The goal of this program is to design and fabricate selected liquid rocket engine combustion components. This goal will be accomplished by developing a low-cost, near net-shape technology for fabrication and rapid densification of ablation and oxidation-resistant LRE components for a wide variety of Air Force missions. The material which will be used for this purpose is zirconium diboride/boron ...

Future battlefields will require independent operations and increased operational tempo, placing severe burdens on weapons platform crewmembers in the areas of information flow management, data fusion, and assessment of data to arrive at the most tactically acceptable decisions. Work continues in the development of decision aids to assist direct/indirect fire weapon platform commanders in accompl ...

THIS PROPOSAL DESCRIBES AN APA OPTICS PROGRAM TO DEVELOP A HIGH SPEED (100GHZ) GAAS WAVEGUIDE BASED MACH ZEHNDER MODULATOR. OUR APPROACH CENTERS ON THE USE OF A BURIED ELECTRODE CONFIGURATION TO ACHIEVE VELOCITY MATCHING OF THE RF AND OPTICAL SIGNALS. THIS WE FEEL WILL RESULT IN A DEVICE WITH A BROADBAND RESPONSE FROM DC TO 100GHZ. WE WILL WORK IN CONJUNCTION WITH THE ULTRFAST SCIENCE LAB AT THE U ...

Immunization has proven to be an effective method of protecting both military and cibilian populations from disease caused by bacterial, viral, or toxic agents. The U.S. military faces the problem of protecting its personnel from incapacitation caused by exposure to agents of both natural and man-made orgin. In developing countries, immunization is the most cost-effective weapon for disease prev ...

An advanced ceramic heat recuperator (ACHR) incorporates thin corrugated,d triangular-shaped flow channels made of non-oxide ceramics with high thermal conductivity and high fracture toughness. A counterflow arrangement together with the unique design of the flow channels makes the ACHR highly efficient, highly reliable and compact. A key processing innovation is also made for fabrication of the ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

Development is proposed of a new, rotary form of Stirling cryocooler which offers longer operating life and much lower vibration than reciprocating forms of cryocoolers. The proposed machine has fewer moving parts to wear and can be completely balanced to eliminate vibration in all planes by simple counterweights on the shaft, which is not possible in reciprocating machines. The rotary desi ...
