The widespread use of digital techniques throughout design and manufacture has led to a revolution in aircraft design. Now, a designer can create an aircraft, model its aerodynamic and mechanical characteristics, design the production components and have them manufactured on the shop floor, all within a single end-to-end digital domain.
In the 1970s, an uncrewed propeller-driven aircraft was constructed and tested at Moffett Field. [5] Known as the NASA Oblique Wing, the project pointed out a craft's unpleasant characteristics at large sweep angles. So far, only one crewed aircraft, the NASA AD-1, has been built to explore this concept.
In the 1960s and 1970s, many design studies for supersonic airliners were done and eventually two types entered service, the Soviet Tupolev Tu-144 (1968) and Anglo-French Concorde (1969). However political, environmental and economic obstacles and one fatal Concorde crash prevented them from being used to their full commercial potential.
In aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s, the term generally came to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the supersonic regime.
The NASA Oblique Wing Research Aircraft, the predecessor to the AD-1. The first known oblique wing design was the Blohm & Voss P.202, proposed by Richard Vogt in 1942. [1] The oblique wing concept was later promoted by Robert T. Jones, an aeronautical engineer at NASA's Ames Research Center, Moffett Field, California.
In the 1970s a special aviation complex was established by the Soviets at Taganrog machine-building factory to develop airborne laser technology for the Soviet military. In 1977 Beriev OKB started the design of a flying laboratory designated '1А'.
U.S. Air Force C-130 Hercules and C-141 Starlifter transports complete an airlift begun November 18 to bring relief supplies and equipment to East Pakistan after the devastating 1970 Bhola cyclone. The aircraft have delivered a total of 140 short tons (127 metric tons ) of supplies and equipment, some of them making flights of almost 10,000 ...
Although the modern theory of aerodynamic science did not emerge until the 18th century, its foundations began to emerge in ancient times. The fundamental aerodynamics continuity assumption has its origins in Aristotle's Treatise on the Heavens, although Archimedes, working in the 3rd century BC, was the first person to formally assert that a fluid could be treated as a continuum.
