Using HyperWorks to Generate Electrically Large Surface Meshes for Radar Cross Section or Antenna Placement Simulation

Radar Cross Section (RCS) and installed antenna placement are important parameters for aircraft designs. RCS is a measure of how detectable an object, such as an aircraft, is with radar. A large RCS indicates that an object, such as a jet aircraft, is easily detected.<br><br> SELEX Galileo used HyperWorks to generate arbitrarily large surface meshes, with defined electrical properties at the element level, for use with electromagnetic (EM) solvers to calculate either RCS of an aircraft or to determine where to place an antenna for optimum performance.<br><br> For this case study a fast-jet aircraft with approximately 100 million mesh elements was assessed for radar tracking and avoidance capabilities.

The Most Common Mistakes Engineers Make In Thermal Modeling

Engineers and designers are increasingly relying on modeling solutions to prototype, test, prove and experiment as a means to more accurately predict how a built vehicle or other application will respond to various thermal conditions.

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments

The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.
