Launch tube and method of launching flying object

A method of launching a flying object, the method comprising:

• maintaining an attitude of the flying object by making a plurality of rails and a plurality of guides contact the flying object, when the flying object is launched from a launch tube;
• and
• evacuating at least a first of the plurality of guides from a region of movement of the flying object when the flying object moves to leave the plurality of guides,
• wherein:
• the plurality of rails are fixed on an inner wall of the launch tube;
• the plurality of guides are on the inner wall of the launch tube;
• the first of the plurality of guides includes a supporter configured to contact the flying object when guiding the flying object, an arm configured to support the supporter and protrude from the inner wall of the launch tube, and a biasing device configured to rotatably support the arm;
• the maintaining the attitude of the flying object includes biasing, by the biasing device, the arm in a first direction to push the supporter against the flying object;
• the evacuating at least the first of the plurality of guides from the region of movement of the flying object includes rotating, by the biasing device, the arm in the first direction and moving the supporter toward the inner wall of the launch tube;
• and
• the moving the supporter toward the inner wall of the launch tube includes moving the supporter from a first position in which the supporter contacts the flying object through a second position which is further from the inner wall of the launch tube in a second direction than the first position, the second direction extending from the inner wall of the launch tube to the flying object.

A launch tube comprising:

• a tube configured to store a flying object;
• a plurality of rails fixed on an inner wall of the tube and configured to contact the flying object;
• and
• a plurality of guides on the inner wall of the tube,
• wherein:
• a first of the plurality of guides includes a supporter configured to contact the flying object, an arm configured to support the supporter and protrude from the inner wall of the tube, and a biasing device configured to rotatably support the arm;
• the biasing device is configured to bias the arm in a first direction to push the supporter against the flying object, when the supporter contacts the flying object;
• the biasing device is configured to rotate the arm in the first direction to move the supporter toward the inner wall of the tube, when the flying object leaves the supporter;
• and
• the supporter is configured to move toward the inner wall of the tube from a first position in which the supporter contacts the flying object through a second position which is further from the inner wall of the tube in a second direction than the first position, the second direction extending from the inner wall of the tube to the flying object.
