The U.S. Bureau of Labor Statistics identifies analytical, communication, mathematical, interpersonal and problem-solving abilities among important qualities for aerospace engineers.
What Does an Aerospace Engineer Do on a Typical Project?
Consider the development of a new aircraft.
An aerospace engineer may begin by studying the design requirements and determining the expected performance of the aircraft.
The engineer may then work on aerodynamic calculations, structural analysis, propulsion requirements and computer simulations.
After the initial design is developed, prototypes or components may be tested.
If testing identifies a problem, the engineer analyzes the results, modifies the design and conducts additional testing.
This cycle can continue until the design meets the required performance and engineering criteria.
Therefore, aerospace engineering is not simply about drawing airplanes. It involves a continuous process of design, analysis, testing, problem-solving and improvement.
