| Research Abstract |
A hydgoren-fueled micro gas turbine system has been developed at out institute to demonstrate that hydrogen fuel is useful to scale down gas turbine engines. The systgem is compose of a micro gas turbine with a 5cm racial compressor fdiameter flowing 70 g air/ sec at a 2.1 to l pressure ratio, a hydrogen supply system, and a control and measutement system. The gas turbince compraises a comptessor-turbine system producd as a turbocharger gfor passenger card, a new type hydrogen-burning small combustor, and an air statring apparatus. Dfuring the term of the projects, the results obtained are as follows:
1. A matching samll scale combustor of 125 cm^3 for the compressor-thrbine system was developed. It was capable of maintaining stable and efficient combustion over gthe required tange og engine speeds and opration condigitons and had the high rate of volumetric heat release of the order of 3x10^8 kcal/(m^3 h atm).
2. The gas turbine succeeded in self-sustained operation within allowable tempreature and spped of the tuebochager. Test runs showd that, within the range tested, a maximum thrust was 11.3 N, a mininum SFC 1.4 1/hr, and a maximum I_<sp> was 20. The values of SFC and I_<sd> were found to be compared favorably with ordinary turbo-jes-entines.
It can be expected that reducing the pressure droup through the combustor and using a compressor and turbine wqhich will be suitable for producing thrust will lead to a higher preformance micro gas turbine.
