The SkyDoc™ Aerostat System

 

We have operated in hurricane force winds over 90 MPH!

40 to 50 MPH winds are not a problem for the SkyDoc™ Aerostat when aloft. The unique design of the SkyDoc™ Aerostat creates added lift and stability as the wind increases.

 

The SkyDoc™ Aerostat is a system that can launch and retrieve payloads such as surveillance cameras, communications, and scientific equipment. Our clients are militaries worldwide, oil companies, police departments, Universities, and more.

Comparing the SkyDoc™ Aerostat with a Blimp Under the Same Conditions

The following charts compare a SkyDoc™ Aerostat that has been trimmed at -4 degrees of attack angle with no payload, and a blimp. Changes in the attack angle and payload will vary the height the SkyDoc™ Aerostat will settle at in wind conditions. Varying the attack angle from -4 to -8 degrees, changes in wind speed, and amount of payload can vary the angle of the tethered SkyDoc™ from 90 Degrees to 20 Degrees. Greatest stability with lift is generally found by trimming the aerostat to a -4 degrees attack angle.

Single-Ply SkyDoc™ Aerostat

*      Aerostat is made of Urethane.

*      Aerostat expands with temperature rise. Helium loss is 1 to 5 percent per week,
depending on temperature swings and aerostat pressure.

*      Net lift is at zero wind speed. Maximum lift is at 90 mph wind speed. Aerostat's smaller than Model #15 are not stable in high winds.

*      Net lift is at Sea Level. Subtract 15 per cent at 5000 feet.

Note: SkyDoc™ aerostat Model numbers are stated as Filled Diameter and Filled Height. SkyDoc™ filled aerostat sizes are stated with normal pressure. Welder’s grade helium is required. Tether weight must be added to payload weight to calculate total lift.

Additional SkyDoc™ Aerostat Information

*       This Helium aerostat platform is designed to meet specific criterion that has been requested by many operators of aerial specialized equipment. This aerostat has been developed through intense research of fabrics, materials and designs that are tuned to the needs of these users. This aerostat is designed with state of the art components that offer optimum performance and reliability.

*       The single-ply aerostat is made from a single-ply material consisting of urethane.

*       The two-Ply aerostat is designed for adverse environmental conditions.

*       The balloon apex is capable of supporting a variety of payloads attached with a three point configured platform. Special Mounting Patches for the belly of the aerostat are available.

*       A large area can be painted with your logo or sign on the 2-ply aerostat. Unlike a blimp, the message is seen 340+ degrees from the ground.

*       The aerostat is stabilized better than a blimp and is designed for ease of assembly and set up.

*       The single-ply aerostat will expand and contract with the pressure. Average loss per week is 1-5 percent. If it is punctured, it can easily be repaired. Temperature variations will expand and contract the balloon.

*       The 2-ply aerostat has an optional pressure release valve that will open with increased temperature.

*       The aerostat design allows for additional lift with increased wind speed.

Aerostat Color Options

*      Single-Ply SkyDoc™ Aerostats come in standard colors of white, red, blue, and yellow.

*      Top of aerostat may not be a different color than the bottom of the aerostat.

*      2-Ply Aerostats may be almost any color.

Note: Logo's are not recommended for Single Ply Aerostats.

Patented Components Designed for Hurricane Force Winds

Rapid Deployment

Air Transportable

High reserve buoyancy

DEPLOYMENT
The SkyDoc™ 22 foot single ply aerostat requires up to six (291 cubic feet) helium bottles and 22,600 pound capacity line pull Winch.

TETHER LINE
A SkyDoc™ 22 foot single ply aerostat requires a tether line that will withstand over 2,600 pound pull. This tether line must be capable of not stretching even under these high lifting situations. We provide the best tether line in the world for this unique aerostat. Standard tether, tether with conductors and optical fibers woven in the tether are available.

RECOVERY
Recovery is not normally required until the operation has been completed. Recovery is quick and easy. The compacted aerostat is then ready to re-pack into the container for storage until the next deployment.

TRANSPORTATION & STORAGE
SkyDoc™ is easily transported by truck, vessel or aircraft.

SPECIAL NOTES

*      The special design of the SkyDoc™ aerostat allows for increased lift with increased winds. Thereby the payload stays aloft in hurricane force winds.

*      No special enclosure is required for the payload during heavy winds once it has been launched, the system will operate until the task is completed. Because of its special patented components design, the amount of helium required is kept to a minimum.

*      Due to the bow of the tether line in high flying configurations, a maximum of 5,000 feet of tether line is recommended.

*      Single-Ply Aerostat is not recommended in areas that may have flying ice particles.
