Stress concentration at a cutout: von Mises stress, plate in uniaxial tension.

Services

Analysis that answers the engineering question.

Every project starts with the decision you need to make. The model, the mesh and the report are built to support that decision. Nothing more, nothing less.

See project examples

Structural FEA

Stress, deflection, contact and margins of safety for aerospace hardware, pressurized housings, valves, brackets, weldments and skids, always backed by hand calculations.

Computational Fluid Dynamics

Internal and external flow, pressure drop, flow distribution and aerodynamic loads for valves, manifolds, pumps and ducts.

Compressible Flow

Gas-system flow rates, choked flow, orifice and valve sizing, and safety assessment for hydrogen, oxygen, nitrogen and air systems.

Thermal Management

Heat rejection and heat recovery strategies, conduction and convection modeling, heat exchanger sizing and thermal stress.

Vibration & Fatigue

Modal, sine, random vibration and shock response, with cyclic fatigue and endurance life assessment for components in harsh environments.

Electromagnetic Simulation

Permanent magnet and magnetic circuit modeling for sensors, chip detectors and actuators.

Qualification Testing

Test procedures for DO-160G and MIL-STD-810

Analysis predicts; testing proves. We write qualification, acceptance and environmental stress screening procedures to RTCA DO-160G and MIL-STD-810. Each one is built around your specification, ready for the test lab and written to hold up in customer and certification review.

Every analysis we run is planned with the test that will validate it, so the predicted margins and the test levels tell the same story.

Engineering Documentation

The paperwork that gets hardware approved

Aerospace programs run on documentation as much as on hardware. We prepare the reports, analyses and checklists that OEMs, prime contractors and the FAA expect, in the formats they expect.
