Electric Pumps for Space Propulsion

by Kerry Oliphant on Apr 5, 2018 12:57:56 PM

The recent success of Rocket Lab, putting small satellites into orbit with its Electron rocket, is a significant milestone in the evolution of space flight.  The Electron rocket is powered by a set of 5,000 lbf thrust Rutherford engines that use battery-powered electric motor-driven pumps to supply the LOX and Kerosene to the thrust chamber.  Battery-powered propellant feed pumps are a leap in technology that will reduce the development time and lower the costs of space flight.

Design Elements that Affect Machining Time in Turbomachinery

The primary options for laying out an impeller (i.e. flank milled versus point milled, open versus covered impellers, integral versus welded shrouds) determine the basic manufacturing process (see Manufacturing Methods Used for Turbomachinery for more info).  Beyond the basic layout, there are several other details of the design that can significantly affect manufacturability. They include: 

The Future of Turbomachinery Software

by Mark R. Anderson on Sep 9, 2016 11:27:00 AM

The turbomachinery and software industries have evolved, in tandem, to high levels of maturity. On the engineering side, improved modeling capability and access to more powerful computational resources have revolutionized the design process, reducing costs and significantly improving performance and reliability. On the manufacturing side, additive manufacturing is starting to open up exciting new possibilities by allowing component shapes that simply were not possible before. 

Like all technology, the evolution of these methods may seem clear enough for the near future, but it can be much more hazy over the long-term. Therefore, this article will take a look at what the future of  turbomachinery software may hold.
