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 vehicles 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.
Benefit: The primary benefit from the proposed research is an additional 50+kW of on-vehicle electrical power to enhance JLTV capabilities with minimal weight impact. The solution provides additional electrical power to support advance technology, supply power intensive systems and for export power, extending the JLTVs mission profile. Defense
Benefits: Benefits include increased mission capability, reduced system weight, and reduced logistics by eliminating APU requirements and associated fuel. Given that fuel is the second-highest battlefield operational need behind water, reduced fuel consumption provides greater freedom of action. The ultimate focus is enabling and reducing risk to the warfighter as the end-user. The warfighter receives further benefits including size and weight reductions, increased payloads, increased mobility, easier handling and reduced logistics risk, including reducing the number of vehicles and the warfighters exposure. Non-Defense
Benefits: Commercial transportation vehicles benefit from improved electrical power with reduced fuel consumption and associated greenhouse gases. The solution can benefit nearly 15 million commercial vehicles including first responders, ambulances, refrigeration, and other specialty vehicles with requirements beyond what is typically available from on-engine alternators. The transition plan includes engagement of strategic partners in industrial, oilfield, agricultural and construction with potential revenues of over $20MM following commercialization.
