More environmentally friendly aircraft designs, particularly with regard to noise, was a Technology for a Quieter America (TQA) workshop hosted by the National Academy of Engineering (NAE) held in May 2017. This workshop titled "Commercial Aviation: A New Era", centered on the importance of commercial aviation to the U.S. economy, and what it will take for the U.S. to maintain global leadership in the aviation sector, including a forward-looking topic on more environmentally friendly aircraft designs. A principal focus of the workshop was the necessary step-changes in aircraft engineering technology that must be addressed with the development and testing of flight demonstrators together with significantly increased funding of public-private partnerships. Government agencies which participated included NASA, the Federal Aviation Administration, and the Department of Housing and Urban Development (HUD). There was also substantial participation from the aviation industry, airports, airlines, non-government organizations and academia.

Developmental Dynamics

The importance of studying developmental dynamics of global aircraft pool is unquestionable: this knowledge allows a substantive analysis of the history of development of aircraft engineering. At the same time, introducing for consideration some a priori notions such as e. g. “aircraft generations” allows to more fully demonstrate an interrelated development (co-evolution) of aircrafts and social institutions. This article considers as an example of co-evolution the opposition between jet fighter parks of the Warsaw Pact countries and NATO in 1954–1989. The dynamics of the development of jet fighter parks are examined and the causes of some of its characteristics are explained. Thus, it is shown that the Cold War as an opposition of two political and military alliances has been spurring the quantitative and qualitative development of fighter aircrafts. The end of the Cold War was one of the factors that slowed down the development of fighters. The results of this works clearly demonstrate that the development of aircrafts is inseparable from global social processes.

Retardation Efficiency of Shock-Absorber and Arrester Gear

The complexity of much of the mechanical gear used for shock absorption and arresting in aircraft engineering is apt to obscure some of the broad generalizations that may be deduced from the elementary principles of classical mechanics. More particularly does this apply to the distance required to arrest the motion of an aircraft or falling body when the retarding force must not exceed a specified value. This note merely presents some more or less self-evident truths which may be of some value in dealing with new landing and arrester problems.
