Much like the calculus we use, aeronautical engineers use functions with velocity and acceleration to find if a plane will fly. What they do differently is that they use complex computer models to simulate every possible iteration of a wing to find what is perfect for a certain type of plane: jet, prop driven, passenger, private, and even military. It all comes down to basic functions similar to those we use in class every day. ]]> 2017-02-06 15:27:06 UTC https://padlet.com/peter_barron17/leg7igy2hq7a/wish/151850369 peter_barron17 https://padlet.com/peter_barron17/leg7igy2hq7a/wish/151852616 https://www.nasa.gov/audience/forstudents/k-4/stories/nasa-knows/what-are-wind-tunnels-k4.html

After extensive computer modeling designers test their designs in a wind tunnel. The math didn't end when the simulations stopped. Because the wind tunnel uses scale models, engineers must find the correct scale wind speed to test the aircraft design. First, they must find the max speed the aircraft can attain without shaking uncontrollably (as that would simulate a catastrophic failure) to do this they essentially move in in increments of wind speed until they reach the maximum. From then on they have to calculate the angles of attack (maximum angle a plane can reach on both the horizontal and verticle axis without losing "flow" over the wings. This is also known as stalling. By using math they can calculate the tests to find airworthiness. ]]> 2017-02-06 15:32:15 UTC https://padlet.com/peter_barron17/leg7igy2hq7a/wish/151852616 peter_barron17 https://padlet.com/peter_barron17/leg7igy2hq7a/wish/151855364 http://www.airbus.com/company/aircraft-manufacture/how-is-an-aircraft-built/

After testing is complete and the airframe is deemed safe and usable, production starts. After the designers design the outside of the plane to soar through the skies, other engineers must then find what parts can and can't be used based on strength and weight. This is again tested on a computer down to the millimeter. Once the materials are selected, CAD models are created and test on how to make the plane as cheap to make as possible for the manufacturer and as safe as possible for the rest of us. ]]> 2017-02-06 15:38:56 UTC https://padlet.com/peter_barron17/leg7igy2hq7a/wish/151855364 peter_barron17 https://padlet.com/peter_barron17/leg7igy2hq7a/wish/153616275 http://www.planeandpilotmag.com/article/airplanes-cars-whats-the-difference/
Although the demands of aircraft design and automotive design drastically differ there are many massive similarities. For example, aircraft use wind tunnel testing. Car manufacturers do the same. A difference, however, is that aircraft designers want their creations to leave the ground whereas car designers want their creations to stay on the ground. The testing is the same in principle. CAD models are used to design each part and the entire car (as mentioned below). ]]> 2017-02-14 03:24:29 UTC https://padlet.com/peter_barron17/leg7igy2hq7a/wish/153616275 peter_barron17 https://padlet.com/peter_barron17/leg7igy2hq7a/wish/153619937 https://www.autoevolution.com/news/automotive-wind-tunnels-making-aerodynamic-cars-23250.html

Much like aircraft cars are designed in wind tunnels. The same math used for calculating the drag of a plane are used in car design. Models are scaled down for testing just like with planes. Calc is used to graph the force and speed of the wind on the car as a product of the shape area and paint type of the car.

F=(0.5C)(ρ)(A)(V² ) is the equation used. C is the coefficient of drag. F is the drag force. V is the velocity. A is the reference area. ρ is the density of the fluid. This is a calculus equation much like those we use in class. It helps calculate how much drag a car will have acted on it at any speed on any surface.   ]]> 2017-02-14 04:00:28 UTC https://padlet.com/peter_barron17/leg7igy2hq7a/wish/153619937
