Engineers, zoologists reveal how gulls 'wing morph' for stable soaring

Aviation experts and zoologists have provided new insights into how gulls configure their wing shape -- known as wing morphing -- to stabilize their flight. The findings could be used to design more efficient flying vehicles, including soaring drones for farming or environmental more

Understanding dynamic stall at high speeds

Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed understanding, researchers took a deep dive into the physics of dynamic stall so that it can be used beneficially and reliably by more

Upwind wind plants can reduce flow to downwind neighbors

New research highlights a previously unexplored consequence of the global proliferation of wind energy facilities: a wake effect from upwind facilities that can reduce the energy production of their downwind more

How plants can generate electricity to power LED light bulbs

Researchers have discovered that living plants are literally 'green' power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an 'hybrid tree' made of natural and artificial leaves can act as an innovative 'green' electrical generator converting wind into more

Engineers fly first-ever plane with no moving parts

Engineers have built and flown the first-ever plane with no moving parts. Instead of propellers or turbines, the light aircraft is powered by an 'ionic wind' -- a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady more

Making wind farms more efficient

With energy demands rising, researchers have completed an algorithm -- or approach -- to design more efficient wind farms, helping to generate more revenue for builders and more renewable energy for their more

Magnetic pumping pushes plasma particles to high energies

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic more

Opening communication lines between propulsion and airflow poses new questions

On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers have gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the more

Windier wind farms

Depending on how wind turbines are situated relative to each other and to the prevailing wind, those not directly in the path of the wind could be left to extract energy from significantly depleted airflow. However, according to researchers, there are ways to get around this issue of diminishing wind more

Large-scale US wind power would cause warming that would take roughly a century to offset

Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing US electricity emissions to zero with solar. Researchers report the most accurate modelling yet of how increasing wind power would affect climate, finding that large-scale wind power generation would warm the Continental United States 0.24 degrees Celsius because wind turbines redistribute heat in the more
