B Claims.
This invention 'relates to an improved rocket missile of the of 'rotating type.
a rocket missiie or projectile of 'the 'spinning or rotating type generally consists of two secl-I t'ions, that is, 'a warhead section and a rocket motor section. "The impulse from the rocket motor section v`'propels 'the 'its 'pipellant is completely consumed, after which the projectile warhead section continues along its trajectory by momentum. Due to the 'fact 'that the rocket ni'o'txr section may interfere with properoperation nof the projectile warhead section, because o'f after-burning'which leaves -ionicing gases and flame, and because Vof mechanical disturbances to the ying system which prevent the fuze mechanism from functioning prope'rly, it has been found desirable for best operat-4 ing conditions to release "the 'rocket motor section from the projectile warhead section after the propellant has been fully bln-ned or consuined.
It is one of the objects of the presentinvehtion to 'provide improved means for effecting the separation of the rocket motor section vfrom the missilewarhead section after the propellant the rocket motor section has been consumed.
Still another object of this invention is to provide means for releasing th'e motor section of a rocket projectile which will be efcieht and 'reliable in operation.
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 conjunction with the accompanying drawing, and which:
1 is an laxial section 'f a rocket niss'ile oi' the spinning or rotating type, showing the .releasingmeans according to the invention; and Fig. 2 is a cross section on the' line 2-2 of Fig. 1.
In accordance with the invention, Y'means are .provided for eiectng the separation of the rocket motor section from the projectileproper after the propellant has been consumed, for that type of aerial missile designed to spin or rotate in flight. This is accomplished by means of a releasabl'e couplingwhich is provided between the r'notor section 'and the projectile warhead section of the aerial missile. This coupling includes cooperating shoulders on the motor and projectile sections, balls arranged to engage the cooper` ating shoulders, a tapered cup surrounding the balls and holding thm in engagement, and a plunger on the which is acted on by the pressure "from the rocket propeiiant to hold Vthe cup in engagement with the heus.
A spring is also provided foi moving the cup away from the hails upon reduction of pressure on :the plunger. lDetents 'are provided to 'prevent action of the spring 'prior to the iiiing f the rocket missile. These detente` are (freed by the action o'i the gas pressure on the puihgei, and they are disengaged by the action of the een-5 t-ifgal orc'e set up by the rotation or spin t the missile during its, 'course of night. After the rocket propellant has been consumed, the gas pressure en -the lplunger decreases uhtii lit isovercome by the pressure due 'to the When this occurs, the cu'p is forced clear of the balls, thereby permitting them to be thrown clear of the cooperating shoulders by centrifugal force to unlock the coupling means and'ths sep; arate the rocket motor section rom the *lr'iissile warhead section.
Referring now u) the figures of the drawing. there is 'shown an aerial missile IU of the rocket spinning or rotating type which consists generally 'of a rocket motor section i? and a warf head section I H. The rear end |6 of 'warhead section il! is of reduced-diameter and is threaded es indicated at is. A fitting 2o of houow shape screwed onto the 'reduced end i'B of warhead section I t. Fitting '2b metes with e, cupe-'shaped n ttiugz which is screwed, by threads 21:,ihto the` internally threaded forward end 2e o'f the cket i'n'otoi'j section '12.
A disk is is screwed ihto the threededpoi-tion et o r a eupesheped cavity a2 in the motor h'tt'ihg 2'2 for e sufueieht distance 'to eiser the epd oi the warhead fitting- 20. A t'ube '3B having a radial anle 3B 'is secured in 'a central bore '38 in the warhead nttihg in and projects through an asiel opening #s ih the disk 2s.
steei'baus' t2 aye forced radially inward ege-inst the tuhe 3H and between its shoulder` tt and the disk 28 by thecamming action of the inclined inner wall 35 'of 'a 'cup i8 carried on a threaded plug' 50 extending through a tapered axial b'r 52 the motor fitting 22. Detehts 54 are ih'- se'rted in apertures or ker'fs' in theplug 50 to prevent backward ni'ovement of the plug Si) and c ip Vdue to the pressure 'of a spring 52! 'enclsed in the tube '34 and bearing against the refereed ehu et o'f the plug. Se and against a disk 62 closing the forward end GB of tube 34.
Beus ai look the two sections 12 and il toother aiiaihs't the separating eiieet of the spring 5t by reason of' their 'being placed between the disk it and the fediai danse et rof' the tute 3a.
At the same time, the detents 54 are prevented froml dropping out of the apertures in the plug 50 because they are forced against the forward wall of the motor fitting 22 by spring 58.
Having described the invention, the operation thereof will now be explained briefly. After the aerial missile IIJ has been launched and is in free iiight, the gas pressure in the rocket motor section I2 acts against the rear end 68 of the plug 50 and forces it slightly forward, causing it to seat in the tapered wall 52 in the motor tting 22, and simultaneously releases the detents 54, so that they can be dislodged by centrifugal force set up by the spinning or rotating of the aerial missile I0.
At the end of the burning period of the propellant in the rocket section I2, the gas pressure decreases to a value at which the spring 58 can force the plug 50 and cup 48 rearwardly to release the balls 42, which are then thrown radially outward due to centrifugal force caused by the spinning projectile I0, and thus unlock the disk 28 and the tube 34. The rearward motion of the plug 50 and the cup 48 pushes the plug -50 from the tapered wall 52 of the motor tting 22, admitting gas pressure to the cavity 32 between fitting 22 and the projectile fitting 20 to force the projectile section I4 and the rocket motor section I2 apart. The projectile or warhead section I4 will then continue along its trajectory or course of flight and motor section I2 will drop earthwardly.
Obviously 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 specically described.
