Wind tunnel tests will help design future Army tiltrotor aircraft
7 Dec 2020 at 9:41am
After more than three years in development, a team of U.S. Army researchers and industry partners completed the construction of a testbed that will help to inform the design of future Army rotorcraft. The team plans to test the TiltRotor Aeroelastic Stability Testbed, or TRAST in a massive wind tunnel at the NASA Langley Research Center to gauge the effectiveness of modern tiltrotor stability models.
Proverbial wolf can't blow down modern timber high-rises

Researchers reveals how the microstructure of small finlets on owl feathers enable silent flight.
Moving wind turbine blades toward recyclability
17 Nov 2020 at 4:26pm
A new material for wind blades that can be recycled could transform the wind industry, rendering renewable energy more sustainable than ever before while lowering costs in the process. Researchers demonstrated the feasibility of thermoplastic resin by manufacturing a 9-meter-long wind turbine blade using this novel resin.
Smart devices to schedule electricity use may prevent power outages
10 Nov 2020 at 8:25am
Power plants generate electricity and send it into power lines that distribute energy to nodes where it can be used. But if the electricity load is more than the system's capacity, transmission can fail, leading to a cascade of failures throughout the electric grid. Researchers show demand side control may be an effective solution to stabilizing the reliability of power grids that use a mix of energy generation sources.
Tracking flight trajectory of evaporating cough droplets
3 Nov 2020 at 8:25am
Researchers conducted a numerical study on droplet dispersion using high fidelity air flow simulation. The scientists found a single 100-micrometer cough droplet under wind speed of 2 meters per second can travel up to 6.6 meters and even further under dry air conditions due to droplet evaporation.
Renewable energy targets can undermine sustainable intentions
28 Oct 2020 at 7:18am
Renewable energy targets (RETs) may be too blunt a tool for ensuring a sustainable future, according to new research.
Mathematical tools predict if wave-energy devices stay afloat in the ocean
13 Oct 2020 at 12:08pm
Ocean waves represent an abundant source of renewable energy. But to best use this natural resource, wave-energy converters need to be capable of physically handling ocean waves of different strengths without capsizing.
Generating renewable hydrogen fuel from the sea
29 Sep 2020 at 2:34pm
The power of the sun, wind and sea may soon combine to produce clean-burning hydrogen fuel, according to researchers. The team integrated water purification technology into a new proof-of-concept design for a sea water electrolyzer, which uses an electric current to split apart the hydrogen and oxygen in water molecules.
This tiny device can scavenge wind energy from the breeze you make when you walk
23 Sep 2020 at 9:47am
Most of the wind available on land is too gentle to push commercial wind turbine blades, but now researchers have designed a kind of 'tiny wind turbine' that can scavenge wind energy from breezes as little as those created by a brisk walk. The method is a low-cost and efficient way of collecting light breezes as a micro-energy source.
Evaporation critical to coronavirus transmission as weather changes
22 Sep 2020 at 8:23am
As COVID-19 cases continue to rise, it is increasingly urgent to understand how climate impacts the spread of the coronavirus, particularly as winter virus infections are more common and the northern hemisphere will soon see cooler temperatures. Researchers studied the effects of relative humidity, environmental temperature, and wind speed on the respiratory cloud and virus viability. They found a critical factor for the transmission of the infectious particles is evaporation.
California offshore winds show promise as power source
8 Sep 2020 at 2:05pm
One of the challenges of moving toward fully renewable energy in California by 2045 is matching production to demand. Consumer demand peaks in the evening when solar energy is no longer available. Offshore wind energy has the potential to help meet this demand.
