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

planted• Combat deforestation in

Haiti

5

• 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?

6

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.

PROJECT STATEMENT

7

• Create test rig & procedure for scale testing

• Simulate Type I hurricanes• Measure wind speed, forces• Create test procedure for full

size testing• Recommendations for future

design of arborloos

PROJECT STATEMENT

8

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

9

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

PROJECT SUMMARY

10

• 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

PROJECT SUMMARY

11

• Demonstrate reliability and repeatability

• Simulate wind speeds and forces of a Class 1 hurricane

• Protect users and bystanders while testing

• Protect other infrastructure and equipment from damage

• Allow for different shapes and materials to be tested and compared

• Allow for different weights and centers of gravity to be tested and compared

• Utilize existing equipment while keeping current set-ups intact

• Be creative in a manner for compact storage

• Provide easy to read instructions on how to assemble and use in a safe manner

• Is low cost (Budget <800)• Can be set up by 2 people• Can be set up and taken down

quickly• Long lifespan
