Manufacturing and Engineering Services

Paragon has developed in-house world class engineering services to provide superior technical solutions to the problems our customers face in the most challenging of environments. Our specialization is the development, design, and manufacture of environmental life support and thermal control systems. The engineering services that we are expert in are listed below.

Aerospace Tubing

Paragon provides high-precision tube bending and specialized welding services, including orbital welding, and expert in bending and welding very thin-walled tubing. Providing a turn-key service from design, layout, manufacturing and testing, Paragon is AS9100-certified and is one of few companies familiar with and capable of complying with NASA human spaceflight requirements.

Environmental Control and Life Support System analysis and design

Paragon utilizes proprietary ECLSS models and a thorough knowledge of existing and next generation life support technologies to develop integrated system solutions for our customer’s most challenging life support needs. Recent life support system development activities include design of ECLSS solutions for flight tested prototype inflatable habitats, commercial crew transfer spacecraft, and terrestrial contaminated water diving suits.

Thermal Control analysis and design

Paragon uses sophisticated thermal modeling techniques and software to solve problems such as predicting vehicle performance at Mars surface operating conditions, passive and active control of hypersonic vehicles and satellite systems, and cabin thermal control for human and cargo transport in sea and in space. Paragon’s “complete vehicle” approach produces elegant, integrated, lightweight, and highly operable thermal control solutions.

Systems Engineering

Paragon is expert in systems engineering due to the simple fact that our core competencies of environmental and thermal control touch on all aspects of vehicle design and operation. Using a structured and value-added approach, Paragon provides systems engineering services including requirements analysis, synthesis and decomposition, functional and behavioral analysis, systems sensitivity and trades analysis, full vehicle schematics, and optimization of the complete vehicle – not just the subsystems.

Applied Research and Development

Paragon has proven performance in developing next generation environmental and thermal control components and subsystems that routinely exceed customer requirements. Paragon’s strong research and development program is both internally and externally funded, and it is focused on the development of innovative, cost-effective, and timely solutions for our customers.

Precision Manufacturing

Paragon’s precision manufacturing capabilities are core in our ability to provide space qualified or military grade products to our customers. Whether it’s fabricating a quick turn prototype for a spacecraft thermal control subsystem, or completing final build of a critical life sustaining environmental control sub-system, the manufacturing department’s role is central to the successful delivery of high quality products to a demanding marketplace.

It is manufacturing’s mission to support the needs of each customer, enabling Paragon to deliver on their commitment to provide superior environmental control systems, thermal control systems and sustainment solutions.

Paragon Space Development Corporation’s manufacturing department supports all of Paragon’s programs and provides low volume, quick turn mechanical solutions to a growing list of aerospace organizations. This work includes the creation of component prototypes, the completion of production hardware, and the development of low volume obsolescence solutions to our civilian and Government customer base. Our products have gone from below sea level to the vacuum of space and points in between.

Paragon has particular expertise in the manufacturing and production of space based mechanical components, and has recently expanded their offerings to include precision tube design & manufacture, as well as lower volume obsolescence support. Because of our expanding role within the aerospace community, we’ve just completed an expansion project that will increase usable manufacturing floor space by 3000 ft2, and includes new CNC assets such as mill, tube bending & lathe machines.

We use the latest in CMM technology to inspect both in-process and finished machine parts and assemblies. Our CNC machine handles stainless, titanium, aluminum, plastics and ceramics. We have developed orbital welding capability for aluminum, stainless, and titanium. Paragon maintains an ISO Class 7 level clean room for post processing and integration, primarily in support of our space products offerings.

Paragon provides high-precision tube bending and specialized welding services, including orbital welding, and expert in bending and welding very thin-walled tubing. Providing a turn-key service from design, layout, manufacturing and testing, Paragon is AS9100-certified and is one of few companies familiar with and capable of complying with NASA human spaceflight requirements. Paragon offers full CAD/CAM design capability, including design verification through, rapid prototyping to end item manufacture. Lower volume legacy support is offered to the obsolescence market through services such as build-to-print, reverse engineering and technical data package generation.

Paragon’s manufacturing staff has over 60 years’ experience in aerospace manufacturing and assembly. We work closely with our internal and external customers and use lean manufacturing techniques to ensure that all manufactured products will satisfy our customers’ needs.

Environmental Testing

Paragon has developed the only privately owned and operated facility for testing environmental and thermal control subsystems and systems rather than just components. Paragon’s ECLSS Human Rating Facility (EHF) is designed to test spacecraft and spacesuit systems and subsystems during nominal and off-nominal operational scenarios, measure human metabolic rates, aid in assessing integration issues, and more!

Paragon Space Development Corporation has created the only privately developed and owned Environmental Control and Life Support Systems (ECLSS) Human-rating Facility (EHF) (US Patent #7,441,473) for spacecraft system testing in a dynamic flight environment. This facility allows for simulating the very stressing dynamic changes in pressure, altitude and operating conditions experienced during human spaceflight, including suborbital and orbital flight profiles, as well as Martian and lunar environmental conditions. Simulating the dynamic response of changing mission phases is imperative to determine any complex interactions of pressure, thermal and gas constituent control that may manifest during flight. Testing of space suits, pressure suits and ECLS systems can also be performed for failure scenarios that are not able to be duplicated during flight testing. The facility allows for testing of ECLSS hardware before integration with the spacecraft, lowering ECLSS development cost and time, decreasing flight test time, and reducing program risk. The EHF also has the ability to perform metabolic testing on regular people, as most metabolic information, such as oxygen use, carbon dioxide production, and water vapor production is only available and used for people in peak physical condition, such as career astronauts.

The EHF is a 180 cubic foot stainless steel chamber with multiple flanges for incorporating hardware. The flanges are ConFlat flanges, which are a vacuum industry standard and can be adapted to a number of other types of fittings. There are 11-2.75", 2-4.5", 4-8", 3-12" and 1-16.5" flanges so multiple types and sizes of equipment can be used. Two ‘antechambers’ are currently attached to two of the larger flanges to simulate external environment pressure. These antechambers can control pressure throughout rapid profile changes to simulate external environment pressures during a sub-orbital or orbital spaceflight trajectory. Solid flanges between the main chamber and the antechambers are used to attach equipment that may release gas from any system that is being tested. Additionally, the EHF has multiple high-precision sensors to measure CO2, O2, temperature, humidity and pressure. The interior can be modified to seat anywhere from 1-4 people comfortably with audio and video communication. Data Acquisition is performed by National Instruments software and multiple channels of information can be recorded for analyzing test results.

Safety Quality and Mission Assurance

Paragon achieved AS9100 certification as a commitment to better serve our customers. Certification demonstrates the existence of an effective quality management system that is designed towards continuous improvement and exceeding customer expectations.
