Sneaky Owls Use Stealth And Fly Silently
2012-11-20 15:58:27

Alan McStravick for redOrbit.com — Your Universe Online Researchers are learning about stealth technology from a famous winged inhabitant in nature. Would you like to know just who-who they are taking their lead from? If you guessed the owl, well the “who” clue wasn´t exactly the most difficult. The reason they are looking at the owl is for its ability to fly silently. It is able to do this because of the natural design of its plumage, which aids in noise...

Aircraft morphing, especially in the case of the variable camber airfoil, has potential from the viewpoints of both fundamental aerodynamics and flight application. In the field of aerodynamics, the use of a variable camber airfoil can improve aircraft flight performance and allow efficient multiple missions; in biology, the concept of the variable camber airfoil can be employed to explain the mystery of animal flight. In the case of low-speed aircraft, the performance of...

Bats Save Energy By Drawing In Wings On Upstroke

[ Watch the Video ] Whether people are building a flying machine or nature is evolving one, there is pressure to optimize efficiency. A new analysis by biologists, physicists, and engineers at Brown University reveals the subtle but important degree to which that pressure has literally shaped the flapping wings of bats. The team's observations and calculations show that by flexing their wings inward to their bodies on the upstroke, bats use only 65 percent of the inertial energy they...

NASA-selected student teams will test their science experiments in the 2.2-second drop tower at NASA's Glenn Research Center in Cleveland from March 15-20. While in free fall, the students' experiments will experience microgravity conditions similar to those on the International Space Station. The selections are part of two national science competitions: Dropping In a Microgravity Environment (DIME) for high school student teams and What If No Gravity? (WING) for student teams in fifth...

Why don't you ever see baby pigeons? For the same reason you don't see many chicks: they can't fly. It can take months for their partially developed wings and flight muscles to become airworthy, and by then the youngsters are almost fullygrown. However, long before their maiden flight, pigeon chicks probably put their developing wings to use, flapping as they run up steep branches. Brandon Jackson from the University of Montana, USA, explains that Ken Dial and his son first noticed this...

Wang's research team discovered the sandwich microstructure of dragonfly wing veins [Wang et al. Compos Sci & Technol, 2008; 68: 186-192] and recently revealed the organic junction between these longitudinal veins and membranes of the dragonfly wing [Chen and Wang et al. Chinese Sci Bull, 2011; 56: 1658-1660]. Based on observed microstructural model and previously reported model about the main longitudinal veins and membrane, in which the former is based on the tubular model with sandwich...

In the future, tiny air vehicles may be able to fly through cracks in concrete to search for earthquake victims, explore a contaminated building or conduct surveillance missions for the military. But today, designing the best flying mechanism for these miniature aerial machines is still a challenging task. Creating micro-scale air vehicles that mimic the flapping of winged insects or birds has become popular, but they typically require a complex combination of pitching and plunging motions to...

Engineers in California and South Africa envision more fuel-efficient design Airplanes do not look much like birds -- unless you were to imagine a really weird bird or a very strange plane -- but should they? This question is exactly what a pair of engineers in California and South Africa inadvertently answered recently when they set about re-thinking the ubiquitous tube-and-wings aircraft architecture from scratch in order to make airplanes more fuel efficient. The modern airplane design...

Word of the Day
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
