Harrison Bennett Joseph Thekkekkara Joshua LazaroJordan BoyleCreative Journey: Windshield Wiper System
EVX's ultimate vision is to make self powering cars the future of transportation.Windscreen Wiper System has not yet been created that is aerodynamic enough to contribute to an overall coefficient of drag < 0.21.
Explain what coefficient of drag is and its importance to a solar vehicle.Drag coefficient is RESISTANCE of an object in fluidic environment.2
Project Overview and ObjectivesCreate a windshield wiper system:Mounted onto the EVX Immortus vehicle and ready for use.Meets Australian Design RequirementsAerodynamically efficient (contribute to a cd < 0.21)Taking into consideration the actuator (weight, complexity, power consumption)
The history of the windscreen wiper. Why is a windscreen wiper needed?. Aerodynamics basics.Different kinds of Windscreen wiper, how people have approached clearing a windscreen.
Approach: Provide a brief description of the approach in your project, including necessary details on the relevant methods, theory, experimental processes and setups, and/or validation techniques.4
Why are Windscreen Wipers Needed?
Thinking Outside the BoxUltrasonic TransducersHigh Pressure AirHydrophobic Coating
Hiding the Blades
Mechanical Cover To encapsulate it- Redirect Air when up?No Cover May have issues regarding air-pockets9
Beam VS Conventional (Superstructure)
Blade Designs/ Ideas
Design MethodDetermine dimensions of Blade.Use calculations to calculate torque required to move blade.Define constraints of linkage size space .Select motor Linkage specs define motor requirements
