This valve can generate an intermittent flow by using gas enthalpy, so no power source or control unit is\nnecessary. The mass flow per valve unit mass is comparatively large, the thrust change with changing supply pressure\nis very responsive, and the inflow supply pressure range for stable operation is wide. In a mass flow rate measurement\nexperiment using a single-piston inflow-driven valve, the operation frequency and mass flow rate were predictable. In\na thrust measurement experiment with a pulse detonation rocket engine using a three-piston inflow-driven valve, the\npulse detonation engine\u2019s stable operation over a wide range of supply pressure was confirmed and the timeaveraged\nthrust was measured. Themaximum time-averaged thrust of 22.6Nwas achieved at a fuel (ethylene) supply\npressure of 0.95MPaand an oxygen supply pressure of 1.9 MPa. Themaximum specific impulse of 279 s was achieved\nat an ethylene supply pressure of 0.8 MPa and an oxygen supply pressure of 1.6 MPa.", "subitem_description_type": "Abstract"}]}, "item_5_identifier_34": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2241/116682"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Aeronautics and Astronautics"}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.2514/1.47421", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2011 by the University of Tsukuba.
