Summary

The Department of Defense (DOD) is seeking proposals for their SBIR 24.1 BAA solicitation. The specific topic of the solicitation is "High-Temperature, High-Efficiency Electrical Starter/Generator" and it falls under the Navy branch. The objective of this solicitation is to develop a high-temperature, high-efficiency electrical starter/generator (ES/G) and a system generator control unit (GCU) to optimize heat load, output power, size, and weight of future power systems. The Navy is interested in new Electrical Power Generating System (EPGS) technologies that can increase efficiency, specific power, power density, and power capacity for 270 Vdc More-Electric Aircraft (MEA) systems. The EPGS is the main power source for MEA and should provide motoring for main engine start capabilities. The Navy is open to improvements to the existing EPGS or a new novel power generation system architecture/design. The desired generator should be able to produce 200 kW of power across a 1.00-to-1.75 speed range, with the higher region of the speed range around 24,000 rpm. It should be capable of providing stable power for continuous and intermittent power across the operating speed range and maintain typical power quality metrics. The offeror should demonstrate feasibility and performance capability during Phase I using modeling, simulation, and analysis. Phase I involves defining the generator design approach and developing an implementation plan. Phase II focuses on developing and demonstrating the generator technology that can provide 200 kW of continuous power and can be fitted into the aircraft. Phase III involves packaging and integrating the new generator for use in the aircraft, subjecting it to full qualification testing and flight test profiles. The potential impacts of this technology include increased efficiency and power capacity of the ES/G, reduction of system volume and weight, improved thermal performance, better engine and air vehicle performance, and reduced engine heat loads. Industries such as automotive, marine, industrial machinery, agricultural machinery, and construction machinery could also benefit from this technology. The solicitation is closed, and more information can be found on the Defense SBIR/STTR website.

Description

OUSD (R&E) CRITICAL TECHNOLOGY AREA(S): Sustainment

 

The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and import of defense-related material and services, including export of sensitive technical data, or the Export Administration Regulation (EAR), 15 CFR Parts 730-774, which controls dual use items. Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with the Announcement. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws.

 

OBJECTIVE: Develop a high-temperature, high-efficiency ES/G and a system generator control unit (GCU), with the goal of optimizing heat load, output power, size, and/or weight of future power systems.

 

DESCRIPTION: The Navy is interested in pursuing new Electrical Power Generating System (EPGS) technologies for increasing efficiency, specific power, power density, and power capacity for 270 Vdc More-Electric Aircraft (MEA) systems. The EPGS is the main power source for MEA and the solution should provide motoring for main engine start capabilities. Improvements to the existing EPSG, or a new novel power generation system architecture/design, will be considered.

 

A 200-kW EPGS that converts rotational shaft power to 270 V is of interest. The generator should be able to produce this voltage and power across at 1.00-to-1.75 speed range—with the higher region of the speed range around 24,000 rpm. The generator should be capable of proving a stable power source for continuous and intermittent power across the operating speed range. It should be able to source stable electrical power into high step-load Constant-Power Loads (CPL) commensurate with MIL-PRF-22140B. The EPGS should also be able to maintain typical MIL-STD-704F power quality metrics while considering relevant line impedances for generating into the dynamic CPLs.

 

The offeror should show feasibility of the benefits and performance capability during Phase I using modeling, simulation, and analysis of the electromagnetic, thermal, rotor dynamics, reliability, fault conditions, etc. Careful consideration should be made that this is a mission-critical component for most MEA systems. The analysis should be provided for both steady-state and transient conditions.

 

The Navy requires new technologies to increase the efficiency and power capacity of today’s EPGS. The electrical starter/generator (ES/G) (ES/G) is the main power source for a MEA systems, providing motoring and main engine start capabilities for the aircraft. Improvements to the existing EPGS, or a new novel power-generation system architecture/design, will be considered. This effort should focus on providing an ES/G system to provide a minimum generator power output of: 200 kW (continuous), 250 kW (2-minute overload), 300-500 kW (5-second overload), and > 500 kW (0.5-second overload). The power generation operating range should be able to generate 270 Vdc and power across a 1.00 to 1.75 speed range (with peak speeds at roughly 24,000 rpm).

 

Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by 32 U.S.C. § 2004.20 et seq., National Industrial Security Program Executive Agent and Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA) formerly Defense Security Service (DSS). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances. This will allow contractor personnel to perform on advanced phases of this project as set forth by DCSA and NAVAIR in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material during the advanced phases of this contract IAW the National Industrial Security Program Operating Manual (NISPOM), which can be found at Title 32, Part 2004.20 of the Code of Federal Regulations.

PHASE I: Define generator design approach and develop an implementation plan. Validate approach analytically or provide test data or bench top hardware that would validate approach. Ensure maximum use of computer modeling and simulation techniques in this phase. Demonstrate a thorough working knowledge of applicable military standards. The Phase I effort will include prototype plans to be developed under Phase II.

 

PHASE II: Develop and demonstrate generator technology that can provide 200 kW of continuous power that can be fitted into the aircraft. Ensure that the generator package includes a GCU that is capable of controlling generator functionality. The package will be subjected to proof-of-concept testing at full qualification levels.

 

Work in Phase II may become classified. Please see note in Description paragraph.

 

PHASE III DUAL USE APPLICATIONS: Package and integrate new generator for use in the aircraft. Provide unit(s) to be subjected to full qualification testing and flight test profiles. The notable benefits include the increased efficiency and power capacity of the ES/G, reduction of system volume and weight, and interconnected complexity. It will improve thermal performance over the current system while also providing better engine and air vehicle performance. It will significantly reduce engine heat loads throughout the mission while focusing on heat rejection impacting the ES/G.

 

Specific industries, such as the automotive, marine, industrial machinery, agricultural machinery, and construction machinery, could benefit from this innovative ES/G technology. All of the above would provide significant benefits to both military and commercial aircraft applications.
