The Gyroscopic Effect
by Thomas Gresham, Senior Mechanical Design Engineer
This post covers one of the fundamental issues that makes rotordynamics a unique subject: The Gyroscopic Effect. The gyroscopic effect can be observed in the behavior of spinning tops, fidget spinners, inertial navigation systems, and many types of turbomachinery. If you have ever tried to tilt an object while it is spinning, then you may have noticed this effect.

Part 2: Hydrogen Turbomachinery Design
by Mark R. Anderson, Chief Technical Officer, Concepts NREC
Hydrogen is attracting a lot of interest in different circles these days from: propulsion, to energy storage, to personal transportation. The most obvious benefit of hydrogen fuel is a total lack of carbon in the exhaust products. This is rare for a fuel that’s a fairly high energy substance to begin with. More specifically, its high energy in terms of energy per unit of weight but somewhat less so in terms of volume.

Part 1: Hydrogen and Turbomachinery
by Dr. David Schowalter, Sr. Director, Global Software Sales
Because of its promise as a non-polluting fuel, hydrogen is currently a very popular topic among the energy and turbomachinery communities. If hydrogen is reacted with pure oxygen, the thermal energy release is significant, and water is the only by-product. This highly exothermic reaction was used to get humanity to the moon. Of course, nitrous oxides (NOx) can be released if hydrogen is burned in air. If, on the other hand, the energy from the reaction is converted to heat and electricity in a fuel cell, then only water vapor is discharged. In addition, when pressurized in a tank, hydrogen is an easily transportable fuel, and so is desirable for transportation.
