The Agency of Industrial Science and Technology (AIST), MITI of Japan, started research and development on a super/hypersonic transport propulsion system in FY1989 as an eight year project. The project, forecasting a flight cruise capability of up to Mach 5, aims at establishing basic technologies for an engine that combines a ramjet engine and a high performance turbojet engine. This paper presents the background, objective, organization, contents, etc., of this national project.

The outline of plans for the research and development of an advanced reheat gas turbine under the Moonlight Project (Agency of Industrial Science and Technology, Ministry of International Trade and Industry) has already been announced in 1981 at Houston (81-GT-28), while technical problems related to the pilot plant (Paper No. 83-TOKYO-IGTC-117) as well as performance and characteristics (Paper No. 83-TOKYO-IGTC-40) have been announced at the 1983 Tokyo International Gas Turbine Congress. No-load shop tests conducted on the pilot reheat gas turbine during the period of May to July, 1983, were consummated with highly satisfactory results, so this paper is dedicated primarily to giving a description of the shop tests.

In the current four-year term project in Japan, new platform science and technology is proposed as a core concept of research and development of advanced magnesium alloys together with understanding of their intrinsic characteristics. The research fields related to advanced super-light magnesium alloys for 21st Century have been focused to the selected three categories; ecomaterial design and processing, high qualification of mechanical performance, and high performance design and processing in functionality. On the basis of the obtained results, platform science and technology for environmentally benign and high performance magnesium alloys is constructed as an industrial base material for the next generation. As a result, numerous large-scale joint research and development projects on magnesium alloys based on partnerships between industries, academia and government has already started towards practical utilization since last year.

<p class="Abstract">An inter-laboratory comparison of the calibration capability for torque measuring devices (TMDs) was conducted between the National Metrology Institute of Japan (NMIJ) in the National Institute of Advanced Industrial Science and Technology (AIST) and the Korea Research Institute of Standards and Science (KRISS). Three high-performance torque transducers having rated capacities of 100 N·m, 1 kN·m, and 2 kN·m, and a bridge calibration unit (BN100A) were used as the transfer devices. The 1 kN·m and 2 kN·m transducers had one bridge, but the 100 N·m transducer had two bridges that acquired data more reliably. An identical indicator/amplifier type (DMP40) owned by each laboratory was used. All of the transducers and BN100A were transferred from NMIJ to KRISS. For the comparison, NMIJ used 1 kN·m and 20 kN·m deadweight torque standard machines (TSMs), and KRISS used a 2 kN·m deadweight TSM. In particular, the capability of the 1 kN·m TSM at NMIJ was examined after some improvements. In the calibration range from 50 N·m to 2 kN·m, relative deviations were less than 3.0 × 10<sup>-5</sup> for increasing torques. Sufficiently small deviations were obtained between the calibration results in the two laboratories, as compared with their calibration and measurement capabilities (CMCs), which were 3.5 × 10<sup>-5</sup> for the 1 kN·m TSM at NMIJ, 7.0 × 10<sup>-5</sup> for the 20 kN·m TSM at NMIJ, and 5.0 × 10<sup>-5</sup> for the 2 kN·m TSM at KRISS (as relative expanded uncertainties).</p><p class="Abstract"> </p>

This two-part article introduces a novel hybrid propulsion system based on the DEA compressor. The system encompasses a Pulse Detonation TurboDEA as the master engine that supplies several full-electric ancillary thrusters called DEAThruster. The system, called the propulsion set, can be categorized as a distributed propulsion system based on the design mission and number of ancillary thrusters. Part A of this article explains the design process comprising intake, compressor, detonation process, diffuser, axial turbine, and the exit nozzle. The main target is to design a high-performance low emission propulsion system capable of serving in a wide range of altitudes and flight Mach numbers that covers altitudes up to 20,000 m and flight Mach number up to the hypersonic edge. Designing the propulsion set, the design point is considered at the static condition in the sea level. Design results show the propulsion set can satisfy all requirements necessary for its mission.
