ROI wiring

Introduction


ROI wiring is probably a new concept for everyone sitting here to day, but (attn getter) from the high tensile iron lines of the telegraph age to high voltage aluminum superconductors, our lives are wrapped up in wires. Ribbonized, Organized, Integrated wiring (ROI) is here to simplify it.

transition: Airplanes are no exception to the wiring mantra of the 21st century

Body

I. ROI and how its made vs. what its replacing.
A. Standard wiring harnesses
a. Composite of whats available and easy to use.
1. Individual sizes and gauges vary greatly
2. Substitutes may be used in and still maintain airworthiness
b. Bulky, labor intensive and hard to keep uniform (picture)
1. Certain wires/cables can not be routed together
2. Area may not allow for all cables to be safely routed
B. ROI harnesses and materials
a. ROI wires are mil spec and braided in ribbons (picture)
b. ROI incorporates advanced ideas concepts

Transition: Lets take the decision out of the mechanics hands so that all future harnesses will become easier to trouble shoot and maintain.

II. Why ROI is better
A. Characteristics
a. EEE performance and advances
1. Cross talk and interference problems
2. Uniform cross section and trouble shooting
B. Ease of use
a. Coding of the wires and pins
1. Each wire has a color, letter, and number
2. All circle connectors will be have standard input holes that will match standard ribbon layouts (picture)
b. Wired according to destination as apposed to systems
1. Airplanes are normally wired system to system, large amounts of wire wasted
2. Cross talk eliminated can save wire and time

Review: Ribbonized, Organized, Integrated wiring is a new concept here to simplify our wiring processes in airplanes.

I'm having serious problems with the works cited they are PDF files from a contact at Raytheon.
