These are platform-level descriptions, not a guarantee that every configuration shares the same pressure rating, interface or qualification basis. Where a public pressure value is not provided, consult Steelhead engineering. Commercial specifications and certifications do not automatically apply to an aerospace configuration.
Engineering & Qualification
Interfaces Are Part of the Design.
Pressure vessel selection is only the beginning. Steelhead can support sizing and trade studies, interfaces, design analysis, prototype hardware, qualification planning, testing and the transition into production.
- Define the envelopePressure, volume, available diameter and mass target.
- Review integrationPorts, mounting, gas or fluid and operating environment.
- Develop the hardwareAnalysis, prototypes and manufacturing feedback.
- Plan qualificationProgram-specific requirements, testing and production acceptance.

A Commercial Configuration
May Fit the Requirement.
For programs that do not require an aerospace-specific configuration, Steelhead’s Nomad Series provides commercial compact Type III platforms including Trek and Ranger.
Review the commercial family separately rather than assuming its specifications or certifications apply to aerospace hardware.
