Modeling & Simulation

What If?

At ERC, modeling and simulation (M&S) are part of our DNA. Since our founding in 1988, we have provided our Defense and Space customers with practical M&S solutions that reduce costs, increase efficiency, improve resource utilization, and decrease risk. Our engineers understand the strengths and limitations of the models we apply and use this expertise to comprehend and analyze results and help our customers make better, faster decisions.

ERC’s proficiency in M&S helps our customers evaluate system effectiveness, manage the risk associated with critical decisions, and efficiently design new missions. From single-user desktop models to a collection of complicated models shared across groups or organizations, ERC applies our vast expertise across a wide gamut of platforms and applications.

How We Do It

Ahead of the Curve

How do you make better-informed decisions early in the design cycle? At Eglin Air Force Base, ERC applied modeling and simulation and our engineering expertise to analyze the design of an upcoming hypersonic weapon. As a result of our M&S, we determined that the material specified in the design would not withstand the structural forces exerted during flight. By specifying a new material before building the weapon, the Air Force saved a significant amount of time and money and delivered new capabilities faster to the warfighter.   

Fighting Flutter

Flutter has plagued aviation for years. A result of aerodynamic and inertial forces, flutter is a complex problem that typically manifests itself in the vibration of the wing of an aircraft around which air is flowing. It can result in damage to the aircraft structure or potentially a crash.

Working with the Department of Defense, ERC applies modeling and simulation techniques to study aerodynamic flutter for fixed-wing aircraft. Modeling flutter for high-speed flight is extremely difficult due to the high nonlinearities involved. ERC is at the forefront of applying M&S to address this challenging undertaking. In addition, we back our modeling results with our comprehensive test and evaluation capabilities. Furthermore, we continually investigate new ways to improve our modeling techniques to help ensure that our pilots are safe and aircraft perform as expected during critical missions.
