Northrop X-21
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. Although useful testing was accomplished the extensive maintenance of the intricate laminar-flow system caused the end of the program.
Die Northrop X-21A war ein amerikanisches Experimentalflugzeug. Mit ihr sollten Möglichkeiten untersucht werden, die Grenzschichtströmung an einer Tragfläche zu beeinflussen, um den Luftwiderstand zu verringern und somit die Reichweite zu erhöhen.1
