SECAN Courlis

SECAN Courlis 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 SECAN Courlis rather than just read about it. In short: The SECAN SUC-10 Courlis (en: Curlew) was a French high-wing touring monoplane designed and built by Société d'Etudes et de Construction Aéronavales (SECAN), a branch of the automobile company Société des Usines Chaussons. The aircraft had problems with the engine installation and only 144 were built, some without engines and were scrapped.

Key takeaways

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

Reference excerpt

The SECAN SUC-10 Courlis (en: Curlew) was a French high-wing touring monoplane designed and built by Société d'Etudes et de Construction Aéronavales (SECAN), a branch of the automobile company Société des Usines Chaussons. The aircraft had problems with the engine installation and only 144 were built, some without engines and were scrapped.

Development The Courlis was an all-metal high-wing cantilever monoplane with twin booms supporting a tail unit. It was powered by a 190 hp (142 kW) Mathis G8R piston engine mounted in the rear fuselage in a pusher configuration. It had a fixed tricycle landing gear and had four seats in the enclosed cabin. The prototype, registered F-WBBF, first flew on 9 May 1946. Production was started and a total of 144 aircraft were completed with a number being exported to South America. Problems with the engine (insufficient power, cooling) resulted in the withdrawal of the engine's type certificate and some airframes were never fitted with an engine and scrapped. The company did test fit the aircraft with a 220 hp (164 kW) Mathis engine but production was ended. The aircraft flew for some years, owned by French private pilots, but by the mid-1950s, most had been withdrawn from service, with many being stored at Mitry-Mory airfield near Paris. In 1961 the design was revised as the SUC-11G Super Courlis with a 240 hp (179 kW) Continental O-470M engine, but was abandoned after a prototype was built.

Variants SUC-10 Courlis Production variant with a 190hp Mathis G.8R engine, 144 built (not all flown). SUC-11G Super Courlis Improved design with a 240hp Continental O-470M engine, only one built.

Aircraft on display One aircraft is held by the Musée de l'Air et de l'Espace, Le Bourget, Paris, France, but is not currently (2007) on public display.

Worked examples

Example 1 — a first encounter with SECAN Courlis

Start with the simplest possible case. Write down what SECAN Courlis 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 SECAN Courlis 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 SECAN Courlis 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 SECAN Courlis

In research: SECAN Courlis 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 SECAN Courlis 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: SECAN Courlis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s French civil utility aircraft, Aircraft first flown in 1946, High-wing aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for SECAN Courlis 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.
