Dong Fang Hong
Dongfanghong () was a satellite program of the People's Republic of China. The program started in August 1965 as Project 651—a less ambitious successor to the earlier Project 581—with the goal of launching a satellite heavier than both Sputnik 1 and Explorer 1 into space, and developing all the necessary technologies to do so. History In 1958, the Chinese Academy of Science proposed Project 581 which included a plan to launch a satellite into space before 1 October 1959. The project was troubled due to the country's lack of expertise in the field of rocketry. On 21 January 1959, Zhang Jingfu, who was in charge in the satellite research program, postponed the project to allow effort to be put into developing more basic technologies, such as sounding rocketry. In December 1964, during the 3rd National People's Congress, Zhao Jiuzhang suggested that the work on satellites be resumed. In August 1968, the Central Special Committee approved Chinese Academy of Science's plan, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dong Fang Hong I
''Dong Fang Hong 1'' (), in the western world also known as China 1 or PRC 1, was the first space satellite of the People's Republic of China (PRC), launched successfully on 24 April 1970 as part of the PRC's Dongfanghong space satellite program. It was a part of the "Two Bombs, One Satellite" program. At , it was heavier than the first satellites of other countries. The satellite carried a radio transmitter which broadcast the ''de facto'' national anthem of the same name. The broadcast lasted for 20 days while in orbit. It was developed under the direction of Qian Xuesen, dean of the China Academy of Space Technology (CAST). At the time, a total of five identical satellites were created. The first satellite launched successfully. The academy formulated a "Three-Satellite Plan" consisting of ''Dongfanghong 1'', re-entry satellites, and geosynchronous orbit communications satellites. Sun Jiadong was responsible for the ''Dongfanghong 1'' technology. In 1967, Dang Hongxin chos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dong Fang Hong 02
Dong Fang Hong 2 (also romanised as Dongfanghong 2) was the primary television satellite used by China during the later part of the 20th century. It was developed at the Chinese Academy of Space Technology (CAST) and had a design life 4.5 years. The first operational satellite in this group was launched into a geosynchronous orbit on 8 April 1984. Three satellites orbited in geosynchronous orbits at 87.5°, 110.5°, and 98.0° east. A fourth satellite failed to achieve a stable orbit due to a problem with the third stage. Background Operating under the name Dong Fang Hong 2, the Shiyong Tongbu Tongxing Weixing (STTW, , literally Operational Geostationary Communications Satellite) was the designation of a family of indigenous Chinese communications satellites developed under the Project 331 initiative of the late 1970s and early 1980s. Being able to provide both civilian and military long distance telephony, in addition to satellite television, the initiative was promoted by t ...

China Railways DFH Shunting Locomotives
The China Railways "Dongfang Hong" diesel-hydraulic locomotive classes DFH2, DFH5, DFH6 and DFH7 built from the 1970s to 1990s were all used as shunters on the Chinese railway network. The use of diesel-hydraulic shunters has fallen out of favour on the Chinese rail network, with diesel-electric locomotives being used, however diesel-hydraulic machines continued to be produced for industrial railways - mainly the China Railways GK classes.DFH5 东方红5 , ''www.railwaysofchina.com'' The DFH21 class is a version of the DFH2, and was used on the Yunnan–Vietnam Railway for both passenger and freight services; the same machines are used on the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Railways DFH Mainline Locomotives
The China Railways DFH1 was a type of 4-axle B'B' single-cab diesel-hydraulic locomotive used on mainline passenger services; the DFH3 was a later development of a similar design but with two driving cabs. The China Railways DFH4 was a 6-axle high-powered freight and passenger locomotive, it did not reach mass production. China Railways DFH1 The first prototype unit (NY1) (''neiran yeli chuandong'' meaning diesel-hydraulic transmission) was produced in 1959 at Sifang locomotive works, and given the name 'Weixing'. Locomotive design was similar to German diesel-hydraulic machines such as the DB Class V 200 - the machine had a pair of high-speed diesel engines, each driving a separate hydraulic torque converter based transmission resulting in low mass compared to contemporary diesel-electric machines. Series production began in 1964. The locomotive was used for passenger trains. The locomotives could be worked in multiple, and were often used in this way, with a cab at each end. ...
