Variable-Nozzle Ducted Fan Provides Fluid Dynamics Lessons

Any student new to the principles of fluid dynamics will be familiar with Bernoulli’s principle and the Venturi effect, where the speed of a liquid or gas increases when the size of the condu…

Dyson Hair Dryer Becomes Jet Engine

While Dyson makes some good products, they aren’t known for being economical. Case in point: [Integza] spent $500 on a hair dryer. While he does have a fine head of hair, we suspected he wasn…

Ride-on Star Wars Land Speeder Gets A Real Jet Engine

When it comes to children’s ride-on toys, the Star Wars Land Speeder is one of the cooler examples out there. However, with weedy 12-volt motors, they certainly don’t move quickly. [Joe…

A Detonation Engine Prototyped Using Resin Printing

Over the years [Integza] has blown up or melted many types of jet engine, including the humble pulsejet. Earlier improvements revolved around pumping in more fuel, or forced air intakes, but now it…

High Speed RC Jet Car Is A Harsh Teacher

Making machines go fast has always been a seemingly unavoidable impulse for humans. With the advent of radio control, it’s possible to get a taste of the rush without putting your life and to…

This Jet Engine Will See You Through

Have you ever wished you could peer inside a complex machine while it was still running? We sort of can with simulations and the CAD tools we have today, but it isn’t the same as doing IRL. […

Adding Voluminous Joy To A DIY Turbojet With A DIY Afterburner

You don’t happen to own and operate your own turbojet engine, do you? If you do, have you ever had the urge to “kick the tires and light the fires”? Kicking tires simply requires …

3D Printing A Water-Cooled Jet Engine?

Everybody knows the trick to holding a candle flame to a balloon without it bursting — that of adding a little water before the air to absorb the heat from the relatively cool flame. So [Integza], …

Electric Jet Engine Uses 3D Printed Compressor, Skips The Turbine Altogether.

Turbojet engines are an incredible piece of 20th century engineering that except for some edge cases, have mostly been replaced by Turbofans. Still, even the most basic early designs were groundbre…

The Air Multiplier Fan Principle, Applied To A Jet Engine

Many readers will be familiar with the Dyson Air Multiplier, an ingenious bladeless fan design in which a compressor pushes jets of air from the inside edge of a large ring. This fast-moving air dr…

Turbocharger Jet Engine Relies On Wood Pellet Ignition

Turbochargers as used on cars bear some similarities with jet engines. Fundamentally, both contain a turbine that harvests energy from hot gas, using it to spin a compressor which sucks in fresh ai…

Tesla Model S Gets Boost With Jet Engine Upgrade

Tesla is well known for making cars that can accelerate quickly, but there’s always room for improvement. [Warped Perception] decided that his Tesla Model S P85D needed that little bit of ext…

Roller Skating, Wile E. Coyote-Style

They say you learn something new every day, and they’re usually right about that. Today’s tidbit is that just anybody (including [Ian Charnas]) can exchange money for jet engines, no qu…
