Assessment of Aerospace Technology in Japan Viewed from an American Perspective

1991-09-01
911968
This is an assessment of Aerospace Technology in Japan, the national vision supporting it and the strategy underlies it's ultimate purpose. It includes a comparison of the organizations and missions of the two principle aerospace agencies: One, the Institute of Space and Astronautical Science (ISAS); and, two, the National Space Development Agency (NASDA). Included are the launch capabilities and deep space facilities of ISAS, at Kagoshima Space Center (KSC) in Uchinoura on Kyushu island; and the NASDA Tanegashima Space Center (TSC) on Tanegashima Island. Also included are the design and development history of domestic Nippon launch and space vehicles, beginning with the licensing of the United States Thor-Delta rocket technology and including the design of the domestic H-I second and third stages and the all domestic H-II vehicles.

Structural Ceramics in Automotive Engines-Integration of Design, Development and Manufacturing Procedures

1990-02-01
900400
This is a descriptive review of the ceramics structural applications developed by Isuzu, Mazda, Nissan, Toyota and General Motors in spark ignition, Diesel and gas turbine automotive engines; new analytical procedures needed for the design of structural ceramics; new silicon nitride ceramics with strength of material properties approaching steel; new ceramics processing techniques which have been reduced to commercial practice in Japan on a mass production scale; and tests of vital structural components fabricated of these ceramics.

HSST Magnetic Levitation Trains: Past, Present and Future

1990-08-01
901481
This is an assessment of Japanese High Speed Surface Transit (HSST) policy, vision, goals, and magnetic levitation development and commercialization technology. It includes an illustrated historical review of past HSST magnetic levitation vehicle developments, a review of the present status of HSST trains, and an outline of future HSST conventional magnetic levitation trains with speeds of 300 km/h for interurban and transcontinental service. Also described are: the start of construction of a new test track which includes the track switching mechanism designed for the Las Vegas HSST route in the United States; test operation execution for the practicalization of HSST-100 by the newly formed Chubu (Central Japan) HSST Development Corporation of Nagoya Railroad Company and HSST Corporation. These magnetic levitation electric trains have been under development since 1974 and are now considered ready for introduction into commercial service.

A National Vision for MagLev Transit in America

1990-08-01
901482
This is an assessment of United States High Speed Guided Transit (HSGT) systems policy, vision, goals, and magnetic levitation development and commercialization technology. It includes a historical review of past magnetic levitation vehicle developments, a review of the present status of MagLev trains, and an outline of future conventional (EML) Electro Magnetic Levitation for speeds under 400 km/h; and, (SC) Super Conductive (EDL) Electro Dynamic Levitation for subsonic speeds approaching 900 km/h. Magnetic levitation transit technology has been under development in America since the United States Congress passed the 1965 High Speed Guided Transit Act (HSGT) which authorized the Department of Transportation to fund HSGT projects. Since this initial effort focused attention on the potential of the magnetic levitation concept for very high speed transit applications, this technology has been an ongoing development in Europe and Japan.

Automotive Propulsion Technology for the 1990's

1992-02-01
920573
This is an assessment of alternative propulsion technology options presently under investigation for potential application to automobile propulsion in the 1990's. It includes a brief review of key aspects of the new US DOE National Energy Strategy, as recommended to the President in March 1991, and the impact on future automotive propulsion policy choices in the immediate future. Also considered is the impact of the decision by the California Legislature, in the 1990-91 State Budget, which directed the Department of Transportation (Caltrans) to expand the assessment and policy support for improvements in transportation technology. In addition, key technical aspects of the prime mover options currently under development around the World are shown. Among these options are: ceramic piston engine dynamic structural components for conventional four-stroke engines, ceramic gas turbines, new two-stroke engines, and electric propulsion.
