Rolls-Royce hybrid engine concept could boost tank stealth

Based around the company’s mtu diesel engines, the hybrid drive concept will see high-performance batteries charged when the engine is running on diesel power. Vehicles can then operate in an ‘anti-idling’ all-electric mode when stationary, with electrical power delivered silently. According to Rolls, this will provide significant tactical benefits, reducing vehicle noise and thermal footprint while cutting fuel consumption.

The hybrid drive will also enable tanks to travel with reduced noise at slow speeds, assisted by a customised silencer. When more power is required, for example in combat, the electrical power can be tapped to help boost acceleration and top-end speed.

“This allows us to utilise the advantages of hybridisation in all operating modes,” said Knut Müller, senior vice president, Global Governmental Business at Rolls-Royce Power Systems.

“Future armoured military land vehicles will require more power for propulsion and on-board power supply for the electronic systems. At the same time, they will be designed for a different tactical approach in the field. Our future mtu propulsion solutions for this application take both of these requirements into account.”
