Beginner's Guide to Aerodynamics

Beginner's Guide to Aerodynamics
At this Web site you can study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance; the three forces (lift, drag, and weight) that act on a glider; and finally, the four forces that act on a powered airplane. Because aerodynamics involves both the motion of the object and the reaction of the air, there are several pages devoted to basic gas properties and how those properties change through the atmosphere. This site was created at NASA Glenn as part of the Learning Technologies Project (LTP). It is currently supported by the Aeronautics Research Mission Directorate at NASA HQ through the Educational Programs Office at NASA Glenn. There is a special section of the Beginner's Guide which deals with compressible, or high speed, aerodynamics.

Aerodynamics Experiments to Share With Your Kids This article teaches kids about aeronautics and gives a handful of totally fun activities to experiment with for their homeschool science learning (including helicopters, parachutes, and other flying machines). It's also good for boy scouts working on a badge, or for any kids that love science experiments. These experiments are part of a homeschool science program that I teach, and I promise your kids will love it. Every flying thing, whether it's an airplane, spacecraft, soccer ball, or flying kid, experiences four aerodynamic primary forces: lift, weight, thrust and drag. An airplane uses a propeller or jet engine to generate thrust. The wings to create lift. Scientists discover most accurate clocks in the universe Time in space has always been an elusive issue for scientists who have long struggled to find a constant standard. But a new discovery may help us understand time as never before. Space.com reports that scientists are now using pulsars — rapidly spinning stars that pulse over time — to tell the universe’s time. This is due to a recent revelation about how pulsars function and rotate.

35 Years at the National Air and Space Museum When I began to work at the National Air and Space Museum in March 1975, I was the Museum’s sole reference librarian, having graduated from Catholic University of America with an M.S. in Library Science the previous year. I had only been working for a few weeks, when I was told that we’d be moving from our Arts and Industries Building location to a brand new facility down the street. My boss, a professional of some standing in the librarian community, knew her job well, but she didn’t know much about moving a library, so it was up to me and one of my stalwart colleagues, a guy named Bill Jackson, whom some old-timers will remember fondly, to figure out how to box everything up and move it less than a city block away.

Lifting SAM Instrument for Installation into Mars Rover Lifting SAM Instrument for Installation into Mars Rover The Sample Analysis at Mars (SAM) instrument, largest of the 10 science instruments for NASA's Mars Science Laboratory mission, will examine samples of Martian rocks, soil and atmosphere for information about chemicals that are important to life and other chemical indicators about past and present environments. NASA's Goddard Space Flight Center, Greenbelt, Md., built SAM. The 40-kilogram (88-pound) instrument includes three laboratory tools for analyzing chemistry, plus mechanisms for handling and processing samples. In this photograph, technicians and engineers inside a clean room at NASA's Jet Propulsion Laboratory, Pasadena, Calif., prepare to install SAM into the mission's Mars rover, Curiosity.

Properties of Air Photo Credit: Clipart.com Purpose To demonstrate that air takes up space, and puts pressure, or pushes, on everything around it. Context Beam Me Up, Scotty! Scientists Teleport Info 10 Miles - Scientists manage to teleport information nearly 10 miles with unprecedented precision. - The team used quantum entanglement to teleport the information. - The feat could lead to a global, impenetrable communication network and powerful quantum computers.

Ten things you don’t know about black holes Well, they’re black, and they’re like bottomless holes. What would you call them? -Me, when a friend asked me why they’re named what they are Ah, black holes. The ultimate shiver-inducer of the cosmos, out-jawing sharks, out-ooking spiders, out-scaring… um, something scary. But we’re fascinated by ‘em, have no doubt — even if we don’t understand a whole lot about them. 25 Beautifully Illustrated Thought-Provoking Questions A question that makes you think is worth asking… At the cusp of a new day, week, month, or year, most of us take a little time to reflect on our lives by looking back over the past and ahead into the future. We ponder the successes, failures and standout events that are slowly scripting our life’s story. This process of self reflection helps us maintain a conscious awareness of where we’ve been and where we intend to go. It is pertinent to the organization and preservation of our dreams, goals and desires.

Preliminary Design Overview This Overview page for the Preliminary Design Phase contains the following sections: Overview The preliminary design phase may also be known as conceptual design or architectural design . During this phase, the high-level design concept is created, which will implement the complex electronics requirements.
