Just want to create a topic and compilations of articles regarding Biomimetics or the imitation of the models, systems, and elements of nature for the purpose of solving complex human problems. 

 

Problem: A JET plane in flight creates rapidly spiraling swirls of air at the tips of its wings. These vortices cause drag, increasing fuel consumption. They also buffet planes that may be following closely. Thus, flights departing from the same runway must be sufficiently spaced to allow time for the vortices to dissipate.

 

Jehovah's Creation: Winglets, inspired by the upturned wing-tip feathers of soaring birds, such as buzzards, eagles, and storks. 

 

Biomimetic Solution: Engineers have designed airplane wings with a similar shape. Using innovative wind-tunnel testing, they found that if the modified wings were precisely curved at the tip and properly aligned with the airflow, they improved aircraft performance—nowadays by up to 10 percent or more. The reason is that winglets minimize drag by reducing the size of the vortices. Moreover, winglets also create a form of thrust that counteracts some of the normal drag of the airplane.

 

Result: Winglets thus enable airplanes to fly farther, carry a greater load, have shorter wings—which also facilitates parking—and save fuel. In 2010, for example, airlines “saved 2 billion gallons [7,600 million L] of jet fuel worldwide.

Velcro was invented by George de Mestral in 1941 and was inspired by the burrs he found on himself and on his dog. Being an engineer and entrepreneur, Mr. de Mestral examined the burr under a microscope and realized the small hooks of the burr and loops of the fur/fabric allowed the burr to adhere exceedingly well.Oct 28, 2016
