Safety, Maintainability, Reliability, & Quality Assurance (SRM&QA)
Our engineering team applies a highly-structured systems approach to engineering design, analysis, integration, configuration management, quality, safety, reliability, sustainability and testing. We focus on specific requirements and the ultimate purpose of the project or program to ensure an outcome that meets or exceeds the objectives of the project. STi’s skills in engineering design and analysis make for a practical approach to ensuring that systems are reliable and easy to maintain. We can predict product performance in detail and evaluate the effects of design changes, which results in effective, reliable, and durable products. We view reliability as an essential and integral component of product design and development.


SRM&QA has been among STi’s primary areas of expertise since the company was founded in 1985. In that time, our work has included services to clients such as the National Aeronautics Space Administration (NASA), the Missile Defense Agency (MDA), and various branches of the U.S. Department of Defense.

Systems Engineering
STi’s team of engineers works to create a comprehensive end-to-end system design. First, we work with the customer to identify all physical and functional requirements. We then synthesize those requirements and define the system’s architecture and subsequent interface details. STi personnel are thoroughly immersed in the Systems Engineering processes, tools, and technical reviews as they support their customers in the acquisition of products and services. We understand the importance of clear requirements definition and transparency through to the test, evaluation, and certification processes.
Aerospace Engineering
STi engineers have a solid background across all aerospace engineering disciples, including fluid mechanics, flight dynamics, control engineering, aeroelasticity, structures and materials science. STi currently supports customers with technical expertise in programs relating to aircraft flight dynamics, flying qualities, performance, propulsion, and computational fluid dynamics flow modeling for rotary and fixed wing aircraft. From experimental testing at model scale in wind tunnels and full scale testing on land or at sea, to computational flowfield analysis, STi offers a broad range of aerodynamics expertise.
Test and Evaluation(T&E)
STi personnel are highly experienced in testing & evaluation (T&E) and understand its role in providing knowledge to aid in managing the engineering risks involved in developing, producing, operating and sustaining complex systems. Our staff includes United States Naval Test Pilot School graduates with vast experience in helicopter, fixed wing and systems test and evaluation. We are poised to meet test and evaluation requirements for the full spectrum of systems needed by Ground, Air, Sea, or Cyber Warfighters.
Modeling and Simulation (M&S)
STi personnel have extensive experience in modeling and simulation(M&S) and test and evaluation of M&S. Our experience ranges from test and evaluation of flight simulators to the specification, procurement, and verification, validation and accreditation (VV&A) of experimental simulations. STi personnel provide our customers with comprehensive skill sets necessary for M&S requirements definition, system specification, system procurement, and system VV&A in accordance with DoD requirements using the best practices of organizations like the Defense Modeling and Simulation Office.
