Model BNP-18-000 Coolant Pump in the US Marine Corps' Shadow Reconnaissance, Surveillance & Targeting Vehicle (RST-V)

BN designed and produced a prototype dual-fluid electronics cooling pump for the US Marine Corps’ Shadow Reconnaissance, Surveillance & Targeting Vehicle (RST-V). The vehicle is equipped with a tightly packed array of communications hardware, optical and thermal sensors, and range finding equipment. This complex electronics package requires ethylene-glycol and oil coolants. In response to this requirement, Barber-Nichols designed a single pump with two impellers which minimizes weight, space, and electrical power consumption.
