Nieuport-Delage NiD 940

Nieuport-Delage NiD 940 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 Nieuport-Delage NiD 940 rather than just read about it. In short: The Nieuport-Delage NiD 940 was a French, tailless, pusher configuration touring aircraft first flown in 1934. It suffered from longitudinal instabilities and despite modifications and a more powerful engine, it did not receive its Certificate of Airworthiness.

Reference excerpt

The Nieuport-Delage NiD 940 was a French, tailless, pusher configuration touring aircraft first flown in 1934. It suffered from longitudinal instabilities and despite modifications and a more powerful engine, it did not receive its Certificate of Airworthiness.

Design and development The NiD 940 was a low cantilever wing aircraft. Its wing had a thick section and a chrome-steel tube structure and in plan was swept with straight-taper. Elevons, hinged at right angles to the line of flight, controlled both pitch and roll. Triangular wing tip fins, externally braced from tip to wing, provided yaw stability and carried generous, five-sided, angular rudders which could operate together for directional control but also be opened at right angles as air brakes. The wings could be folded for transport. The fuselage of the NiD 940 was also a steel tube structure, flat-sided and short, not reaching the wing trailing edge. It was covered with tulipwood plywood overlain with fabric. A well glazed cabin provided two side-by-side seats, with room for a third seat and baggage space behind them. The steel structure also mounted an 89 kW (120 hp) Lorraine 5Pc five-cylinder radial engine in uncowled pusher configuration. The NiD 940 had tricycle landing gear, with its mainwheels on V-struts hinged from the lower fuselage and with vertical shock absorber legs to the wings. Wingtips were protected by skids mounted on the bottom of the fins. The nosewheel was large and well forward. In its initial form the prototype was known as the NiD 941. Though this was on display in November 1932 at the 13th Paris Salon de l'Aviation, it did not fly until February 1934, piloted by Nieuport's test pilot Joseph Sadi-Lecointe. The early trials showed a lack of longitudinal stability. Despite modifications and a new 101 kW (135 hp) Salmson 9Nc nine-cylinder radial engine, after which it became the NiD 942, an airworthiness certificate was not granted.

Variants NiD 941 original aircraft with Lorraine 5Ps engine. NiD 942 modified aircraft with Salmson 9Nc engine.

Worked examples

Example 1 — a first encounter with Nieuport-Delage NiD 940

Start with the simplest possible case. Write down what Nieuport-Delage NiD 940 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 Nieuport-Delage NiD 940 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 Nieuport-Delage NiD 940 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 Nieuport-Delage NiD 940

In research: Nieuport-Delage NiD 940 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 Nieuport-Delage NiD 940 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: Nieuport-Delage NiD 940 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930s French sport aircraft, Aircraft first flown in 1934, Low-wing aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Nieuport-Delage NiD 940 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.
