The X-29A is 35% statically unstable longitudinally and is controllable only through the use of an advanced, digital fly-by-wire flight control system (FCS). The predicted aerodynamic advantages of the X-29A configuration are what make the risk of deve-loping and flying a new airplane worthwhile. It is, therefore, imperative that the wing ...
1 Ιουν 1994 · This paper describes the primary flight control system and significant modifications made to this system, flight test techniques used during envelope expansion, and results for the low- and...
The X-29A No. 2 airplane was used primarily to examine high-AOA characteristics, but was also used to study the stability margins of the lateral–directional axes using multi-input–multi-output (MIMO) techniques at low-AOA conditions. 4.1 Description of the Flight Control System The X-29A airplane is controlled through a triplex fly-by-wire ...
5 Νοε 2015 · The fighter-size X-29 also explored the use of advanced composites in aircraft construction; variable camber wing surfaces; the unique forward-swept wing and its thin supercritical airfoil; strake flaps; close-coupled canards; and a computerized fly-by-wire flight control system to maintain control of the otherwise unstable aircraft.
Two X-29 aircraft, featuring one of the more unusual designs in aviation history, were flown at NASA Ames-Dryden Flight Research Facility (now Arm-strong Flight Research Center) at Edwards Air Force Base, California. The demonstrators investigated advanced concepts and technologies during a multi-phased program conducted from 1984 to 1992.
In this representative conventional static wind tunnel test, a 2.7-percent scale model of the Boeing 777 airplane is mounted to a sting support system for testing at transonic speeds in the National Transonic Facility at the NASA Langley Research Center. The model contains exten-
