PC Krause and Associates Inc. (PCKA) was contracted to conduct analysis and modeling with the goal of developing an end-to-end simulation of a team developed example more-electric aircraft. Although the team assembled and the goal of the program were appropriate, NASA Headquarters reduced the funding soon after the start of the effort followed by a three month work stoppage and soon after, the program was discontinued.

Type of Award: SBIR Phase III, CPFF (In response to BAA) Lead-In Phase II: N61533-89-C-0062 Contract Number: F33615-93-C-2361 Subcontractors: Purdue and Northrop Agency: U.S. Air Force Research Laboratory Status: Completed Period: 9/30/93 to 2/19/01 Principal Investigator: Paul Krause Brief Description and Purpose: PCKA and the Aircraft Division of Northrop Corporation teamed to develop and validate component simulations applicable to the More Electric Aircraft (MEA) concept. The overall goal was to provide the Air Force and the aircraft industry with computer simulation support and in-house simulation capability so that MEA power systems would be investigated before, during, and after construction. To achieve this goal, it is proposed to develop detailed hybrid and detailed digital as well as reduced-order computer models of the main components of the MADMEL system. The component simulations were modular and generic in nature so that the models could be used to simulate these components with different ratings and in different system arrangements. Final Report: MEA Electrical System Modeling, Simulation, and Performance Analysis This report is 230 pages in length wherein detailed and reduced order models of the MADMEL components are developed. The components include (1) synchronous machine, (2) switched reluctance generator, (3) PWM inverter fed induction motor, (4) electro-hydrostatic actuator, and (5) MADMEL electrical load simulator.

The approach of concurrent design and development (concurrent engineering) was emphasized. Since accurate computer simulation could be used advantageously in all stages of component and system design and development, simulation becomes a necessity if this type of engineering approach is to succeed. Since 1987, PC Krause and Associates (PCKA) had been involved in the development of computer models for the Navy (NSWC). The computer models which were being used by NSWC to design and investigate Navy related power systems were developed and originally coded in ASCL by PCKA. The need for simulation in the Navy’s concurrent engineering approach to the Advanced Surface Machinery Programs was made very apparent at the Industry Brief. Coupling this with the fact that (PCKA) was instrumental in developing the simulation capability of NSWC provided the impetus for this contract. PCKA had not become involved with the manufacturers other than through or with the Government agency. This enabled PCKA to provide an independent evaluation. As a result of this independence and the fact that PCKA had an excellent working relationship with industry allowed PCKA to play its first role as an honest broker.

Period: 6/30/94 to 6/30/99 Principal Investigator: Paul Krause Brief Description and Purpose: It became clear that computer simulation would play a major role in the Navy’s Advanced Surface Machinery and the Advanced Electrical Power System programs at CDNSWC. In particular, accurate computer simulations could be used advantageously in all stages of component and system design and development. Simulation is a necessity if concurrent design and development (concurrent engineering) is to succeed. Since 1987, P C. Krause and Associates (PCKA) had been involved in the development of computer models for the Navy (NSWC). The need for simulation in the Navy’s engineering approach to advanced machinery and electrical systems coupled with the fact that PCKA had been instrumental in developing the present simulation capability of NSWC provided the basis for this contract. PCKA provided the Navy with engineering services in the area of detailed and reduced-order modeling and analysis of components/systems which were being contemplated and/or developed in the advanced machinery and electrical systems programs. Since PCKA had not been involved with manufacturers other than through or with the Government agency. This enables PCKA to provide an independent evaluation since the personnel associated with PCKA had not received corporate grants or contracts from manufacturers which could be construed as a conflict of interest. Here, again, PCKA was successfully casted in the role of an honest broker.

Period: 9/30/99 to 9/11/01 Principal Investigator: Paul Krause Brief Description and Purpose: In the mid to late 1990’s, PC Krause and Associates (PCKA), Purdue University, the University of Missouri-Rolla (UMR), and the University of Wisconsin-Milwaukee (UWM) had been extensively involved, as a group, in research, analysis, simulation, and design of power-electronic based systems for government agencies (Navy, Air Force, NASA, and the Army) interested in the more-electric initiative program. This group, of which PCKA was the small business arm, evolved naturally from a need to combine expertise in order to conduct the required work which has involved a large spectrum of power/drive systems ranging from spacecraft to tactical vehicles. The commonalities that exist between these many systems in configuration and components became very apparent. This sole-source contract was the first effort by the Navy to encourage interagency interaction in sharing the results of the research and engineering projects common to shipboard power systems and to provide a convenient funding vehicle to encourage shared funding, among these agencies, for projects of mutual interest. Clearly, this is in keeping with the emphasis on interaction and consolidation of government-funded programs. This contract was one of the first steps toward the goal of establishing an inter-agency funded group made up of universities, government agencies (laboratories), and industry and focused on the research, analysis, design, and development of electric power systems.
