The machines our world relies on were once designed with whatever tools designers had — sketches, plans, slide rulers, and sometimes, just good old-fashioned guesswork.
Often, it wasn’t until something was actually built that designers could see if it actually worked as they had intended.
Advances in technologies, such as modelling and computer-aided design, helped creators get closer to reality with their designs, but an extensive testing and redesign phase was required for prototypes to pick up any issues before production began.
This could be a lengthy process, holding up advances in technology or technique for years until flaws were ironed out.
But the United States Air Force and the aircraft manufacturer Boeing have just changed the game completely, designing and testing a new jet trainer aircraft to operational level using just computer modelling and simulation.
