Aircraft design

Aircraft design

The design of a series aircraft is based on that of a predecessor: a prototype or another series aircraft. This article describes a scientific case study of how a design team can design a series aircraft more quickly.

Service

Name. Series aircraft design.

Design object. Aircraft similar to other aircraft identified by the same grouping key.

Specifics. Design a variation of aircraft identified by the same grouping key.

Situation

Description. A team of designers is tasked to design a series aircraft. The team consists of senior designers and junior designers.

Critical success factors. Junior designers slow down whenever there are no senior designers looking over their shoulders or sparring with them.

Current position. The service is:

  • Valuable.
  • Not rare.
  • Inimitable.
  • Not sufficiently organized.

  3. Reduce time waste in the design process.
Formulating the problem

Problem

Question. How can junior designers learn to design a series aircraft as senior designers do?

Issue. Senior designers are not aware of their way of working.

Prognosis. Favourable: there are possibilities to do something about it.

Advice to upgrade to leading aircraft design

Devising a concept

Concept

Question. How can junior designers learn to design a series aircraft as senior designers do?

Idea. Learn how to use design rationale while designing.

Developing a solution

Solution

Idea. Learn how to use design rationale while designing.

Action.

  1. Find out how senior designers retrieve and reuse design rationale of aircraft identified by the same grouping key.
  2. Find out how senior designers revise and retain design rationale of aircraft while designing.
  3. Train junior designers on how to use design rationale while designing.
