    The electronic flight control system (EFCS) on the A, like its predecessors the A, A, A, and A, contains fly-by-wire control laws that can result in neutral lateral-directional static stability; therefore, the conventional requirements in the regulations are not met.

Tails of an aeroservoelastic interaction experienced in flight by the XA forward-swept wing airplane. A Hz canard pitch mode response was aliased by the digital sampling rate in the canard position feed-back loop of the flight control system, resulting in a Hz signal being commanded to the longitudinal control surfaces.

The electronic flight control system uses the pitch control function of the canard foreplane to create artificial static and dynamic stability. A benefit obtainable from a control-canard is the correction of pitch-up during An in-flight interaction of the X-29A canard and flight control system book wingtip stall.

An all-moving canard capable of a significant nose-down deflection can be used to counteract the pitch-up. In this study, the effects of canard–wing interference on the flight characteristics of a conceptual civilian transonic cruiser were examined.

The X is a canard delta, a delta wing aircraft which uses canard foreplanes for primary pitch control, with secondary thrust-vectoring control. The canard delta had earlier been used on the Saab Viggen strike fighter, and has since become common on fighters such as the Eurofighter Typhoon, Dassault Rafale and Gripen which were all designed Manufacturer: Rockwell / Messerschmitt-Bölkow-Blohm.

Abstract. Despite the NASA X program’s outstanding success in developing and operating the first manned hypersonic research platform, the program suffered a fatal accident on Novemwhen X, the only aircraft outfitted with advanced pilot displays and an adaptive flight control system, was lost after entering uncontrolled flight at an altitude offeet and a Cited by: 1.

Most unconventional control systems involve some form of thrust vector control (TVC) or jet interaction (JI). We have now introduced four major categories of missile flight control systems--tail control, canard control, wing control, and unconventional control--so.
