Abstract

The chapter presents an overview of jet airliner evolution after the Second World War. It illustrates that modern airliner general arrangement is based on early concepts, namely the Boeing B-47 bomber and the B-707 airliner of the 1950s. The most significant economical and environmental improvements were achieved in gas turbine engine technology, culminating in the modern very efficient and reliable high-bypass ratio turbofan. A concise geometrical description of the aircraft's main components is followed by a brief description of major technological breakthroughs over the past decades. Subjects treated are flight control, avionics, structural design, and materials. The continuously improving energy efficiency is illustrated by a data collection showing that the seat-km per liter of gas turbine fuel produced by modern jet airliners exceeds the performance of mid-sized cars, even though their cruising speed is an order of magnitude higher.
