PROPULSION CAPABILITES SUMMARY
Performance Software has considerable experience and knowledge specific to Aerospace Propulsion systems software development from small auxiliary power units (APU) to large commercial engines currently in service with airlines. Our personnel also have experience integrating highly regulated avionics platforms with DEEC and FADEC systems governed by the DO-178B certification standards and their supporting simulation environments. Activities include full-cycle software development ranging from system-level requirements development through Formal Verification and Certification Support.
Performance Software has developed a solid FADEC/DEEC engine control systems knowledge base while supporting many programs working with various customers. PSC successfully managed its resources to satisfy critical customer milestones on several full software life cycle development efforts that focused on the diverse product lines across the Air Transport and Business and Commuter Aviation markets. The following are samples of Aerospace platforms that have been supported:
- F124-GA-200 Engine FADEC for Aermacchi M-346
- LV100 Engine for XM2001 Self-Propelled Crusader 155 mm Howitzer
- TPE331-10 Turboprop DEEC for Predator B UAV
- Honeywell AS900 FADEC for Regional Jet Engines
The Honeywell F124-GA-200 engine equipped with a new Full Authority Digital Electronic Control (FADEC) based on its Modular Aerospace Control (MAC) platform was developed for use in Aermacchi's M-346 advanced trainer. The F124 MAC based FADEC is scalable, adaptable, fault-tolerant and uses a Time Triggered Protocol (TTP) for inter-module communication. Honeywell's dual channel FADEC design for the M-346 was among the first aerospace uses of a time-triggered protocol (TTP) bus. Development focused on increased data flow and redundancy management as compared to traditional dual channel electronic engine controls.
The LV100 was a two-spool, axial-centrifugal-flow free-turbine aero-derivative industrial gas turbine machine developed by Honeywell International as a vehicular powerplant/engine. The development of the LV100 engine was initially sponsored by the US Department of Defense through the US Army Tank, Automotive and Armaments Command, under the Advanced Integrated Propulsion System (AIPS) effort. LV100 was chosen as the powerplant for the XM2001 Self-Propelled Crusader 155 mm Howitzer and the XM2002 Self-Propelled Crusader Resupply Vehicle. (Program was canceled in 2002 by Sec Def) The LV100 developed in excess of 1,500 shp (1,118 kW).
The TPE331-10 Turboprop engine was developed for the next generation for the Predator B Unmanned Air Vehicle (UAV). The Digital Electronic Engine Control (DEEC) provided improved power management and increased loiter time for the aircraft. The Predator B aircraft was designed as a long-endurance, high-altitude, multi-mission system for a variety of government and military customers, including the United States Air Force, the Department of Homeland Security, NASA and the United States Navy. The Honeywell TPE331-10 produces 900 shaft horsepower with best in class fuel consumption.
The AS900 Full Authority Digital Electronic Controller (FADEC) is manufactured by Honeywell International, Inc. The unit is a long field life (20 years), low volume (~3200 units), long manufacturing life (5-6 years), safety critical component used in engines for regional jets.
Performance Software has supported several Avionics Displays development efforts with key customers where Performance Software successfully scoped and managed its internal resources to meet critical customer milestones. Work packages included software lifecycle development of the AIMS Display for the Boeing 777, Graphical Generation Function (GGF) Applications for the EPIC platform utilized across multiple business jet platforms. Each of these display programs required integration and interpretation of pertinent DEEC/FADEC I/O data utilized by the avionics platform.
