MBSE-Driven Systems Engineering Visualization Suite

NASA’s Jet Propulsion Laboratory, Pasadena, California There is a need to define the information architecture, ontologies, and patterns that drive the construction and architecture of Model-Based Systems Engineering (MBSE) models, but less clarity is given to the logical follow-on of that effort: how to practically leverage the resulting semantic richness of a wellformed populated model.

4 Steps In Selecting Fluid Connectors For Medical Device And Equipment Applications

With so many risks and options for connecting tubing in medical applications, it is important to have a simple and repeatable strategy for selecting the best connector solution. The process requires a thorough analysis of the application in order to ensure connectors will be compatible with the physical, chemical and biological environment, and be easy to use and help prevent misconnections—whether the application involves connecting air lines for a blood pressure cuff, connecting reagent supplies to a blood analyzer or making critical connections between a patient and heart-lung machine.

The Future of Exploration Starts With 3D Printing

Last year, engineers at NASA’s Marshall Space Flight Center in Huntsville, AL, tested an additive manufacturing process that is being used to make some of the parts for NASA’s new rocket, the Space Launch System (SLS), more efficiently and affordably without compromising performance and safety. Selective laser melting (SLM) is a 3D printing process used to create complex parts for the engine and other components of the rocket. Four RS-25 engines and two solid rocket boosters will power the core stage of the SLS.

Solar Orbiter Instrument Filters Powered by Brushed Motor

maxon RE 13 brushed DC motors maxon precision motors Fall River, MA 508-677-0520 www.maxonmotorusa.com In 2018, the European Space Agency (ESA) will send the Solar Orbiter into space. A joint project of the ESA and NASA, the Solar Orbiter will be an important milestone in the exploration of the Sun. An American rocket will take the probe into space, and it will travel for three years until it can begin its work.

Editor’s Choice: May 2016

A non-explosive rock splitter uses high-temperature shape memory alloys (SMAs) as the driving member. The SMAs, in the form of cylindrical pellets, generate extremely large forces to fracture rock-like materials and minerals when used with DC voltage heaters placed in boreholes. The devices can be used for breaking rocks where the fracture of large samples is required, or where explosive or impact techniques can’t be used because of the damage they could cause to the underlying sample. Find out more HERE.

NASA’s New Rocket Will Feel the Force

At NASA’s Marshall Space Flight Center in Alabama, construction is underway in Building 4619, a multipurpose, high-bay test facility that has been a hotbed for all types of testing, including loads, acoustics, vibration, extreme temperatures, high and low pressures, and environments that simulate the cold, black conditions of outer space.
