The control system for aero-propulsion engines is one of the most successful, if underrated, components of the turbine engine system. Although the mechanical turbine components provide the power for flight, the control system enables the engine to achieve unprecedented safety and efficiency. And, while the vast majority of research investment is directed to the development of turbine components, overall system performance is ultimately determined by the function of controls. The success of engine controls is remarkable given that its capability is an indirect result of massive private investment, on the order of hundreds of millions of dollars per year, in the totally unrelated area of consumer electronics. In reality, the turbine engine has been a beneficiary of the success of the popular culture at large. Unfortunately, the continued progress in propulsion system performance is also creating a divergence between the unique needs for engine controls and the direction of electronics technology.

Author Name (s): William .D. Ivancic, Obed S. Sands, Casey J. Bakula, Daniel R. Oldham, Ted Wright, Martin A. Bradish, Joseph M. Klebau Mailing Address: Martin Bradish, NASA Glenn Research Center, 21000 Brookpark Road, MS 86-5, Cleveland, Ohio 44135 USA Telephone Number: (216) 433-3848 Fax Number: (216) 433-6382 eMail Address: martin.a.bradish@nasa.gov This paper summarizes the Power, Avionics and Software (PAS) 1.0 subsystem integration testing and test results that occurred in August and September of 2013. This paper covers the capabilities of each PAS assembly to meet integration test objectives for non-safety critical, non-flight, non-human-rated hardware and software development. This test report is the outcome of the first integration of the PAS subsystem and is meant to provide data for subsequent designs, development and testing of the future PAS subsystems. The two main objectives were to assess the ability of the PAS assemblies’ to exchange messages and to perform audio tests of both inbound and outbound channels.

As the US is getting ready for the Next Generation (NextGen) of Air Traffic System, there is a growing concern that the current techniques for verification and validation will not be adequate for the changes to come. The JPDO (in charge of implementing NextGen) has given NASA a mandate to address the problem and it resulted in the formulation of the V&V of Flight-Critical Systems effort. This research effort is divided into four themes: argument-based safety assurance, distributed systems, authority and autonomy, and, software intensive systems. This paper presents an overview of the technologies that will address the problem.
