Talisman UUV

Talisman UUV is a engineering 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 Talisman UUV rather than just read about it. In short: The Talisman UUV is a fully autonomous unmanned mini-sub designed and made by BAE Systems. It has the capability to perform shoreline reconnaissance when the risks may be deemed too high, or conditions unsuitable, for human operators.

Key takeaways

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

Reference excerpt

The Talisman UUV is a fully autonomous unmanned mini-sub designed and made by BAE Systems. It has the capability to perform shoreline reconnaissance when the risks may be deemed too high, or conditions unsuitable, for human operators. The Talisman system comprises a vehicle and remote control console. The vehicle can be re-programmed in mid-mission by satellite and features a carbon fibre hull giving it a stealth-like profile and low observability. Talisman can carry a wide variety of payloads, such as image capture, environmental sensors or mine counter measures.

Programme history The Talisman programme was launched in late 2004, and was developed and managed by BAE Systems Underwater Systems and went from paper to initial trials in less than a year. Talisman has undergone a series of trials in the Irish Sea, with 100 per cent success rate. During further trials in late 2006, Talisman has become the first UUV to successfully fire and control weapons at sea during trials off the South Coast of England. The first remote sea launch of the Archerfish mine disposal system from Talisman was successfully completed during the trials. The mine neutraliser then acquired Talisman and subsequently simulated target eradication. In another deployment, also from the Talisman UUV, Archerfish successfully identified and acquired BAE Systems' versatile exercise mine system (VEMS).

The vehicle The Talisman vehicle is based on an innovatively shaped carbon fibre composite hull, with internal pressure vessels containing the electronics systems and payload. The stealthy hull design was based on BAE Systems’ aircraft technology. The vehicle weighs 1800kg, is approximately 4.5m long by 2.5m wide, can dive to 300m and has a top speed of 5 knots (9 km/h). It is fitted with vectorable thruster pods, which allow it to manoeuvre very accurately in difficult conditions, including strong currents, and over an extended period of time: the Talisman can be deployed 50 miles offshore and remain in operation for 24 hours. The precise handling in all directions comes from six thrusters, two at the front, and four at the back in two pairs. A rotary actuator is used to vector each pair of thrusters and to operate the hydroplanes. Talisman has been designed with a software architecture, which allows easy and rapid re-configuration of the mission systems. All mission parameters are pre-settable before launch, for full autonomous operation, with the possibility of operator intervention throughout the mission. Communications to and from the vehicle are via RF while the vehicle is surfaced and via acoustic communications systems when the vehicle is underwater.

Payloads As standard the vehicle is equipped with a suite of environmental sensors. Other payloads are mission or role specific and can include sonar systems, mine countermeasures and even other UUVs such as Archerfish.

Worked examples

Example 1 — a first encounter with Talisman UUV

Start with the simplest possible case. Write down what Talisman UUV claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Talisman UUV 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 Talisman UUV 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 Talisman UUV

In research: Talisman UUV appears in engineering 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 Talisman UUV 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: Talisman UUV is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2004 robots, BAE Systems, Military robots, so understanding it makes those chapters shorter.
In everyday life: Look for Talisman UUV 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.
