BRAT Option B201M

Missile Test System


The BRAT Option B201M is a general purpose missile test system utilizing Commercial-Off-The-Shelf (COTS) equipment in a modular design. The tester consists of two rack consoles to test pneumatic and electrical parameters respectively. The reconfigurable consoles allow easy access to all of the modules and room for expansion/
reconfiguring. The pneumatic console provides eight lines to the two independent gas supplies. The electronic console interface provides up to 450 pins of signal I/O and switching capability and 600 pins of cable testing capability.

State-of-the-Art Technology

The BRAT features VXI instrument-on-a-card and modular technologies to provide complex testing capabilities in a compact workstation. The pneumatic pressure and flow rates are controlled by a real time computer system that obtains pressure, temperature, and flow rates and adjusts valves automatically to obtain the desired settings.

Electronic Valve and Servo Motor Testing

The electronic console contains a Driver Simulator Module that provides precision drive signals that are monitored to provide measurement capabilities of servo motor slew rate, motor spin up time, and valve open and close times.

Ordnance Initiator Device Testing

The electronic console contains circuitry to safely test Ordnance Initiator Devices by using controlled currents.

Precision Pneumatic Pressure and Flow Sources

The pneumatic console uses Helium and Nitrogen gas sources to supply a pressure or flow through the gas interface lines.
