According to researchers in Mechanical Engineering at Penn State University, hummingbirds have extreme aerial agility and flight forms, which is why many drones and other aerial vehicles are designed to mimic hummingbird movement. Using a novel modeling method, Professor Bo Cheng and his team of researchers gained new insights into how hummingbirds produce wing movement, which could lead to design improvements in flying robots.
“We essentially reverse-engineered the inner working of the wing musculoskeletal system — how the muscles and skeleton work in hummingbirds to flap the wings,” said first author and Penn State mechanical engineering graduate student Suyash Agrawal. “The traditional methods have mostly focused on measuring activity of a bird or insect when they are in natural flight or in an artificial environment where flight-like conditions are simulated. But most insects and, among birds specifically, hummingbirds are very small. The data that we can get from those measurements are limited.”
Penn State researchers used muscle anatomy literature, computational fluid dynamics simulation data and wing-skeletal movement information captured using micro-CT and X-ray methods to inform their model. They also used an optimization algorithm based on evolutionary strategies, known as the genetic algorithm, to calibrate the parameters of the model. According to the researchers, their approach is the first to integrate these disparate parts for biological fliers.
With this model, the researchers uncovered previously unknown principles of hummingbird wing actuation. While Cheng emphasized that the results from the optimized model are predictions that will need validation, he said that it has implications for technological development of aerial vehicles.

In the text, the term ‘reverse-engineered’ (first sentence of the second paragraph) is not referring to an industrial product, which represents a variation of its conventional meaning.
In order to delve into the basics of English phonology, it is important to establish a clear understanding of what phonology is and its scope of study. Phonology is a subfield of linguistics that focuses on the systematic study of sounds within a particular language or languages. It examines the patterns, organization, and rules governing the sounds and their usage in speech.
The scope of phonology encompasses several key aspects. Firstly, it examines the inventory of sounds in a language, identifying the distinct phonemes and their distribution within words. It also investigates the rules and patterns governing the combination and sequencing of sounds, known as phonotactics. These rules determine which sounds can appear in specific positions within words or syllables (Dodd, et al, 2003).
What is the main objective of phonology?
