摘要： PROBLEM TO BE SOLVED: To give stability to an object towed by a flying airplane by shrinking the diameter of a circle against the force of an elastic means via a sleeve movable in the vertical direction to the plane of the circle as the drag is increased. SOLUTION: Blades 4, 5 are located at parallel locations where the angular moment caused by the air pressure applied to their free ends becomes equal to the angular moment in the opposite direction applied to the pivotal ends of the blades 4, 5 by the restoring force of a compressed spring 11 applied to the sleeve 6. When the speed of a towing airplane is increased, the cross sectional area generating drag is decreased. The blades 4, 5 have the minimum cross sectional area to generate the drag and form a substantially continued conical surface. The sleeve 6 is constrained not to be moved forward any more by lugs 9 colliding with the other ends of corresponding slots 10 respectively.

摘要： PURPOSE: To achieve improvement of functions where there are limitations in dimensions and weight applicable to a target in tow, expansion of uses, and increase of the efficiency of the total system. CONSTITUTION: The subject relates to a system of electric source of a target in tow and signal transmission which is equipped with a single line of cable 14 incorporated in a towline, an electric supply system which by the use of the cable 14 electric energy is supplied from a towing craft 2 to a towed target 3, a control-signal transmission system which by the use of the same cable 14 uses high frequencies from the towing craft 2 to the towed target 3, and a monitor-signal transmission system which by the use of the same cable 14 uses high frequencies differing from those in use in the control-signal transmission system referred to above contrarily from the towed target 3 to the towing craft.

摘要： PURPOSE:To permit a plurality of times of lighting by one piece of light and facilitate seeing from a direction, in which the towed body could hardly be seen as a target body so far, simply by changing the generating method of the light from explosive into a lighting device. CONSTITUTION:A commanding signal, outputted from an aeroplane 1 or a control device 2 on the ground, is received by the antenna 5 of a towed body 3a and a receiver 6 outputs a control signal based on the received signal while the control signal is supplied to a controller 7. The controller 7 controls the connecting and/or interrupting of the connection between a battery 8 and a light 9 based on the control signal to light or extinguish the light 9. Light beams, emitted from the light 9, premeate through a cover 10 and are released into space, in which the body is being towed. The towed body 3a can be utilized as a target body, providing a guiding flying body with guiding light emitted from the light 9, in such a manner.
