METHOD OF CONTROL OVER PROPELLANT FLUID COMPONENTS SURFACE LEVEL IN CARRIER ROCKET TANKS AND SYSTEM TO THIS END Russian patent published in 2014 - IPC G01F23/00 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering and can be used in control over the level of liquid propellant components in carrier rocket fuel tanks. FM signals of electromagnetic wave radiator are used to influence the propellant components surface. Reflected wave is recorded by recorder of signals reflected from fluid surface to transmit actual level via one channel to ground filling control system at prelaunch preparation and, via another channel, to onboard system of propellant in-flight control for continuous control purposes. Note here that fluid component level gages are composed by electromagnetic wave radiators, receiver of reflected wave recorder and level computer. Note also that radiator, recorder receiver and level computer are integrated in one tight case. Waveguide is arranged parallel with tank lengthwise axis.

EFFECT: higher accuracy of control and power characteristics of rocket carrier.
