There are several patents around the superconducting turbo electric bypass machine that will enable more powerful engines to drive a mach 5 hypersonic commercial business jet. HyperMach new design has ...

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 ...

(Nanowerk News) Wind energy is one of the most promising renewable energy resources in the world today. Dr. Hui Hu and his group at Iowa State University studied the effects of the relative rotation ...

Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more ...

They're noisy, but your next missile or military vehicle might have an RDE (rotating detonation engine) powerplant in it. RDEs are more fuel-efficient, lighter, easier to maintain, and capable of ...

The search for renewable energy sources that are efficient and cost-effective has affected all sectors, and wind energy is no different. If we stop to think about current turbines, we will see that ...

Norwegian companies Norsk Hydro and World Wide Wind announced this week plans to use sustainable and recyclable materials such as aluminium in the construction of floating offshore wind turbines.

With around 430 gas-turbine engines on 129 of its ships burning about US$2 billion worth of fuel every year, the U.S. Navy is examining the potential of using Rotating Detonation Engines (RDEs) to ...

This file type includes high-resolution graphics and schematics when applicable. The GEnx turbofan engine currently powers the Boeing 747-8 and Boeing 787 Dreamliner. The engine, which is 15% more ...

Wind energy is one of the most promising renewable energy resources in the world today. Dr. Hui Hu and his group at Iowa State University studied the effects of the relative rotation directions of two ...
