ATA Engineering has developed a lightweight and compact insulating barrier for expeditionary shelters. Based on a tensioned cellular fabric design concept, the barrier is intended to reduce electrical power consumption and packed size/weight of operational equipment by improving insulation qualities of softwall shelters. ATA is an engineering services company that provides innovative simulation and testing solutions to our customers in the defense, aerospace, and other mechanical design industries. The company leveraged this expertise in developing a barrier design for the Marine Corps’ Expeditionary Shelter System (ESS) (Medium), sold by HDT Global as the Base-X Model 305. ATA’s insulating barrier replaces both the existing interior liner and radiant barrier used in the ESS (Medium), greatly reducing the logistical footprint for the warfighter while improving insulative performance.
ATA Engineering’s computational analysis methods enable prediction of post-damage kinematic operation of critical shipboard mechanisms – specifically, whether submarine hatches, scuttles, and watertight doors will still operate after experiencing shock damage. ATA is an employee-owned engineering services company providing solutions in the design, analysis, and testing of complex mechanical products. We developed the technology to aid design of future submarines (e.g., OHIO Replacement Class) and qualification of equipment for existing ships by reducing the reliance on costly underwater explosion (UNDEX) testing. ATA’s approach leverages a commercially available finite element analysis (FEA) tool, Abaqus, and utilizes machine learning techniques for efficiently evaluating a large number of possible damage permutations. Current efforts involve validation through correlation with laboratory experiments. ATA seeks opportunities to support our customers’ shock qualification efforts.
ATA Engineering, Inc. (ATA) has developed a computational toolset for simulating complex thermo-mechanical responses of woven carbon-carbon (C/C) composite materials. The toolset, COMPAS(TM), is fully integrated within the ABAQUS finite element analysis environment to provide a novel capability for assessing the design of C/C thermal protection system (TPS) components used on spacecraft, reentry systems, and hypersonic vehicles. From partial information about constituent materials and limited mechanical test data, COMPAS extracts material model parameters (e.g., stiffness, strength) along with associated statistical distributions. As ATA completes comprehensive validation of the toolset’s predictive accuracy through comparison with a variety of experimental test data, we seek opportunities to utilize the technology in providing modeling and simulation services to DoD, NASA, and contractors developing flight systems for extreme environments.
