    Abstract: A non-motorized flying unit for observation according to an exemplary embodiment of the present disclosure includes: a body part which is mounted on a launcher, launched in a direction toward a preset target when the launcher operates, and falls, by its own weight, toward the ground from a position of a top dead point (TDP); a propeller unit which is coupled to the body part, and automatically generates rotational force by means of drag force applied to the body part when the body part falls so as to decrease a falling velocity of the body part; and an image capturing unit which is installed on the body part, and obtains image information in respect to the ground when the body part falls.

    Abstract: A launch canister for ejection from a submerged launch platform, the launch canister being adapted for ejection in a direction substantially along a first axis of the launch canister and comprising: an enclosure for carrying a UAV; a nose cap releasably located in a launch opening at a forward end of the launch canister; a launch mechanism for driving a UAV carried in the enclosure out of the launch canister through the launch opening in a direction substantially along said first axis; and a water surface sensor for detecting when the nose cap of the canister broaches the surface of the water; wherein the launch canister is configured to, on the water surface sensor detecting that the nose cap of the canister has broached the surface of the water, immediately release the nose cap and initiate the launch mechanism to drive a UAV carried in the enclosure out of the launch canister through the launch opening.
