OK so that is the problem and there is an obvious vehicle modification to counter the roll-over problem which is to fit stabilisers, adopting the same concept employed in a child's bicycle. [PLAIN]http://img3.imageshack.us/img3/3770/stabilisedmrap.jpg [Broken] The simplest and cheapest way to do this would be have bolt on stabilisers which could be partially unbolted to fold up when not required while driving on good flat roads but where the additional width of the stabilisers would cause problems, such as when travelling along narrow roads, needing to negotiate dense traffic such as in urban roads. The high-tech and expensive solution would be stabilisers which fold-up or deploy automatically using hydraulics at the touch of a driver's button. However, when you compare the expense of a good solution to the expense of lives lost by MRAP rollovers then it is a small price to pay. OK that idea is adapting the existing MRAPs but here is an idea for a completely new design of MRAP. The catamaran tank - an MRAP which doesn't roll over! [URL]http://www.visailing.com/newsletter/charter-chatter/issue-5/yacht-charters-images/bareboat-catamaran.jpg[/URL] A catamaran - the inspiration for a twin-hulled armoured vehicle The catamaran tank or catamaran MRAP or catamaran armoured vehicle or catamaran armored vehicle - you heard it here first! One idea I have for a completely new design to counter ground-blasts yet retain stability would be a double-hull or catamaran tank. To explain, let us describe most simply the current MRAP vehicle design as an M-shape, looking at the vehicle from the front or the rear, with a high middle, and a V-shaped hull, armoured to deflect the blasts. Well the concept of the catamaran tank is to replace the M-shape with something more like a Y''Y-shape which is a lot wider for stability and so may not be so good in narrow streets or traffic admittedly. The central double quotes in the Y"Y-shape represents a line of strong blast-chimneys up through the middle of the vehicle, from front to rear, which some of the blast could go up without splitting the vehicle in two. This twin-hull, double-hull MRAP would give two distinct cabins on the left and right of the vehicle and however high you need the vehicle to get distance from a ground blast then make the Ys bigger and so further apart which keeps stability. The leg of the Ys could have blast ventilation holes so that blast gas under the vehicle can escape to the sides as well as up the central chimneys. The more ways the blast gas can escape from under the vehicle the less force the blast will apply against the vehicle itself. The bottom of the Ys could be either wheels or tracks depending on what ground conditions you are designing the vehicle for and need to cope with. This dear forum members is the catamaran tank - my idea and you heard it here first. Copyright © Peter Dow, 26th July, 2010.
