2019-2028 Roadmap


The Republic Of China (Taiwan) Lunar Exploration Program
Space Development Phase 3

Latest update: 2019/02/13 14:56

The Phase 3 plan for space exploration will last for 10 years. From 2019 to 2028, the investment will be NT$25.1 billion.

The space exploration project for Space Development Phase 3 will also develop at least one lunar orbiter.

Lin Junliang said that the First Phase must carry out the design and research of the Lunar Orbiter, and the Second Phase is the Lunar Lander. Since the orbiting the moon is different from the earth low-orbiting satellite, their is needs to have the sound ground communication technology, radiation resistance and orbital manoeuvering foundations.

Solid propellant space launcher program


The Republic Of China (Taiwan) Solid Propellant Satellite Launch Vehicle Program
2019年01月08日 21:46:00

The Ministry of National Defense has developed a space launch vehicle capable of placing a 50 to 200 kilograms microsatellites into a 500-kilometer SSO orbit, under the code name "Kirin Project" (麒麟專案). It is reported that this year three sets of rocket propulsion vehicles were built. The entire project plans to manufacture six sets of rocket propulsion vehicles. After ground testing, the first flight-test will be carried out smoothly in 2021.

It is reported that starting from this year, after the Kirin project first produced three sets of rocket propulsion vehicles, each for static ground testing works, the entire project plans to manufacture six sets of rocket propulsion vehicles.

After completing the various ground testing, system integration and system testing are carried out.

Because the launch vehicle is a four-stage solid-fuel rocket, each stage separation requires a telemetry and control system. The flight attitude control cannot pilot the rocket after take off. This requires guidance. Technology that is the focus of the "Star Show Project" (星展專案). In addition, due to the weight of the rocket carrier, whether the launch platform of the existing Jiupeng base (九鵬基地) can bear the weight, the Chinese Academy of Sciences will carry out geological exploration to ensure the safety of the launch pad.

First hybrid propellant space launcher HAPITH-I


Taiwanese Company Aims At Launch Costs 10% Of Competitors’

Aerospace Daily & Defense Report

Oct 24, 2019

Bradley Perrett


Hot fire test of Tispace 1-metric-ton-thrust engine: Tispace

A Taiwanese company plans to enter the market for light space launches with what it says will be 10% of the costs of current major operators, thanks to an efficient production setup and use of hybrid solid-liquid propulsion.

Launch of a two-stage demonstrator rocket is scheduled for November, to be followed by monthly launches of larger production rockets in 2021, said Yen-Sen Chen, founder and CEO of the company, Taiwan Innovation Space (Tispace).

At first, each launch by the expendable, three-stage Hapith V production rocket will be priced at $6-7 million, Chen said. This will deliver up to 390 kg (860 lb.) to a low-inclination orbit of 600- 700 km (370-430 mi.). “We have lots of room for a lower price,” Chen added, since costs would be so low.

The initial production facility near Taipei, with a capacity of 12 rockets a year, will be able to achieve the targeted cost of 10% of competitors’, Chen said. But the company is looking for a larger site farther south for a plant that could build 100 rockets a year.

Engines of the Hapith V and the Hapith 1 demonstrator are almost devoid of machinery. Being hybrid, they do not require the elaborate production and handling facilities of potentially explosive solid-propellant motors.

The fuel is a special hard rubber, made in Taiwan. The oxidizer is nitrous oxide fed to the engine by tank pressure, which begins at 6 MPa (870 psi.) at launch, falling to 1 MPa at the time of engine cutoff; there are no turbo pumps.

Tispace has tested engines of various thrust levels. Specific impulse, a measure of propulsion efficiency, will be 270 sec. for the first stage and 301 sec. for the second and third, the company estimates. This is regarded as adequate rather than exceptional, since the most important engine characteristic is simplicity and adaptability to low-cost production.

A contractor will supply the fuel in the single cylindrical block needed for each engine, Chen said. No trimming or other adjustment of shape will be required. Insulation will be placed manually on the fuel blocks, then uncured carbon fiber composite will be laid around them automatically to create the case. The engine will then go into an oven for unpressurized curing of the composite at 90C (190F).

The oxidizer tanks will similarly be made automatically with the same, T800-grade carbon fiber composite. The company chose carbon fiber in preference to the usual aluminum to reduce weight. The company also believes carbon fiber suits low-cost fabrication. About 90% of the Hapith V structure is made of the material.

The engines use commercially available valves and stainless steel piping. Injectors, of proprietary design, will be made with 3D printing.

Attitude control is effected in the first stage by venting nitrous oxide and in the second and third stages by gimballing the engines (that is, the encased rubber blocks).

Chen set up the company in 2016, having previously worked for Taiwan’s National Space Organization. It has 105 employees, he said, speaking on the sidelines of the International Astronautical Congress, held in Washington Oct. 21-25.

The demonstrator is complete and ready for its Nov. 28 launch. It has a weight of 3.04 metric tons and launch thrust of 7.92 metric tons.

The company has begun making the first Hapith V. That 20-m (66-ft.) design has a weight of 35 metric tons and launch thrust of 65 metric tons from five engines. The second stage has four engines and 8 metric tons of thrust; the third has one engine generating 1 metric tons of thrust. Payload to Sun-synchronous orbit is 350 kg.

The company’s launch site is at the southern end of Taiwan, facing the empty Pacific Ocean. With inhabited islands to the north and south, Taiwan is unsuitable for launches to Sun- synchronous orbit, so Tispace is looking at options in Scandinavia. Australia is also a possibility.

Rockets are to be moved to the Taiwanese launch site by truck and to the chosen foreign one by air.

Maiden launch scheduled for 27th December 2019
2019-12-26 08:58:31

The promotion of the space technology companies in Taitung ’s space exploration rocket has attracted attention from all walks of life. However, due to local concerns, the launch operation will be suspended and a briefing will be held today. The relevant person said today that the promotion company hopes to obtain local public opinion supports and strives to launch as scheduled tomorrow (27th). If the planned launch operation can be carried out according to the original plan, the projectiles of the space exploration rocket will fall into the waters 30 kilometers east of Green Island and Lanyu.

Relevant sources also said that if it is difficult to successfully launch on the 27th of this month, the next launch date will be on January 22 next year.

The Maritime Safety Administration, the Agriculture Commission, the Civil Aviation Bureau of the Ministry of Communications, the Port Bureau and the military have issued sea and air area control notifications in accordance with previous plans, calling on vessels and aircraft in various areas to avoid the controlled sea and air areas launched by rockets.

The promotion company had previously stated that once the space exploration rocket was launched, the entire rocket had a range of about 10 minutes and fell after reaching 200 kilometers. However, according to the application file of the promotion company, the maximum ballistic altitude of the space exploration rocket was 300 kilometers. A space exploration rocket can reach a higher altitude. If the rocket launches smoothly, the small satellites carried next time will be able to be sent directly into space orbit.

In order to perform the launch mission of the National Space Center's multi-purpose sounding rocket scientific experiment, the promoted space technology company once invited the relevant units to coordinate the sea and airspace control operation. According to the launching notice (sea and airspace) issued by the Coastal Inspection Agency and the Agricultural Committee Control sheet), from 6 am to 7 am on the 27th, it will be launched at the Taidong Nantian launch base (台東南田發射基地). The rocket's projectiles are expected to fall in the waters 30 kilometers away from the middle of Green Island and Lanyu.

Abnormal guidance system's signal: 2nd Hapith-I launch attempt scheduled for 18th February 2020
2020/02/13 08:23

TiSpace Corporation, Taiwan ’s first private company’s self-made sounding rocket 'Flying Squirel One' was originally expected to test fire at 6 am in Nantian, Daren Township, Taitung County.

The launch procedure was already started when at the last minute, an abnormal system signal was detected. Finally, the launch procedure was aborted, and the NO2 fuel was released into the air, disappointing hundreds of people who came to watch the rocket maiden test launch.

The company also stated that it would try to launch the rocket again after finding the cause.

TiSpace company built a base to launch a test rocket around the Nantian tribe. The news was disclosed last December. The tribe residents expressed their dissatisfaction, strongly questioning the legitimacy, and worried about the danger posed to the tribe's security and environmental ecology. Later, the central government came forward to solve the decree, and Tispace has also been intensively communicating with localities for more than a month.

There was a heavy rain on the scene this morning, but it did not quench the enthusiasm of hundreds of people. Everyone made a special trip to get ready to enjoy the wonderful picture of the first domestic private company's test rocket launch, but they were disappointed.

Taking pictures of the rocket outside, Tispace company said that it is expected to conduct another test launch in the early morning of February 18th.

The weather was of the worse, with storm all the previous night. Then high altitude wind would even burst weather balloons released at dawn by the meteorologists.

Finally the decision was taken to go ahead with the maiden launch of Hapith-I sounding rocket.

After ignition, an abnormal signal was detected, and decision to cutoff the engines at ~20 seconds, aborting the takeoff.

Launch site issues force rocket firm overseas: sources

Fri, May 07, 2021 page2

The lack of an approved launch site in the nation has forced Taiwan Innovative Space Inc to turn to Australia to launch a research rocket, sources familiar with the matter have said.

Some Taiwan Innovative Space employees departed for Australia in February to complete quarantine and preparatory procedures prior to trial launches this month, a person said on condition of anonymity.

Australian space company Southern Launch would help Taiwan Innovative Space launch its sounding rocket at a site near Adelaide, South Australia, another person with knowledge of the matter said.

“On 25 March, the Australian government announced the first ever license for a space launch facility, legally permitting rockets to fly into space from Australian territory,” Southern Launch said in a news release last month.

“With domestic launch sites for commercial use, no more will Australia send money and give away jobs to the launch industries of New Zealand, the United States, Europe or India,” it said.

Taiwan Innovative Space had not responded to the Taipei Times’ requests for comment as of press time last night.

Founded in 2016, the company aims to become Taiwan’s first commercial rocket supplier for microsatellite launch services, but it has yet to prove its capabilities with flight data.

On Feb. 13 last year, it attempted to launch its Hapith-I rocket at a site in Taitung County, but the mission was terminated due to inclement weather.

The company wrote on Twitter at the time that “the process of ignition was completed.”

Subsequent activity at the site was thwarted amid controversy over whether the site was being used illegally.

Taiwan Innovative Space chairman Chen Yen-sen (陳彥升) had said that the firm might launch the Hapith-I in Alaska.

However, the situation might be “a turning point” for the company, as overseas firms and investors have noticed that there is a rocket supplier in Taiwan, one of the sources said.

Its Australia launch plan, apart from proving its capabilities, is aimed at fulfilling a contract with the National Space Organization (NSPO), which commissioned it to launch a scientific payload with a hybrid rocket at a cost of nearly NT[imath]50 million (US[/imath]1.79 million).

Completing the mission abroad is a result of a “compromise,” due to the lack of an approved launch site in Taiwan, schedule pressure and pressure from some lawmakers, NSPO Acting Director-General Yu Shiann-jeng (余憲政) said on Monday.

The NSPO and Taiwan Innovative Space revised their contract, requiring the company to launch the payload at an approved overseas site by the end of July, Yu said.

The NSPO requires the company to launch the payload to an altitude of 150km or higher, but did not designate where the launch should take place, he said.

The company pays for its overseas expenses, while its negotiations with launch service providers do not pass through the NSPO, he said.

From 1997 to 2014, the NSPO commissioned 10 sounding rocket projects.

Some of the solid-propellant rockets carrying scientific payloads, such as ionosphere probes, reached 300km, without entering orbit.

Hybrid rockets developed by Taiwan Innovative Space or local academics have not yet reached 150km, so the mission is a challenge, Yu said.

Whether the company would use Hapith-I, which was unveiled in 2019, to launch the payload is unknown, as it has made several similar models, he said.

Asked if NSPO personnel would fly to Australia to observe the mission, he said that it would make a decision after the company clarifies the situation.

Yu said that “it is hard to predict at the moment” what the impact would be if Taiwan Innovative Space were forced to go abroad every time it has to launch a rocket.

“Establishing a rocket launch site is a whole new issue for Taiwan, so there are many things to consider, such as the opinions of the public and different government agencies,” he said. “Whether there is room for commercial services also needs deliberation.”

A draft space development bill that last week passed preliminary review at the legislature would designate the Ministry of Science and Technology, which oversees the NSPO, to establish a national rocket launch site.

A local launch site would make scientific endeavors easier to plan.

The altered launch site for the Taiwan Innovative Space mission means that the data its payload is to deliver might affect the scope of the project.

The mission is to carry an ionosphere scintillation package developed by National Central University (NCU).

Their Australian collaborators have asked them to share the data, as those experiments have never been conducted over Australia, NCU Department of Space Science and Engineering director Chao Chi-kuang (趙吉光) said.

While the sounding rocket’s flight is projected to last only about 10 minutes, it would allow researchers to test the functionality and stability of the instruments in a space setting.

Australian researchers can use ground-based radar stations to observe the ionosphere, but the probe can measure ionospheric structures with greater precision, as experiments using Taiwan’s sounding rockets have shown, Chao said.

It is not known whether there are significant differences between the ionosphere over Taiwan and over Australia, so the mission is an opportunity for new cooperation, he said.

Chao said that he and other researchers might visit Australia for the mission, but they are waiting for NSPO funding for travel expenses.

Former Australian representative to Taiwan Gary Cowan in November last year met with Chen at a hydrogen energy seminar, the Australian Office in Taipei wrote on Facebook at the time.

Chen is a member of the Taiwan Hydrogen Industrial Development Alliance.

Asked if it is helping Taiwan Innovative Space in Adelaide, or whether Cowan and Chen had exchanged opinions about launches, the office on Tuesday said it had no comment.

HTTP-3AT hybrid propellant rocket tethered hovering flight

Demonstration of tethered hovering flight of HTTP-3AT hybrid rocket

Highlights

• Demonstration of the first-ever hovering flight test using hybrid rocket engines.
• Preliminary verification of the capability of the vertical landing of hybrid rocket.
• Validation of precise thrust control of the hybrid rocket engine.
• Controlling the oxidizer mass flow rate by using an industrial ball valve.
• Validation of direct-drive TVC for the hybrid rocket engine.

Abstract

This study demonstrated the performance of flight control systems of a hybrid rocket in a hovering flight test by developing a rocket designated HTTP-3AT powered by High Test Peroxide (HTP, a term used for concentrated hydrogen peroxide, H2O2).

Hybrid rocket excels in system simplicity, operational safety, oxidizer storability, cost, and throttling capability compared to current solid and liquid rocket engine systems. Although issues such as the severe oxidizer-to-fuel (O/F) ratio shift during combustion and difficulty in gimbaled thrust vector control (TVC) caused by the lengthy chambers need to be solved, hybrid rocket propulsion is nevertheless a promising propulsion technology for future space exploration. To achieve accurate orbit insertion, thrust magnitude control and TVC of the rocket engines are necessary. However, no organizations have successfully implemented this technology on a practical hybrid rocket, not even using this technology for hovering flight tests.

On September 8th, 2020, a hovering flight test of HTTP-3AT was conducted, achieving a steady hover 3 m above ground for 25 s utilizing both attitude and position controls. This test showed that a hybrid rocket could achieve a stable hovering flight with the capability of vertical takeoff and vertical landing (VTVL), demonstrating excellent throttling control and TVC capabilities of hybrid rocket propulsion.

HTTP4 hybrid propellant VTVL sounding rocket


7 JAN 2022

As you may have noticed, we will also be launching HTTP-4 this year.

HTTP-4 is a two-year project under the MOST (Ministry of Science and Technology) program which will continue to implement the technology developed in HTTP-3AT, and conduct remote VTVL (Vertical Takeoff and Vertical Landing) hopping flight tests.
