Hans G. Hornung

Hans G. Hornung is a engineering 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 Hans G. Hornung rather than just read about it. In short: Hans G. Hornung is an emeritus C.

Key takeaways

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

Reference excerpt

Hans G. Hornung is an emeritus C. L. "Kelly" Johnson Professor of Aeronautics and former Director of the Guggenheim Aeronautical Laboratory of the California Institute of Technology (GALCIT). He received his bachelor (1960) and master (1962) degrees from the University of Melbourne and his Ph.D. degree (1965) in Aeronautics from Imperial College, London. He worked in the Aeronautical Research Laboratories, Melbourne (1962–63, and 1965–1967), and in the Physics Department of the Australian National University (1967–1980), with a sabbatical year as a Humboldt Fellow in Darmstadt, Germany, 1974. In 1980 he accepted an offer to head the Institute for Experimental Fluid Mechanics of the DLR in Göttingen, Germany. He left Germany in 1987 to serve as the director of GALCIT. During his time at GALCIT he oversaw the construction of three large facilities: the T5 hypervelocity shock tunnel, the John Lucas Adaptive-Wall Wind Tunnel, and a supersonic Ludwieg tube. He has made contributions in gas dynamics, notably Mach reflection and effects of dissociation, in separated flows, and in wind tunnel technology. He was elected as a foreign member to the Royal Swedish Academy of Engineering Sciences in 1991. In 1997, Hornung was elected a member of the National Academy of Engineering for contributions to hypersonics and aerodynamics.

Worked examples

Example 1 — a first encounter with Hans G. Hornung

Start with the simplest possible case. Write down what Hans G. Hornung claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Hans G. Hornung 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 Hans G. Hornung 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 Hans G. Hornung

In research: Hans G. Hornung appears in engineering 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 Hans G. Hornung 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: Hans G. Hornung is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 21st-century American engineers, Academic staff of Technische Universität Darmstadt, so understanding it makes those chapters shorter.
In everyday life: Look for Hans G. Hornung 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.
