Electrification and hybridisation will give tactical vehicles new capabilities in the field. To this end, Rolls-Royce’s new mtu hybrid drive combines the advantages of a high-performance diesel engine with those of a battery-electric drive. The highly integrated propulsion system requires comparatively little installation space in the vehicle in order to maximise the volume available for equipment and crew. The core of the solution is a highly mobile and extremely compact drive solution, taking into account increasing cost pressure, tight budgets and the need for significantly larger vehicle fleets.
For quiet operation, for example in a concealed position, the high-performance batteries previously charged in diesel mode, supply the vehicle’s electrical and electronic systems. This is done without the noise and thermal footprint of the diesel engine - and over a longer period of time. This makes the vehicle more difficult to locate for enemy reconnaissance. The so-called “anti-idling” mode not only ensures better camouflage of the vehicle, but also significantly reduces fuel consumption when the vehicle is on standby. The range of the vehicles and the downstream logistics chain for refuelling the vehicles are optimised.
The advantages of “mild” hybridisation are demonstrated by the combined drive on slow journeys, when the vehicle tracks generate little noise. The noise generated by the drive is reduced to a minimum, making it considerably more difficult to detect the vehicle. Rolls-Royce uses a specially developed and customised silencer in combination with the hybrid main propulsion. In combined operation, the electric propulsion also serves as a booster for highly dynamic acceleration, noise-reduced low-speed driving or even high-speed driving. “This allows us to utilise the advantages of hybridisation in all operating modes,” emphasises Müller.
