The F-47’s adaptive cycle engine can reconfigure itself in flight, shifting airflow to balance extreme efficiency, Mach 2+ thrust, and reduced heat signature. In this breakdown, we explain the three ...

Ever since 2016, the U.S. Air Force (USAF) has been looking for a new engine to slap into its fifth-generation F-35 fighter plane. The engine didn’t get to be detailed until 2019, and testing didn’t ...

It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

The Lockheed Martin F-35 Lightning II is one of the few fifth-generation military aircraft currently in operation. Compared with all the others still flying in the world, it’s a true junior, having ...

GE Aviation’s (NYSE: GE) XA100 adaptive cycle engine is ready to progress from prototype into development following testing with the U.S. Air Force, according to the manufacturer. The XA100, along ...

The four-stroke engine has dominated internal combustion for more than a century, but a British engineering firm is ready to topple that technology with what it calls a 150-horsepower "five-stroke" ...

Years ago, the choice was clear: When it came to 2 stroke vs 4 stroke outboard motors, 2 stroke won every time. Two stroke motors offered a better power-to-weight ratio, were cheaper to manufacture, ...

Variable cycle engine design embodies a transformative approach in aero‐propulsion, enabling engines to adapt their thermodynamic cycle to meet diverse operational demands, from fuel efficiency to ...

If you’re shopping for a new fishing boat or an outboard motor to power it, one of the decisions you’ll have to make is between a 2 stroke vs 4 stroke engine. Unless you’re going electric, this choice ...

The 2018 Volkswagen Tiguan doesn’t look like a front-running candidate to tackle an off-road course. It’s a family crossover designed to combat asphalt parking lots and stop-and-go traffic in the ...

Two-stroke engines were phased out by tough pollution laws and fuel economy targets, but they could be making a comeback with KTM, Honda and boutique builders. KTM and Honda have both registered ...
