The left laminar flow wing section. Natural laminar flow is opposed to hybrid laminar flow artificially induced through hardware. It is difficult to industrialise a wing smooth enough to sustain the laminar flow in operation, due to having very low design and manufacturing tolerances, leading-edge retractable slats, and fasteners, that is aerodynamically robust enough, and can withstand ...
The Breakthrough Laminar Aircraft Demonstrator in Europe (BLADE) is an Airbus project within the framework to flight-test experimental laminar-flow wing sections on an A340 from September 2017. [4] Other examples of hardware that have been developed with the support of Clean Sky include:

In the latest round of their decades-long battle for dominance in commercial aircraft, Europe’s Airbus established a clear sales lead over Boeing even before the American company encountered ...
The Northrop X-21A was an experimental aircraft designed to test wings with laminar flow control. It was based on the Douglas WB-66D airframe, with the wing-mounted engines moved to the rear fuselage and making space for air compressors. The aircraft first flew on 18 April 1963 with NASA test pilot Jack Wells at the controls. [1]
NATO's top commander said on Thursday he did not believe Russia's military has deployed enough troops to make a strategic breakthrough in the region around Kharkiv in northeastern Ukraine. General ...
