WHAT IS AN ARBORLOO?• Ecological outhouse• Pit dug & supports in place• Arborloo set up• Arborloo removed &tree
planted• Combat deforestation in
Haiti

• Wind resistance during Type I hurricanes• Test collapsibility of arborloo• Ensure safety in case of dislodgement• Why is this a Senior Design project?• Engineering skillset required to ensure all objectives are met
– CFD, Force Analysis, Safety Engineering, Modeling, Cost Efficiency• Set foundation for which all future arborloo designs can be
tested off of
WHY IS THE STAND IMPORTANT?

The primary objective of this project is to design a scale model and a full-size test stand that will help determine the wind resistance of various arborloo designs. The scale model test stand should replicate the forces experienced by a Class I hurricane, and the results should be easily comparable to the lower speed, full-size results. Both test stands should allow for safe testing of various arborloo sizes, shapes, and materials.

Deliverables:• Scale model and full-size test
set-up and procedure• Test Plan • Means of comparing results
from scale model and full-size testing
• Design drawings and Bill of Materials
• Assembly instructions • Clearly documented test results
Objectives/Scope:• Determine the appropriate
fluid and scale needed to replicate a Class I hurricane
• Design a test stand than can be used for multiple different arborloo designs and configurations
• Demonstrate reliable and repeatable results
PROJECT SUMMARY

Assumptions & Constraints:• Budget: $800• Scale model must utilize
existing fluid flow analysis equipment in KGCOE, while keeping current set-ups intact
• Test stand must protect surrounding people and infrastructure from flying debris
Expected Project Benefits:• Arborloo designs can be
tested to find the optimal design to be used in Haiti
• Test stand can be used by other senior design groups to evaluate their arborloo designs

• Software– Modeling arborloo designs with
CFD software• Sensors
– Using and collecting data from sensors
– Determining appropriate sensor types
Issues & Risks:• Project Understanding and
Digesting By Team– Understanding of Class I
hurricanes– Determining critical locations to
measure moment and forces • Available Resources
– Obtaining Resources– Order Parts/Hardware– Lead Time
