    • Lightweight Aerostat System 19 November 2010
    • LAS Briefing Outline LAS Background LAS Missions LAS System Description System Development Summary / Questions
    • Typical Aerostat Missions / Capabilities Local Area Surveillance Small / Remote Military Locations Border Surveillance / Protection Other Homeland Security (High Value Locations / VIP Events) Communications Relay Coverage To Convoys And Dispersed Units Coverage To Low Altitude UAVs and to UGVs / USVs Post Disaster Communications Coverage / Translation Node Persistent Intelligence Coverage SIGINT / COMINT Tower Line Of Sight (LOS) Is Limited Aerostats Provides LOS Comparable To Aircraft Or UAVS But Persistence Of Towers Persistent Surveillance And Communications Relay Over Large Coverage Areas Even A Large Tower Is Limited To About 10 Miles An Aerostat At 500 Feet Has A LOS Of 24 Miles, And Can Operate At Much Higher Altitudes Small Aerostat Large Tower
    • Traditional Aerostat Limitations 17 Meter Long Aerostat Traditional “Blimp” Aerostats Driven Into Ground by Winds, Must Be Large, With 200 -300 Lb Lift, To Withstand Wind These Large “Tactical” Aerostats Are Clumsy To Operate and Require Large Crews Big Ground Equipment, Not Very Mobile / Transportable Not Suitable For Small Fixed Locations or Mobile Operations Expensive, Limiting Number That Can Be Deployed SOLUTION: A Lifting Aerostat Uses Aerodynamic Lift to Remain Aloft in Wind – Even For Small Systems / Payloads Downsize the Ground System to the Payload 21 Meter Long Aerostat
    • Lifting Aerostat Versus Traditional Blimp With No Lift Surfaces, Wind Pushes Traditional Tethered Blimps Back and Down Blimp Based Aerostat Systems Must Be Very Large To Cope With Wind Drag Requires Large Ground Handling Equipment and Vastly Increases Operating Cost They Cannot Capitalize On Modern Miniature Electronic Payloads Lifting Aerostat Are Pushed Up By Wind, Counteracting Wind Drag Even Small Units Can Operate In High Winds LAS With Lifting Aerostat Can Be Sized To Available Modern Lightweight Payloads Wind Blimp Lifting Aerostat
    • Lightweight Aerostat System HMMWV Compatible Carrier Trailer Helikite Lifting Aerostat Helirest Protective Mount Gyro –Stabilized Camera Payloads Networked Communications Payloads Acoustic Gunfire Detectors / Other Payloads
    • LAS Surveillance Mission Persistent Video / IR Surveillance to 10km (Sensor Limited) Suitable For Small Dispersed Base Camps Small Logistics Footprint Rapidly Relocated Operated by Only Two People Towers Are Simple And Have Good LOS – Why Aerostats For Local Surveillance? Altitude Minimizes “Shadow Effect” Of Obstacles Providing Hide Space For Enemy Compare Shadow Effect Of A Two Story Building 500 Feet From A 100 Foot Tower And A LAS At 500 Feet LAS Can Fly At 1000+ Feet To Reduce Hide Space Even Further 180 Foot “Hide Zone ” 25 Foot “Hide Zone”
    • LAS Communication Coverage Communications Relay to 100km Few Units Give Large Area Coverage Greater Range by Relaying From One LAS to Another. No Convoys or Anti-IED Patrols Need Be “Off-The-Net” Continuous Communications Even in Cluttered Urban Areas
    • Homeland Security Support LAS Can Cover Large Disaster Areas One-To-One Communication Relay Network In The Sky For Multiple Users Translation Bridge For Enhanced Multi-agency Interoperability Mobile and Air Transportable To Get To Disaster Quickly LAS To LAS Relay To Regional / State Command Center LAS Coverage Example (North Carolina Hurricane Response) 1500 Altitude 1000 Altitude 750 Altitude
    • LAS Subsystems Helikite Performance Safety / Survivability Helirest Protection / Storage For Helikite Carrier Military Off Road Trailer Civilian Trailer Typical Payloads Electro-Optic / IR Sensors Communications Logistics Two Person Operation Minimum Helium and Fuel Standard Spares
    • Helikite Lifting Aerostat Patented Allsopp Helikite, Produced in England, is a “Lifting Aerostat” Combining Helium and Aerodynamic Lift Flies On Buoyant Lift in Zero Wind, Aerodynamic Lift in Wind Due to Aerodynamic Surfaces Helikites Will Fly At 45 o Even In High Wind (Lift To Drag = 1) Helikite Allows Lightweight Aerostat System to be Smaller and Still Operate in Real World Weather Conditions System Can Be Sized to Available Modern Lightweight Electronic Payloads Safe and Survivable: Difficult to see, No IR or Radar Signatures, Helium Will Not Burn, Due to Low Pressure Only Slowly Deflates Even if Hit By Multiple Bullets Sea Level - 120 F
    • Helikite Docking System (Helirest) Air Inflated Helirest Protects The Helikite During Inflation / Deflation And Ground Storage Prevents Helikite Movement In Wind During Inflation / Deflation Helikite Shape And Short Tether Attachment Allows Bringing Helikite Down Close To Ground, For Safe Tiedown And Restrain Other Aerostats With Multiple Attachment Lines Cannot Utilize Helirest, Must Remain Tens Of Feet Above Ground In Turbulent Wind Zone Helirest Allows Eliminating Clumsy Pivoting Mooring System, Reducing System Size And Complexity A Key To Operation With Only Two People, With All Work Done Safely Inside Helirest 1 Helikite Helium Fill Nozzle 2 Tiedown Lines 3 Deflation Electronics 4 Helirest 3 2 1 2 4
        • Helikite With Helirest
    • Military Off Road Carrier “ Turn Key” System Carries All Equipment Aboard Trailer HMMWV Compatible Trailer Electric Winch Diesel Generator (JP-8 Fuel) Elevates Payloads to 4000 Feet Quick Inflation Helium Manifold Helium Tanks Standard NSN Item Operable by 2 Persons C-130 Roll On – Roll Off Capable
    • Commercial Trailer Version Supports DOE Nuclear Security Mission Carries Camera and Communication Relay Payloads Altitude to 1000 Feet in 20 Minutes From Stopping Launches From Trailer Top Launch Method Has Been Adapted To Military Versions Delivered April 2006 Sandia National Lab Version Photo By Sandia Lab
    • Typical LAS Payloads Communications Payloads Are Mounted Directly Under The Helikite Horizontal Keel Simple Strap Mounting Is Easily Adapted To New Payloads Payloads Or Battery Packs Can Be Changed In Under Two Minutes Camera (EO / IR) Payloads Are Mounted Below The Helikite Keel Cloth On A CUV Designed Support Mounting Avoids View Blockage From Keel Cloth Payloads Can Be Changed In Under Two Minutes
    • Minimum Logistics Burden Single Trailer Carries Everything For Deployment Two Person Operation Cross-trained Mechanical / Electrical Techs Operate System Including Payloads Minimum Helium Requirements Standard NSN 216 Cu. Ft. Tanks, No Special Helium Trailer Standard 35M3 Load Is 7 Tanks, For One Inflation And 4 Weeks “Top-off” Helium Can Carry Two Inflations, Or Enough Helium For One Inflation And 6 Months “Top-off” 6 Tanks For Reinflation Is Less Than One HMMWV Trailer Or Pallet Load Low Fuel Consumption Less Than 15 Gallons Per Month For The System Automotive Spares (Tires, Brakes, Lights) In Military Supply System 35M3 Carrier Showing Tanks and Winch
    • System Design Options Parameter Primary Effect Other Effects / Comments Payload Weight Aerostat Size Tank Number, Carrier Size To Support Helikite, Tether Strength, Winch Size Operating Height Weight of Tether Affects Aerostat Size Payload Power And Endurance Standard Or Power Tether Tether Weight, Winch Design (Slip Rings) Payload Type Mounting Provisions Operating Conditions Helikite Size Affected By Ground Elevation, Temperature Mobility Of System Carrier Design Safety / Regulatory Features Weight of Devices Lights, Deflation Devices
    • Summary - LAS Attributes Mobile “Lifting” Aerostat for Security, Communication Relay and Other Missions Low Cost Solution to Persistent Wide Area Surveillance Coverage Good Adverse Weather Capability Remains Aloft For a Week or More Highly Mobile, Air Transportable by C-130 Two Person Crew All Consumables and Most Spares in Supply System Adaptable To Varied Payloads Adaptable To Homeland Security, Military and Naval Operations Deliverable in 6 Months From Start Typical Cost $350K to $500K Plus Payload
