v like.
When the above propellants in combination are subjected to an intense flame they are heated sufficiently to ignite and oxidize the fuel, resulting in the desired expansion and effecting a propulsive jet from the discharge nozzle of the unit,
The present invention is particularly directed to an improved starter for liquid jet propulsion units and has as one object the provision of compact means supplying a pilot flame to positively ignite the propellants, which means is loperated independently of the main fuel nozzle.
An additional object of the present invention isvto provide in a jet propulsion starter assembly, combined fluid flow control means and spark producing means which may be operated to furnish the initial heat of combustion Ifor propulsion starting purposes.
A further object is to provide an independent liquid propellant igniting and burning device continued operation of which serves to protect portions of the starter mechanism from damage by the heat of normal combustion.
It is a further object to combine in a pilot combustion supply device means for protecting said device against the products of combustion and means for automatically terminating a portion of the pilot operation upon proper ignition K of the main -fuel charge.
Other objects and advantages will be hereinafter more fully described and for a complete understanding of the nature, scope and characteristics of this invention reference may now be had to the following description and accompanying drawings, in which latter:
Fig. 1 illustrates a schematic fuel system partially in vertical cross-section showing one embodiment of the present invention.
Fig. 2 is a schematic fuel system showing another embodiment of the present invention.
`The system employed may comprise a high pressure tank I0 containing a suitable gas under very high pressure the discharge of which through line Il may be controlled by means of reducing valve I2. The gas under high pressure then passes to a T connection I3 where it 'is distributed through lines I4 and I5, as shown. Line I4 applies pressure to a main propellant fuel tank I6 while through line I5 pressure is applied to a liquid propellant or oxidizer tank l1. Discharge of propellant liquid from these tanks through lines i8 and i9 may be controlled simultaneously by electrically operated valves 20 and 2l to permit the contents to be directed into the usual liquid combining nozzle 22. A suitable electrical switch 21a may be provided so as to operate the valves 20 and 2| together.
'I'he nozzle 22 discharges into an enlarged spherical combustion chamber 23, as shown, and the propellant liquids when they are ignited forcefully expand and emerge through jet propulsion nozzle 24 to provide the desired propulsion effect.
The starter mechanism of the present invention comprises the valve seat housing 3l which is provided with a plurality of seat encircling apertures 32 leading from the annular recess 30 and through which liquid propellant from tank I6 is projected into the combustion chamber 23. As the fuel so supplied must be mixed with air or another oxidizer before it can be ignited for starting purposes there is provided a separate motor driven blower 33 which forces air through conduit 34 into the space 35 within the valve seat housing and from the lower portion of which it emerges to mix with the liquid fuel emerging from the inwardly directed apertures 32 rforming therewith a suitable combustible mixture. An inlet valve 3G having a head 31 may be employed to control the air flow in a manner hereinafter to be described. l
In order to ignite the fuel and air mixture thus provided, a high tension electric spark may be caused to jump from the head 31 of the valve to a seat 38 thereby igniting the fuel and air mixture. This high tension current may be supplied in any desired manner as well known in the art through a suitable cable 39 which is connected to the upper end of the stem of valve 31. This stem is mounted for vertical reciprocation in a block 40 of suitable insulating material and is surroundedby a compression 4spring ll which bears against washer 42 secured on the stem and normallyfurges the valve into the open position as shown.
In operation, valve I2 is flrst opened to permit pressure to be applied to the liquid propellant in tanks I6 and |1. No propellant can pass through valves 28 and 2| since they are closed, however, liquid fuel may pass through line 2B to valve 21. Valve 21 may then be opened by the operation of switch 28 to permit fuel under pressure to flow through line 28 and emerge from the inwardly directed apertures 32 which surround the valve seat.
Simultaneously with the above described procedure the electrically. operated blower 33 may be started as by means of the electrical circuit 28a whereby it will deliver air through conduit 3l so that it emerges 'through the angular space surrounding the valve.
Concurrently with the above a high voltage current may beA supplied through conductor 39 and be caused to jump across the space from the head 31 of the valve to seat 38 effecting instantaneous ignition of the combined fuel and air mixture. I
It will be apparent that the combustion thus occurring within the combustion chamber slightly increases the pressure therein, however, spring 4| is of suflicient strength to prevent the valve from being closed by the amount of pressure so created.
With the pilot flames produced and in operation as above described valves 20 and 2| may thereupon be opened by operation of electrical control switch 2la so that liquid fuel and oxidizing mixture in the desired proportions may be forced from supply chambers I8 and I1 into the discharge nozzle 22 from which they emerge into the combustion chamber 23. The liquid propellants so supplied are immediately ignited by the intense heat already existing within the combustion chamber 23 by reason of the pilot iiame. The greatly increased temperature and resulting rise in pressure is now sufficient to overcome spring 4| and forces the valve head 31 upon the seat 38.
Because of the intense temperature rise which exists within the combustion chamber 23 liquid fuel is supplied to the valve seat during the entire jet operation and emerges from the apertures 32 being directed by these apertures in a spray over the valve head 31. The eilect of this operation is to blanket or protect the valve head 31 from the heat, cooling the head and preventing warping or other deleterious effects as a result of this heat. ,l
When valves 28 and 2| are closed the propellant chamber pressure drops and permits the spring loaded valve to lift from its seat. The igniter may then be operated as before and continues to operate as desired.
In the'embodiment illustrated in Fig. 2 a modication of the present invention is shown Wherein the igniter heretofore described may be adapted for use with a monopropellant such for example as nitromethane (CHaNOz). In this embodiment the nitromethane takes the place of both the fuel and the oxidizer and may be stored in a single fuel tank or there may be provideda monopropellant tank 50 and an ignitor fuel tank which later may contain 4 either the monopropellant or a separate igniter fluid.
When separate tanks are employed the monopropellant may be led from tank 50 through line 52 controlled by valve 53 which may be remotely operated by means of switch 54. Monopropellant is thus conducted to the main fuel nozzle 22 in the manner hereinbefore described with regard to the first embodiment.
In Fig. 2 the igniter fuel tank 5| is shown connected by outlet line 55 to the igniter nozzle and the flow may be controlled by the valve 21 as was hereinbefore described with respect to the first embodiment.
vIn operation the device of the second embodiment, whether employing monopropellant or some other fluid for ignition purposes, conducts fuel from tank 5| to the ignition chamber where it is mixed with air entering through conduit 3l and by the means hereinbefore described is ignited tc provide a pilot iiame in the combustion chamber. Monopropellant subsequently injected from the main discharge nozzle may be ignited by this pilot flame. If monopropellant alone is to be used for both the ignition and mam discharge jets then obviously tanks 50 and 5| may be combined.
From the foregoing description it will be apparent to those skilled in the art that various modications thereof may be made without departing from the spirit and scope of this invention and it is desired, therefore, that the same be limited only by the scope of the appended claims.
The invention described herein may be manufacturedand used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
