Large-Span Inflatable Hangar — Concept Comparison
Anonymised project · Undisclosed
Evaluation purpose
A large-span aviation enclosure was evaluated using both low-pressure and high-pressure inflatable concepts. The purpose was to identify which structure better matched aircraft clearance, door operation, long-term deployment, environmental loads, logistics, and maintenance needs.
Concepts considered
Low-pressure modular concept
The low-pressure option used interconnected inflatable wall sections. Its principal advantages were lower initial system complexity, faster production, compact transport, and rapid deployment.
High-pressure air-beam concept
The high-pressure option used large-diameter air beams as the primary frame with a separate high-strength outer membrane. The design supported partial or full end-door opening and offered greater geometry stability for aviation clearances and longer deployments.
Decision matrix
| Criterion | Low-pressure concept | High-pressure concept |
|---|---|---|
| Initial system cost | Lower | Higher |
| Structural rigidity | Moderate | High |
| Pressure retention | More frequent checks | Longer retention interval |
| Development cycle | Shorter | Longer because of project-specific engineering |
| Aviation-maintenance suitability | Basic or temporary enclosure | Better fit for large span and controlled clearances |
Inputs required before final design
- Aircraft envelope and maintenance clearances
- Door-open aircraft position
- Deployment duration and assembly cycles
- Wind, snow, temperature, rainfall, corrosion, and altitude conditions
- Fire classification and insurance documentation
- Ground conditions, anchor design, access routes, and transport limits
Evaluation conclusion
The high-pressure concept was the stronger technical candidate for structural stability and longer deployment, while the low-pressure concept remained viable where lower cost, shorter lead time, and temporary use had priority. No final selection is stated because the final site, geometry, and compliance requirements were not fixed in the source material.
