Essay on Testing Aerodynamic Structures for Our Science...

First, aerodynamics is the study of the motion of the air. Aerodynamics consists of 4 variables, which is thrust, gravity, lift, and drag. (Tennekes,H, 2009) Aerodynamics has to do with almost everything dealing with air of course.(Tennekes,H ,2009) For example, it can be air crafts, it can be wings, it can be birds, it can be a race car. Birds need aerodynamics so they can glide in the air so they can also gain enough speed to catch prey. Like a hawk swooping down 70 miles an hour to get a mouse to eat. Race cars need aerodynamics so that the car structure can have the most air resistance it wont apply as much pressure onto the car. Like birds air crafts also need aerodynamics for the wings on the aircraft or the weight of the aircraft.†¦show more content†¦They have to deal with aerodynamics everyday since they are the scientists who works everyday trying to make aerodynamic rockets to study space, they have to be very precise when ever they make a rocket, it can take year s, because one time NASA sent a rocket but as soon it hit a certain altitude it exploded because of on of the cables inside wasn’t connected. (NASA,2013) Plus NASA is also creating aircraft for the future so they can send regular people into space to experience how it would feel like to go into space, but the trip would cost over 3 million dollars, so you would only be allowed to get on if you are a millionaire or higher. (NASA,2013) Lift is a force pushes the object up ward. Drag is related to air resistance, drag is like friction but like in the air. Drag is a force that causes to pull the object the opposite way, for example if you put your hand out a window of a car and the car is on the high way, and if you make your hand like a wall and put it out in the air it would pull your hand back wards. (Paper Airplanes HQ 2013) But if you put your hand flat down it would just let your hand pass through since its allows air to go around the hand causing little drag. Thrust is a f orward force which allows the object to go into the air, for example when you have a paper airplane and throw it, that throw with your arm is the thrust for the airplane to launch.(Auld,D.J.

That second factor is critical, Rance explains, because If you have a big chest or a big behind sticking out, you are less hydrodynamic. It s like diving in the water in a big woolly jumper. To reduce hydrodynamic drag, Aqualab began testing some 60 fabrics, with the help of a NASA wind tunnel, before coming up with a model made of extremely fine yarn that is densely woven together. This was slathered with nanomolecular plasma and on top of that, a Teflon-like coating, to make the surfaceRead MoreSpeedo Innovation5178 Words   |  21 Pagesthe water.

I think this may even be my best book. The new Google and Starbucks cases should arouse keen student interest, and may even inspire another generation of entrepreneurs. A fair number of the older cases have faced significant changes in the last few years, for better or for worse, and these we have captured to add to learning insights. After so many years of investigating mistakes, and more recently successes also, it
