Toward Virtual System Prototyping: Challenges and Enablers in Modeling Systems

In conjunction with SAE As companies strive to advance their modeling and simulation capabilities toward realizing full virtual prototypes of aircraft systems, they face a number of challenges associated with assembling multi-domain system models. Beyond the inherent time and budget pressures, they interact and collaborate with a variety of departments, suppliers, and manufacturers as a source of models. They must deal with a diverse mixture of tools, modeling formats, and conventions of different domains, and they must preserve and repurpose an often decades-old legacy of modeling knowledge and assets. This 60-minute webinar will discuss these challenges and describe technologies and approaches that can help engineering organizations achieve their virtual system prototyping visions, including modeling languages, reduced-order modeling, and interoperability standards.

New Methods Detect and Predict Fatigue-Related Aircraft Cracks

Researchers are developing tools and technology to detect the formation of cracks in aircraft components and monitor their progression. The team is conducting comprehensive testing and characterization studies to understand and monitor how tiny cracks are initiated and grow in metal components as they are subjected to repetitive strains and stresses similar to those that wings, fuselages, and other aircraft components experience in service.

Precision NASA Thruster Keeps Spacecraft Still

The European Space Agency’s LISA Pathfinder spacecraft is on its way to space with the Disturbance Reduction System (DRS), a thruster technology developed at NASA's Jet Propulsion Laboratory. The DRS uses colloid micronewton thrusters, the first of their kind, to keep the spacecraft as still as possible and compensate for solar pressure. These thrusters electrically charge small liquid droplets and accelerate them through an electric field in order to generate thrust.

Nano-Submarine Motors Powered by Light

Each of the single-molecule, 244-atom submersibles built at Rice University has a motor powered by ultraviolet light. With each full revolution, the motor’s tail-like propeller moves the sub forward 18 nanometers. And with the motors running at more than a million RPM, that translates into speed. Though the sub’s top speed amounts to less than 1 inch per second, that’s a breakneck pace on the molecular scale.

Wearable Equipment Supports Human Motion

The Unplugged Powered Suit (UPS), a new model of pneumatic muscle and an active type of assistive equipment incorporating the muscle, is wearable equipment that supports human movement without requiring any electronic devices and tanks. It employs a newly developed pneumatic muscle named Pneumatic Gel Muscle (PGM) as an actuator.
