The Role of Aviation in Urban Warfare Capstone Project Report 18 December 2009 Team Sikorsky (#7): Michael Bovan, Bryan Driskell, Michael Ingram, Jay Stewart, Damian Watson http://mason.gmu.edu/~jstewarc syst-798@googlegroups.com
Agenda • Project Introduction • Requirements & Elicitation • System Architecture • System Analysis • Business Plan & Technology Assessment • Conclusion & Road Ahead
Background • 80% of worldwide population in urban environments by 2030 • Unified population of terrorists / enemy combatants and civilians alike • Example: 2008 Mumbai terrorist attacks on Taj Mahal Hotel • Urban Environment Vertical Takeoff & Landing (VTOL) Missions: • Search & Rescue (SAR) • Attack & Target Designation • Troop Transport • Reconnaissance • Logistical Resupply
Problem Statement & Objective • Problem Statement • Increasingly Urban Battlefield • Unique Challenges for Aviation Assets • Red vs. Blue Warfare Model is Ineffective • Unknown / Undefined Roles • Project Objective • Analyze the role of VTOL aviation for future military missions in urban environments. • Evaluate current aviation platforms • Identify technology gaps • Develop mission and/or system requirements and conduct trade-off analysis
Deliverables, Assumptions, & Scope • Deliverables • Quantitative Analysis • System Requirements • System Architecture • Assumptions & Scope • Focus on military operations and military vehicles • Focus on VTOL vehicles • Focus on SAR operations within the urban canyon (UC) • Stakeholders
Supporting Documents (Developed) • Proposal & Problem Statement • Operational Concepts Definition • Objectives Hierarchy Analysis • Stakeholder Elicitation Plan • Requirements Elicitation Plan • System Requirements Traceability Matrix • System Requirements Specification • System Analysis & Scorecard • Physical Architecture • Business Plan & Technology Assessment
Project Schedule • Networked Schedule • Shows Critical Path • Critical Path - Stakeholder Elicitation and Functional Architecture • Gantt Chart • Start and Finish of Tasks • Shows Progress on Tasks
Agenda • Project Introduction • Requirements & Elicitation • System Architecture • System Analysis • Business Plan & Technology Assessment • Conclusion & Road Ahead 8
Requirements Elicitation - General Approach • Understand the stakeholders and ‘capture’ their requirements Meet with Prime Stakeholders Weekly Use Conversational Methods (Interviews, Focus Groups) • Analyzing stakeholder selections Defined High Level System Attributes Use interviews and an Attribute Ranking System Repeat process for lower level system attributes • Communicating stakeholder ideas Share elicitation choices between stakeholders Reach agreement on top choices • Agreeing on selections/requirements Negotiate with stakeholders about requirements Ensure Traceability between requirements and system attributes
Requirements Elicitation (Cont) Requirements For the VTOL Project, Requirements Elicitation was accomplished primarily through: • Weekly Meetings with Prime Stakeholder • Use of Current Event Discussions • Brain Storming Sessions • Attribute Ranking Elicitation • Scenario Discussions • Use Case /Activity Diagram Development • Requirements Document Reviews and Negotiations
Requirements Management Requirements Damian’s Comment Revised Requirement Action Taken Requirement Type # Original Requirement More • MS Excel 2003 • 200+ Requirements • Easy to Set up, Difficult to Manage • Cumbersome Traceability • Not easily Linked to other Architecture Modules
Requirements in Enterprise Architect Requirements • Improved “Nested” Structure • Configuration Management • Enhanced Requirements Traceability • Linkable to other Module Elements • Input • Operational Concept • External Interface • Functional • Technology • System Wide • Output
Agenda • Project Introduction • Requirements & Elicitation • System Architecture • System Analysis • Business Plan & Technology Assessment • Conclusion & Road Ahead
System Architecture Overview • Referenced Department of Defense Architecture Framework (DoDAF) v1.5 • Used non-DoDAF diagram to model Physical Architecture • Focus on applicable Systems and Services Views (SV-1 /4) • Diagrams developed using Unified Modeling Language (UML) • Tool: Enterprise Architect (EA) v7.1
SV-4 Example (Use Case) (Activity Diagram)

Analysis [1] • Data: Market Research & Sponsor Input • Scenario Development via Use Cases
Agenda • Project Introduction • Requirements & Elicitation • System Architecture • System Analysis • Business Plan & Technology Assessment • Conclusion & Road Ahead
Business Plan • Use • Investment • Partnerships • S-curve • Marketability • Consumer Use – Point-to-Point travel • Alleviate City street congestion • Policy & Law • Protect Noise Pollution • Safety
Technology Assessment [1] In Function to Form Mapping, certain functionality depends on “Critical Technologies”
Technology Assessment [2] • Used Morphological Box to generate solutions for each critical technology • Assessed feasibility and generated design combinations 28
Conclusions & Road Ahead • No one vehicle currently suitable for SAR mission • VTOL Maneuverability Technology and Safety limit SAR Mission Effectiveness • Communications Technology can support SAR Missions within the UC • Identified capability gaps • Conduct Analysis of Alternatives on Future Technologies • Develop Design Solutions
