Gillespie Aeroplane

Gillespie Aeroplane 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 Gillespie Aeroplane rather than just read about it. In short: The Gillespie Aeroplane was a 1900s monoplane built by the American architect G. Curtiss Gillespie and was notable for its very low aspect ratio wing.

Key takeaways

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

Reference excerpt

The Gillespie Aeroplane was a 1900s monoplane built by the American architect G. Curtiss Gillespie and was notable for its very low aspect ratio wing.

Design and development The Aeroplane was designed to address issues with stability and equilibrium that Gillespie believed previous flying machine designs had suffered from. His studies led him to design an aircraft with a very narrow span and a long chord, with control surfaces embedded into the wing's planform, so that the pilot could maximize the longitudinal control, and minimize the lateral instability or "upset" of the craft. Pitch control was to be achieved by two pairs of elevators, one front and one rear, both located within the planform of the wing. Lateral control was attended to by two movable surfaces, integrated into the wing, and located halfway along the chord. Directional control was through a flat-plate rudder located to the rear and underneath the wing. The wing was constructed from a rectangular framework made of aluminum tubing, reinforced with piano wire. It was covered with duck canvas. The airfoil was a flat plate with no incidence and no camber. The engine and pilot were located in a rectangular framework located underneath the wing. The engine was an air-cooled flat-six gasoline engine, said to develop 20 hp (15 kW). It powered the seven propellers using chain drives. Two sets of three propellers, located inboard of the wing tips, each shared a long drive shaft. The seventh propeller was located ahead of the wing's leading edge, close to two other propellers. Each propeller had four blades, and were made of aluminum.

The pilot lay in a prone position, just behind the engine. The monoplane featured a tricycle undercarriage, with a tailwheel positioned underneath the rudder and which would come into play, should the craft pitch up. There were no reports of the airplane's tests, nor of any flights that may have been made. In late 1906, the Aeroplane was displayed at the second annual exhibition of the Aero Club of America. Such was the rapid progress of aviation of the era, that a contemporary report referred to the aircraft as "an historical exhibit".

Worked examples

Example 1 — a first encounter with Gillespie Aeroplane

Start with the simplest possible case. Write down what Gillespie Aeroplane 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 Gillespie Aeroplane 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 Gillespie Aeroplane 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 Gillespie Aeroplane

In research: Gillespie Aeroplane 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 Gillespie Aeroplane 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: Gillespie Aeroplane is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900s United States experimental aircraft, Aircraft with fixed tricycle landing gear, High-wing aircraft, so understanding it makes those chapters shorter.
In everyday life: Look for Gillespie Aeroplane 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.
