Rotating detonation rocket engines work differently than traditional rockets to maximize thrust while using less fuel—an ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

Late last year, Safran completed a ground-test campaign with a full-scale counter-rotating open rotor (CROR) engine on an impressive outdoor testbed, almost 10 years after the launch of the ...

From a thermodynamic point of view, detonations are more efficient than the more commonly known deflagration (classic combustion). While classic combustion in rocket engines takes place at constant ...

GE Aviation and NASA will run a wind tunnel test program over the northern summer to evaluate and test counter-rotating fan-blade systems for open-rotor jet engine designs. The newly improved rig for ...

Today, we explore the Birotary Engine, a unique creation that merges the features of piston and rotary engines. This video explains how the Birotary Engine works, discussing its benefits and drawbacks ...

Dan Gurney, a famous racer from the 1970s, came back under the spotlight with a patent for a new type of engine. The legendary driver, who was known for his unusual height and the “bubbles” that the ...

Counter-rotating wind turbines (CRWTs) represent an innovative paradigm in wind energy conversion, employing a dual rotor mechanism in which two coaxial rotors spin in opposite directions. This ...

Yesterday, Vladimir Putin presented his country with a belated Christmas present: the Avangard hypersonic missile. According to Russian media, it's capable of reaching Mach 20. And if its ability to ...
