Thin Red Line Projects

SPACE EXPLORATION – HUMAN HABITATION & CREW VEHICLES

Bigelow Aerospace inflatable habitat
Genesis spacecraft flight hardware

Thin Red Line developed and supplied 20 full-fidelity inflatable pressure shells of up to 320 cubic meter volume for Bigelow Aerospace. Thin Red Line designed, engineered and manufactured the pressure restraining hulls of Genesis 1 and 2 (launched 7/2006 and 6/2007 respectively), the first spacecraft on orbit successfully incorporating large volume, high-stress inflatable architecture.

Thin Red Line UHPV (Ultra-High Performance Vessel)
NASA Langley Research Center

Teamed with Paragon SDC, Thin Red Line performs verification and validation studies for its innovative inflatable UHPV technology. As concept development for the NASA Flagship RFI, “Inflatable Module Mission”, this Lockheed Martin image shows Thin Red Line UHPV-based habitat architecture docked to International Space Station Node 2.

Lunar Habitat architecture
NASA Johnson Space Center

Design and fabrication of a one-third scale habitation pressure module using Thin Red Line’s proprietary UHPV architecture. Virtually unprecedented, UHPV load paths are determinate—leading to unsurpassed predictability of structural performance and scalability. Mathematically verified as mass optimized architecture, UHPV currently offers higher specific strength than competing alternatives.

NASA Lunar Surface System Concept Studies
Boeing Lunar Surface Architecture team

As inflatable habitat specialist, Thin Red Line Aerospace supported expandable architecture concept development for the Boeing MFHE (Minimum Functionality Habitat Element) study.

ADVANCED INTEGRATED HYPERSONIC ENTRY SYSTEMS

Integrated Inflatable Ballute for Planetary Entry
NASA Ames Research Center

Teamed with CFD Research Corp., Thin Red Line is developing an integrated inflatable decelerator for planetary entry. Scalable to accommodate payloads of over 10 metric tons, the system includes thermal protection and load bearing attachment for guidance and control (G&C) hardware. Integrated fluid-structure thermal simulations are conducted with CFDRC's validated tools to provide insight into aerodynamics, material stress, and localized heating effects, and to verify and optimize design variables.

SPACECRAFT SHIELDING

Advanced Inflatable Radiation Shielding
NASA Langley Research Center

Study of integration methods and effectiveness of various deployable radiation shielding approaches in the context of Thin Red Line inflatable habitat architecture. The integrated, flexible-deployable architecture offers modular radiation shielding with significantly reduced mass and encumbrance.

MMOD (Micrometeoroid and Orbital Debris) Shield
Deployable MMOD shield test article for Bigelow Aerospace, for launch load vibration testing at NASA Jet Propulsion Laboratory. The ballistic shielding effect of the expandable structure is largely optimized by deploying substantial space between successive parallel shielding layers to allow conical dispersion of impact debris clouds.

Orbital Debris (MMOD), Multi-layer Insulation (MLI),
Integrated Shielding

Thin Red Line’s integrated deployable shielding design incorporates multifunctional material layers providing optimized spacecraft MMOD, thermal and radiation protection. Besides protection for habitation architecture Thin red Line’s design is particularly relevant to orbital propellant depots and cryogenic storage.

PRESSURE VESSELS, PROPELLANT TANKS, CRYOGENIC STORAGE

Lightweight Inflatable Cryogenic Tank
NASA Kennedy Space Center

Teamed with Technology Applications Inc., Thin Red Line’s inflatable UHPV technology is investigated as powerful alternative to cryogenic COPV’s. UHPV’s extreme simplicity permits incorporation of a much broader spectrum of corrosive content (LOX, LH2, LCH4, etc.) compatible liner materials. For propellant depots UHPV can be packaged for launch, filled in-situ, and repeatedly depleted to almost zero residual.

Helium Capture
NASA Kennedy Space Center

Teamed with Sierra Lobo, Thin Red Line led concept development for high pressure helium containment to volumes of 500 cubic meters using Thin Red Line’s proprietary UHPV (Ultra-High Performance Vessel) inflatable architecture technology. Thin Red Line’s design is the highest strength fabric containment structure ever contemplated and is applicable to an exceptionally large range of terrestrial and space exploration applications.

RENEWABLE ENERGY

Undersea compressed air energy storage (CAES)
Inflatable underwater containment facilitates highly efficient storage of offshore wind, tidal and wave power as compressed air (> 30 MJ/m3 at 700 m depth). Attached to the seabed, the inflated vessels would expel the depth-pressurized air to power turbines generating electricity during periods of high demand or intermittency of supply. Thin Red Line Aerospace is supporting Prof. Seamus Garvey’s visionary ICARES Project at University of Nottingham, UK, with design and fabrication of undersea vessels to 50 m3. Project efforts include concept development for volumes to 6000 m3.

OTHER PROJECTS

Airbag Impact Attenuation R&D
Thin Red Line’s UHPV technology facilitates the lowest mass and encumbrance airbag system of any competing design. UHPV performance predictability during a rapid compression event can be characterized and validated analytically for a broad range of impact attenuating applications without unduly complex and/or extensive testing. Thin Red Line’s innovative design permits attenuation scalability without reliance on burst disc calibration.

Rugged, collapsible solar concentration device
Office of Naval Research

Teamed with Infinia Corp. under an OSD contract, Thin Red Line Aerospace is applying its inflatable UHPV technology to solar concentrator architecture to support tactical energy production.
Inflatable Antenna R&D
Taking advantage of UHPV’s geometric determinism, Thin Red Line manages an in-house R&D program for design development of large aperture inflatable antenna systems.

Planetary Balloons / High Altitude Airship (HAA)
The exceptional mass efficiency of Thin Red Line’s proprietary inflatable technology extends the mission envelope of planetary and terrestrial high altitude systems by providing the lightweight structural elements needed to develop large surface area lifting bodies. Besides HAA technology for Earth atmosphere surveillance applications, Thin Red Line’s acid resistant and Montgolfière concepts respectively target NASA objectives Venus and Titan.

Human Protection
Thin Red Line has a long history of design, testing, and field application of critical use rescue, aviation, and tactical personal protection systems.

Advanced Materials R&D
Spacecraft life support gas barrier material testing

Thin Red Line’s work at the leading edge of fabric and film structure engineering demands commensurate intimacy with the latest advanced materials. The most recent fabrication technologies are exploited to generate a finely tuned symbiosis of material and structure.
