Integrated High Power Generation for the Joint Light Tactical Vehicle

OUSD (R&E) MODERNIZATION PRIORITY: General Warfighting Requirements (GWR) TECHNOLOGY AREA(S): Ground / Sea Vehicles OBJECTIVE: Develop an integrated, compact, prime engine-driven high power generation system for the Joint Light Tactical Vehicle (JLTV) that will support both onboard and export electrical power capabilities while fitting within the confines of the chassis to meet expected power demands and allow for future mission growth. DESCRIPTION: The JLTV is currently capable of generating between 12.8-14.6 kW of electrical power and while this capability allows for future vehicle system growth, it is insufficient to support future systems. Currently the system is limited by the onboard power capability of the JLTV, forcing us to either accept a reduced capability or carry an additional standalone generator. These approaches unnecessarily restrict capability and/or complicate the mission by reducing mobility, fuel efficiency, reliability, and cargo capacity. Vehicle integrated power generation systems will be needed to power future Missile and Air Defense systems, Counter Unmanned Arial Systems (C-UAS), and Command and Control (C2) systems without burdening the mission with standalone generators. The system requirements are: Integrated electrical power generation system kit driven by the existing JLTV General Motors Duramax 6.6L Turbodiesel V-8 engine Power output of 50 kW Threshold (T); 70 kW Objective (O), at 28 volts direct current (VDC) while stationary and on the move Stationary power output shall not require the engine to exceed tactical idle (1800 RPM) Compatible with 28-VDC tactical electrical systems and 14-VDC vehicle electrical systems Physical size of generator no larger than 11 H x 11 W x 16 D Physical weight of export power system less than 225 lbs. Operate in hot and cold mission environments between -40 C to 52 C Operate in a JLTV environment to include: Primary Roads, Secondary Roads, Trails and Off-Road / Cross-Country. Electrical component and connections shall comply with MIL-STD-810H where appropriate and have an ingress protection rating of IP67 or higher in accordance with American National Standards Institute (ANSI) International Electrotechnical Commission (IEC) 60529-2004 Initial quantities for these systems is approximately 66, but could be higher if other Marine Corps platforms and other services decide to use this capability. Quantities will also depend on the cost of the conversion kit estimated to be between $50K and $75K. PHASE I: Develop concept(s) for a generator technology and its supporting control equipment that can meet the system requirements in the Description. Demonstrate the feasibility of the concept(s) in meeting Marine Corps needs. Establish that the concepts can be developed into a useful product for the Marine Corps. Feasibility will be established by material testing and/or analytical modeling, as appropriate. Provide a Phase II development plan with performance goals and key technical milestones, and that addresses technical risk reduction. PHASE II: Develop a full-scale prototype for evaluation. Evaluate the prototype through bench or lab testing to determine its capability in meeting the performance goals defined in the Phase II development plan and the Marine Corps requirement for the integrated power generation system. System performance shall be demonstrated through prototype evaluation and modeling or analytical methods over the required range of parameters including numerous deployment cycles. Evaluate the results of the demonstration and refine the design as necessary. Conduct on-vehicle testing in a relevant environment. Evaluate and compare the results to Marine Corps requirements. Prepare a Phase III development plan to transition the technology for Marine Corps use. PHASE III DUAL USE APPLICATIONS: Provide support to the Marine Corps in transitioning the technology for Marine Corps use. Refine a power generation system for further evaluation and determine its effectiveness in an operationally relevant environment. Support the Marine Corps test and evaluation program to qualify the system for Marine Corps use. Commercial applications include law enforcement vehicles, search and rescue vehicles, tractor trailers, and general automotive platforms to provide integrated power capability and reduction of both weight and space claim, supporting a more demanding future mobile power environment.
