Hydra Technologies Ehécatl

Hydra Technologies Ehécatl 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 Hydra Technologies Ehécatl rather than just read about it. In short: The S4 Ehécatl is an unmanned aerial vehicle developed and manufactured by Hydra Technologies of Mexico which, except for its infrared thermal sensor system, is the first of its type to be completely designed and manufactured in Mexico. It is named after Ehecatl, the Aztec god of the wind.

Key takeaways

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

Reference excerpt

The S4 Ehécatl is an unmanned aerial vehicle developed and manufactured by Hydra Technologies of Mexico which, except for its infrared thermal sensor system, is the first of its type to be completely designed and manufactured in Mexico. It is named after Ehecatl, the Aztec god of the wind.

Overview A prototype of the airplane was presented in the Paris Air Show at Le Bourget on June 19, 2007. In August 2007 at Washington D.C., a full-scale model was exhibited at the Association for Unmanned Vehicle Systems International (AUVSI) symposium, an aeronautics exposition with over 275 exhibitors. At the conclusion of the AUSVI symposium Hydra Technologies became the first non-U.S. recipient of the AUSVI's 'Al Aube Outstanding Contributor Award' for the development of the S4 Ehécatl UAS (Unmanned Aerial System). In 2008, Hydra Technologies received the Leonardo da Vinci award, given by the International Aeronautics Congress of Mexico (CIAM for its Spanish abbreviation) for the development of the S4 Ehácatl, as well as the E1 Gavilán. On August 3, 2008, the State of Jalisco and Coecytjal presented Hydra with an award in the 29th Annual National Convention of the National Chamber of Electronics, Telecommunications and Informatics Industry (CANIETI), for its contribution to the informatics, microelectronics and communications industries in Mexico.

Description The S4 Ehécatl is an aerial unmanned surveillance system whose development began in 2002. Its principal market is directed towards providing security and surveillance capabilities in support of the Armed Forces, as well as civilian protection in hazardous situations. Because of its small size and unmanned nature, it can enter dangerous zones without being detected. Apart from a U.S.-made FLIR infrared thermal sensor system, all of the S4 Ehécatl's componentry and avionics are designed, developed and manufactured in Mexico by the firm Hydra Technologies. The S4 Ehécatl has an electronic system that is designed to provide up to eight hours of autonomous flight, in either daytime or nighttime conditions. The craft is controlled from a mobile central facility installed in a specially equipped three-man ground vehicle. The surveillance capabilities of the UAV was suggested as an option to survey of the border problems between the U.S. and Mexico. The project developing the craft is a joint effort of the Mexican Federal Government, the Financial Sector, and Mexican academic and scientific institutions like CONACYT, the National Polytechnic Institute (IPN), the Autonomous University of Guadalajara and the Western Institute of Technology and Higher Education (ITESO).

Worked examples

Example 1 — a first encounter with Hydra Technologies Ehécatl

Start with the simplest possible case. Write down what Hydra Technologies Ehécatl 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 Hydra Technologies Ehécatl 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 Hydra Technologies Ehécatl 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 Hydra Technologies Ehécatl

In research: Hydra Technologies Ehécatl 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 Hydra Technologies Ehécatl 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: Hydra Technologies Ehécatl is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s Mexican military reconnaissance aircraft, Aircraft first flown in 2006, High-wing aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Hydra Technologies Ehécatl 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.
