RUAG Ranger

RUAG Ranger 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 RUAG Ranger rather than just read about it. In short: RANGER is a tactical UAV system (TUAV) built as a Swiss-Israeli joint venture between Swiss aerospace enterprise RUAG Aviation and Israeli aerospace company Israel Aerospace Industries. Its design and some of its technology is based on the Scout UAV system by Israel Aerospace Industries.

Key takeaways

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

Reference excerpt

RANGER is a tactical UAV system (TUAV) built as a Swiss-Israeli joint venture between Swiss aerospace enterprise RUAG Aviation and Israeli aerospace company Israel Aerospace Industries. Its design and some of its technology is based on the Scout UAV system by Israel Aerospace Industries. The RANGER UAV uses a compact hydraulic launcher for takeoff. Due to a modular payload, the system can be adapted to a wide range of civilian and military missions. A skid-based landing system enables the UAV to land nearly anywhere, on grass or on concrete runways, on snow or ice. According to the manufacturer, RANGER is the only tactical UAV system worldwide certified to fly in civilian airspace as well as over populated areas. The prototype is now at the Flieger-Flab-Museum in Dübendorf.

Operators The consortium delivered the first Ranger system to the Swiss Air Force in June 1999 upon successful completion of military exercise conducted by the Swiss Armed Forces. The RANGER system is in service with the Swiss Air Force under the designation ADS-95. From 1988 to 1999, an earlier variant called ADS-90 was in use. The Air Force's RANGERs are also used by Swiss police for reconnaissance, search and rescue missions. The current 15 ADS-95 will be replaced until 2019 by six Elbit Hermes 900. The last flight of a Swiss Air Force ADS-95 (D-124) was on 27 November 2017. The RANGER is also in service with the Finnish Defence Forces (FDF).

Former operators Switzerland (28) The drone were ordered with the Armament Programme 1995 for a budget of CHF 350 million, and they enetered service in 1999. Four systems were supplied, each equipped with: 7 UAV 2 catapults (electro-hydraulic) 2 mobile ground control stations, one of which has an automatic landing system 2 mobile data receiving stations 1 logistics setIt used to be operated by the Swiss Air Force 7th Unmanned Aerial Vehicle Squadron (German: Drohnen Staffel 7), at Emmen Air Base. Finland (12) 12 drones were operated by the Finnish Army.

Worked examples

Example 1 — a first encounter with RUAG Ranger

Start with the simplest possible case. Write down what RUAG Ranger 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 RUAG Ranger 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 RUAG Ranger 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 RUAG Ranger

In research: RUAG Ranger 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 RUAG Ranger 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: RUAG Ranger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1990s international military reconnaissance aircraft, Aircraft with skid landing gear, Israel Aerospace Industries unmanned aerial vehicles, so understanding it makes those chapters shorter.
In everyday life: Look for RUAG Ranger 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.
