JPH0237098A - Multi-color smoke fuming device for aircraft - Google Patents

Abstract

PURPOSE:To enable to have mottled smoke of multi-colors fumed by operating a control switch for switching valves connected with respective fuming oil tanks with different pigments mixed, and disposed at plural passages comprising a smoke nozzle opening into engine exhaust. CONSTITUTION:When a valve 5A is opened and a valve 5B is closed through a controller 10 by means of a control switch 8, the fuming oil 2A in a fuming oil tank 1A is injected into the exhaust pipe 13 of a jet engine 4 from a smoke nozzle 9 through a passage 11A, the valve 5A and a smoke nozzle tube 9 by means of a pump 3A. The fuming oil 2A is carburetted by exhaust air 6, and smoke 12 of the colors corresponding to the pigments mixed in the fuming oil 2A is generated. When the valves 5A, 5B are switched after the appropriate time elapsed through the controller 10 reoperating the control switch 8, the fuming oil 2B in the fuming oil tank 1B is injected into the exhaust pipe 13, and the smoke 12 of different colors is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a multicolor smoke generator for aircraft, which is capable of emitting multicolored smoke such as a spot-shaped smoke.

[Conventional technology]

As shown in FIGS. 5 and 6, the conventional smoke generating device for aircraft includes a smoking oil tank O1 in the aircraft 014, and the smoking oil 02 mixed with the pigment in the same effect tank 01 is transferred to the tank 01. The oil is injected from the smoke nozzle O9 into the engine exhaust 06 in the exhaust pipe 013 of the jet engine 04 through the valve 05 operated by the operation switch 08 by the pump 03 inside, and the smoke is generated by vaporizing the smoke oil 02 by the exhaust gas 06. One color 012 corresponding to pigment mixed in oil
is designed to occur.

(Problems to be Solved by the Invention) As described above, in the conventional technology, only one color of smoke can be generated due to the pigment mixed in the fuming oil, and therefore the display effect is poor.

The present invention aims to provide a multi-colored smoke generating device for an aircraft that generates multi-colored spotted smoke.

[Means for Solving the Problems] The multicolored aircraft smoke generator of the present invention accommodates smoke oils each containing a mixture of different pigments. ! The engine includes several smoking oil tanks, a plurality of passages connected to each smoking oil tank and having smoke nozzles that open into the engine exhaust gas, and a controller that opens and closes valves provided in the passages.

[Operation] In the present invention, the buried oil in a specific smoking oil tank is injected into the engine exhaust by opening and closing the valve by the controller, and the smoking oil is vaporized and converted into pigment mixed in the smoking oil. You can get the corresponding smoke.

By appropriately switching the valves opened by the controller, multicolored smoke is generated.

Further, by appropriately selecting the valves to be opened, smoke of a desired color can be produced.

〔Example〕

A first embodiment of the present invention will be described with reference to FIGS. 1 and 2.

IA and IB are fuming oils 2 with different pigments mixed together.
It is a smoking oil tank that accommodates oil pumps A and 2B and also has built-in pumps 3A and 3B, and the tanks IA and IB have passages 11A and II that are provided with valves 5A and 5B, respectively.
B is connected, and the same passages 11A and 11B are smoke nozzle pipes 9.
'It is connected to the. The smoke nozzle 9 at the tip of the smoke nozzle pipe 9' opens into the exhaust pipe 13 of the jet engine 4.

The opening and closing of the valves 5A and 5B are controlled by a controller 10 operated by an operation switch 8.

In this embodiment, the operation switch 8 opens one of the valves 56.5B and closes the other through the controller 10. For example, when the valve 5A is opened and the valve 5B is closed, the fuming oil 2^ in one of the fuming oil tanks A is transferred from the fuming nozzle 9 through the passage 11A, the valve 5A, and the fuming nozzle pipe 9' by the pump 3A. It is injected into the exhaust pipe 13 of the jet engine. The injected fuming oil is vaporized by the exhaust 6 of the jet engine 4 and generates smoke 12 of a color corresponding to the pigment mixed in the fuming oil 2^. After an appropriate period of time has elapsed, when the operation switch 8 is operated again to open and close the valves 5A and 5B via the controller 10, the smoking oil 2B in the smoking oil tank B is discharged from the exhaust pipe 13.
The smoke 12 of different colors is generated.

By repeating the above operations, as shown in FIG. 2, a spotted two-color smoke 12 is generated from the aircraft 14.

Further, according to this embodiment, the color of the smoke 12 from the aircraft 14 can be changed from one color to the other depending on the outside situation that generates the spotted smoke, and smoke of a desired color can be selected and generated. You can also do that.

A second embodiment of the present invention will be described with reference to FIG.

This embodiment differs from the above-mentioned first embodiment in the following points, and the common parts in FIG. 3 are those in FIGS.
The same reference numerals as in the figure are given, and the explanation thereof will be omitted.

In this embodiment, smoke nozzles 9A and 9B that open into the jet engine exhaust pipe 13 are connected to the passages 11A and IIB connected to the smoke oil tanks IA and IB, respectively.

In this embodiment as well, as in the first embodiment, it is possible to generate two-color smoke 12 such as a spotted shape.

A third embodiment of the present invention will be described with reference to FIG.

This embodiment is for a twin-engine aircraft with two jet engines, counter-sink jet engines 4A and 4B, and one smoke nozzle 9^ of the second embodiment is inserted into the exhaust gas of one jet engine 4A. The other smoke nozzle 9B injects the smoke oil into the exhaust gas of the other jet engine 4B.

In this embodiment as well, smoke of two colors can be generated as in the first and second embodiments.

Although the above embodiments all generate smoke of two colors, it goes without saying that the present invention can generate smoke of three or more colors.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to obtain multi-colored smoke such as a spotted pattern from an aircraft, and it is possible to improve the display effect.
