Cobham 905E Refuelling Pod

摘要

The 905E under-wing air-refuelling pod is digitally controlled from the air-refuelling console located in the flight deck and uses an electrically operated hose drum unit. The pair of under-wing pods fitted to a KC-30 allows simultaneous hose and drogue refuelling at a wide range of air speeds. Fuel comes into the pod from the pumps onboard the aircraft through the fuel inlet at approximately 20psi (137kPa) and into a centrifugal pump driven by a ram air turbine. Variable blades within the turbine ramp up power to meet the fuel demand of the receiver aircraft. Rated at 50hp, the pump is able to generate a colossal amount of energy and boost the pressure up to 150psi (1,034kPa) forcing the fuel through a series of valves and into the centre of the drum.
