Study Notes

  • Aircraft have evolved greatly over the last century.
  • Developments in aeronautical engineering are divided into aerodynamics, power plant engineering, control/navigation, airframe engineering, and structural design.
  • Power plants have gone through two major developments: the light yet powerful engine system and the jet engine.
  • The biplane construction with wire bracing was the most notable feature of aircraft construction for some years.
  • The biplane era lasted until the 1930s when metal became the prime aerospace material.
  • The "Warren Girder" design was a structure that featured 4 horizontal longerons supported by vertical struts and wire bracing.
  • The "Warren Girder" principle was copied to the internal framework of monoplane wings.
  • Early designs were far from optimized, characterizing the transition period between wire-frame structures and semi-monocoque structures.
  • Wood was used for its high specific strength and stiffness in early aircraft construction.
  • The composite era may induce further leaps in structural design.
