FACILITY FOR GROSS WEIGHT CONTROL OF AIRCRAFT FUEL Russian patent published in 2009 - IPC G01G19/07 

FIELD: measuring technology.

SUBSTANCE: invention refers to aeronautical engineering and, particularly to systems of complex control of weight and centring of passenger and transport airplanes of classic scheme wherein fuel is placed in wing, while load is placed in fuselage. The facility of gross weight control of airplane fuel consists of sensors of angle of attack, Max number, altitude, interceptor's deviation angles, wing flap deviation angles, slat deviation angle, rate of list, rate of pitch and rate of yawing connected to the input of a multiplier, of a differentiator, and of a switchboard, the input of which is connected to the output of a divider. The switchboard is connected to a memory block, the input of which is connected with the output of circuit "OR", the inputs of the latter are connected to comparing blocks. Additionally the switch board is connected to a functional converter which together with the comparing block evaluates plane fuel weight and centring. Also the comparing block consists of connections with sensors of aerodynamic indices, angular motions of a plane, and rudders deviation, with the multiplier, differentiators, a subtraction circuit, an adder and a block of list moment determination.

EFFECT: upgraded validity and accuracy of fuel weight control, increased reliability and safety of flight, and improved operation characteristics of airplane.
