The Combat Talon was initially developed between December 1964 and January 1967 by Lockheed Air Services (LAS) at Ontario, California, as the result of a study by Big Safari, the USAF’s program office responsible for modification and sustainment of special mission aircraft. From it two highly classified test bed aircraft (originally serial no. 64-0506 and -0507, but with all numbers “sanitized” from the aircraft), were assigned to Project Thin Slice to develop a low level clandestine penetration aircraft suitable for Special Forces operations in Southeast Asia. In 1964 Lockheed had modified six C-123B Providers for “unconventional warfare” under Project Duck…

The Lun-class ekranoplan (NATO reporting name Duck) was a ground effect aircraft designed by Rostislav Evgenievich Alexeev and used by the Soviet and Russian navies from 1987 to sometime in the late 1990s. It flew using the extra lift generated by the effect of its large wings when close to the surface of the water – about four metres or less. Lun was one of the largest seaplanes ever built, with a length of 73 m (240 ft), rivalling the Hughes H-4 Hercules (“The Spruce Goose”) and many jumbo jets. The name Lun comes from the Russian for harrier. (Source:…
Download Quieting the Boom: The Shaped Sonic Boom Demonstrator and the Quest for Quiet Supersonic Flight [401 Pages, 5.5MB] By Lawrence R. Benson On a hot and humid July day in 2003, a pair of small supersonic jet airplanes took off together from Cecil Field, a former naval air station on the eastern edge of Jacksonville, FL. Even though the Northrop Corporation had built both planes based on a common design, it was hard at first glance to tell that the two aircraft flying side by side were so closely related. One was a sleek T-38 Talon, a two-seat aircraft that has…
Introduction The NASA AD-1 was both an aircraft and an associated flight test program conducted between 1979 and 1982 at the NASA Dryden Flight Research Center, Edwards California, which successfully demonstrated an aircraft wing that could be pivoted obliquely from zero to 60 degrees during flight. The unique oblique wing was demonstrated on a small, subsonic jet-powered research aircraft called the AD-1 (Ames Dryden -1). The aircraft was flown 79 times during the research program, which evaluated the basic pivot-wing concept and gathered information on handling qualities and aerodynamics at various speeds and degrees of pivot. Thinking Obliquely: Robert…
The VZ-9-AV Avrocar (official designation but often listed as VZ-9) was a Canadian VTOL aircraft developed by Avro Aircraft Ltd. as part of a secret U.S. military project carried out in the early years of the Cold War. The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single “turborotor” blowing exhaust out the rim of the disk-shaped aircraft to provide anticipated VTOL-like performance. In the air, it would have resembled a flying saucer. Two prototypes were built as “proof-of-concept” test vehicles for a more advanced USAF fighter and also for a U.S. Army tactical…
