The aircraft design process is the engineering design process by which aircraft aircraft performance and design john anderson pdf free download designed. These depend on many factors such as customer and manufacturer demand, safety protocols, physical and economic constraints etc.
For some types of aircraft the design process is regulated by national airworthiness authorities. This article deals with powered aircraft such as airplanes and helicopter designs.
Aircraft design is a compromise between many competing factors and constraints and accounts for existing designs and market requirements to produce the best aircraft. The design process starts with the aircraft’s intended purpose. Commercial airliners are designed for carrying a passenger or cargo payload, long range and greater fuel efficiency where as fighter jets are designed to perform high speed maneuvers and provide close support to ground troops. The purpose may be to fit a specific requirement, e.
Another important factor that influences the design of the aircraft are the regulations put forth by national airworthiness authorities. Airports may also impose limits on aircraft, for instance, the maximum wingspan allowed for a conventional aircraft is 80 m to prevent collisions between aircraft while taxiing.
Budget limitations, market requirements and competition set constraints on the design process and comprise the non-technical influences on aircraft design along with environmental factors. Competition leads to companies striving for better efficiency in the design without compromising performance and incorporating new techniques and technology. An increase in the number of aircraft also means greater carbon emissions. Environmental scientists have voiced concern over the main kinds of pollution associated with aircraft, mainly noise and emissions.
