stream Here's a video that shows a 3 ft piece of balsa turned into a maple seed using only modeling clay. The study of maple seed aerodynamics has fascinated those in search of improving the current technological efficiencies and engineering fields have often mimicked the mechanics produced by evolution in an attempt to achieve equally high efficiencies. [The following is an exact transcript of this podcast.]. --- Methodology - A semi-empirical method is developed that provides a ratio stating how much longer a seed falls in air compared to freefall. Inspired by helicoptering tree seeds, aerospace engineers have finally cracked a 60-year old engineering aviation challenge: to create an aircraft that copies the seemingly simple, yet effective, aerodynamic flight of a maple seed. Maple seeds are primarily gyroscopically stabilized, so forget about all the aero stability suggestions, they don't matter here. "Maple seeds could represent the most basic and simple design for a miniature helicopter, if the swirling wing could be powered by a micromotor," says Lentink. However, careful design approaches by humans used in conventional design philosophy limit Aerodynamics and right-left symmetry in wind dispersal of maple, dipterocarps, conifers and some genera of apocyanaceae and magnoliaceae. optimisation in practical aerodynamics. A study in the journal Science shows that maple seeds generate lift as they slowly whirl to the ground. Each samara contains a single seed attached to an asymmetrical wing-like projection that, through a complicated aerodynamic process, causes the seed to spin rapidly as it falls, resembling a helicopter propeller. Now she's working with University of California engineer Christopher Viney to design a device that could be used to drop relief supplies from an airplane, using the aerodynamics of a falling maple seed. Keywords: Apocyanaceae, dipterocarps, magnoliaceae, maple, plant handedness, seed aerodynamics. are called samaras, but kids of all ages call them helicopters. The mechanism that causes maple tree "helicopter seeds" to spin has been a mystery, until now — a new study has found that the aerodynamics that … Maples make those little whirlybird seeds you see spiraling down in droves each spring. The Mapleseed project is developing a passive (i.e., free-falling) wireless in-situ sensor platform for use in detailed sensing of various properties of Earth’s atmosphere. Here is an index of aeronautics activities. Maple seed aerodynamics explained: Video: Maple Seeds Ride Self-Generated Tornadoes Samara: Steerable paper planes and maple seeds the basis for life-saving, disposable UAVS Samarai: Lockheed Martin's Samarai monocopter - you won't believe how this thing flies The maple seed geometry for the CFD simulation was created in Caedium Professional.

However, if located near the terminal end of the wing, i.e., maple and ash seeds, they all inevitably experience rotation during fall. 2361 0 obj <> endobj Which explains why the acorn might not fall far from the tree, but maple seeds can really go the distance. Single-rotor helicopters have been built and flown successfully with wing spans of roughly a meter, but never at the scale of a maple seed. The study appears in the June 12th issue of the journal Science. Purpose - The paper presents a theoretical framework that describes the aerodynamics of a falling maple (Acer pseudoplatanus) seed. A wide variety of classroom activities involving aeronautics have been developed by active teachers, educators, and NASA engineers and scientists for the NASA Glenn Learning Technologies Project during 1996 and 1997. Scientists filmed maple seeds as they wafted through a smoke-filled wind tunnel. The design thrust (3N) and solidity (0.12) are kept same for both propellers. A crude analogy with autorotation of a wind turbine suggests that the torque due to the aerodynamic force would initiate the gyration of the seed. They just study the aerodynamics of different seeds and report that the generation of a vortex at the leading edge of these seeds increases their … There are, however, some cases when drag is beneficial, such as with parachutes, for example. Depending on the species, maple trees flower in spring to early summer, and female flowers give rise to the samara. Purpose - The paper presents a theoretical framework that describes the aerodynamics of a falling maple (Acer pseudoplatanus) seed. This leading-edge vortex lowers the air pressure over the upper surface of the maple seed, effectively sucking the wing upward to oppose gravity, giving it a boost. Maple Seed Flight Aerodynamics. Maple seeds are one of those natural wonders that feature a nearly perfect design. �O�3�Lh/p���?� ������e6r-. Maple seeds were the inspiration for Olivia's winning idea in last year's Kids' Science Challenge. 3.Drop each "maple seed" from a height of at least 5 feet and watch its fall. So it seems that plants and animals have both stumbled on the same aerodynamic approach to battling gravity. In fact, scientists are using what they’re learning from these flying seeds to develop micro flying machines and even tiny helicopters that can be used for space exploration or to learn more about the atmospheres of planets like Mars. Subscribers get more award-winning coverage of advances in science & technology. And they found that a spiral of air develops on top of each falling seed’s wing.

A swirling maple seed generates a tornado-like vortex that sits atop the front leading edge as the ‘helicopter’ spins slowly to the ground. When located in front of the seed’s aerodynamic center, the seed exhibits a glider type translation during fall, without any rotation [3]. Notes. When located in front of the seed’s aerodynamic center, the seed exhibits a glider type translation during fall, without any rotation [3]. A crude analogy with autorotation of a wind turbine suggests that the torque due to the aerodynamic force would initiate the gyration of the seed.

That vortex generates lift, and acts like a miniature tornado that sucks the seed up. A piece of paper with a "wing" design (similar to that of a maple seed) or a bunch of individual streamers (like a dandelion seed), however, will fall more slowly and be blown farther by the fan.
