Project Overview

• Design a Dual-Bore Oil Debris

Monitoring (ODM) System

○ Used in both commercial and military airplanes ○ Detects ferrous and non-ferrous material within turbine ○ Monitors wear and tear

• Provides an alert/warning of failure of

mechanical components

○ Gears, bearings, pumps, & etc.

Problems with Current Single-Bore Design

• Unable to detect smaller debris

○ When Bore size is increased ■ Pressure decreases ■ Size of particle detection decreases

○ When Bore size is decreased

■ Pressure increases

■

Size of particle detection increases

Requirements & Specifications

• ODM sensors in parallel
• Study magnetic field interactions

○ Characteristics of dual bore ○ Sizing, and configuration

• Design and build the Dual-Bore ODM system

○ Ability for particle detection ○ Optimize the design of a multi-bore ODM System Configuration ○ Advanced indication of Component failure

• Build, Test and Analyze physical model

Constraints

• Issues with interaction between magnetic fields

○ How we combat the interaction: ■ Changing distance between ODM systems ■ One coil wound to the right the other to the left ■ Magnetic Shield in between the ODM systems

• Operation under extreme conditions
• Pressure in oil passageway

○ Large diameter required

Approach

• Build multiple magnetic field assemblies and configurations

○ Use of PVC Piping as flow passage ○ Use of different sizes copper wiring for the coils ○ Validate models ○ Optimal configuration

• Determine optimal coil placement to minimize or leverage

interference

Design Ideas

• Using Hall Effect Sensor
• Using Sensing Coil

Solution

Sensing Coil:

• Location is permanent

and allows accurate results

• Ease of ability to replicate

results

• Easily able to determine

the difference between just the inductive coil and the inductive coil with particles

• Less expensive

Physical Model Setup Sensing Coil Inductive Coil Inductive Coil

Hall Effect Sensor:

• Precise location of sensor

required to obtain good reading

• Inaccurate
• Difficulty telling the

difference between just the inductive coil and the inductive coil with particles

• More expensive

Next Steps

Single Bore:

• Optimizing detection strength of

the sensing coil by altering various variables ○ Wire Gauge ○ Number of Turns ○ Inside Diameter ○ Input Voltage ○ Input Frequency Dual Bore:

• Limiting interference between

each bore

• Using Dual Bore to detect a

particle passing through the coil setup

• Optimizing spacing and strength
• f each coil setup
