Researchers Create Jet Fuel Compounds From Fungus

Washington State University researchers have found a way to make jet fuel from a common black fungus found in decaying leaves, soil, and rotting fruit. They used Aspergillus carbonarius ITEM 5010 to create hydrocarbons, the chief component of petroleum, similar to those in aviation fuels.

NASA Tests Green Aviation Technology

Two NASA experiments designed to help reduce fuel consumption and emissions will fly this spring on a specially outfitted Boeing 757 airplane called the ecoDemonstrator. One includes 31 small devices that will blow jets of air on the vertical tail, and the other involves non-stick coatings to help repel bugs from the leading edge of wings. Both are designed to improve the air flow over the surface and ultimately reduce drag.

Airflow Model Could Reduce Time on the Tarmac

New research could lead to more efficient takeoffs on airport runways and improve safety. A mathematical tool was developed to calculate the flow of turbulent air produced by a plane’s wing tips — known scientifically as wing-tip vortices — when an airplane takes off. The study will assist in improving the present standards for the separation distance between planes, while maintaining safety. Mathematically calculating the amount of turbulence created by the wing tips of aircraft, particularly during takeoff, gives air traffic controllers a better method of determining how far each aircraft should be from the next.

Fundamentals of Heat Pipes: Theory, Design Applications

With increased power requirements and reducing packaging size, thermal management is critical for to ensure optimum performance of key electronics in military, medical and other commercial applications. Heat Pipes, which are ‘super conductors’ of heat, are now being more frequently utilized to solve these challenging heat issues. Although heat pipes have been around for decades, many new applications for them continue to emerge.

Accelerating the Aircraft Icing Certification Process Using Simulation

Icing on aircraft surfaces, appendages, sensors and its impact on aircraft engines is a safety critical aspect of aircraft design that impacts the whole supply chain. Achieving regulatory certification is a complex and time consuming process involving simulation, icing tunnels and flight testing. Recent regulatory changes and industry focus around high altitude ice crystals and Supercooled Large Droplets have further challenged the design process and the time to market for new aircraft and technology.

Computer Cooling System Could Save $6.3 Billion a Year in Electricity

A patented passive cooling system for computer processors from the University of Alabama could save U.S. consumers more than $6.3 billion per year in energy costs associated with running their computer cooling fans. The system uses convection to circulate 3M's Fluorinert FC-72 electronic cooling liquid through channels in a computer's processor, and then into a heat sink that serves as an external radiator.

Molecules Could Harvest Sunshine for a Rainy Day

The Sun is a huge source of energy. In just one hour, planet Earth is hit by so much sunshine that humankind could cover its energy needs for an entire year if only we knew how to harvest and save it. A student at the University of Copenhagen has researched his way to a breakthrough that may prove pivotal for technologies trying to capture the energy of the Sun, and saving it for a rainy day.
