Abstract: Disclosed is sectional aerial refueling apparatus including a high capacity nozzle unit and a high capacity receptacle unit into which the nozzle is insertable. The probe-like forward end of the nozzle also is insertable into a prior art-type, low capacity receptacle. The nozzle has an inner fuel passage terminating at a port in its front end and an outer fuel passage extending through the side of the nozzle and terminating there in an outer port. The inner and outer fuel passages are normally closed by independently operable poppet valves which remain closed until the nozzle is inserted into a receptacle. The high capacity receptacle includes inner and outer fuel passages which in turn respectively terminate in inner and outer ports. The latter fuel passages are normally closed by independently operable poppet valves which remain closed until the nozzle and the receptacle are engaged.
