Coordinating Aircraft-Engine Design and Production 390132

IT is necessary to develop designs that can be manufactured readily to keep down costs. This policy benefits the industry generally, and it is also necessary to meet domestic and foreign competition.
Close attention to the following items is necessary to produce and maintain satisfactory production designs:
  1. 1.
    Carefully developed design and test programs are essential to develop advanced engines and details by orderly and logical processes.
  2. 2.
    Standardized engineering and drafting practices are a necessary part of any engineering organization to maintain drawing consistency.
  3. 3.
    Close cooperation between production and engineering departments, starting with the original design and manufacture of experimental parts, is particularly important.
  4. 4.
    The utilization of developed units and parts on new models when practicable. The desirability of reducing the total quantity of different parts made is evident to facilitate manufacture and servicing.
  5. 5.
    Consideration of suggested changes from all sources to simplify production and reduce costs.
  6. 6.
    Adequate quality and finish control. Finishes usually are controlled by samples, but the development of instruments to measure finish accuracy will assist materially in establishing a more precise control.
