GRAPHITE TURBINE FEASIBILITY PROGRAM.
Abstract
The objective of the program is to analyze and select an optimum fiber reinforced graphite composite for turbine disk and blade construction; to develop reliable fabrication methods, and to demonstrate the performance potential, with the aid of a high speed dynamometer, of lightweight, high temperature, high speed and high efficiency graphite turbines. A fiber reinforced layup scheme for a graphite wheel was specially developed and appears to be feasible. Six wheels are to be tested within a test plan which includes two cold burst tests, one hot gas burst test, one five minute hot gas endurance test and one hot gas performance test. The hot gas will be at a temperature of 4500F. Special test equipment was designed and is being fabricated to support the graphite turbine feasibility program. This equipment includes a special high temperature gas generator injector for the CTF-hydrazine propellants, a water cooled tungsten nozzle, a high speed homopolar inductor alternator dynamometer, and an air ejector system capable of producing the required reduced exhaust pressure for turbine performance objectives.
