Advanced Engine Control Program
Abstract
The report describes the results of a 12-month program to continue development of electronic control and centrifugal pump technology for use in future small (2- to 5-lb-per-second airflow) turboshaft engines. Redesign of the electronic computer using micropowered analog and digital components has resulted in a reduction in electrical power dissipation from 60 to about 7 watts, which virtually eliminates self-heating problems. Supply voltage and noise sensitivities have also been substantially reduced. The induced vibration has been limited to less than 30 g's over the complete vibration spectrum specified in MIL-E-5007C. Increasing the pump speed from 37,500 to 55,000 rpm to reduce disc friction has resulted in a 50% reduction in the fuel temperature rise.
