GYROSCOPIC ROCKET.

Specification of LetteYs Patent. Patented NOV. 22, 1910.

Application filed June 8, 1910. Serial No. 565,674.

To all whom may concern:

Be itknown thatl, NICOLAS Gnnuassr- Morn, a subject of the .Czar of Russia, re-

of St. Petersburg and Empire of Russia, have invented new and useful Improvements in Gyroscopic Rockets, of which *the following is a specification. p The object of the present invention is to use the recoil and energy of the gases produced the combustion of explosives to project b objects into the air, an impulse in the .desired direction being given to them during-a certain' interval of time. The object projected is, at the same time, given stabilityin the air by means of masses provided within the said object which revolve at a high speed about an axis parallel to the direction of motion.

The accompanying drawing shows by Way of example a longitudinal section on the. axis of a gyroscopic rocket constructed ac cording to the present invention. The rocket consists essentially of two cylindrical casings a and b of sheet-steel which are placed end to end. The casing a contains cylinders c, d, c of compressed powder or other slow-burning explosive. In order 40 ing a by means of clamps, bolts, screws or to expose the surface necessaryiforhthe formation of a large quantity of gas at the moment of explosion, which latter is started by the firing f in any suitable manner, the cylinders 0, d, e are hollowed out for the greater part of their height as indicated in the drawing the number of these cylinders, which burn one after the other, depends on the length of time the explosive is required to urn.

The casing b which is fastened to the easother suitable means, is separated from it by a cover 6, and contains a shaft 9 one end of which is supported, inorder to reduce frictional resistance, by a ball bearing, h, mounted in a cage or socket formed 1n the cover I). The other end of the shaft is supported by a bearing 71, which is held central in the end of the casing 12 by means of a number of radial arms connecting it to the circumference of the said casing.

Two wheels j and 7c are keyed upon the shaft 9. -The wheel j is constructed in, the

'form of a Pelton wheel or other turbine wheel and constitutes the driving wheel of the gyroscopic system, The wheel lc is the propulsion whee The driving wheel 7' is an essential and necessary part of the system while the wheel is could be replaced if desired by the blades of a screw propeller.

The apparatus acts as follows: The gas liberated by the combustion of the explosive (cylinders c d c) rushes out at a high velocity through the holes Z provided in the bottom of the cover I) and produces the recoil pressure of the rocket, being then di-.

rected by the guide-pieces m onto the vanes of the driving wheel 7' to which it imparts a high rotative speed. This rotation is transmitted by the shaft 9 to the propulsion wheel is. The gases leave the wheel j with a lower velocity than that with which they entered it, and .are then directed by the guide surfaces n,to openings o in the wheel /c which are formed close to the axis of the latter. The gases pass through passages 32 in this wheel, and since these passages open nearer the circumference than the openings 0, the gases leave this wheel is with a higher velocity than they had when entering the openings o, but with a lower velocity than their initial velocity when entering the wheel It is evident that, by thus increas-- ing the velocity of the gases, the wheel it: receives an impulse from the gases in the direction of mot-ion of the rocket and communicates it to the latter thereby increasing thevaction of the recoil. the rapid rotation of wheels 7' and la gives the rocket the desired stability in the air. The objects-to be carried by the rocket are placed-at its head.

at a point on the other side of the wheel On the other hand It will be understood that the invention is not strictly limited to the exact arrangement described above and illustrated in the drawing, for it. is evident that certain modifications could be made in the detailed construction of the various constituent parts of the system, such as might be shown in practice to be advantageous or necessary, without departing fromlthe spirit of the invention.

I claim: o 1. In a gyroscopic rocket, the combination of an exploslve charge; a gyroscopic device comprising a driving and a propellin Wheel, carried by to give stability to said rocket during flight;

and means for leading the gases evolved. from sald charge to said gyroscopic device,

for. the purpose of rotating stantlally as' described.

2. In a gyroscopic rocket the combination the same, subsaid rocket and adapted scribed.

of an explosive charge; a driving wheel adapted to receive thetgases evolved from said charge; a propelling wheel driven from said driving wheel and provided with means for increasing the velocity of the ases received from said driving wheel sai wfheels being of suflicient weight to constitute a gyroscopic device adagfed to give stability ght; and means for to said rocket during g said charge, substantially as deignitin 3. In a gyroscopic rocket, the combination I of an exploslve charge; a casin containing g said charge; a driving wheel a apted to receive the gases evolved from said charge; a propelling wheel driven from said drivlng whee land provided with means for increasing the veloeity of the gases received from said driving wheel, said-wheels being of suflicient weight to. constitute a gyroscopic device adapted 'to give stability to said rocket during flight; a second casing having perforations for the esca e of-gases, containmounted in said ing said wheels; a sha second casing carrying said wheels; and

means for igniting said charge, substantially PAMsKY;
