ABSTRACT OF THE DISCLOSURE Apparatus for firing in sequence a plurality of flares or other pyrotechnic devices. A plurality of flares are arranged circumferentially within a tubular housing, each flare being contained within a barrel which also includes a spring-loaded firing pin. All the pins are restrained from movement toward their associated flares by a rotatable plate having a single slot formed therein. When the plate is rotated, this slot is brought into successive alignment with different ones of the firing pins to permit the particular pin then in alignment with the slot to be propelled by its spring toward its associated flare to fire the latter. Sequential firing of all the flares results from continued rotation of the plate.
The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
The present invention relates generally to flare launching means and more particularly to a method and means for containing a plurality of flares or other pyrotechnic devices each of which may be fired singly upon command from a remote station.
Recovery of personnel, missiles, rockets and other objects from either the sea or lakes or from remote land areas is often a costly and lengthy procedure due to lack of an adequate marking or location designating device such as a flare or-radiosignal. Recovery at sea is even more diflicult due to the vast areas to be viewed or scanned and to the relatively minute size of objects which may float and therefore be susceptible of recovery.
Conventional flare devices are generally single shot in nature making it very difiicult for targets to be located within the time the flare will remain burning. Also, the available flare devices are usually released on the occurrence of an impact or a preselected temperature or other condition rendering it necessary that the recovery personnel be within viewing distance of the object at the time the flare is fired. There is thus a need for a flare releasing method and mechanism which will store flares at the cality where an emergency may develop or store flares in a vehicle which is desired to be recovered and whose exact trajectory and landing place may not be readily or closely enough ascertained so as to permit rapid recovery by planned recovery procedures. Another situation where conventional flare devices are unsatisfactory is in the case of personnel downed at sea or on land remote from conventional rescue teams. In such cases where these personnel are incapacitated and therefore unable to launch flares a device which will fire the flares upon command emanating from a search vehicle is quite essential in order to quickly ascertain the location of the downed personnel.
The present invention overcomes the disadvantages and shortcomings of prior flare launching methods and devices and provides a magazine containing several flares which may be fired at any desired time to assist in location of the site. The flares may be fired by radio or electrical signal which actuates a solenoid to successively fire flares from a flare magazine.
Accordingly, it is an object of the present invention to provide a flare storage and firing mechanism which is operable by remote command.
It is another object of the invention to provide a flare magazine or housing containing a plurality of flares which may be individually launched as desired over a period of time.
A further object is to provide a flare launch method and mechanism having a quantity of flares arranged for sequential firing on remote command, which may be mounted in a missile or rocket and will satisfactorily withstand the shock of rocket launch and landing.
A still further object is to provide a flare storage and remote firing mechanism which will withstand drop by parachute and thereafter serve to identify and illuminate an area to which rescue teams may be directed.
It is a further object of the present invention to provide a rugged flare storage and firing device which is simple in operation and yet provides for selective discharge of flares by either local or remote control.
Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings in which like numerals designate like parts throughout and wherein:
FIG. 1 is a schematic view of a device embodying the present invention employed to assist in the recovery at sea of a missile nose cone;
FIG. 2 is a vertical sectional view, partly in elevation, of the embodiment illustrated in FIG. 1 (for simplicity background details are omitted);
FIG. 3 is a top plan view of the embodiment shown in FIG. 2; and
'FIG. 4 is a side elevation somewhat enlarged and partially broken away of a safety locking device.
Referring now to FIG. 1, the present invention is shown attached to one end of a nose cone 10 of a missile floating nose down in a body of water with the flare storage and firing device 11 attached to the exposed connecting interface 12 of the nose cone and oriented to direct the flares upwardly. As shown in FIGS. 2 and 3 the device includes spaced upper and lower plates 14 and 15 which are interconnected by a tubular collar 13 and support a plurality of peripherally located barrels 16 each of which carries a flare or other pyrotechnic device 17. The flares are fired through operation of a rotary solenoid 18 which may be battery operated and may be remotely controlled through a radio command link including a receiver 19. A circumferential shield 20 provides protection for the flares. Although this embodiment of the device is shown attached to a buoyant nose cone it may readily be appreciated that the carrying vehicle may be a target plane, a test device or other suitable object and the flight may have terminated on land rather than on water.
The upper and lower plates 14 and 15 are held in spaced relationship by collar 13 while a second collar 24 suspends solenoid 18 below plate 15. Barrels 16 are received in aligned peripheral openings in plates 14 and 15 and are secured therein by set screws 25 in plate 15. Each barrel is internally threaded at the lower end to receive a plug 27 and at the upper end to receive a flare or other pyrotechnic device 17. Shaft 30 extends upwardly from the rotary solenoid 18 and is journaled in roller bearings 31 and 32 provided in plate 15 and 14. The upper end of shaft 30 immediately above plate 14 carries an extension forming a rotor assembly generally indicated at 35 which includes an enlarged hollow tube 36 having a radially extending firing pin restraining plate 37 around its lower portion. This rotor assembly is secured to the upper end of shaft 30 by a cross pin 40.
As best shown in FIGS. 1 and 2, upper support plate 14 carries protective shield 20 which may be affixed to plate 14 by such means as bolts and nuts 42 which hold lugs 43 of the shield to plate 14. Plate 14 and rotatable plate 37 are spaced from one another along the vertical axis 44 of the device. with the rim of plate 37 notched at 46. A stop block 47 is shown aflixed to upper plate 14 by recessed bolts 48, and a passage 49 therethrough accommodates a ball lock safety pin 50 shown in detail in FIG. 4. Housing 51 is attached to plate 14 and received in collar 13 to accommodate the lower end of pin 50. Each barrel 16 is provided with an elongated slot 52 through which projects a threaded screw 53 of the respective firing pin release assembly 54. In the ready position for launching flares, firing pin assemblies 54 are all retracted but are urged against the under surface of plate 37 by the upward force of firing pin springs 57 which force is exerted against the base of firing pins 58.
Ball lock safety pin 50 may have a ring 60 connected thereto to which a lanyard may be attached for effecting removal of the ball lock pin when flare device is readied for service. Ball lock pin 50 prevents rotation of plate 37 until such time as it is desired to prepare the device for operation.
Firing pin release assembly 54 is shown in detail in FIG. 2 and includes a roller bearing 62 mounted on screw 53 so that the roller bears against and rolls along the undersurface of restraining plate 37. When slot 46 registers with each roller assembly it permits movement upward of release assembly 54 and the associated firing pin to fire the flare aflixed to that barrel.
In FIG. 3, the release assemblies 54 are shown positioned under plate 37 at points around the periphery thereof such that stepwise rotation brings slot 46 into successive registry with successive assemblies thereby permitting each assembly to move upwardly under the urging of its spring 57. Tubular extension 36 may be manually rotated by gripping the upturned protruding ends of a second cross pin 64 and may be provided with a short collar as shown at 65 to receive a cover-securing ball lock pin 67 which pin may also be used to secure cover 68 against the side of shield 20 when the device is readied for use.
In operation, flare launcher 10 is attached to an ob- 'ject which is to be recovered, or is prepared for use in marking a site or area, and cover 68 is secured to shield 20 preferably as shown in FIG. 2. Each of barrels 16 is armed for operation by depressing its respective firing pin 58 and thereafter rotating restraining plate 37. Springs 57 are thereby compressed until all release assemblies 54 bear against the under surface of plate 37. The safety or arming pin 50 is now inserted to provide a positive lock against rotation of plate 37. In this condition all barrels are ready and flares 17 now may be aflixed to the top of each barrel.
In the embodiment shown eleven barrels are spaced 30 around the periphery of the device, the remaining 30-degrees sector being reserved for the safety or arming pin assembly shown in FIG. 4. With the flares installed and the cover mounted at the side of the shield the device is ready for operation upon removal of the arming pin 50. Solenoid 18 may be activated by a locally generated electric current or remotely by radio control acting through suitable batteries. Such activation causes rotary solenoid 18 to rotate one step or 30 thereby freeing the firing pin restraining assembly 54 for the first barrel. Successive activations release succeeding barrels in sequence.
The device is shown adapted to be employed in missile nose cone recovery operations, however, in launching the device from an aircraft a lanyard attached to ring 60 could be so secured that upon the device falling away from the plane arming pin 50 would be withdrawn freeing plate 37 for rotation. Upon recovery of the device the cover 68 should be secured over the open top of shield 20.
The device may be mounted on any type of vehicle and used to fire flares, smoke generation pyrotechnics, or any other type of signal means which can be initiated by percussion. Since the device is primarily powered by springs, it requires only a relatively small amount of electrical power. Although the embodiment described was devised to fire flares to assist in recovering capsules from the ocean, it will be appreciated that its ruggedness and safety features make it applicable for launching from other objects as when parachuted to remote areas where illumination by flare is desired. The quick release ball lock pin attached to the lanyard provides for automatic arming of the device upon being dropped or otherwise launched from a plane or other vehicle. The safety recovery feature, cover 68, provides protection for personnel who .are retrieving the device or persons who handle the vehicle containing the device upon recovery against an unused flare being fired by accident.
The present invention will fire a rocket flare several hundred feet into the air, being visible as far away as 30 or more miles. When operated by radio command, the flares may be fired at any interval of time by recovery personnel aboard searching aircraft. The use of eleven barrels and flares in the present embodiment is not intended to be limitative, it being appreciated that more or fewer flares may be contained and also that the flares may be contained in more than one circular ring about the rotor.
There are distinct advantages of the present device over such conventional area identification means such as dye markers, smoke generators actuated upon contact with sea water, or electrically ignited squibs which require much more power and therefore are limited in the number of flares that may be carried as well as in the efficiency of firing these flares. The flares used in the present device may carry a greater charge than those usable in conventional flare mechanisms resulting in a much greater altitude and range of visibility.
The device may be constructed of several types of material such as plastics, ceramics or metals or alloys as desired according to environmental requirements. A spring motor may be used to replace the solenoid if desired. It will be recognized that many modifications and variations of the present invention are possible in the light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
