A variable braking system for a cargo handling system, the variable braking system comprising:
- a tray comprising a first rail and a second rail;
- and
- a brake roller assembly, comprising:
- a shaft coupled to the first rail and the second rail;
- a roller cylinder disposed radially outward of the shaft and between the first rail and the second rail, the roller cylinder configured to rotate relative to the shaft, the roller cylinder and the shaft partially defining a cavity therebetween;
- and
- a fluid disposed in the cavity, the fluid configured to change viscosity to vary a braking force of the brake roller assembly.
A control system for a cargo handling system, the control system comprising:
- a voltage regulator;
- a load cell coupled to a tray of the cargo handling system;
- a brake roller assembly having a plurality of electrodes disposed therein;
- a controller coupled to the load cell and the plurality of electrodes, the controller operable to:
- receive, via the load cell, a weight measurement of a cargo;
- determine a desired viscosity based on the weight measurement and a desired braking force;
- and
- command the voltage regulator to supply a desired voltage based on the desired viscosity to the plurality of electrodes.
