Lightweight Aerostat System (LAS)

Homeland Security Applications

An Improved Persistent Capability For Communications Relay

And Port / Border Security

More Mobile and Air Transportable

Minimum Manpower

Lower Acquisition and Support Cost

Large Coverage Area

Long Mission Duration

Versatile Payloads

http://www.carolinaunmanned.com/


LAS Overcomes Traditional

Aerostat Limitations

17 Meter Long Aerostat

SOLUTION: A Lifting Aerostat

Uses Aerodynamic Lift to Remain Aloft in Wind

Even Small Units Operate in High Wind

Smaller Aerostat Allows Smaller Ground System

Entire System Fits In Single HMMWV Trailer Or Truck

TCOM 17 Meter Long Aerostat

Traditional “Blimp” Aerostats Must Be Large To Not Be Driven Into Ground By Wind

Large Aerostats Are Clumsy To Operate and Require Large Crews

Big Ground Equipment, Not Mobile / Transportable

Not Suitable For Small Bases or Mobile Operations

Expensive, Limiting Number That Can Be Deployed



Lightweight Aerostat System

Subsystems

Helikite - “Lifting Aerostat” Combines Helium and

Aerodynamic Lift, Flies Even In High Wind

Helikite Allows LAS to be Small and Still Operate

in Real World Weather Conditions

Helirest - Air Inflated Helirest Protects Helikite

During Inflation / Deflation And Ground Storage

Prevents Helikite Movement During Inflation /

Deflation

Reduces System Size And Complexity

Carrier - “Turn Key” System Carries All

Equipment Aboard Single HMMWV Compatible

Trailer

Typical Payloads - Electro-Optic / IR Sensors,

Communications, Radar Payloads

Logistics - Single Trailer Carries Everything For

Deployment

Two Person Operation

Minimum Helium Requirements, Low Fuel

Consumption



Communications and Surveillance

Mission Performance

Provides Security EO / IR Camera Coverage Over A 10

Nm Circle For Border Or Port Surveillance

Altitude Minimizes “Shadow Effect” Of Obstacles

Hiding Smugglers / Terrorists from Surveillance Towers

LAS At 1000+ Ft Reduces Blind Spots Even More

Mission Duration Is Weeks At A Time, Far Exceeding

That Of Aircraft or Unmanned Aerial Systems

Two Person Crew Operates LAS And Sensors, Far

Fewer Than Aircraft Or UAS

Communications Relay to 50 Miles Or More

Few Units Give Large Area Coverage

Greater Range by LAS To LAS Relay

Local Agencies and State Command Center Connection

Payloads Available For:

One-To-One Communication Relay

Network-In-The-Sky Router For Multiple Users

“Translation Bridge” For Agency Interoperability

Tower 180 Foot “Hide Zone”

LAS 25 Foot “Hide Zone”

Compare Shadow Effect Of 2 Story Building (Or

Container Stack) 500Ft From A 100Ft Tower And

From A LAS At 500Ft

LAS Coverage Example (North Carolina Post-Hurricane Communication Coverage At 1500 Ft Altitude)



Summary

Mobile “Lifting” Aerostat for Communication Relay, Border / Port Security, and Other Missions

Low Cost Solution to Persistent Wide Area Border, Outdoor Event and Port Surveillance Coverage

Good Adverse Weather Capability

Remains Aloft For a Week or More

Road And Off-Road Mobile, Air Transportable by National Guard C-130

Two Person Crew

Minimum Logistics and Cost Burden, With All Consumables and Spares Readily Available

gauge carbon fiber panels.

• Weight savings: Direct and indirect weight savings with areal weights of 140

gsm and 190 gsm requiring less paint surfacer weight as well.

• Surface Finish: Improved surface finish over heavier expanded metal foil

solutions

• Manufacturing: Improved throughput by reducing surfacing and “metallization”

joining steps required with expanded metal foils.

• EMI Shielding: Enables composites to approach shielding levels of aluminum

skin

• Secondary Properties: Equivalent or superior to expanded metal foil in tests

including: corrosion, wear resistance, paint adhesion, solvent resistance, UV

Resistance, thermal cycling and mechanical fatigue.

• ALOFT glider with algorithm for

autonomous location and centering of

thermals

• PhD research of Dr. Dan Edwards

(Advisor: Dr. Silverberg)

Placed 3rd overall in 2008

Montague X-Country

Challenge, beating several

world-class RC glider pilots

Modeling for Real-Time Flight Simulation

• Pilots are increasingly being trained

in simulators

• Current sims are excellent for normal

flight conditions, but not for stall and

post-stall

• Recent high-profile airliner accidents

provide strong impetus for flight sims

to be reliable for stall recovery

training

• Stall aero/flight models for real-time

calculation being developed at NC

State under NASA Langley funding

• PhD research of Ryan Paul (Advisor:

Dr. Gopalarathnam)

• Potential for training UAV pilots in off-

normal flight conditions and in

turbulence

Simulation of

a stall/spin

maneuver.
