In 2023, Sierra Space announced the VR35K-A had completed engine component testing, which allowed the company to advance to the full engine hot fire testing campaign. Next, Sierra Space will continue ...

An energy startup company called Vortex Bladeless has come up with a wind turbine design that doesn’t incorporate blades and it’s like nothing we’ve ever seen before. The revolutionary unit looks like ...

A vortex that forms at the tip of a turbine blade due to the pressure difference between the pressure and suction sides, leading to aerodynamic losses. Squealer Rim: A design feature on turbine ...

EPFL researchers have designed flexible, batlike wings that boost lift and improve flight performance. This innovation could lead to more efficient drones or energy-harvesting technologies.

a study on low specific speed Francis turbines found that localized erosion patterns were influenced by the continuous interblade vortex and flow instability, particularly during off-design ...

In the second of the two-part turbine series, Titan Enterprises shares the five critical design features for Pelton wheel ...

Unlike birds and insects, bats have flexible wings made of a thin membrane, allowing them to fly more efficiently. Inspired ...

Fighting fire usually involves water or foam, but they can be messy and environmentally destructive. Engineers at Ohio State ...

Miles above the Earth, two bands of fast-moving air – the polar jet stream and the stratospheric polar vortex – sometimes tango together to influence weather in the northern hemisphere.
