Investigation and Design of a High Efficiency Turbine Wheel

摘要

The objective of this task was to design a new turbine wheel to improve the reliability of the 36E144 Air Turbine Starter to be used on the LAMPS SH-60B helicopter. The program concentrated on strengthening and improving the turbine blade configuration. A stress analysis was conducted to determine the blading characteristics at severe operating conditions. An improved turbine wheel, P/N 2499860 was designed, fabricated, and exposed to a 2000 cycle starter qualification test at NAPC. When inspected after the test, the turbine was in excellent condition and completely free of any defects or distress. The task objective to design and build a more reliable system was achieved. The efficiency level of the new turbine wheel design met Navy requirements.
