Acme Sierra

From Wikipedia, the free encyclopedia

The Acme S-1 Sierra was an experimental aircraft of unusual configuration built in the US in 1948 to investigate the advantages of a pusher propeller configuration. Apart from this engine installation, the aircraft was unusual in having an X-shaped tail incorporating ruddervators on the upper fins. The wing was mounted midway up the fuselage and was unswept. During the 1960s, Northrop used the aircraft as a technology demonstrator for boundary layer control concepts.
