NASA and Virgin Orbit 3D Print, Test Rocket Combustion Chamber
Rockets are full of specially made, one of a kind, components. 3D printing could help lead to less expensive rockets that are quicker to build and easier to iterate on.
Virgin Orbit air launches rockets carrying small satellites to space. The company partnered with NASA experts in combustion and additive manufacturing, or 3D printing, at NASA’s Marshall Space Flight Center in Huntsville, Alabama; Glenn Research Center in Cleveland; and Armstrong Flight Research Center in Edwards, California. Their goal: to create a 3D printed combustion chamber that combines multiple materials and takes advantage of cutting-edge manufacturing processes.
The effort incorporates a proven NASA additive copper alloy, GRCop-84, which was developed at Marshall and Glenn in 2014 to successfully print and test the first full-scale 3D printed copper rocket engine part. To further strengthen this new engine thrust chamber, Virgin Orbit used its own hybrid additive/subtractive machine to apply a second bimetallic super-alloy jacket and precisely machine the part.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
