Integrated High Power Generation for the Joint Light Tactical Vehicle

The US Navy requires additional electrical export power from the JLTV for both unique vehicle applications and tactical capability. The JLTV program office is introducing a larger capacity 20kW alternator, and despite its 30% increase in power output, it is less than 30% of the electrical power required for special applications. Integrating advanced high-density generators can provide an additional 50+kW of available power for the specific needs with a minimized impact on weight and vehicle performance. The proposed solution is a combination of a compact, novel, adjustable speed drive (ASD) and an advanced high density electrical generator. Driven by the vehicle’s PTO interface, and/or within the engine compartment, the system generates required power while the vehicle is stationary and on-the-move. Across the range of vehicle operation, the ASD independently controls the generator speed to optimize electrical power output. This electrical power is available to power on-board equipment, charge battery banks, or to export for other electrical demands. The solution enables the JLTV to support a variety of electrical power-heavy applications. These applications range from command centers, ambulance, other electrical driven attachments, or advanced weapon systems.
