Couplings come under attack

The sorts of hostile environment routinely faced by the military present challenges for engineering as well as personnel. An army has to be totally effective whether operating in deserts, jungles, swamps, mountains or arctic conditions. Similarly, the Huco coupling selected for position sensing in a rocket launcher control system had to prove its reliable operation in extremely aggressive environments. The brand of coupling initially chosen for the job failed consistently. A cocktail of heat, dust, debris and combustion products resulting from a missile launch created a viscous mass that completely solidified the coupling, rendering it rock hard and useless. Fortunately, couplings specialist Huco was able to engineer a simple but clever solution. The resultant coupling is based on the company’s standard 19mm diameter, stainless steel Multibeam – a design that is ideal for accommodating both angular and parallel misalignment. A stretched version of the original was made nearly double the standard length, and modified to accept a specially moulded neoprene gaiter that effectively shields the beam mechanism from debris attack.
