Electromagnetic, Thermal, Stress and Deformation Analysis of a Space-Based Satellite Dish Antenna
This paper presents a multiphysics analysis of a space-based communication satellite antenna. Electromagnetic losses due to induced high-frequency surface currents lead to partial, asymmetric heating of the structure, causing stress and deformation. A final electromagnetic analysis is performed on the resulting deformed structure to determine the effect of the deformation on … [Read more...]

The … [Read more...]
Military Electronics Thermal Management Challenges Spark Innovation
Several trends are influencing thermal management in military and aerospace environments, including smaller electronic packages, components that fit into tighter spaces, and more powerful chips and IC packages. Packing more powerful components into smaller air-tight spaces creates major heat dissipation problems, an example of how size, weight, and power (SWaP) constraints … [Read more...]
Final 787 Test Aircraft Completes Maiden Flight
Despite being cut short by a liquid cooling leak, Boeing’s sixth and final 787 Dreamliner has successfully completed its long-delayed maiden deployment, program sources said. The aircraft, which is the second of two General Electric GEnx-1B-powered 787s, departed Boeing’s Paine Field in Everett, Wash., on Oct. 4 and lasted just over an hour with an aircraft recovery at Boeing … [Read more...]
