Since opening its doors in the early 1970's, EDO Fiber Science has been designing and producing composite tanks and vessels for water, waste, fuel, and various gasses, for a multitude of service pressure and temperature regimes. EDO Fiber Science has built cylindrical tanks, box tanks, and custom tanks to conform to tight installations. Tanks have been produced for use on commercial and commuter airliners, military helicopters, trucks and busses, and fighter jets. A variety of custom high-pressure tanks have also been designed produced for research and development programs.

AIRCRAFT FUEL TANKS
EDO Fiber Science has designed and manufactured external aircraft fuel tanks for over twenty years. Few companies, if any, have this level of experience, especially when combined with the diverse customer and aircraft mix EDO Fiber Science has served. From rotary wing to subsonic and even supersonic fixed wing aircraft, EDO Fiber Science offers a depth of unparalleled expertise. EDO has produced auxiliary fuel tanks used on H-3, H-60, Chinook helicopters, and the CF-18.

Composite Fuel Tank Benefits: Composite external fuel tanks are lighter in weight and offer much improved resistance to crash damage, small arms fire, cannon shells, fire and corrosion.Composite tanks can also be jettisoned for aerial combat or in other emergencies. They can enable mission profiles and capabilities not possible without the operating range extension afforded by the use of external tanks.

Typical Design Challenges: Materials for fuel tanks and liners, must, in many cases, be leak proof, explosion proof, fire proof, and resistant to ozone and ultraviolet light. They operate under positive pressure, and must be able to survive intense external impacts and tough operating environments. External aircraft fuels tanks, and their mounting systems, must meet stringent requirements for g-force (crash impact) loading, high and low temperatures, and service pressure cycles. Both require numerous secondary penetrations for installation of quantity sensors, probes, valves, inlets, outlets, and other hardware.

AIRCRAFT WATER AND WASTE TANKS -
Pioneers in Aircraft Composite Tank Technology
EDO Fiber Science has been a leading producer of potable water and waste tanks for commercial airliners since 1967. Many of the commercial aircraft in use today use EDO potable water tanks for their fresh drinking water. Each tank meets the challenge of difficult aircraft operating environments, from withstanding high "g" loads to extreme operating temperatures to emergency vacuum pressures.

Water and waste holding tanks are available in a variety of standard and custom shapes and sizes for commercial and military use. Because of EDO's extensive capabilities in liner forming and filament winding, tanks can be configured for the complex shapes required for available aircraft spaces while being economically produced. EDO Fiber Science provides the design and integration of critical tank components like quantity sensors, rinse nozzles, inlets, outlets, and filters.

Benefits of Composite Water and Waste Tanks: Composite water and waste holding tanks are lighter in weight and offer much improved resistance to corrosion. Composite tanks can also be conformal inside an aircraft to make optimum use of the space available.

Typical Design Challenges: Materials for water tanks must be FDA approved, for use in potable (drinking) water systems. Waste tanks are used in Boeing's vacuum pressure-driven Advanced Technology Lavatory System (ATLS) and must survive intense internal impacts, and caustic operating environments. Both types of tanks, and their mounting systems, must meet stringent requirements for g-force (crash impact) loading, high and low temperatures, and service pressure cycles. Both require numerous secondary penetrations for installation of quantity sensors, rinse nozzles, filters, heaters, inlets, outlets, and other hardware.

FILTER CANISTERS AND SYSTEMS

All vacuum waste tanks produced by EDO Fiber Science contain special air/water separators that work in conjunction with the vacuum system in the aircraft. These filters allow the vacuum source to draw waste from each lavatory to the EDO-supplied composite holding tanks, without allowing waste material past the tank and into the vacuum system.

AIRCRAFT TANK REPAIRS AND AOG SERVICE
As part of its total product support commitment to its business with Boeing, EDO Fiber Science provides repair services for water and waste tanks produced by EDO Fiber Science and most other suppliers. EDO Fiber Science is proud of its rapid turn-around on tank repairs and offers limited warranty coverage wherever possible.

EDO Fiber Science is FAA and European JAA certified to fully overhaul and repair most composite tanks, even if produced by another manufacturer. Around the clock AOG support is available, along with in-stock spares and parts when required.

EDO Fiber Science provides the best water and waste holding tanks, spare waste ducts (L-1011) and "24/7" support to every major air carrier in the world.

PRESSURE VESSELS
EDO Fiber Science has been designing and fabricating composite pressure vessels for specialty applications since the company's inception. In that time, both low-pressure air storage reservoirs and very high-pressure hydrogen fuel cells have flowed from the Salt Lake City plant. Most all are built on the "fly-away mandrel" approach to lined tanks and composite filament winding, in which EDO Fiber Science is a true industry pioneer.

Benefits of Composite Vessels: Most pressure vessel applictions are extremely weight sensitive and are, therefore, ideal applications of composites. They are typically used to store or contain an important or hazardous gas or liquid aboard some sort of transport vehicle.

 

Typical Design Challenges: As with piping used to transport liquids or gases, liners and composite pressure vessels must be compatible with the stored medium and offer leak-proof service for the long term. Service temperature and pressure (including negative pressure for a vacuum service tank) normally drive the design of any vessel of this type.

 

MARINE HOLDING TANKS
EDO Fiber Science has produced thousands of tanks for storage of liquids such as potable water, gray water, wastewater, diesel fuel, and jet fuel.

Tanks such as this are made using filament winding, hand lay-up, or other specialized processes, using glass and carbon fiber, and various resin systems.
