A Multi-Disciplined Approach

NAVSEA’s DefinitionTopside Design Incorporates Many Disciplines
-Safety Nets-Life Lines/Stanchions-RADHAZ-Pointing/Firing Cut Outs

Integrated Topside – Antenna Challenge!
• Performance (bandwidth, multiple simultaneous links, etc.)
• Topside weight (ship stability)
• Topside antenna blockage (“clutter”)
• Mutual interference (EMI)
• Signature (RCS, IR)
• Maintenance/Manning
• Total Operational Costs
• Increasing threat

First – Design Requirements
• Loading– Marine Environments
• Seaway Loading– Wave Slap/Green-Water
Loading, Sea Conditions, Ship Motion/Accelerations
• Salt Fog/Salt Spray, Corrosion– Vibration
• Shipboard Vibration• Blade Rate
– Shock• UNDEX – Direct Mounted
Equipment
• HM&E– Weight, Power and Cooling– Maintenance
• Life Cycle
• Material Selection
9
Second – Physical Integration
• Arrangements– Foot Print vs. Surface
Area
• Attachment Methods– Foundations vs.
Perimeter attachments– Internal Structural
supports
• Transitions
10
Third – Can we build/integrate it?
Requirements development and design MUST incorporate shipyard producibility aspects
– Environment– Production Capabilities– Tolerances– Craft Skill Level
11
Fourth – Unfamiliar/Uncomfortable
• The Risk – Input from areas we do not understand– Real/Perceived
$1
13
Everything
• Stove pipes limits success– Stove pipes produce great
products but integration piece is lacking
• Every Discipline must be actively involved in the designs– Equipment Manufacturers– System Integrators– Software Developers– Physical Integrator
15
Leave our comfort Zone
• Learn to communicate across disciplines– Understand each others pain– Have open and honest discussion concerning compromise
• Get involved early in sub-system designs– It easier to modify designs early in the process to support
integration
• Understand stove pipes will not work– Stove pipe organizations are not the problem – communication is
the problem– Need to learn to work across existing stovepipes
