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.

In this study, a sodium hydroxide modified soybean protein adhesive (NSP adhesive) was prepared and mixed with phenol-formaldehyde (PF) resin in a ratio of 7:3 to form a compound adhesive (NSPF adhesive), and three-layer plywoods were prepared using the NSP adhesive and the NSPF adhesive. In order to understand the reactions between SP and PF resin during the curing process of NSPF adhesive, the SEM and FTIR spectra were employed to character the adhesives and the bonding strength of the plywoods was measured. The results showed that the bonding strength of the poplar plywood prepared with NSPF reached 1.00 MPa, and met type I plywood requirement in GB/T 17657-1999. There was new absorption peak appear at 1390 cm-1 in the FTIR spectra of NSPF adhesive, indicating that there were -NHCH2- structures generate in NSPF during the curing process in this research.

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.
