with reference to 2 Claims. (01. 46-76) 2,609,660, and Serial No. 660,118, filed April 6,
1946, for Pulse Jet Unit with Mounting and Cooling Construction, andthe copending application of Leroy E. Black, Charles B. Marks and William L. Tenney, Serial No. 661,280 filed April 11, 1946,
' for Pulse Jet Device,- since matured into Patent Number 2,587,100,
The jet propulsion unit generally designated l0 includes a combustion chamber 1 I- which is connected by a converging section l2 to a jet pipe I3 which terminates in the flared jet and orifice M. The front of the combustion chamber is closed by a combined air intake and valve plate assembly generally designated I5 having a plurality of intake ports I 6 which are connected by intake passages that converge to form the Venturisection H which has a forwardly flared air intake portion 18. The parts l6 are covered by a valve plate 20 of petal configuration, one valve petal being over each of the'valve ports. The valve member 20 is held in place by a curved back stop 2| which is in turn fastened tightly by the cap screw 22 so as thus to hold the valve firmly in place. Extending forwardly through the Venturi section is a fuel pipe '24 which terminates in one or more fuel orifices 25. The fuel pipe is screwed into the conical central part 26 of the valve plate and hence is held in a fixed position centrally of the Venturi section [1. The fuel pipe has a ball shaped protuberance 21 thereon and a side arm 28 which supports the pipe 29 to which a hose is attached for introducing air under pressure into the 'Venturi section I! for starting. An ordinary bicycle pump .or pressure supply tanksufiices for purposes of starting. Once the unit is started the starting air hose connection to pipe 29 may be removed. The jet unit then operates with a self-induced resonant pulsating action, the combustion .chamber and the exhaust tube which opens directly and freely thereinto forming parts of a. system resonant in gases in which a rapidly occurring reversal of flowof gases takes place,
' causing periodic drawing in and combustion of fresh charges of fuel and air through the Venturi inlet l1 and valve 20. This produces discharge of a high velocity, rapidly pulsating and reversing fiow of hot gas in the form of a jet fromthe open end 14 of the discharge tube.
The jet propulsion unit is enclosed within a fuselage section generally designated 30 which has amaximum girth at the mid-section 3i and is reduced very slightly in girth at its forward end 32 and reduced gradually in the rearward direction so as to provide a smooth uninterrupted exterior section terminating at 34. The'jet unit It is mounted by radial fins 35 which are attached to the exterior of the combustion section II of the jet unit and suitably fastened to the interior of the forward portion 32 of the fuselage section. The fins 35 are spaced radially so as to provide an uninterrupted passage therebetween for the flow of cooling air in the direction of arrows 36, as hereinafter more fully described.
At the rear portion 34 of the fuselage section there is provided a split interior ring 3' l which likewise has on it inwardly extending fins 38 which form a support so as'centrally to locate 'the-rear'end of the jet pipe in the fuselage. The rear end is preferably not fastened to these fins, since the jet pipe expands'jduring operation "and would tend to loosen the mounting 31 3' 8 in the event the fastening was "made tightly. In this manner the jetpropulsion unit is spaced'centrally within the fuselage so that air may flow, as explained, in the direction of arrows 36 and thence continuing in the direction of arrows 39 and40'where it is discharged; If desired, the split ring '31 and fins 38 may be clamped onto the tail pipe l3'and not-'fastenedto thefuselage '30. Hence, as expansion takes place upon heating, the fins 38 and ring 3'l slide within the fuselage. It will be noted thatthe rear end of the fuselage 34' extends slightly rearwardly beyond the outwardly flared-end I'4-of the jet propulsion tube. The jet blast from the flared end [4 thus produces an aspirator effect which draws the cooling air through the space between the interiorof the fuselage and the exterior of thejet :unit. Added thrust is also obtained by this expedient.
The forward end of the model unit is composed of a nose section generally designated 4| which'is smoothly tapered from a minimum diameterat theforwardly curved end'42 to a diameter such that it nests neatly over the front section 32 of the fuselage member 30,-as indicatedv at 44. The two parts thus fit together as a lid on .a can. The nose section is provided with an aperture at 45 through'which connection may be made to the starting air inlet pipe '29 during starting and through which the cooling and combustion air enters the nose section. The nose section also contains a fuel tank at 45 which is suitably fastened in place by riveting "or soldering. The fuel tank has a filling cap 4! which is accessible through opening 45 so 'thfit'ithE tank can be filled when themodel is held vertically. The tank is also provided with an .air inlet orifice 48. The fuel pipe 24 of the jet unit extends forwardly and then dips downwardlyinto the fuel tank asat 49.
The exterior appendages of the unit may be furnished .with the unit or fabricated by the model builder. Inany event they are attached to the exterior of the fuselage and nose section by any suitable fastening. Thus, they may be attached to the fuselage by suitable brackets or bolted or riveted directly to the fuselage, as illustrated with reference to the tail appendages, or may be attached by'a clamping band 50, illustrated with reference" to the wing assembly shown, which is drawn tightly around the rear portion 44 of the nose section by means of clamping screws The wing 52 is fastened to the upper portion 54 of the clamping band on the embossed fiat spot 68, Figure 3, and when the band is then drawn tightly around the rear part 44 of the .nose section, the wing isthus firmly fastened intoplace. The clamping band 50 also serves to support a bent wire frame ground wheel assembly generally designated 55 which has a bent portion 56 that slips between, the clamping band 50 and the exterior surface of the nose section at 44. When the clamping band is thus drawn tightly about the unit the portion 56 of the wheel asa washer or cotter pin to prevent them from falling off. Where fastening other than the clamping band 50*is'used, the ground wheelsupport 55'isattached by suitable brackets or by rivets'or bolts. If desired, .the landing gear may be eliminated entirely, launching'being accomplished by using a take-oif dolly which .drops free after launching, and landing accomplished by 'a skidon the bottom of the fuselage.
' The fuselage section is provided with .a port 59 through which access may be had to the spark plug 60 which is used only during starting of the unit. Once the unit 10 is started, no external ignition is required.
The tail appendages, namely the rudder 6'! and elevator section 62, are fastened by suitable screws or bolts 66 or by a clamping bar about at the rear support 51-135 and the tail skid .64 islikewise fastened to the -ring13l by a screw or bolt 65.
The model airplane'kit. as "manufactured, includes the partsiin knocked down conditionand the model airplane builder, therefore,x,need only assemble them and apply :a suitable finish to any of the parts desiredin order to have .a complete and operative. jetpropelled .-model airplane. Since the assembling can be accomplished with simple tools, no great skill is required to com plete' the model. The clamping of the bar '50 around the exterior portion 44iof the nose section 4i serves very :slightly to reduce its diameter (at 44) and to hold it firmly upon the fuselage section 30 which, as previously explained, also serves'to support the wing 522 and the ground wheel assembly 55. The clamping band also causes pressure to be exerted upon the interior supporting'fins .35 of the jet unit ID, with the result that it too is firmly anchored once the bolts "5| are drawn tight. .Ihus, the entire assembly of the parts is made by the two screws 5|. The entire assembly of the tail'appendages 6! and 62 and skid 64 is made by a few metal screws or bolts '55 and 66. Where desired, the manufacturer may sell the unit'less the wing section 52, the rudder Bi and elevator 62, there parts being left to the ingenuity of the model builder to fabricate and assemble onto the unit. These parts may be made of wood, if desired, since the illustrated structure keeps the fuselage temperature desirably low.
The details of fastening-of the wing section to the clamping band '55 are best illustrated in Figured WllEIEll'lltWlll be noted that the clamping band is provided with a bumped up nearly horizontal fiat section 58, that serves me. firm support for the under side of the wing 52which is held in place on the band 50 by screws or rivets 69. Once the wing is fastened to the clamp band 50, the remaining assembly operations are made as previously described.
In the model illustrated in Figures 1-3 the nose section 4| is of metal which is drawn or spun to the shape shown. In the model illustratedin Figures 4, 5 and 6 and also in Figure '7 the nose section is fabricated from a light weight wood such as balsa or white pine. Thus, referring to Figures 4, 5 and 6 the jet unit In is as previously described and is supported from the fuselage 30 by means of interior radial spacing and supporting brackets 35. The ground wheel supporting frame 55 and the wing section 52, as well as the rudder Bl, elevator 82 and ground skid 64 are likewise supported as described with reference to Figures l- 3. However, the forward portion of the model is composed of a wood nose generally designated 10 which is carved out so as to provide a space to contain the gas tank 46. The upper portion Of the nose section is provided with a cut out opening at the bracket 7| through which combustion and cooling air enter through the nose of the unit. The rear edge 12 of the nose section is nested into the front part of the fuselage section 30 and is held in place by a plurality of wood screws or small bolts 73 and the forward edge of the metal fuselage at 74 may then be headed down slightly, if desired, so as to present a neat appearance at the junction of the metal and wood portions of the model. If desired, the nose piece may be reduced in diameter by the thickness of the fuselage metal so as to present a smooth exterior surface.
In Figure 7 the method of supportingthe jet propulsion unit is slightly modified in that the wooden nose section 10 is provided with a support ring 15 which has a rim 16 and a central apertured hub 11 that are connected by a plurality of radial spokes 18 so as to provide a plurality of openings through which cooling air may enter through the nose and thence flow over the jet unit. In this type of mounting the front end 18 of the jet unit air intake is provided with a forward tubular extension 19 which has an exterior diameter so as to fit neatly into the opening in the hub 11 of the support ring 15 where it is held by a ring nut 80 which is threaded onto the front part of the tubular section 79. The fastening screws or bolts 8| extend from the exterior surface of the fuselage 30, thence through the shell of the wooden nose piece 19 and thence through the rim part 18 of the supporting ring thus holding all of the'parts in firmly assembled relation. It is obvious that by firmly cementing the ring 16 into the wooden nose piece 10 beforehand, a firm juncture may be made between them and that the model builder can thereafter easily drill through the fuselage and assemble the nose and ring section for placing the fastening bolts 8| or simply place the fastenings 8| through apertures already provided by the manufacturer for this purpose. In this instance also the forward end 82 of the fuselage 30 may be beaded down after the assembly is made for purposes of neat appearance.
As many apparently widely different embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that I do not limit myself to the specific embodiments herein except as defined by the appended claims.
What I claim. is:
1. A pulse jet engine powered aircraft charac terized by having a fuselage of generally tubular character with a rounded forward end and an open rear end, a wing on said fuselage, a pulse jet engine including a combustion chamber and an exhaust tube of generally tubular character opening directly into said combustion chamber and forming therewith integral parts of a system resonant in gases, said engine extending slightly forward of said Wing and having a short air intalre at its forward end with the discharge end of said exhaust tube extending adjacent but terminating just short of the end of said fuselage and being of smaller diameter than said fuselage, means for supporting said engine within said fuselage in spaced relation therewith around the entire circumference forming a passage for the rearward flow over the entire extent thereof of air for cooling and thrust augmentation, said supporting means including a forward support fixedly securing the combustion chamber within the fuselage and a rearward support for slidably supporting said exhaust tube within said fuselage to allow relative expansion thereof while maintaining a through passage for said rearward flow of air therethrough.
