Aviation Technology
Innovations in engines and other aspects of aeronautical technology have made aircraft safer, quieter, and more fuel and cost efficient.

High-Bypass Turbofan Engines High-bypass turbofans have a large fan at the front of the engine that produces most of the thrust. They are more powerful, more efficient, and much quieter than conventional jet engines. Introduced on Boeing's 747 wide-body airliner in 1970, high-bypass turbofans drastically changed the economics of the airline industry by helping to lower operating costs and, therefore, fares. Smaller versions have increased the efficiency of narrow-body airliners, the most widely used type in service. |
