Nature Inspired Inventions and Engineering for Aviation

Humans have long been inspired by observing nature. Leonardo Da Vinci sketched several designs of potential flying machines based on the observation of birds.
Aviation technology has made dramatic changes since the first flight of the Wright Brothers.  Engineers now look back to the masters of the natural world to find clues for amazing breakthroughs in aviation design.  The following are just a few of the nature inspired improvements in aviation engineering and technology:
Morphing Wings
Birds and insects are able to adjust their wing size and shape while they fly. They have skeletal and vascular structures that morph into different shapes in order to compensate for the ideal conditions needed to maneuver effectively in the air. Engineers are experimenting with several creative designs that mimic the birds to adjust the wings of  aircraft in order to fit every stage of the flight mission.

Perching
When birds come in for a landing, they execute a series of maneuvers and adjustments that allow them to make extremely accurate stops on difficult perches.  Birds do not use the standard, linear landings made by most aircraft. Engineers are testing how to recreate bird-like adjustments in speed and direction to help aircraft land safely and accurately.  The aircraft of the future may not need runways or brakes!   Bird morphing wings and perching behaviors  that are influencing aviation design are discussed in the 2011 abstract by Elvin Pineda from the University of Massachusetts.

Winglets from Outstretched Eagle Wings
The wing-tips of Eagles and other birds have also caught the attention of several aviation engineers.  Several airplanes have been designed with adjustable wingtip mechanisms. This allows the aircraft to make slight adjustments to their wing tips to reduce the drag of the aircraft and improve efficiency and handling characteristics as well as enhance safety for following aircraft without increasing the wingspan. This also provides an increase in lift generated at the wingtip by smoothing the airflow and reducing the lift induced drag . The increased efficiency and reduced drag also improves fuel efficiency.
Lightweight Superstructure
The skeletal structures of bees and butterfly are extremely strong and light weight and able to form different shapes to allow the creatures to flutter from one flower to the next with great maneuverability and ease.  Engineers are examining designed aircraft using similar patterns that mimic the shapes and curves of bees and insects.  Birds also have well designed beaks and facial features that are being studied by engineers in order to make more aerodynamic designs.  These designs have also proved to be incredibly durable.

Shark Skin

Flying creatures are not the only natural teachers that are schooling modern aviation engineers.  Sharks have a groovy skin that allows them to glide through the water with the greatest of ease.  Engineers copy these grooves in the hull design of aircraft in order to reduce wind drag and increase speed and efficiency.

Noise Reduction

Engineers are on a constant quest to reduce airplane noise.  A number of creatures are giving lessons on how to keep the flying machines from disturbing the peace.  The pistol shrimp emits a loud crack sound to stun prey and confuse predators while tuning the frequency out of his own brain.  Bees position their honeycombs in a certain way to dampen sound. Owls are experts of stealth and silent flight.  Engineers are also taking a close look at creatures such as cicadas, butterflies, and fish to provide some insight on how to develop potential noise reduction technology.  Some of the ideas include retractable brush fringe and serrated  engine casings.

These are just a few ways of how engineers are looking to the time-tested methods of the natural world to design the flying machines of the future. That is the reason why companies like Boeing and Airbus are sending their engineers off on outdoor adventures to examine the genius of the natural world.  It just makes sense to take flight lessons from those that have been doing it for thousands of years!

What is Environmental Education by Definition?

There are many definitions for environmental education depending on where you look.

Although definitions may vary, there seems to be some common agreements to what it is and what it should be.

Environmental education is often thought of when teaching about the environment and conservation.  Sometimes it is referred to as experiential learning outside and may include things like outdoor classrooms, outdoor adventures, and outdoor recreation.  It also often refers to learning about natural processes in the classroom.

This video is a compilation of various definitions of environmental education from some leading organizations and authorities.

Mullusc superglue

So if mussels and acorn barnacles can attach to to the side of rocks and concrete pilings and be able to withstand powerful tidal flows and waves of salt water, why can’t we make a glue that can do the same?  Well that is just what scientist are doing now. They are trying to figure out the chemical structure of the that  extremely powerful mullusc glue to use for practical human applications.

Velcro

 

Velcro

In 1948 a Swiss electrical engineer named George de Mestral came up with the idea for velcro  when he was hunting in the Alps and began to examine the burrs sticking to his clothes from burdock.  He noticed the hundreds of hooks  when he examined the burrs under a microscope.  After several years of trial and error, he managed to come up with the design we know today and commercialize it.

Natural Science: Herbs and Spices Anticancer Potential

 

640px-Thyme-Bundle

 On the Scientific Discovery resource page, you can find some of the top websites with some fascinating scientific breakthroughs using the nature method.

The International Journal of Science and Nature has found that Herbs and Spices have anticancer potential.

The study of plants and herbs to find treatments for various illnesses and ailments has been a common practice of many cultures for generations. When European settlers in the New World would fall ill, they often would seek out Native American medicine man with his satchel of herbs to find a quick cure.  The Chinese have been doing this for years.

Although much of the herbal knowledge of ancient civilizations has been lost, many of the medicinal qualities of plants are now being proven by modern science.

As our bodies age and are increasingly exposed to carcinogens from the environment that attack our immune systems, our bodies become more susceptible to cancer cells.

The biotech industry has been conducting a great deal of research to find medicines with cancer fighting properties.

Research has shown that a diet rich in antioxidants can help to remove damaging agents known as  “free radicals” from the bloodstream and reduce the risk of cancer.

In a study from 2004-2012 published in the Journal of the Society of Science and Nature, several herbs and spices were tested for anticancer potential including: Leeks, Lemon, Lemongrass, canopy, pepper, indian borage, ginger, and onions,

The conclusion found that the samples ginger, oregano, and tabon tabon showed a high value of phytochemicals and antioxidants and high anticancer potential.

There is so much that we could learn from the study of plants.

 What other treatments are waiting to be discovered out in nature?
