UFC-3C-FMS Flight Management System

click to enlarge

The Flight Management System Module provides unique control functions for flight stability and hybrid or monopropellant liquid motor control. Based on the Cypress Programmable System on Chip (PSoC) that allows the user to program at a low level the module functions or use the built-in software for control functions. It includes a control algorithm for aerodynamic flight control surfaces with four stepper motor using an Inertial Measurement Unit (IMU) for attitude reference. It also includes an algorithm to control the flow of Nitrous Oxide or Nitrous Oxide Fuel Blend (NOSBX) into the motor with a stepper motor controlled Flow Control Valve (FCV) based on combustion chamber (thrust) or a user developed optimization program. Please see Hybrid Motor System for further details.

Additional Info
Name: UFC-3C-FMS Flight Management System Module
Description: The UFC-3-FMS supports Vertical Trajectory Stabilization (VTS) through the control of four stepper motors driven by an Inertial Measurement Unit (IMU) and oxidizer flow control into a hybrid or NOBFX motor with a fifth stepper motor on a Flow Control Valve.  It may be programmed by the user (all tools included) or configured with the built-in management software
