Aircraft Emergency Fuel Boost Pump
Many small propeller-driven aircraft benefit from a two-speed pump that maintains fuel pressure while cruising, but boosts fuel delivery for takeoff and landing.
One aircraft pump manufacturer consulted Allied Motion seeking such a two-speed fuel pump motor solution. Allied’s design team engineered a unique solution in which a standard Endurance brush DC motor was modified to accept two different voltages, enabling our customer to supply a reliable two-speed pump that doesn’t stall, as was the case with some other motors they tried previously.
Auxiliary Unit Fuel Pump
In the control of gas turbine engines used in aircraft auxiliary power units (APU) that must operate at tens-of-thousands of rpm, fuel pump frequency response and reliability are two key design parameters.
Allied Motion engineers, working closely with the turbine manufacturer of this gerotor-type fuel pump, optimized the parameters of the pump motor, an Allied Motion Megaflux frameless brushless torque motor, resulting in an economical solution that exceeded performance and reliability goals.
