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 efficiently.

Aircraft design.

Aircraft design: Preparation

Analyse

Organization. A team of designers is tasked to design a series aircraft. The team consists of senior designers and junior designers. When confronted with design issues, junior designers tend to slow down if no senior designers are looking over their shoulders or sparring with them.

Environmental factors. Competition with other aircraft manufacturers.

Issues. Less access to the capabilities of senior designers leads to more time and effort to resolve a design issue.

State

Goal. Increase performance.

Objective. Increase access to capabilities for designing a series aircraft.

Benefits. Shorter design lead time.

Identify

  • Deliver a design service:
    • Design a new aircraft in an existing series [implicit].
    • Retrieve the design rationale of another aircraft in the same series [implicit].
    • Reuse the design rationale of another aircraft in the same series [implicit].
    • Revise the design rationale of aircraft [implicit].
    • Retain the design rationale of aircraft [implicit].

Compare

  • Organizational strategy:
    • Design a new aircraft in an existing series.
    • Retrieve the design rationale of another aircraft in the same series.
    • Reuse the design rationale of another aircraft in the same series.
    • Revise the design rationale of aircraft.
    • Retain the design rationale of aircraft.

Aircraft design: Valuation

Appraise

Aircraft design: Transition

Scale

  • System. Elicit and include as instructions in the standard operating procedure:
    • Deliver a design service:
      • Retrieve the design rationale of another aircraft in the same series.
      • Reuse the design rationale of another aircraft in the same series.
      • Revise the design rationale of aircraft.
      • Retain the design rationale of aircraft.
  • Skills. Train junior designers in the standard operating procedure.
