Mazda’s rotary engine is coming back in the spotlight, but this time it’s not just a nostalgic callback to the RX-7 glory days. Instead, it’s quietly shaping the brand’s electrified future. Rather ...

Insufficient power grid support for wind turbines has become evident as wind energy use rises, particularly with bigger turbines. This paper introduces a modeling approach for a dual-rotor machine.

This week's Japan Mobility Show isn't just an auto show; it's a technological show of force. Japan's automakers, long accused of dragging their heels in the race to battery electrification, are here ...

The internal structure of many aero-engines is designed with a dual-rotor system. Up to now, there have been few studies on the influence of aerodynamic excitation on the dual-rotor system. The ...

Usually when we think of multicopter drones, we picture aircraft with four or more rotors. The V40 agricultural drone takes a different approach, using two tilting two rotors in an effort to improve ...

The Kaman K-MAX has intermeshing rotors eliminating the need for a tail rotor. These opposite-spinning rotors lend the K-MAX a natural tendency to hover, making it more stable. The K-MAX is ideal for ...
