Last week the Department of Justice announced the conviction of Wenxia Man by a federal jury. The crime? Conspiring to export military jet engines and drones to China. Not plans. Not components. Entire jet engines and drones.
To keep the Raptor’s radar signature at a minimum, small doors and vents appear seemingly out of nowhere during certain functions, reminding us that a fighter jet still lies beneath its spaceship-like appearance. Its startup sequence also looks and sounds like something out of science fiction.
Given the challenges with precision, building functional machines with a household 3D printer isn’t easy. And that’s why it’s all the more impressive that someone on the RC Groups forum has used a 3D printer to make a fully-functional scale model of a Boeing 787’s GE-built turbofan jet engine.
Curious about just how far they could take the company’s additive manufacturing technology, engineers at GE Aviation’s Additive Development Center in Cincinnati successfully created a simple jet engine, made entirely from 3D printed parts, that was able to rev up to 33,000 RPM.
This week, engineers working on the Bloodhound Supersonic Car installed its EJ200 jet engine into the chassis for the first time. Good news: it fits. Bad news: they now have to install kilometers of cabling into the small gaps that are left. [Bloodhound Project]
Here's the good news: General Electric has created a wonderful 3D model of a jet engine that anyone—even those lacking an aerospace engineering degree—can build themselves, complete with moving parts and a cutaway design so you can see everything in motion.
If you're wondering how this snowboarder is moving so fast on flat ground, the answer is simple. He's holding powerful jet thrusters in his hands. Yes, jet thrusters. This is awesome.
It's not the setup for a joke. Jets and light bulbs really do have something in common now that GE is using jet engine cooling mechanisms inside bright, lightweight, low-energy LED bulbs. You'll have to wait to buy them though.
Ahh, so this is what happens when you strap a 7000 horse-power General Electric J85 Jet Engine (with a 200mph top speed) to a Ford F650 pick up truck. Slightly underwhelming video after the jump.
Batman normally likes to stretch his legs and have trunkspace for a few accidental dead bodies. But he might pilot an ATV powered by a jet engine on a weekend at the links.
Keeping computers cool is becoming more of a challenge, forcing some hobbyists to fill their PCs with various liquids, and causing Google to build two four-story cooling towers for its new monster computer project in Oregon. HP engineers have a better idea. They've turned to tiny radio-controlled model jet airplane…
