Aerospace Structural Integrity Engineering
Structural integrity engineering for aerospace hardware
Fidelis Aerospace practices structural integrity engineering through three distinct pathways for aerospace suppliers, component manufacturers, modifiers, integrators, and growing hardware teams: engineering services, consulting & advisory, and applied research.
Bring the hardware, the engineering decision, and the evidence available today. Fidelis will help identify whether the need belongs in services, consulting & advisory, research, or a coordinated combination, then define and execute the appropriate scope with experienced judgment.
Direct Senior Execution | Independent Technical Judgement
When structural work needs experienced attention
Aerospace programs often outsource structural integrity work when the internal team lacks a specific specialty, the workload exceeds available capacity, or an important hardware decision needs an independent senior perspective. Fidelis supports those moments without requiring the client to build and maintain every capability in-house.
Common reasons teams contact Fidelis
- A new component, installation, or design change needs structural substantiation.
- The team needs finite element analysis but does not have the right internal model, experience, or capacity.
- A low or negative margin must be understood and resolved before release, test, or delivery.
- Fatigue life is uncertain under the expected loading spectrum or mission usage.
- A crack, defect, nonconformance, or test anomaly requires fracture or damage-tolerance assessment.
- A program needs direct access to experienced structural judgment for a defined technical problem.
Three distinct practices
Services
Execution-focused structural integrity engineering: Structural Analysis, Finite Element Analysis, Fatigue Analysis, and Fracture Analysis for current aerospace hardware decisions.
Consulting & Advisory
Senior structural judgment for technical review, analysis strategy, anomalies, test or qualification decisions, margin recovery, and problems broader than a predefined analysis task.
Research
Applied structural integrity research and method development where methods, models, evidence, or capability must be created, matured, or validated.
Structural integrity services
Structural Analysis
Understand load paths, stresses, deflections, stability, joints, failure modes, and margins of safety using classical methods and engineering mechanics.
Finite Element Analysis
Model complex geometry, load transfer, stiffness, contact, and local response when closed-form methods are not sufficient for the decision.
Fatigue Analysis
Estimate life under repeated loading, identify durability drivers, and support design, test, qualification, usage, and maintenance decisions.
Fracture Analysis
Evaluate assumed or discovered flaws through fracture mechanics, crack-growth, residual-strength, and damage-tolerance methods.
Common outsourced structural integrity opportunities
Fidelis can support a complete analysis task or a focused portion of a larger client-controlled program. Typical opportunities include:
- Component sizing, stress analysis, and margins of safety.
- Structural substantiation for design changes, equipment installations, and modified hardware.
- FEA model development, model review, global-local analysis, and results interpretation.
- Fastener, fitting, bracket, frame, panel, joint, and attachment analysis.
- Buckling, stiffness, deflection, local stress, and load-path evaluation.
- Fatigue-life, durability, crack-growth, residual-strength, and inspection-support analysis.
- Pre-test predictions, test support, discrepancy assessment, and analysis-test correlation.
- Independent checking and senior technical review of client-generated structural work.
Built for the aerospace supply chain
Fidelis is positioned for organizations behind the major primes: the suppliers, manufacturers, modifiers, integrators, and hardware developers responsible for turning requirements into real parts, assemblies, installations, and test evidence.
Best-fit organizations
- Aerospace component and equipment manufacturers.
- Special-mission, payload, avionics, and aircraft modification organizations.
- UAS, advanced aviation, space, and defense hardware developers.
- Manufacturing, prototyping, and qualification teams with design responsibility.
- Engineering organizations that need temporary specialty capacity or independent review.
How Fidelis works
1. Start with the decision
Clarify the hardware, configuration, loading, program stage, decision, available evidence, and constraints.
2. Define the analysis needed
Select the simplest defensible methods that can answer the question, then identify required inputs, assumptions, interfaces, and verification steps.
3. Execute and verify
Perform the analysis, check the mechanics and model behavior, examine sensitivity, and document the basis of the result.
4. Communicate what the evidence supports
Provide clear conclusions, limitations, margins, risks, and recommended next actions so the client can make the engineering decision.
Experienced engineering judgment
Fidelis Aerospace is founder-led and the technical work is performed with direct senior involvement.
More than two decades of aerospace product-development experience inform the analysis of commercial aircraft, defense systems, space hardware, structural components, modifications, test articles, and high-consequence engineering decisions.
The objective is not to produce the most complicated model or the longest report. It is to understand what governs, use an appropriate method, verify the result, and give the client a useful engineering basis.
Bring the structural decision into focus
Describe the hardware, the decision ahead, and the evidence you have today. A focused technical discussion can determine whether Fidelis is a fit and what information is needed next.
Frequently Asked Questions
What structural engineering services does Fidelis Aerospace provide?
Fidelis Aerospace provides structural analysis, finite element analysis, fatigue analysis, and fracture mechanics support for aerospace hardware. The work can include sizing, substantiation, margins of safety, FEA, durability, crack-growth, residual-strength, test support, and independent technical review within an agreed scope.
Who does Fidelis Aerospace work with?
We support the aerospace supply chain: component manufacturers, equipment suppliers, modifiers, integrators, UAS and space hardware developers, and growing engineering teams that need specialized structural integrity capability or additional senior capacity.
Does Fidelis sell packaged analysis services?
No. Each engagement is scoped around the actual hardware, engineering decision, available data, schedule, and evidence required. The same service may involve a focused calculation, a detailed finite element model, a life assessment, or an integrated technical report depending on the problem.
Can Fidelis support aerospace certification or qualification?
Fidelis can provide engineering analysis, substantiation, test-support, and documentation inputs that contribute to certification or qualification efforts. Final approvals and authorized compliance findings remain with the responsible organization and appropriately authorized representatives.
