Harnessing Energy Absorbing Technology: Spotlight on SPIRAL Technology by Mobius Protection Systems

Energy absorbing technology is a cornerstone of modern safety and survivability innovation. At the forefront of this field is Mobius Protection Systems Ltd., an industry leader specializing in advanced energy absorbing (EA) solutions for military, automotive, aerospace, and marine applications. Among its cutting-edge technologies, the SPIRAL EA system represents a revolutionary leap, combining simplicity, performance, and adaptability to address the most extreme impact scenarios.

The Role of Energy Absorbing Technology in Blast Protection

EA systems are pivotal in protecting vehicle occupants from the catastrophic effects of explosive blasts, such as those caused by mines or improvised explosive devices (IEDs). Such events subject vehicles to accelerations of 250g to 600g, far exceeding human survivability thresholds. Mobius’s EA solutions are engineered to mitigate these forces, rapidly dissipating the immense kinetic energy created into manageable levels, ensuring passenger safety during high-impact events【6†source】【7†source】.

Introducing SPIRAL: The Heart of Mobius’s EA Innovation

At the core of Mobius’s EA portfolio is its patented SPIRAL technology. This unique system excels in high-impact scenarios, absorbing energy through controlled plastic deformation. The spiral design enables the system to withstand and adapt to extreme conditions, including multi-hit assaults, without compromising performance【7†source】.

A Broader Calibration Range

While most EA systems are designed to perform effectively when calibrated for the average male, SPIRAL technology by Mobius offers a groundbreaking advancement in inclusivity. It is designed to protect the entire range of the population—from the 5th percentile female to the 95th percentile male—without the need for any pre-calibration. This ensures a broader applicability across diverse user groups, enhancing survivability in every demographic【7†source】.

Tackling the Secondary Slam-Down Effect

In addition to handling the immediate impact wave of a blast, the SPIRAL EA system has been specially engineered to address the secondary effects of a slam-down—the violent force exerted when the vehicle, lifted by the blast, crashes back down to the ground. The SPIRAL system manages both phases of energy transfer, ensuring optimal occupant protection during both the initial explosion and the subsequent impact【7†source】.

How SPIRAL Works

The SPIRAL EA system operates using a predesigned tension threshold. Under load, the material remains rigid until the threshold is exceeded, triggering controlled plastic deformation. This deformation efficiently absorbs kinetic energy beyond the elastic region. The system’s design allows for flexibility in parameters, including material composition, cross-sectional geometry, and the number of spiral revolutions. This adaptability ensures optimal performance tailored to specific dynamic impact requirements【7†source】.

Benefits of SPIRAL Technology

• Comprehensive Protection: Calibrated to protect a wide demographic, covering the 5th percentile female to the 95th percentile male.
• Dual-Phase Energy Absorption: Effectively mitigates both the blast wave and the slam-down effect during a secondary impact.
• Compact Design: Installed under seats, the system conserves cabin space while maintaining ergonomic comfort and safety.
• Customizability: Adjustable parameters ensure that SPIRAL can meet diverse operational demands, from legacy vehicles to new models.
• Durability: Resistant to environmental degradation, the system remains effective in harsh conditions, ensuring long-term reliability.

Beyond Standard EA Solutions

Unlike traditional EA systems that rely on complex assembly or suspension components that are susceptible to wear, SPIRAL employs a simpler, yet highly-effective, design that minimizes maintenance requirements and maximizes operational readiness. After a blast event, only the deformed spiral component needs replacement, enabling rapid restoration of the system’s protective capabilities after deployment【6†source】【7†source】.

A Solution for Every Platform

Mobius Protection Systems has a proven track record of developing EA systems tailored to various platforms and applications. Whether for armored fighting vehicles, aircraft, or maritime vessels, SPIRAL technology demonstrates unmatched versatility. For example, Mobius’s floor-mounted EA solutions incorporate SPIRAL technology, offering superior blast protection while adhering to strict space and weight constraints typical of military vehicles【6†source】【7†source】.

Looking Ahead

In a world where safety cannot be compromised, Mobius Protection Systems continues to redefine what is possible with its energy absorbing technology. The SPIRAL system epitomizes the company’s ethos of innovation, simplicity, and flawless performance. With SPIRAL, Mobius offers not just a product but a promise—to safeguard lives and enhance survivability in the most challenging environments.
