All the Sexy Aerospace Stuff That is Happening

It was sometime around 1988 and it was pitch dark outside. I and some of my aerospace colleagues from work were driving in a car caravan from San Diego to Edwards Air Force Base at the ungodly hour of 3AM. The Space Shuttle Discovery was scheduled to land that morning and we wanted to see it.

From the moment I woke up in the middle of the night and all the way through the drive to Edwards AFB to the parking and walk to the viewing area to the standing in the cool, early morning air for a couple hours, I was questioning whether the whole effort was worth it. The landing of Discovery was not even certain. Weather conditions could postpone the whole thing.

And then someone pointed at the sky and yelled "There she is!". And I saw her too. Then a minute later we all heard the distinct double sonic boom. And I instantly knew it had been worth it.

Are Oil Companies Really That Backwards?

I had to laugh when I read this article in last week's edition of Businessweek "Big Oil’s Rejection of Silicon Valley Is Finally Coming to End". Who would have thought oil companies were so backwards? I bet they still use sliderules too! Here is one of the opening quotes:

“Onshore North America used to be a market where state-of-the-art technology went to be humiliated,” said Tom Curran, an energy analyst at FBR Capital Markets & Co. “You’ve had a clear shift occur where onshore North America for the first time in recent history has become a technology play.”

As I have alluded to in other blogs, I myself came out of the aerospace industry. I have always been involved in technology. Heck, I am an engineer. Apparently the only technology that counts as real technology happens in Silicon Valley.

NPSH got you under pressure? This’ll get you pumped!

Cavitation is an important subject in piping systems. Quite often, cavitation is an operating condition that is to be avoided, such is the case with pumps. Not only can cavitation cause serious decreases in pump performance, but it is also a maintenance nightmare if left unaddressed. Such issues are costly and may lead a system to be deemed unsafe. As you are likely aware, cavitation exists when the local pressure falls below the vapor pressure of operating fluid. Overtime the pressure may increase again so that the cavity formed then collapses. When this collapse occurs on the vanes of a centrifugal...

Blast off with a revolutionary feature, Rotational Acceleration!

The success of rotating hydraulic systems could revolve around the methods employed, make sure to use only the best when modeling such a system. As the surge of space travel innovation continues, safety always comes to mind.  All too often the hazards of traveling through the colloquial final frontier prove the necessity of double checking calculations and the validity of the adage, units kill.  With the large number of piping networks that can rotate around an axis in the absence of the earth’s typical gravitational pull rotating objects involved in space flight, these systems are no exception to the hard-learned lessons...

Swing Check Valves: As Easy as Pie

What is a Pi-day without a Tips and Tricks blog? That's the $64,000 question today as you are undoubtedly preparing yourself three slices and a sliver of the delicious delicacy. Well the answer is, it's just not as great of a celebration as it could be; so today we are bringing you the scoop on modeling swing check vavles in AFT Impulse ! Last month I published a blog about hydraulic ram pumps and how they work along with tips to model them in Impulse. If you haven’t read that yet, go check it out here. In the blog, I mention...

2000 Years of Roman Pipe Technology and 100 Years of American Pump Technology

This past week I and Jeff Olsen, AFT’s V.P. of Technology, attended the annual conference of the Hydraulic Institute . The Hydraulic Institute (HI) was founded in 1917 and is America’s premiere pump organization. At this year’s meeting HI held a centennial celebration . For a technology organization like HI, 100 years is quite a feat and was rightly celebrated at the annual meeting this year. Many of you are familiar with HI through the standards HI creates. These standards show up in AFT Fathom in several places: Intake design  (pump submergence to avoid vortex formation) Pump viscosity corrections Slurry pumps...
