Verification / from prototype through production

Aerospace Testing & Qualification

In-house qualification, validation and acceptance testing to help move pressure-vessel programs from prototype to flight- or field-ready hardware.

  • Qualification planning
  • Repeatable test evidence
  • Production acceptance

Verification Through Testing.

Mission-critical pressure vessels must demonstrate performance through repeatable test evidence. Steelhead supports aerospace and defense programs with qualification planning, test execution, data collection and production acceptance testing tied to the requirements of the specific program.

  • Proof testingPressure-vessel proof testing against the program’s requirements.
  • Burst / rupture testingHydrostatic burst and rupture testing for development and qualification.
  • Cycle & fatigue testingPressure-cycle and fatigue testing support.
  • Leak testingHelium leak and pressure-decay test methods.
  • Environmental testingThermal conditioning and environmental testing.
  • InspectionDimensional, structural and applicable non-destructive inspection.
  • InstrumentationStrain measurement and instrumentation support.
  • Materials & processesMaterial and process evaluation with failure-analysis support.
  • Production acceptanceTesting tied to the production acceptance requirements.

Program-specific qualification

The Test Plan Follows the Requirement.

Steelhead has experience supporting qualification methodologies including S-080, S-081, AIAA approaches and MIL-SPEC / MIL-STD requirements, as applicable to the program. The applicable standard, test plan, acceptance criteria and approval basis must be defined for the specific hardware.

Experience supporting a qualification methodology is not a blanket approval or certification of every vessel or application.

Engineering feedback

Prototype Through Production.

Test results feed directly back into engineering, winding-process refinement, manufacturing controls and production acceptance criteria. Keeping testing connected to development helps the program mature with fewer handoffs.

Observe the Test Article.

The approximately 15-second clip shows a vessel in a test enclosure. The vessel ruptures abruptly and the test article moves to the floor. The footage illustrates a destructive test; it does not state the pressure, acceptance criteria or outcome of a qualification program.
