Active center of gravity control can transfer fuel among many fuselage fuel tanks to effectively optimize aircraft center of gravity and gain the potential economic performance benefits. In-flight possible failures in the fuel system may generate direct influences on aircraft center of gravity control. The aim of this article is to investigate the influence of partial fuel transfer line leak on the...
Aircraft center of gravity control is an important technology to gain potential performance benefits. In-flight center of gravity control is usually based on a fuel transfer system which enables fuel to be transferred among fuselage fuel tanks and then adjust aircraft center of gravity. The aim of this article is to systematically investigate the influences of partial fuel pump failures on the CG...
Structural damage will cause a sudden variation of aircraft's quality, center of gravity and aerodynamic characteristics, as well as the destruction of longitudinal symmetry, thus bringing strong coupling. These pose serious threat to flight security. The present paper studies a kind of damaged aircrafts by presenting the nonlinear 6-DOF model of structural damaged aircraft and analyzing its dynamic...
Large scale variations in the mass or center of gravity (C.G.) pose serious problems for the control of aircraft in situations as heavy load airdrop on cargo aircraft, the airliners which employ the active C.G. control technology, aircraft with structural damages during the flight. To solve the problem of attitude control of such aircraft, a general model for the aircraft is established and a disturbance...
