Aerospace Structures
Metallic & Composite spacecraft, airframe, wing box, and secondary structure
Finite Element Analysis
Linear, non-linear, dynamic, thermal, buckling, vibroacoustic and fatigue analyses
Research & Development
Concept exploration, feasibility and prototyping to de-risk programs.
Testing & Validation
Static, fatigue, vibration and environmental test planning & execution.
Design Optimization
Optimizing design to meet stiffness and loading requirements while maintaining lowest mass, lowest cost, ease of manufacturability.
Deep technical range.
The disciplines behind every deliverable — modeled to industry codes and validated by test.
Composite Analysis
Ply-by-ply layup optimization and damage tolerance.
Thermal Strength
Thermal stresses, and CTE mismatch solutions
Non-linear Dynamics
Impact, crash, drop and explicit simulations.
Fatigue & Fracture
S-N, strain-life, crack growth (DTA).
Optimization
Topology, size and shape optimization for weight.
MBD & Kinematics
Mechanism motion, contact and load extraction.
A disciplined path from idea to hardware.
Discover
Requirements, constraints, and success metrics captured with your team.
Design
Concepts explored in CAD; trade studies quantified against your KPIs.
Analyze
FEA predict performance long before hardware exists.
Test
Physical validation closes the loop and de-risks hardware qualification.
Deliver
Reports, drawings and models handed over — ready for production.
Trusted across regulated industries.
Aerospace
Commercial, business jets, UAVs and space structures.
Automotive
EV platforms, chassis, BIW and crashworthiness.
Industrial
Rotating equipment, pressure vessels, structures.
Space & Defense
Launch vehicles, satellites, mission-critical hardware.
Energy
Wind, oil & gas, and power generation systems.
Medical Devices
Precision components, body implants, and life-critical structures
See failure before it happens.

What our clients say.
SOLIENG INC. provided comprehensive design assistance to optimize the primary structure of our spacecraft. Their engineers determined the most effective design options for the primary structure: the sizing and material selection for the spacecraft's primary structure, the number of joints required between panels, the thickness of honeycomb panels …etc. Their work culminated in a well-defined overall structure and payload support design for the spacecraft.
We utilized SOLIENG INC. for mechanical engineering support, and expertise to perform structural dynamics tasks. SOLIENG’s team completed all efforts including structural static and dynamic analyses on time professionally with very little direction required. The SOLIENG team is highly knowledgeable and very supportive. The SOLIENG team understood our goals and helped us achieve them quickly at a great value.
We requested SOLIENG’s team to support a series of mechanical analysis tasks including the creation of unit level models and re-evaluation of the full space vehicle model where the incumbent team had fallen short. The SOLIENG team was able to identify where the incumbent team had fallen short and was able to provide recommendations on how to correct the problem. SOLIENG’s team impressed our customer sufficiently to where they hired SOLIENG for additional work
Compliance woven into every deliverable.
Engineers who've done it before.
Our team blends PhDs in structural mechanics, ex-OEM stress leads, and specialists in composites and dynamics. When we say senior, we mean it.
Build the future of flight.
Frequently asked.
What industries do you serve?
Primarily aerospace and mechanical — including automotive, space, defense, energy and medical devices.
Can you sign NDAs and support ITAR programs?
Yes. We work under NDA by default and are structured to support ITAR-controlled programs.
Do you work on-site?
Both. Our engineers can embed with your team or deliver fully remote from our facilities.
