Defense MTU engines in demand for light military vehicles Not simply lightweights So-called light tracked and wheeled vehicles are getting heavier and heavier. So much so that they now need more power reserves. But it’s no easy task producing an engine with the right amount of power for such vehicles. MTU supplies bespoke units for the job in the shape of the Series 106 and 199. As a result of technical advances, light military vehicles have put on a considerable amount of weight. To begin with, it’s to do with their protective systems, but it’s also because of recently developed new equipment that now has to be carried by the vehicles. charger, sump, intercooler and others are also individually integrated to suit the client’s requirements. As well as the demand for the smallest possible dimensions, engine performance is always an essential factor in view of the upward trend in vehicle weights. The MTU Series 106 and Series 199 offer power outputs ranging from 160 to 530 kilowatts and represent the ideal engine solution for this type of vehicle. “Most of the time we don’t supply an off-the-peg engine,” stresses Knut Müller, Head of Defense at MTU. Components such as turbo- Enhanced armor and protection. For the 20 to 30-tonne vehicles, weight-saving design was the prime consideration up to now. But that concept has now given way to the current demands of the military forces. Today many of them no longer deploy unarmored vehicles in combat zones. Experience in Iraq, Afghanistan and other volatile regions has shown that the risk of attack by improvised explosive devices (IEDs) that endanger the lives of service personnel is too great. Comprehensive protection is therefore the most important consideration. Because of the threat levels, vehicles are now more heavily armored and provided with additional protection against mines. But more armor means more weight. Added to that are new tactical and technological requirements that pay no regard to vehicle size. The soldiers in action rely on the vehicle being able to carry all the equipment they need. In addition, items such as reconnaissance devices and auxiliary electronic equipment are indispensable in a modern military vehicle. The consequence is that the vehicle weights have increased by well over ten percent in some cases – and that a higher-powered engine must therefore be chosen. The Piranha V sets new standards with its power-enhanced MTU 6V 199 engine and starter/generator. The Husky mine detection and clearance vehicle is produced in South Africa and used successfully by countries such as Canada and the USA to protect troops and vehicle convoys. Its motive power is provided by an MTU Type 6R 106 engine producing 150 kW. «the Protective measures and technical equipment make vehicles more than ten percent heavier in some cases, and that demands higher-powered engines. » MTU Report 02/10 I 47 1 1 2 Defense 1, 2 Since 2009 the Fuchs armored personnel carrier has been undergoing trials in the United Arab Emirates where it has been exposed to extremes of climate and terrain. Fortunately the MTU Series 106 and especially the Series 199 can offer engines with sufficient reserves even for such escalated demands. The South African Husky is an example of an agile vehicle for which MTU supplies a compact power unit in the shape of the Type 6R 106. It is used, for instance, by Canadian and US forces to protect personnel and vehicle convoys in Iraq and Afghanistan. With its 150-kilowatt Type 6R 106 engine it is untroubled by rough terrain or steep gradients. Tognum subsidiary MTU South Africa has sold several hundred engines for the mine detection and clearance vehicle to the manufacturers DCD Dorbyl in Johannesburg. 2 1 The Fuchs armord personnel carrier is an extremely versatile multi-purpose vehicle. 2 The vehicle is powered by the new MTU 6V 199 engine producing 456 hp (335 kw). Versatile: The boxer. The Boxer multirole armored vehicle (MRAV) can be transported rapidly by plane to any deployment zone. Its 530-kilowatt (720-hp) 8-cylinder engine makes the 33tonner highly agile and capable of a top speed of 103 kilometers per hour despite its weight. Powerful Fuchs. The Fuchs armored personnel carrier used since the 1970s is a highly versatile vehicle. The standard version serves as a troop transporter. The Fuchs is an example of how military vehicles have been constantly modernized over their long service lives of at least 30 years. Along the way they are provided with new functions and more protection, so that they need more powerful engines. Whereas the engine fitted 48 I MTU Report 02/10 in the earliest versions was an OM 402 capable of 320 hp, the latest power unit is a Type 6V 199 delivering 456 hp (335 kilowatts) and substantially greater reserves. Technical highlights of Piranha V. An advanced development offering plenty of technical highlights, especially in powertrain terms, is the Piranha V wheeled vehicle. Once again, the aspect of greater protection and the consequent heavier vehicle weight plays a significant role. Motive power is provided by a power-enhanced 430-kilowatt Type 6V 199 engine. The power increase from 400 to 430 kilowatts represents 2,200 Nm of torque from its diesel engine and the starter/generator, the Piranha V sets new standards in its class. With the Series 199 engines, MTU is ideally equipped to meet the demands of future military vehicle missions. Providing comprehensive advice and support on the design of new vehicles or the repowering of existing vehicles, the company is ideally qualified to meet the needs of all clients looking to install maximum performance in the minimum of space. «vehicles Protective measures and technical equipment make the more than ten percent heavier in some cases, and that demands higher-powered engines. » an outstanding engineering achievement. “We exploited every bit of the basic engine’s potential,” Knut Müller relates. The Piranha V is also the first wheeled military vehicle in the world to use a starter/generator. The starter/generator produces an electrical output of 120 kilowatts which supplies all the vehicle’s electricity requirements. Due to the demand for more electronic equipment on the vehicle, the need for electrical energy is greater as well.
