Computer-Aided Design (CAD)

Magnetic materials can attract or repel each other based on their polar orientation — positive and negative ends attract each other, while two positives or two negatives repel. When an electromagnetic signal like a radio wave passes through such materials,...

Designing any product — from complex car parts to wrenches — is a balancing act with conflicting performance tradeoffs. Making something lightweight, for instance, may compromise its durability.

The Small-Body Dynamics Toolkit (SBDT) v5.0 is a collection of primitive-body-specific trajectory design and analysis tools written in MATLAB®. The SBDT gives the user the capabilities to propagate, analyze, and visualize spacecraft trajectories and the dynamical environment near realistic asteroid, comet,...

NASA Marshall has developed a system for generating iodine vapor from solid iodine for use as a propellant in a Hall or ion thruster propulsion system. Xenon has generally been the preferred propellant for these spacecraft ion propulsion systems but more recently, iodine-based...

With self-driving vehicles poised to take the road, how can today’s engineers prepare themselves to support an autonomous future?

A connectors expert reviews standards and certifications; assembly tooling; and physical space issues.

Just because it's computer simulation doesn't mean it's virtual prototyping. Our expert explains.

Simulation tools offer insight into the physical processes of heavy-duty engines. But what about natural wear and tear?
