DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a towing device,
In particular, the present invention relates to a towing device with a recovery mechanism mounted on an aircraft or the like.

[0002]

2. Description of the Related Art Conventionally, a vehicle is mounted on a flying object such as an aircraft,
BACKGROUND ART A towed body towed by an aircraft or the like and a tow line (wire) is known. This type of towing body is used, for example, as a target and various tests are performed during towing. After the test, the towing body is separated from the aircraft, dropped into the sea, and then recovered.

[0003] Since the towed body must be collected after dropping, it is devised to float on the sea surface after dropping.
For example, as shown in FIG. 3 (A), urethane foam 7 is put inside the towing body 2, or as shown in FIG. 3 (B), the inside of the towing body 2 is hermetically sealed using an O-ring or a sealing material. The structure (hollow structure) 8 makes the apparent specific gravity smaller than that of water. Further, as shown in FIG. 3 (C), a special floating device 9 is provided for inflating a floating tool such as a floating bag after landing.

[0004]

In the conventional device, it is necessary to make the apparent specific gravity smaller than water or to mount a special floating device in order to make the towing body float.
Therefore, there is a problem that the towing body itself becomes large. When the tow body cannot be made large, there is a problem that the test equipment mounted on the tow body must be limited (reduced in number, etc.).

[0005] The present invention has been made in view of the above problems, and has as its object to reduce the size and weight of a towed vehicle or to relax restrictions on equipment mounted on the towed vehicle.

[0006]

According to the present invention, there is provided a tow body, a tow line connected to the tow body, and a reel provided with levitation means for winding the tow line. The towing device is constituted by a connecting means for detachably connecting the reel to the flying object.

According to the towing apparatus of the present invention having the above structure, the towing body towed by the flying object is connected to the towing line, and the reel on which the towing line is wound is fixed and held on the flying object side. doing. When the tow line is disconnected from the aircraft after the test, etc., the connecting means is operated, and the tow body, tow line and reel are separated from the flying object and dropped onto the sea.
The reels float on the sea because they have floating means. At the time of recovery, a tow line from a reel floating on the sea surface,
Reach the towed body and collect all dropped objects.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing one embodiment of the present invention,
(A) is an overall view, (B) is an enlarged sectional view of a reel mounting portion.

As shown in FIG. 1A, an aircraft 1, which is a flying object, tow a tow body 2 with a tow line 3. The towing line 3 is fixed to the A section of the aircraft 1.

FIG. 1B is an enlarged cross-sectional view of a portion A shown in FIG. 1A.
Is rotatably supported by explosion bolts 6a and 6b on a holder 10, and the holder 10 is fixed to the aircraft 1. The reel 4 is a hollow float type reel having a hollow portion 4a formed at the center thereof. In addition, explosion bolt 6
Explosives are incorporated in the tips of the a and 6b (engagement portions with the reel 4) and are ignited by an electric signal from the signal line 11. When the explosion bolts 6a and 6b explode, their tips are destroyed, and the reel 4 is separated from the holder 10 and falls from the aircraft 1.

A brake plate 12 is attached to one side of the reel 4 by bolts 6b so as to rotate integrally with the reel 4, and an electromagnetic brake 5 is arranged around the brake plate 12 so as to sandwich the brake plate 12. ing.

Next, the operation of the embodiment will be described. During the flight, the towing body 2 separated from the aircraft 1
It is blown behind the aircraft 1. In the drawer portion A of the towing line 3 of the aircraft 1, when the towing line 3 is released to a predetermined length, the electromagnetic brake 5 is operated, the brake plate 12 is locked, and the rotation of the reel 4 is stopped. The towing body 2 is towed by the aircraft 1.

When the test or the like is completed and the towing body 2 is to be discarded, an electric signal is sent from the signal line 11 to cause the explosion bolt 6a,
The reel 4 is separated from the holder 10 by exploding 6b. As a result, the towing body 2 is separated from the aircraft 1 together with the towing line 3 and the reel 4 and is dumped on the sea.

As shown in FIG. 2, the separated and discarded towing body 2 and the towing line 3 sink into the sea, but the reel 4 is a closed structure having air in the hollow portion 4a. Floating on the sea because it is smaller. This reel 4
, The towing body 2, the towing line 3, and the reel 4 that have been dumped on the sea surface can be collected.

[0015]

According to the present invention, there is no need to additionally mount urethane foam and a floating device on the tow body itself, or to provide a hermetically sealed structure, and to reduce the size of the tow body or increase the number of equipment mounted on the tow body. Will be able to do it. The reason is that by providing a reel that can float on the sea surface together with the towing body and the towing line, the towing line and the towing body can be recovered from the reel floating on the sea surface.
