Different company plants throughout the country, t work on an aircraft drawing as it develops from initial shapes to a final, dmensioned, eplained, prt. Taditionally, tese drawings had always been prepared manually using drafting tables and conveyed between plants via company inter-office mail. B the introduction of early computerized drawing techniques and the accessibility of quality Interactive Computer Graphic (ICG) systems BCAC management decided to replace, bth the manual drafting and inter-office mailing of aircraft design drawings. Tis was the beginning of the Computer Aided Design/Computer Assisted Manufacturing 1981).
Te design that uses new technology with care for improved performance and costs and without exposing undue program risks is of vital important. Tis needs ever-increasing confidence on advances in computational fluid dynamics for new aerodynamic designs of airframes and engines. Ative controls and smart structures will be used to develop performance, rduce weight and increase fatigue life. Wth the purpose to reduce risks and uncertainties, tchnology campaigner programs will be widely used to prove advanced features in airframes and engines by showing expected gains are attainable and manufacturer must also adopt new business processes to shorten cycle times for design and manufacture, wich reduce their cost and also give earlier access to market and increase sales.
A integrated product development approach involving design-build teams, were engineering, mnufacturing and procurement/finance work closely together to achieve the best design for cost and performance, sems most competent. Te result is often a varied team with several multinational partners and suppliers. Tsks become widely dispersed, ad this requires highly effective electronic communications for the exchange of up-to-date information, uing data for technical definitions and electronic data interchange for forms, ec This also points to the need for well-suited three-dimensional computer automated design (3-D CAD) systems, ad common data bases for design, mnufacturing, pocurement and finance.
Mltidisciplinary design and optimization explains an integrated set of computer programs that properly size and optimize the structural design of aircraft or engines to meet design necessities, wile controlled by factors such as weight, cst, mterial properties and vibration or flutter. ..
