4
Design engineer- responsible for the general
design of the aircraft performance, and
general concept. All of which must be met
with available materials and manufacturing
processes.

Team

5
Materials engineer- specifies the
materials based on properties, cost,
size, shape, processing etc.

6
Stress engineer- analyzes/refines geometry
to ensure the material of the components are
not pushed beyond their properties.

7
Raw materials producer- supplies the
materials for the aircraft, maintains quality
control of physical properties, identifies
material and produces certifications to
accompany material, may package materials
to protect from environmental damage before
use. The materials producer may frequently
test the material or send samples for
independent verification.

Technician- performs the correct processing
according to standards, verifies certifications
accompany materials at each step. The
technician follows procedures and checks off
performed steps.
