ADS GmbH defines the next generation of Active Protection Systems (APS) by the rigorous application of highest safety standards

The world’s first independently assessed "functionally safe" APS

ADS Gesellschaft für aktive Schutzsysteme mbH (ADS GmbH), the pioneer in reliable and precise hard-kill Active Protection Systems (APS), today announces it has achieved a world first; the design and development of an APS to the highest safety standard, IEC61508. In 2018 ADS-Gen3 plans to be certified to IEC61508 SIL 3 (Safety Integrity Level), to be independently assessed by auditing firm tms (technisch-mathematische studiengesellschaft mbH) using the German Armed Forces’ assessment methodology for weaponry safety.

After seven years of risk-assessed design, development and system testing, ADS-Gen3 delivers world leading consistent APS defensive performance, validating defensive operation as succeeding in at least 999 of 1,000 system responses, and potentially as high as 9,999 in 10,000 system actions. IEC61508 SIL 3 is the same safety integrity level used to ensure the explosives in our airbags in our cars don’t fire inadvertently, yet respond in critical situations exactly when needed in the event of an accident.

Further, the system is designed to run continuously safely, thus assuring that dismounted crew or support infantry are not put at unnecessary risk by the APS automated defensive firing capabilities. The reliability of functional safety in ADS-Gen3 aims at a level higher than daily used elevators, critical components in public transport or traffic light controls.

"Functional safety is not about whether a system is working well in its field and delivering an expected performance – it’s about whether it is safe for all of us to use such system – as operator or as any human being which simply happens to be nearby", clarifies Dr. Ronald Meixner, lead engineer for the ADS design.

The combination of defensive performance tested by the NATO STANAG group coupled with the highest degree of regard for the IEC61508 safety of those around an APS defended vehicle, defines a new era for APS design. The achievement of these different APS safety as well as system performance levels brings the same level of confidence we give to our car design to keep us safe, to the APS sector, marking a fundamental shift from new technology adoption caution to an assurance of the familiar and proven.

"With this announcement ADS GmbH confirms its technical pioneering leadership in APS design and development," said Stefan Haase, CEO, "by bringing our automotive engineering heritage and discipline to the APS sector we expect to reduce market adoption timeframes, enabling the rapid deployment of APS’s to defend sorely pressed vehicle assets from the spectre of the insurgent with an RPG or ATGM threats."

During the test, an RPG7 rocket propelled grenade was fired from a distance of 18m at an ADS-equipped Fuchs/Fox 1A8 armored personnel carrier (APC) being towed at 20 km/h. The RPG7 warhead is a shaped charge with 0.73 kg of the explosive HMX which will penetrate over half a meter of rolled homogeneous armor.

The RPG7 travels at 110 m/s before its rocket motor fires. The ADS thus had only a tenth of a second from launch to recognize the threat, confirm it as a real threat, decide on a response, and activate the appropriate countermeasure.

As the image shows, the AMAP-ADS successfully destroyed the RPG7 in close proximity to the APC. As the ADS operation does not generate fragments or other debris, the observers were unscathed, and an Asian representative has now ordered the system for his country.

The above sequence of three high-speed video frames shows the destruction taking place. The first frame shows the RPG7 projectile approaching the Fuchs/Fox APC. The second frame is taken just after activation of the ADS, showing the explosive operation and destroying the RPG7 in mid-air adjacent to the surface of the vehicle. The final frame shows the post-test largely undamaged APC.

The AMAP-ADS protects a complete hemisphere with a reaction time of roughly 500 microseconds, allowing it to react not only to RPGs, but to virtually any close-in threat (anti-tank guided missiles, kinetic energy projectiles, explosively formed penetrators, IEDs, etc.). Source: newatlas.com
