Embraer Tests Composite Wing for New Tech Demonstration Platform

Embraer has completed the initial structural fatigue tests on the composite wing for its New Technologies Demonstration Platform (PDNT), a project supported by Brazil’s Ministry of Science, Technology and Innovation (MCTI).

The innovation project, funded by the National Development, Scientific and Technological Funding (FNDCT) and managed by Finep, focuses on research and development of low and medium Technology Readiness Levels (TRL). Co-executors include Alltec, Equatorial, Motora, and TecCer.

The first phase of testing involved developing new processes for analysis in ground test benches (RIGs). The wing’s reference model, incorporating new production techniques, was subjected to progressive loads exceeding 200% of the expected limit.

The static loading test took place at ACS Aviation in São José dos Campos, Brazil, validating innovative materials and methodologies. Next, Embraer plans to manufacture the fuselage and empennage for the flying laboratory.

The project involves several Brazilian Institutes of Science and Technology, including the Technological Institute of Aeronautics (ITA), the Mauá Institute of Technology (IMT), the Institute of Technological Research (IPT), and the University of São Paulo’s School of Engineering of São Carlos.
