News & Events-Frazer-Nash provides collective protection concepts to Dstl

Frazer-Nash has provided the Defence Science and Technology Laboratory (Dstl) with a range of concept designs for future transportable Collective Protection (COLPRO) systems for the armed forces.

COLPRO systems create a protective environment against chemical, biological and radiological threats, allowing military personnel to move freely within a toxic free area, without having to wear individual protective equipment.

Dstl asked Frazer-Nash to identify and develop novel concept designs for transportable COLPRO systems at three sizes: small (to house 20 personnel), medium (to house 50 personnel) and large (to house 250 personnel).

After undertaking an in-depth literature review of a range of novel transportable building structures, the team assessed the requirements for transportable COLPRO to generate the criteria with which to evaluate the design options. It was hoped that the new designs would address some of the issues faced by the current systems, such as the time taken to erect and strike, the size and weight of units, restricted space and a lack of modularity.

In addition to protection from chemical and biological agents, key requirements for the COLPRO systems included decontamination areas, breathable air quality, and that it functioned as a stand-alone structure.

Using input from Dstl and subject matter experts, the team generated a wide variety of ideas which were developed into six small, eight medium, and seven large concept designs. One concept for each size was produced as a Computer Aided Design (CAD) model, and a scale model prototype was built as a further demonstration of one of the concept designs.

The preferred large and medium designs offered a modular form, with a large area capable of housing vehicles, but only required a small number of personnel to erect and strike the systems. The chosen small-sized concept offered a self-supporting structure with relatively few parts, rigid panels which are more durable and easier to seal, and rapid strike and erect.

Further work is now planned to develop the designs, prototype at scale and test in the field, to ensure they meet the needs of the military personnel who will be using them.
