Rolls-Royce has successfully demonstrated 'deep magazine' power capability for directed energy applications, powering multiple, extended laser field tests in collaboration with
Deep magazine power capability is crucial for directed energy applications, which can be limited by battery-only systems that require recharging or replacement of batteries after a short period of operation. The Rolls-Royce ColdFireTM system includes both battery-powered and near-continuous firing modes, through a compact and fuel-efficient Rolls-Royce M250 gas turbine engine which provides consistent, extended power to operate the laser application.
Powered by the Rolls-Royce system,
Rolls-Royce developed and tested the ColdFireTM system for over 10 years with
Rolls-Royce is an industry leader in thermal management - the company's advanced gas-turbine engines operate at temperatures far greater than the melting point of metal. That requires sophisticated engineering technology that allows engines to operate safely and effectively for thousands of hours. Rolls-Royce has adapted this proven thermal management knowledge into the ColdFireTM system.
Rolls-Royce ColdFireTM is a suite of world-class power and thermal options for any directed energy system, with technology ready now and tailored to the needs of the system. With field-proven laser and platform integration, ColdFireTM is suitable for land, sea or air systems, and features thermal and power options for specific customer needs. Directed energy systems offer low cost per shot and reduced logistical burdens, while offering compelling capabilities against today's stressing threats including counter-hypersonic, and are versatile and scalable. Regardless of power sources or platform, thermal management integration with the laser is critical to system effectiveness.
The ColdFireTM technology was developed in the company's LibertyWorks advanced technology unit based in
