Originally designed and built as a demonstration model for NASA and the USAF, the Grumman X-29 fighter is more maneuverable and less expensive to operate than any other conventional aircraft. Describes the origins of the forward-swept wing concept and the technological developments that revived this once-ignored wing plan. Includes complete details of the X-29¹s systems and construction, including: digital fly-by-wire flight control; the power plant engine; the lightweight space-age materials; the NASA-developed super critical wing; and the three-surface pitch control. Over 100 b/w and color line drawings and photos.
