RX (rocket Family)
The RX rocket family (''Roket Eksperimental'', en, Experimental Rocket) is a series of solid-fuel rockets developed by the Indonesian National Institute of Aeronautics and Space (LAPAN). They are simply named by their diameter in millimeters; for example, the RX-250 has a diameter of . Individual boosters This family is composed of: RX-250 was launched eight times from 1987 to 2007. RX-320 was launched twice in 2008 and once again in 2014. RX-420 flew just once in 2009; it is superseded by RX-450 which was launched on 13 May 2015 , the next booster version RX-550 is under construction; the larger ones are only on the drawing board. Multi-stage rockets Once the solid boosters are fully qualified, LAPAN plans to assemble several of them into multi-stage rockets called ''Roket Pengorbit Satelit'' or ''RPS''. Four staging configurations have been retained so far: * RPS-01 Variant 1 (ex-RPS-420) :* First stage: 3 x RX-420 :* Second stage: 1 x RX-420 :* Third stage: 1 x RX-420 ...

National Institute Of Aeronautics And Space
National Institute of Aeronautics and Space ( id, Lembaga Penerbangan dan Antariksa Nasional, LAPAN) was the Indonesian government space agency. It was established on November 27, 1963, by former Indonesian president Sukarno after one year's existence of an informal space agency organization. LAPAN is responsible for long-term civilian and military aerospace research. For over two decades, it managed satellites and domain-developed small scientific-technology satellites Lapan and telecommunication satellites Palapa, which were built by Hughes (now Boeing Satellite Systems) and launched from the US on Delta rockets or from French Guiana using Ariane 4 and Ariane 5 rockets. It has also developed sounding rockets and has been trying to develop small orbital space launchers. The LAPAN A1 in 2007 and LAPAN A2 satellites were launched by India in 2015. With the enactment of Presidential Decree No. 33/2021 on 5 May 2021, BATAN is due to be disbanded along with government research a ...

Indonesia
Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at . With over 275 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population. Indonesia is a presidential republic with an elected legislature. It has 38 provinces, of which nine have special status. The country's capital, Jakarta, is the world's second-most populous urban area. Indonesia shares land borders with Papua New Guinea, East Timor, and the eastern part of Malaysia, as well as maritime borders with Singapore, Vietnam, Thailand, the Philippines, Australia, Palau, and India ...

Solid-fuel Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants ( fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Arabs, Chinese, Persians, Mongols, and Indians as early as the 13th century. All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications for their simplicity and reliability. Since solid-fuel rockets can remain in storage for an extended period without much propellant degradation and because they almost always launch reliably, they have been frequently used in military applications such as missiles. The lower performance of solid propellants (as compared to liquids) does not favor their use as primary propulsion in mode ...

Hydroxyl-terminated Polybutadiene
Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup. The properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers' specific requirements. A typical HTPB is R-45HTLO. This product consists of oligomeric units typically containing 40–50 butadiene molecules bonded together, with each end of the chain terminated with a hydroxyl Hgroup: R-45HTLO has a functionality of 2.4-2.6, which means that there is (approximately) one additional hydroxyl group located along the chain for every two oligomeric units. This provides side-to-side linkage for a stronger cured product. HTPB is usually cured by an addition reaction with di- or poly-isocyanate compounds.

RPS-420
Satellite Orbiting Rocket Number 420 ( Indonesian: Roket Pengorbit Satelit 420, abbreviated as RPS-420), or Pengorbitan-1, was a proposed space launch vehicle under consideration in Indonesia from 2008 to 2012. Recent developments have focused on a larger core stage called RX-420 and a smaller upper stage called RX-320, so this particular version RPS-420 is not being pursued any longer. However the goal remains valid: Indonesia aims to reach orbit with self-made rockets and satellites in order to become an Asian space power. The RPS or "Pengorbitan" (Indonesian for "orbital") will be an ultra-light orbital launch vehicle derived from the "RX" (''Roket Eksperimental'') rocket family. Several multistage launchers are being developed by the state company Spacetecx for Indonesia's National Institute of Aeronautics and Space (LAPAN). They will be launched from the Stasiun Peluncuran Roket facility in Pameungpeuk, where RX-250-LPN mini-rockets have blasted off already. No timelin ...

Orbital Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pads, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are classified by their orbital payload capacity, ranging from small-, medium-, heavy- to super-heavy lift. Mass ...
