  • Fluid loading system
    Patent number: 6874734
    Abstract: A pump system for loading fluid into a tank onboard a translating aircraft includes a substantially rigid tube member having a diving device on the distal end of the tube member. A strut structure may also be provided on a front face of the tube member. In use, the tube member is directed rearward relative to the translating aircraft so that splashing of fluid onto the underside of the aircraft is substantially avoided.
