Scientists Built An Impossibly Small Engine But Don't Know How It Works

It must be fun to invent something. One day it does not exist, and the next day it exists. But how would you feel if you didn’t exactly know why your new invention worked? The minds behind this all-new microscopic engine could tell you.


If You're A NASA Engineer You Get To Play With Toys Like These

If you’re a NASA engineer, you get to play with a lot of awesome toys, like these furious mini-rockets. They are models of the Space Launch System (SLS) core stage engines, “scaled down to just 2 per cent of the actual size of the flight hardware”.


Why Engines Are Commonly Measured In Horsepower

We owe this unit of engine power measurement to Scottish engineer James Watt. In the early 1780s, after making a vastly superior steam engine to the then classic Newcomen steam engine, Watt was looking for a way to market his invention, advertising the fact that his engine used about 75 per cent less fuel than a similarly powered Newcomen, among many other improvements.


Monster Machines: You Can Cradle This 3-Cylinder Engine Like A 40kg, 400hp Baby

An engine this small should, by conventional logic, not be this powerful. But, somehow, it is. And at this year’s 24 Hours of Le Mans, Nissan plans to see just how well its undersized, overpowered hybrid engine prototype handles auto racing’s most gruelling challenge.


GM's RFID Engine Bolts Prevent Assembly Line Screw-Ups

Threaded fasteners haven’t changed drastically since they were invented ages ago. But now, General Motors has put RFID tags in the bolts used on engine assembly lines, turning simple hardware into tracking devices that make sure everything gets assembled properly. That bolt’s got a (2kb) brain!


Monster Machines: It's Not Broken, The Open Rotor Turbine Is Supposed To Look Like That

This is not a broken turboprop engine. It’s a new radical new aircraft engine design by French engine manufacturer Snecma, one that will forgo the traditional bypass system and remove the engine ducting altogether while reducing fuel consumption, greenhouse gas emissions, and engine noise.


This Wonderful Sound Is A Turbine Engine's Worst Nightmare

Turbines are huge, intricate, beautiful machines. And if you drop something inside of them, they double as musical instruments. But as YouTuber AgentJayZ demonstrates, the delightful xylophone sound that makes is actually horrible.


Jet Engines Endure Trial By Ice

Today’s shot of the day is from GE’s engine testing site in Winnipeg, Canada, where new engines endure trial by ice — a simulated winter gale that batters them with 1270kg of cold air per second and thousands of gallons of freezing water, all at minus eight degrees fahrenheit. [GE; Gizmodo]


Monster Machines: The Next F-35 Lightning's Engine Adapts For Flight, Fight And Beyond

Unlike commercial airliners, modern military aircraft are subjected to ever-changing flying conditions — from high-thrust takeoffs to flying at altitude to combat manoeuvres. So why are they outfitted with engines that perform optimally in only one of those flight envelopes? For the next iteration of the F-35 Lightning II, Pratt and Whitney is developing an engine that performs at its best no matter what’s required of it.


2014's F1 Cars Are Going to Sound Rubbish

The FIA’s decided to get with the program of fuel efficiency and is forcing every F1 team to swap their beastly and incredibly-high-revving 2.4L V8s for smaller 1.6L V6s with turbos. On the face of it, that’s better for our normal-car tech development, but what it means is they’re going to end up sounding a bit crap. Like vacuum-cleaner whiny. Rubbish.
