Advanced Insulation Techniques for Cryogenic Tanks
45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009[Abstract] The ability to store large amounts of cryogenic fluids for long durations has a profound affect on the success of many future space programs using propellant, reactant, and life-support cryogens. These missions will require on-orbit systems capable of long-term storage of cryogens for applications such as: space transportation, orbit ...

Advanced cryogenic propellant tank development status
28th Joint Propulsion Conference and Exhibit, 1992The design and development of cryogenic propellant tanks with reduced weight and production costs is described with reference to applications for the National Launch System. The development program focused on the use of an aluminum-lithium alloy to demonstrate the production capability, manufacturability, and strength inherent in the novel material ...

Tenacious Composite Foams as Cryogenic Tank Insulation
46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005Reinforcing polymer foams with short aramid fibers has the potential to greatly improve the reliability of the thermal protection systems applied to cryogenic propellant tanks. The critical failure mode is peeling of the foam along the bondline with the tank.

Concentric tubular support design for cryogenic tanks
Cryogenics, 1993One of the critical factors in the design of a cryogenic tank is the method of suspending the inner vessel within the outer vessel. A thermally inferior suspension system can nullify the effect of using high performance thermal insulation. The authors describe a new design of support system in which the central suspension rod is under tensile stress ...

Phase Change in Cryogenic Upper Stage Tanks
50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2014Evaporation and condensation commonly occurs in cryogenic upper stage tanks during varying flight conditions, both under accelerated conditions (boost phases) as well as in ballistic flight phases. Generally the liquids in the tanks (LH2 and LOX) are in a subcooled state after pressurization on ground.

Health monitoring of reusable composite cryogenic tanks
36th Structures, Structural Dynamics and Materials Conference, 1995Martin Marietta Manned Space Systems is developing methodologies to automatically and efficiently determine the health of reusable composite cryogenic tanks. The integrated health management (HM) system will consist of sensors, instrumentation, and automated analysis tools which will certify and recertify reusable cryogenic tanks in a timely and ...

Novel orbital disconnect support for cryogenic tanks
Cryogenics, 1994Abstract The orbital cryogenic lifetime of Dewars can be significantly increased if the supports which fix the cryogen tank to the Dewar vacuum vessel are disconnected on orbit under 0 g conditions. In a study performed under an Estec contract, 16 different concepts of purely passive and of active cryogen tank supports were assessed.

An enhanced thermal model for cryogenic tanks
2008 Second International Conference on Thermal Issues in Emerging Technologies, 2008This work studies heat transfer in a cryogenic tank, in order to estimate the heat infiltration rate as well as the required thermal insulation thickness needed to fulfill the boil off ratio. It addresses some general recommendation about thermal insulation thickness.

Thermodynamic model of cryogenic fuel tank processes
Space engineering and technology, 2020A new procedure is created for the calculation of heat and mass transfer processes in a cryogenic rocket tank. This simplified method is based on the assumption about homogeneity of temperature in liquid and vapor phase of a fuel component. This assumption made this model useful for such regime as refueling, self-pressurization, pressurization during ...
