What is ARES?
AACUS
ARES
User Defined Payload Modules• Compact Landing Zone – Half of Typical Helo
• Higher Speed Than Helos • Embedded with Infantry• Closed Rotor for Safety• Field-Changeable Payload
Autonomous Control
KMAX• Pioneering
Unmanned Cargo• Gets Trucks Off
IED Roads
• Autonomous Aerial Cargo Utility System
Transformer Phases I and II
• Modular Concept• Roadable VTOL
Modular Cargo UAS
VTOL ISR
CASEVAC
Separable UAV
Aerial Reconfigurable Embedded System
Multi-Mission VTOL Transport UAS
• Highly Autonomous VTOL, Navigation, Obstacle Avoidance, Autoland
• Fly-By-Wire Flight Controls with Redundancy • Intuitive Human / Machine Controls for Non-Aviator Operators

ARES Operational Vehicle Vision• Next Generation Modular VTOL Unmanned System
• Field-Changeable Payloads – Multi-Mission with Single Type of Lifter• Compact Landing Zone – Half of Typical Helo• Tilting Ducted Fans - Closed Rotor for Safety and Speed• Highly Autonomous – Usable by Non-Aviator Troops in the Field
Deliver Light Vehicles • SOF Support
Unmanned Cargo• Food, Fuel,
Water, Ammo• Palletized loads
CASEVC• Dedicated
Medical Lift• Humanitarian Aid• Disaster Relief
Small Unit Transport / Utility• Armed Scout• SOF Infil/Exfil
VTOL ISR• Purpose Built Sensor
Pod and BLOS Comms• Longer Loiter w/ Added
Fuel

What is the Role for ARES?Point to Point Delivery of Right Sized Loads for Users
=
=
vs. Mass Transportation of Bulk
• Door to Door Delivery at Point of Need• Multiple Units Operating Simultaneously• Each Modular Vehicle is Lower Cost than Heavy Lifter• Autonomous Delivery – Not Tied to GCS
• Emphasizes Design for Max Lift Weight• Speed Secondary • Needed for Outsize Cargo or Heavy Items• Larger and more Expensive Lifter

ARES –Modular UAS Concept Integrates Existing Tech
Payload Pods Sized for User Needs• Low Cost – Interchangeable Pods• Payload Protected from Wind and Weather
Closed Rotor for Small Takeoff and Landing Area• Improved Safety for Ground
Operations• Half the Landing Area of
Conventional Helo• Folding Outer Wing Panels
Twin OTS Turboshaft Engines• Reliability and Redundancy• Geared to Cross Drive Shaft• Scalable Systems
Fly By Wire Controls • Triplex for Safety and
Redundancy • Sensors for Automated
Navigation and Landing• iPad style mission
programming
Twin Tilting Ducted Fans• Tailored Duct Shape
for Rapid Transition to/from VTOL
• Mono-Cyclic plus Aero Controls
• Scalable
6
Demonstration Program• Build and Fly Demonstrator in 2015. Show Design is Traceable to
the Field Vehicle– Full Scale Flight Module– Maximum Use of COTS Hardware – COTS Engines, OTS Actuators,
Gears, Flight Control Hardware, etc for Low Cost– Ground Control Station for Remote Pilot UAV Demo
• Demonstrate Core Capabilities of Modular VTOL UAV Flight– Measure Thrust on Ground Test Stand– Demonstrate VTOL and Hover– Demonstrate Transition to Forward Flight and Back to Hover– Demonstrate Basic Handling and Performance in Flight– Demo Modular Payload Delivery and Separable Flight

Summary• Next Generation of VTOL UAS
– ARES = Aerial Reconfigurable Embedded System– Modular VTOL Payload Delivery – Cargo, ISR, other– Designed for Operation by Non-Aviators (Infantry)
• Working toward Demonstrator Build and Test in 2015– Fast Paced DARPA Demonstration Program– Hardware Being Built Now for Demonstrator– Demonstrator will be Remote Piloted
• Working Transition to Operational System– Talking to USMC, US Army, SOCOM, other users– Gathering User Input for Operational Requirements– Incorporate Technologies for Autonomy
