Advanced Rocket Research Center (ARRC; Chinese: 國立交通大學前瞻火箭研究中心) is a Taiwanese space transport research organization headquartered at National Chiao Tung University in Hsinchu City, Taiwan, with a research focus in hybrid rockets.[1][2][3] Founded in April 2012, AARC is supported by research grants and private donors through crowdsourcing platforms.[4][5]

Introduction

ARRC is jointly organized by multiple universities in Taiwan. It was established at National Chiao Tung University in June 2012 and funded by corporate and private donations.

The main participants include Distinguished Professor Jong-Shinn Wu, Professor Tsung-Lin Chen from National Chiao Tung University, Associate Professor Ming-Tzu Ho from National Cheng Kung University, Professor Hui-Wen Hu from National Pingtung University of Science and Technology, Professor Hsin-Piao Lin from National Taipei University of Technology, Assistant Professor Jen-Perng Yu from Ming Chuan University, and Assistant Professor Juan-Chen Haung from National Taiwan Ocean University. Jong-Shinn Wu is now the chairman of the group.

Launches

On 24 March 2014, ARRC test launched the HTTP-3S rocket near the coastlines of Pingtung County. The HTTP-3S rocket was one of the largest hybrid sounding rockets launched by civilians in Taiwan, with a length of 6.35 m, a diameter of 0.4 m, and a weight of 300 kg. It was propelled by a multi-cluster vortex mixed booster hybrid engine which employed nitrous oxide as oxidizer. The engine was capable of delivering 1,000 kgf thrust (with Isp up to 250 seconds). The goal of the HTTP-3S launch campaign was to test functions of all subsystems during the drastic high-speed flight scenario. The flight data gathered during the successful test launch will be used for the second stage rocket design of future dual-stage sounding rockets and the validation of launch site safety measures.[6][7][8][9][10]

On 18 April 2015, ARRC test launched the APPL-9β sounding rocket at the Siangshan Wetland in Hsinchu City. The APPL-9β rocket was propelled by a solid state fuel in the first stage and a hybrid fuel in the second stage. The casing was made of a PLA material by 3D printing. The rocket carried a test satellite made by National Central University.[11]

Test Projects

APPL

The APPL rocket adopted solid sugar rocket engine as the propellant. It is a kind of solid rocket made with sugar as a fuel and containing an oxidizer. This type of rockets are also known as sugar rocket. APPL is named after the Aerothermal & Plasma Physics Laboratory in National Chiao Tung University, which began to develop and manufacture small rockets under the leadership of Professor Jong-Shinn Wu in 2007. Because the sugar rocket is safe and easy to manufacture, and also produce less pollution, it thus became the first rocket made by the group. Since ARRC was formally established in 2012, APPL rockets have been used in tests of several secondary systems of large rocket, so that the systems can be applied to the HTTP Hybrid Rocket.[12]

  • APPL-0 alpha Jun 22, 2008, the first flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off. However, due to the excessive force acting on the cone, it was broken and the parachute was accidentally pulled out. Therefore the parachute was opened when the rocket landed. [13]
  • APPL-0 beta Jun 22, 2008, the second flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket has broken apart on the launch pad after ignition. [14]
  • APPL-1 also called APPL-I. Jan 18, 2009, the third flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off. The parachute did not open completely, yet the rocket still landed. The fly height was 835 meters.[15]
  • APPL-2 also called APPL-II. Jun 28, 2009, the fourth flight test of ARRC was held at Siangshan Wetland, Hsinchu. APPL-2 is a multistage rocket with solid fuel as the propellant. After the first stage booster was exhausted and separated, the second stage was successfully ignited. However since the rocket flew too far, it was failed to retrieve and analyze the flight condition.[16]
  • APPL-3 also called APPL-III. Sep 7, 2009, the fifth flight test of ARRC was held atChanghua Coastal Industrial Park. Because of a malfunction of the booster, the rocket has exploded and broken apart in a second after released from the launch pad. The parachute was working normally after the explosion.[17]
  • APPL-4 also called APPL-IV. Jan 24, 2011, the seventh flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off. The parachute did not open when it landed. The fly height was about 500 meters.[18][19]
  • APPL-5 1also called APPL-V 1, Mar 10, 2011 the eighth flight test of ARRC was held at Siangshan Wetland, Hsinchu. Because of a malfunction of the booster, the rocket crashed in flame after launched.[20]
  • APPL-5 2 also called APPL-V 2. Mar 10, 2011, the ninth flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off and separated. But the parachute didn’t completely pulled out as landing.[21]
  • APPL-6 also called APPL-VI. May 9, 2011, the tenth flight test of ARRC was held at Siangshan Wetland, Hsinchu. Because the connecter between the rocket and the launch pad was broken, the rocket was not flown. The rocket stayed on the launch pad till the fuel was exhausted.[22][23]
  • APPL-6 2also called APPL-VI 2, Jun 24, 2011, the eleventh flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off. The v-band didn’t work smoothly so it was failed in separation. The parachute didn’t open as well. The aim of this test is to examine v-band on two-stage rocket.[24][25]
  • APPL-mini 1 is a small solid sugar rocket developed for the camp [26] organized by National Space Organization. It is a small rocket without electrical control. There were in total 12 APPL-mini 1 small rockets made by both students and lecturers launched in 青青草原 on Jul 20,2012. It was the fourteenth flight test of ARRC.[27]
  • APPL-mini 2 is a small solid sugar rocket developed for the camp[28] organized by National Space Organization. It is a small rocket without electrical control. There were in total 11 APPL-mini 2 small rockets made by both students and lecturers launched in 青青草原 on Jul 18,2013. The rocket made by lecturers was installed a smartphone inside to record the flight information.[29]
  • APPL-Banan 1 Sep 1, 2013, the sixteenth flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket was carried to the air by a balloon with a diameter of 3 meters and expected to release at 1000 meters high. However the rope used to connect the balloon and the rocket was loose and the rocket dropped at 30 meters high. The aim of the test is to examine the parachute recycle system and the immediate data transmission technology on avionics system of HTTP-2ß. [30]
  • APPL-7 Nov 9, 2013, the seventeenth flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off but the recycling system is down. The rocket ultimately crashed.[31]
  • APPL-7 II Dec 28, 2013, the eighteenth flight test of ARRC was held at Siangshan Wetland, Hsinchu. This time the rocket adopted 2 reserve parachutes and 1 main parachute recycling system. The rocket successfully lifted off and the parachutes open sequentially. [32]
  • APPL-8 Jan 26, 2014 the nineteenth flight test of ARRC was held at Siangshan Wetland, Hsinchu. The rocket successfully lifted off and the fly height approach to 1000 meters.[33]
  • APPL-9 α Jan 4, 2015, the twenty-first flight test of ARRC was held at Siangshan Wetland, Hsinchu. APPL-9 αis a two-stage rocket. The first stage is solid rocket with sugar as the fuel. And the second stage is hybrid rocket with nitrous oxide as the liquid oxidizer. The body tube of the rocket was made by 3D printing technology, and attached the glass fiber inside of the nose cone to reinforce the strength. [34] Since the solid engine on the first stage was broken, it exploded as ignition process. The second stage was ignited after the explosion and was horizontally propelled forward some distance. All of the three parachutes were pulled out during the propelling period. The aim of this test is to examine the avionic device on the two-stage rocket.[35]
  • APPL-9 ß Apr 18, 2015 the twenty-second flight test of ARRC was held at Siangshan Wetland, Hsinchu.[36] Base on the failure of APPL-9 alpha, this time ARRC employed the PLA as the material of the 3D printed body tube. Also, the self-made glass fiber shell was used to strengthen it.[37][38][39]The rocket successfully lifted off but didn’t separate due to the malfunction of v-band. For safety reasons, the second stage didn’t ignite. It had been verified that two explosive bolts induced the problem. The parachute was pulled out and open while the rocket was plunging. [40]
  • APPL-9 C Jan 31, 2016, the twenty-second flight test of ARRC was held at Siangshan Wetland, Hsinchu. ARRC made a small two-stage rocket with similar configuration in APPL-9 alpha and APPL-9 beta. This was used to test the secondary system on HTTP-3, including the stability of avionic system and the separation device. The body tube adopted the same material as APPL-9 beta. The first stage is solid rocket, fueled by sugar and oxidizer. And the second stage is hybrid rocket with Nitrous oxide as the liquid oxidizer and polyethylene as the fuel. The total weight of the rocket is about 27 kg.[41] [42] The rocket successfully lifted off and separated. Both stages of the rocket were equipped with parachutes. The parachute on first stage didn’t work. And those three parachutes on the second stage opened as expected. The fly height is about 1100 meters. [43] [44]
  • APPL 10 launched on Dec 1,2018. The rocket is 3.2 meters long with 0.156 meters of diameter. The total weight is 30kg and the expected fly height is around 1000 meters.[45]。APPL 10 was failed in separation system and didn't make the expected height.[46]
