninhabited Aerial Vehicles (UAVs) with a rapid prototyping system. In addition, the architecture on which ROSS is based provides a platform on which to build tools that increase the ability of operators to control UAVs and to impart a far greater understanding of the situation to them. T ...

The Air Force has identified the need to develop affordable flight control technology to support Air Force Global Engagement objectives. Of particular interest to the Air Force is the development of real-time optimization algorithms for cooperative engagement solutions among Uninhabited Air Vehicles (UAV) in a multiple target environment. DSR proposes developing a real-time, rule based, Cooperat ...
