NASA's Ames-Dryden Flight Research Facility in Edwards, California, modified an F-15 jet engine to increase its thrust by 10 percent and fuel savings by 5 to 7 percent. The modification grew out of NASA's Highly Integrated Digital Electronic Control program (HIDEC), which lessened unneeded engine stall margins (the amount that engine operating pressure must be reduced to avoid stall). The typical 25 percent stall margin allows for a contingency of any of the worst flight conditions and robs 15 percent of an engine's usable power. The HIDEC created engine and flight control systems that communicate with each other; thus the engine adjusts itself according to actual flight, not assumed constants. (NASA Release 86-176)
General Samuel Phillips presented the Report of the NASA Management Study Group, for which he was Project Director, to Administrator Dr. James C. Fletcher. The report conducted an assessment of NASA practices in long-range and strategic planning, managing NASA programs, human resources and procurement, maintaining budget, financial and program control, and dealing with external affairs. The report went on to assess the effectiveness of NASA's organization and to make recommendations to improve agency practices and organization. (Report of the NASA Management Study Group, Dec 16/86)
