WIND DATA AND FINDINGS
The Bunk House has been evaluated in a professional aerodynamic simulation, to observe its ability to remain stable under significant wind load conditions.
Simulation results (approximate):
-
Wind speed tested: 29.06 m/s (≈65 mph / 104 km/h)
-
Forward drag force: 4,870.70 N (≈496.5 kg / 1,095 lbs of horizontal force)
-
Vertical lift force: 2,214.00 N (≈225.69 kg / 497 lbs of upward force)
-
Lateral load: 432.29 N (≈44.07 kg / 97 lbs of side force)
-
Drag coefficient (Cd): 0.835
What this means:
At sustained winds of 65 mph, the structure resists roughly 1,095 lbs of forward wind pressure and 497 lbs of lift force, demonstrating strong aerodynamic resilience when properly anchored.
Why this matters:
These results show that the Bunk House is engineered to perform in demanding real-world environments, including disaster deployment and field operations. With a balanced aerodynamic profile and tested force loads, this design supports reliable field stability in severe wind scenarios when properly secured.
Note: Results are based on a professional CFD “virtual wind tunnel” test.
Real-world conditions may vary, and physical testing is recommended for mission-critical applications. A full copy of the results is available upon request.
From Flat to Firm: How Double Wall Fabric Works
When air is pumped into the Bunk House, Pod, or Sectional, each DWF chamber begins to expand from the inside out. As pressure builds, thousands of internal drop-stitch fibers straighten and pull tight, guiding the walls, ceilings, and openings into their precise engineered shapes. The flat PVC panels rise evenly, locking into rigid planes as the tension increases.
Within minutes, the entire structure transitions from a compact, folded form into solid, load-bearing walls and ceilings. The balanced pressure across the chambers distributes strength uniformly, creating a firm, stable envelope that feels comparable to a traditional framed structure. Once fully pressurized, the shelter holds its shape without poles or beams—delivering a strong, lightweight, and easily deployable space that can be packed down just as quickly when needed.
What is Double Wall Fabric?
Double Wall Fabric (DWF), also known as drop-stitch material, is a three-dimensional inflatable textile made by connecting two outer layers of fabric with thousands of tightly woven internal threads. When pressurized air fills the sealed chamber, these threads pull the layers into tension, forming a stiff, flat panel. Bunk House Structures leverages both the rigidity of DWF and the protective air space within it to build shelters that are strong, stable, and well-suited for demanding environments.
