Aircraft design: Increasing access to capabilities

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: Preparation

Describe

Organization. A team of designers is tasked to design an extended version of an aircraft. The team consists of senior designers and junior designers. When confronted with new design issues, junior designers tend to invent new solutions, whereas senior designers tend to develop solutions with a higher chance of regulatory compliance. The latter is a requirement for an aircraft to be allowed onto the market.

Environmental factors. Competition with other aircraft manufacturers.

Challenge. Less access to the capabilities of senior designers results in a lower chance of regulatory compliance.

Formulate

Goal. Increase business performance.

Objective. Increase access to capabilities of senior designers for designing an extended version of an aircraft faster.

Benefit. Shorter time to market.

Estimate

Worthwhile.
