To counter advances in adversary technologies and ensure aircraft survivability and weapon lethality, ATA Engineering has created a software tool for predicting the influence of complex rotorcraft flows on aircraft electro-optic/infrared (EO/IR) signatures. The Rotorcraft Advanced Signature Prediction (RASP) toolkit incorporates leading computational fluid dynamics and EO/IR modeling solvers in a modular, variable-fidelity framework for rotorcraft plume and signature analysis. The technology provides greater realism in computational EO/IR signature prediction by accounting for the interaction of rotorcraft downwash, engine plume asymmetry, full-body thermal state, and environmental effects. ATA delivers innovative simulation and testing solutions to DoD agencies and their contractors for mission-critical systems. Available at no cost to these customers, RASP’s multidisciplinary approach provides greatly improved accuracy of rotorcraft EO/IR signature prediction over existing methods.
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, 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.
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.
FlashCal™, an automated system for calibrating the structural health monitoring sensors aboard fighter aircraft, provides ground-based calibration without the cost of full-scale load rigs and with better accuracy than in-flight calibration. FlashCal ensures accurate flight load measurements and expended fatigue life assessments. ATA, an engineering consulting firm providing innovative solutions through test- and analysis-driven design of mechanical and aerospace systems, designed FlashCal for extensibility to any aircraft with integrated structural health sensors, and the F/A-18's demanding missions and ongoing life extension program make it an ideal initial application. A prototype successfully calibrated several fleet aircraft, and production units are being developed for Navy maintenance depot deployment. ATA seeks DoD and prime integrator relationships to explore adaptations to other air platforms and integration at production facilities.
