Hyperbola-1

Hyperbola-1 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hyperbola-1 rather than just read about it. In short: The Hyperbola-1 (aka Shuangquxian-1, SQX-1) (Chinese: 双曲线一号) rocket is 20.8 m (68 ft) tall, 1.4 m (4 ft 7 in) in diameter and weighs 31 t (34 tons). It consists of four all solid fuel stages, guided by liquid fuel attitude control engines.

Key takeaways

Hyperbola-1 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Hyperbola-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hyperbola-1 from memory before moving on to harder problems.

Reference excerpt

The Hyperbola-1 (aka Shuangquxian-1, SQX-1) (Chinese: 双曲线一号) rocket is 20.8 m (68 ft) tall, 1.4 m (4 ft 7 in) in diameter and weighs 31 t (34 tons). It consists of four all solid fuel stages, guided by liquid fuel attitude control engines. It can launch 300 kg (660 lb) into low Earth orbit (LEO). The rocket might be based on Chinese military missiles (perhaps DF-11 or DF-15). The first stage of the rocket is equipped with four grid fins. The launch price is reported around US$5 million.

History The successful maiden flight was on 25 July 2019, at 05:00 UTC from Jiuquan Satellite Launch Center. It launched from a movable supporting platform. It placed numerous payloads, among them the CAS-7B amateur radio satellite, into orbit 300 km (190 mi) above Earth. CAS-7B decayed from orbit 6 August 2019. It was the first Chinese private company to achieve orbit (orbital launches of other private companies before had failed). A second launch occurred on 1 February 2021, at 08:15 UTC (16:15 Beijing Time) from Jiuquan Satellite Launch Center with 6 unidentified satellites but failed to reach orbit. A subsequent investigation revealed that a piece of insulation had broken off and got stuck in the turning mechanism of grid fin Number IV. When the piece was blown away, the control system then suddenly overcompensated, resulting in the rocket being ripped apart by excessive aerodynamic forces. The rocket was named "Tianshu" because its outer fuselage was covered with the artistic creations (images of compound made-up Chinese characters) of the contemporary artist Xu Bing. iSpace launched a third Hyperbola-1 solid-rocket vehicle on 3 August 2021. SpaceNews was reporting the same day that the outcome of the launch was unknown, but that amateur video of the launch had been posted, but then deleted from Chinese social media. After most of the day had passed, the Chinese official media Xinhua reported that the launch was unsuccessful due to off-nominal performance of the rocket which resulted in a failure to achieve orbit. An official statement released by the company itself the following day clarified that the failure was caused by a malfunctioning in the fairing separation process, that precluded the payload from reaching the target orbit. A fourth launch attempt on May 13, 2022, was unsuccessful as well. In April 2023, i-Space performed a fifth launch of the Hyperbola-1 which successfully reached orbit without a payload, and then followed with another launch on 17 December 2023 that placed the DEAR-1 satellite from Chinese company Azspace into a 500 kilometre SSO orbit.

Worked examples

Example 1 — a first encounter with Hyperbola-1

Start with the simplest possible case. Write down what Hyperbola-1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hyperbola-1 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hyperbola-1 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hyperbola-1

In research: Hyperbola-1 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hyperbola-1 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hyperbola-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Private space launch vehicles, Space launch vehicles of China, so understanding it makes those chapters shorter.
In everyday life: Look for Hyperbola-1 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Hyperbola-1 in simple terms?

Why does Hyperbola-1 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Hyperbola-1?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
