Exercise Four Deliverables (Concept Sketches and Team Sketch)

Bradley

 

The angle that the propeller is at will cause a variation in the design. Bradley found through research that when the propeller is tilted like this, the craft is more stable.  Also, in terms of how the lab is set up, there will be less frictional force on the wheels as they go over the rails, so it will be able to get from one point to another easier.  Bradley also centered the “arm” so the design is stable and not leaning to the left on the rail.

Emily

Emily’s AEV design has a flattened view with angled propellers similar to that of an airplane. Due to Emily’s research the aerodynamics of the winged ends causes faster movement due to less resistance put onto the body of the AEV.

Sarabeth

Sarabeth produced a design like this, with the motors parallel to each other and on the same side and a rectangular shape, because it be more stable in the air. This is also the most cost efficient design. If the AEV had a pointed tip, it would have to be reinforced with many materials since it would cut through air.  In using a lightweight design, it is crucial to take into account the product’s environmental 

impact, functionality, and manufacturability. High strength steel and composite plastic have taken over in today’s society as main lightweight design materials. Lightweight aims to reduce drag force and downsize. Material has to be durable, and the layout of the design must prevent air resistance the best that it can.  Aerodynamics is the study of forces and the resulting motion of objects through the air. Aerodynamics can be found in flying a kite above a park, throwing a beach ball at the beach, or even a rocket taking off from a space station. Aerodynamics incorporates both the motion of the object and incorporates the air. Air resistance (lift, drag and weight are also taken into consideration). Due to all these factor being accounted for, the design of objects in the air has changed throughout the years. The most optimal design for an object in the air is one that is lightweight, cuts through wind well, and has smooth sides.

Nick

 

Nick’s design incorporates two main features. The first feature is that the design does not have a large front facing surface to minimize air resistance. This makes the design easier to move. The next main feature is that the design only requires the minimum amount of material for the AEV to work. This leads to less weight and is therefore more efficient.
