The history of propulsion goes back a long way, for more than 100 years since the Wright brothers started building a simple engine with only 3-hp and one cylinder. It was a considerable feat in that era. Engineers, regardless of which era, strived for more power, longer durability and higher efficiency in the smallest and lightest designs possible. Above all that, there were costs and maintenance considerations. Advances in propulsion have been great for the past 100 years and continue to strive for even better engines.
The first engine to take flight was the piston engine. As time passed, different types of engines emerged, including today’s very popular jet engines. Jet engines have variations and today, the turbofan remains the most popular in commercial aircrafts. Even in combat aircrafts, turbofans with afterburners are also very popular. A timeline in the next section will exemplify everything more clearly in the following page.
