NASA’s F-15 research test bed will expose the Swept Wing Laminar Flow test article to speeds up to Mach 2, matching conditions presented during wind tunnel testing at NASA’s Langley Research Center.

The Swept Wing Laminar Flow test article, integrated to the underside of a NASA F-15, will examine the effectiveness of different configurations of small dots, called distributed roughness elements, to extend smooth, laminar airflow over a wing’s depth, reducing friction drag.

Testing different configurations of distributed roughness elements on the Swept Wing Laminar Flow test article, seen suspended above, will allow NASA researchers to observe which distributions are most efficient in extending laminar flow over a supersonic aircraft’s wing.

The X-4 Bantam, a single-place, low swept-wing, semi-tailless aircraft, was designed and built by Northrop Aircraft, Inc. It had no horizontal tail surfaces and its mission was to obtain in-flight data on the stability and control of semi-tailless aircraft at high subsonic speeds.

Saturn many cloud patterns, swept along by high-speed winds, look as if they were painted on by some eager alien artist in this image from NASA Cassini spacecraft. With no real surface features to slow them down, wind speeds on Saturn can top 1,100 mph (1,800 kph), more than four times the top speeds on Earth. This view looks toward the sunlit side of the rings from about 29 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on April 4, 2014 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 752 nanometers. The view was obtained at a distance of approximately 1.1 million miles (1.8 million kilometers) from Saturn. Image scale is 68 miles (109 kilometers) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA18280

In this photograph, the C-140 JetStar is fitted with a model of a high-speed propeller. Three different designs were tested at NASA's Dryden Flight Research Facility in 1981-1982. Their swept-back blades were intended to increase the speed and fuel efficiency of turboprop aircraft. Speeds of Mach 0.8 were thought possible, while using 20 to 30 percent less fuel than standard jet engines.
