As of Jun 9, 2026, the average hourly pay for fluid structure interaction internship in the United States is $19.34, according to ZipRecruiter salary data. Most workers in this role earn between $15.38 and $21.63 per hour, depending on experience, location, and employer.

What is a Fluid Structure Interaction Internship?

A Fluid Structure Interaction (FSI) Internship is a temporary position designed for students or recent graduates to gain hands-on experience in studying how fluids (like water or air) interact with solid structures. Interns typically assist with simulations, modeling, and analysis using specialized software to predict and understand these interactions. This role is common in industries such as aerospace, civil engineering, and biomedical engineering, where understanding FSI is critical for designing safe and efficient products or systems.

What is the difference between Fluid Structure Interaction Internship vs Fluid Dynamics Engineer?

AspectFluid Structure Interaction InternshipFluid Dynamics Engineer
Required CredentialsTypically pursuing or recent graduate in Mechanical, Aerospace, or Civil EngineeringBachelor's or Master's in Mechanical, Aerospace, or Civil Engineering; often with specialized fluid dynamics coursework
Work EnvironmentResearch labs, internship programs, collaborative projects with engineering teamsDesign offices, research labs, industrial settings, project-based work
Industry UsageInternship roles in aerospace, automotive, civil engineering firmsFull-time roles in aerospace, automotive, energy, and research sectors

While both roles involve fluid mechanics, a Fluid Structure Interaction Internship focuses on gaining practical experience in simulating and analyzing interactions between fluids and structures, often as part of an internship program. A Fluid Dynamics Engineer, on the other hand, is a full-time professional responsible for designing, analyzing, and optimizing fluid systems. The internship provides foundational exposure, whereas the engineer role involves advanced responsibilities and project leadership.

What are the key skills and qualifications needed to thrive as a Fluid Structure Interaction Intern, and why are they important?

To thrive as a Fluid Structure Interaction Intern, you need a strong background in mechanical or aerospace engineering, applied mathematics, or related fields, along with knowledge of fluid dynamics and structural mechanics. Familiarity with simulation tools such as ANSYS, Abaqus, or COMSOL, and programming languages like Python or MATLAB, is typically required. Strong analytical thinking, problem-solving abilities, and effective communication skills set candidates apart. These competencies are vital for accurately modeling complex interactions and collaborating with multidisciplinary teams to drive innovative engineering solutions.

What typical projects or tasks can I expect to work on during a Fluid Structure Interaction Internship?

As a Fluid Structure Interaction (FSI) intern, you can expect to contribute to projects involving the simulation and analysis of how fluids interact with solid structures. This often includes setting up and running computational models using FSI software, analyzing simulation results, and collaborating with engineers from both fluid dynamics and structural teams. Interns may also assist in validating computational results with experimental data and help optimize designs based on simulation insights. These experiences provide a strong foundation for understanding interdisciplinary engineering challenges and can open doors to advanced roles in simulation and analysis.

Job description

Overview
VTG is seeking a Senior Test & Evaluation Engineer in Washington, DC (near Navy Yard) to provide Engineering Support Services to Engineers and Subject Matter Experts in support of the Conventional Prompt Strike (CPS) Program under the Department of Navy. Position a hybrid, onsite with occasional telework each week. The candidate will be supporting multiple engineering disciplines such as the following but not limited to: Mechanical, Electrical, Systems, Information Systems, Navigation, Flight Software, Industrial, Re-entry hardware and Flight Termination Systems. This candidate will provide more strategic support to the engineering team and leadership.
What will you do?
Ideal candidate will have Test & Eval Engineering experience as well as Program Office knowledge and understanding for Financials/budgeting and costing as well as the five phases of the Acquisition path.
  • Ability to describe the System Engineering "V" (the graphical model of the system development lifecycle that illustrates the relationship between development phases and testing phases, forming a "V" shape)
  • Understands the purpose of a System Engineering Technical Review (SETR) series (formal, event-driven reviews that assess a system's technical health, design maturity, risks, and readiness to proceed through a program's acquisition lifecycle)
  • Understands the purpose of the Test & Evaluation Master Plan (TEMP) or Master Test Strategy (MTS)
  • Technical support for hardware testing, software testing, modeling and simulation, and flight-testing.
  • Assist in the development of the Test and Evaluation Master Plan (TEMP) and equivalent documents, modeling and simulation verification, validation and accreditation plans, systems requirements verification plans, safety packages, and test planning briefing packages.
  • Support the entire test cycle from test planning, security, execution, analysis, and reporting to ensure tests are conducted effectively.
  • Support component testing for flight systems, platform systems and integration testing to ensure components work together for the weapon system.
  • Support subsystem and system level testing, and the development and execution of capability validation plans, to include, reporting on the program's phase of development and status towards verifying achievement of Weapon System Requirements.
  • Test engineering services to assist in the planning and execution of government test events, support the oversight of contractor developmental testing, and conduct assessments and provide recommendations regarding test and modeling activities. This support requires access to Threat and Engineering data classified up to TS/SCI.
  • Prepare studies, plans, and analysis in support of government test and engineering efforts.
  • Deliver monthly reports to include:
    • SCIENTIFIC AND TECHNICAL REPORTS
    • TECHNICAL REPORTS- STUDY-SERVICES
    • REVISIONS TO EXISTING GOVERNMENT DOCUMENTS

Do you have what it takes?
Required skills:
  • Must have one of the following:
    • a) A bachelor's degree in a relevant field and 11 years of professional/internship engineering experience, OR
    • b) A master's degree in a relevant field and at least 10 years of professional experience
  • Must have an active Secret level clearance and ability to sustain a Top Secret with SCI access.
  • Must be a US Citizen
  • Must have experience with MS Office Suite (Excel, PowerPoint and Word)
  • Excellent communication written and oral
  • Strong critical thinking skills to analyze information, identify biases, evaluate evidence and tolerate ambiguity.
  • Must be able to travel up to 25% in CONUS

Preferred skills:
  • Ideal candidate will have an understanding of any, or some of the following Engineering Disciplines: Electrical and Mechanical Design, Navigation, Guidance, and Control, Telemetry and Instrumentation, Flight Software, Re-entry Hardware, and Flight Termination Systems, Requirement Definition, Allocation, and Verification, Mechanical, Electrical, and Software Interfaces
  • Familiarity with the concepts and mathematics associated with a design of experiments (DoE). That ties directly to the events captured in a TEMP.
  • Experience with any of the following: Computational Fluid Dynamics especially for aerodynamic high-speed flows, Finite Element Analysis and solid mechanics, Fluid Structure Interaction, Flight dynamics and trajectory calculations (formulated in six degrees of freedom ("6DoF"), Ballistics, Penetration mechanics, Combustion and Thermodynamics
  • AutoCAD for engineering designs and architecture
