AFRL Researches Use of Pulsed Coolant for Film Cooling

Coolant flow reduction is an important design goal in the development of advanced turbine engines. Turbine engine designers routinely use film cooling to cool engine components in the hot-gas flowpaths. Film cooling is the process of injecting coolant fluid at one or more discrete locations along surfaces regularly exposed to a harsh,

AFRL Successfully Demonstrates Lightweight Modular Support Jammer

AFRL engineers successfully demonstrated several support jamming techniques at the Naval Air Weapons Center, California. The lightweight modular support jammer (LMSJ) is a scalable-architecture, digitally controlled support jammer based upon digital common modules and highly integrated transmitters and apertures. The total end-to-end system will

AFRL Develops Network-Centric Monitor for Multiple Heterogeneous Datastreams

Engineers from AFRL and ITCN, Inc. (Dayton, Ohio), are developing a real-time data monitoring and correlation (RTDMC) system to acquire data from multiple heterogeneous data streams simultaneously, and time-correlate events contained in the data content. This data acquisition is controllable and distributable over local or global networks. The team

SBIR Company Advances Future Space Computers

Onboard computers are the primary means of operating satellites that cost millions of dollars to build and launch; once in orbit, however, these computers are not easily repaired if problems arise. Furthermore, space-deployed hardware cannot tolerate data errors, since ordinary microchip performance degrades considerably outside the earth's
