  • Controlled flow aerial delivery system
    Patent number: 5326053
    Abstract: A tank system for an aerial liquid delivery comprises a liquid tank having an aperture for discharging liquid and a door for the aperture. The door has a seal and a door operating mechanism to remotely open the door a predetermined amount. There is an air pressure reservoir separate from the liquid tank connected to the liquid tank, and source of compressed air to pressurize the air pressure reservoir and liquid tank. The method of liquid delivery from the aircraft involves providing air pressure to a liquid tank, the tank having a door in an aperture for discharging liquid. The pressure provided to the tank before and during liquid discharge from the tank controls the flow of liquid discharging through the aperture.
