  • Patent number: 7178761
    Abstract: A container apparatus for an object to be dropped, which contains an object to be dropped functioning as a point marker or a hydrographic conditions measuring device or the like and is dropped by a transport airplane such as an aircraft flying in the air to a water surface of sea, lake or the like, or to land or the like. The container apparatus follows a substantially uniform trajectory after being dropped by the transport airplane, and after being dropped, reduces the flight speed thereof to a fixed speed, to release the object to be dropped housed therein.
    Type: Grant
    Filed: April 7, 2003
    Date of Patent: February 20, 2007
    Assignee: Japan Aircraft Manufacturing Co., Ltd.
    Inventors: Shigeru Wada, Saburo Ohashi, Shigeki Akamatsu

  • Patent number: 6814638
    Abstract: An airdrop type buoy apparatus, which is dropped by a flight vehicle, such as aircraft, that is flying in the air, to a water surface of sea or lake to be floated as a marker, a hydrographic conditions measuring device or the like, for flexibly coping with a shock at the time of landing on the water to absorb the landing shock on a balloon and also suppressing the rise of an inner pressure of the balloon so that the balloon is hardly to burst.
