It's refreshing to see a truly indigenous rocket program. Unlike the South Korean and Indian rocket programs that are based on Russian engines, technologies, or Russian scientists/advisers/consultants, Taiwan's hybrid rocket technology is 100% indigenous.

An interdisciplinary team from Taiwan's National Cheng Kung University successfully launched two small rockets at a testing ground near Tainan City in the south of the country, scoring breakthroughs in GPS technology and multistage rocket decoupling, NCKU announced March 25.

The team, led by professor Juang Jyh-ching of Tainan City-based NCKU's Department of Electrical Engineering and supported by the rocket and satellite program of the ROC Ministry of Science and Technology, launched and recovered two small hybrid rockets March 20 at Shalun Farm in the city. Following the success, the team said it will attempt to launch a 1,000-kilogram rocket to a height of 30 kilometers in May.

Many countries are currently researching hybrid rockets because of their low cost, greater safety and environmental friendliness, NCKU said. The university's Aerospace Science and Technology Research Center and Department of Aeronautics and Astronautics have already had notable successes in developing this field.

GPS systems are a critical component for accurately targeted rocket launch. Rockets are subject to extreme G-force as they accelerate, and GPS receivers commercially available in the market cannot be used on the rockets.

The team used a high dynamic GPS receiver it developed that can withstand G-forces of more than 10 G's and properly track Doppler frequency shift during the launch.

Stage decoupling is a crucial process for any multistage rocket, with extremely reliable mechanisms a prerequisite, as later stages can only fire once expended fuel tanks have been jettisoned. The NCKU team successfully employed a V-shaped release mechanism.


According to Juang, successful recovery of the rockets enables a full record of flight details to be retrieved. A high-altitude balloon was also released before the launch to obtain prevailing atmospheric temperature and wind conditions for use in subsequent analysis of the launch.

More than 50 people participated in the launches. (SDH)"

It would not have been possible for India to make such significant forays into space without the tremendous support and cooperation extended by Russian scientists over the decades."

US rocket technology is based on German technology.no it is developed by germans.
Did you really have to fully quote an almost full page post to make your niggling remark?

And google Robert Goddard.

read this.


those wer used in india when you were busy killing and mass murdering native americans.:wave:
I know about Mysorean rockets. I know about Congreve.

And I know that more Indians have died at the hands of other Indians since 1952 than all the members of native North American tribes since 1492 killed by each other or by Europeans..

I know you can throw endless shit up on DFI until Hell freezes over, but you continue to contribute nothing here.

Maybe you can grow up and give it a rest. Try posting on topic one time.

whatz the point u want to make?
u are talking as if USA invented rockets.
Nothing will penetrate your hopeless ignorance, but I offer this for interest of others.

Dr. Robert H. Goddard, American Rocketry Pioneer | NASA
Dr. Robert Hutchings Goddard is considered the father of modern rocket propulsion. A physicist of great insight, Goddard also had a unique genius for invention. It is in memory of this brilliant scientist that NASA's Goddard Space Flight Center in Greenbelt, Md., was established on May 1, 1959.

By 1926, Goddard had constructed and successfully tested the first rocket using liquid fuel. Indeed, the flight of Goddard's rocket on March 16, 1926, at Auburn, Mass., was as significant to history as that of the Wright brothers at Kitty Hawk.

Primitive in their day as the achievement of the Wrights, Goddard's rockets made little impression on government officials. Only through modest subsidies from the Smithsonian Institution and the Daniel Guggenheim Foundation, as well as the leaves of absence granted him by the Worcester Polytechnic Institute of Clark University, was Goddard able to sustain his lifetime of devoted research and testing.

Goddard first obtained public notice in 1907 in a cloud of smoke from a powder rocket fired in the basement of the Worcester Polytechnic Institute physics building. School officials took an immediate interest in the work of student Goddard. The school's administration, to their credit, did not expel him. He thus began his lifetime of dedicated work.
My father-in-law later was chased away as a kid by Goddard himself while playing in a field in Worcester, when Goddard was launching one of his early liquid-fueled rockets.
