National Aerospace Laboratory Of Japan
The National Aerospace Laboratory of Japan (NAL) was established in July 1955. Originally known as the National Aeronautical Laboratory, it assumed its present name with the addition of the Aerospace Division in 1963. Since its establishment, it has pursued research on aircraft, rockets, and other aeronautical transportation systems, as well as peripheral technology. NAL was involved in the development of the autonomous ALFLEX aircraft and the cancelled HOPE-X spaceplane. NAL has also endeavored to develop and enhance large-scale test facilities and make them available for use by related organizations, with the aim of improving test technology in these facilities. The NAL began using computers to process data since the 1960s. It began working to develop supercomputer and numerical simulation technologies in order to execute full-scale numeric simulations. The NAL, in collaboration with Fujitsu, developed the Numerical Wind Tunnel parallel supercomputer system, which went into opera ...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ALFLEX
ALFLEX (Automatic Landing Flight EXperiment) was an experimental unmanned aircraft created by NASDA and NAL, the predecessors of JAXA, in 1996. It was built as a successor to HYFLEX as part of the HOPE program. ALFLEX was built to establish the basic technology of automatic landing. The design featured a streamlined metal hull, delta planiform wings, and large winglets. Despite being a project of Japanese aerospace agencies, ALFLEX never left the atmosphere. Instead, it was carried up to a high altitude by a helicopter, then released to automatically glide down to the designated landing site, navigating by means of onboard computers. ALFLEX completed thirteen drop tests from July to August 1996, all of which were successful. Specifications (ALFLEX) * Length (without pitot boom): 6.10 m * Wingspan: 3.78 m * Height (without gear): 1.35 m See also * HOPE-X * HYFLEX * OREX OREX (Orbital Re-entry Experiment) was a NASDA re-entry demonstrator prototype which was launched in 19 ...

HOPE-X
HOPE (H-II Orbiting Plane) was a Japanese experimental spaceplane project designed by a partnership between NASDA and NAL (both now part of JAXA), started in the 1980s. It was positioned for most of its lifetime as one of the main Japanese contributions to the International Space Station, the other being the Japanese Experiment Module. The project was eventually cancelled in 2003, by which point test flights of a sub-scale testbed had flown successfully. History The original HOPE project called for the building of a sub-scale orbital prototype known as HOPE-X, for H-II Orbiting Plane, Experimental. This would be used for flight testing and systems validation, before moving onto the larger HOPE, which used many of the same parts and general design in a 4-man design. As the name implies, both would be launched on Japan's new H-2 launcher, the full-scale HOPE requiring substantial upgrades in performance. At the time, Japan was an up-and-coming industrial powerhouse, and their spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Institute Of Space And Astronautical Science
(ISAS) is a Japanese national research organization of astrophysics using rockets, astronomical satellites and interplanetary probes which played a major role in Japan's space development. Since 2003, it is a division of Japan Aerospace Exploration Agency (JAXA). History The ISAS originated as part of the Institute of Industrial Science of the University of Tokyo, where Hideo Itokawa experimented with miniature solid-fuel rockets ( Pencil Rocket and Baby Rocket) in the 1950s. This experimentation eventually led to the development of the Κ (''Kappa'') sounding rocket, which was used for observations during the International Geophysical Year (IGY). By 1960, the Κ-8 rocket had reached an altitude of 200 km. In 1964, the rocket group and the ''Institute of Aeronautics'', along with scientific ballooning team, were merged to form within the University of Tokyo. The rocket evolved into the L (''Lambda'') series, and, in 1970, L-4S-5 was launched as Japan's firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Space Development Agency
The , or NASDA, was a Japanese national space agency established on October 1, 1969 under the National Space Development Agency Law only for peaceful purposes. Based on the Space Development Program enacted by the Minister of Education, Culture, Sports, Science and Technology (MEXT), NASDA was responsible for developing satellites and launch vehicles as well as launching and tracking them. The first launch vehicles of NASDA (N-I, N-II, and H-I) were partially based on licensed technology from the United States, particularly the Delta rocket family. The H-II was the first liquid fuel rocket to be fully developed in Japan. Hideo Shima, chief engineer of the original Shinkansen "bullet train" project, served as Chief of NASDA from 1969 to 1977. On October 1, 2003, NASDA merged with the Institute of Space and Astronautical Science (ISAS) and the National Aerospace Laboratory of Japan (NAL) into one Independent Administrative Institution: the Japan Aerospace Exploration Agency (J ...

Independent Administrative Institution
An Incorporated Administrative Agency (独立行政法人, ''Dokuritsu gyōsei hōjin'' or ''Dokugyo'' in abbreviation) is a type of legal corporation formulated by the Government of Japan under the Act on General Rules for Incorporated Administrative Agencies (Act no. 103 of 1999, revised in 2014). The independent agencies are not under the National Government Organization Act that provides for the ministries and agencies of Japan. Originally proposed by the Administrative Reform Council, the independent agencies are created based on the concept of separating the ministries and agencies of the government into planning functions and operation functions. Planning functions remain within government-based ministries and agencies while operating functions are transferred to the independent agencies. Incorporated Administrative Agencies utilize management methods of private-sector corporations and are given considerable autonomy in their operations and how to use their given budgets. I ...
