A jettisonable nosecone (10) for a missile is specified, which nosecone (10) is longitudinally split into at least two parts (15, 16) and is held together by detachable connecting structures, in which case the connecting structures are designed to actively move the at least two parts (15, 16) away f
A jettisonable nosecone (10) for a missile is specified, which nosecone (10) is longitudinally split into at least two parts (15, 16) and is held together by detachable connecting structures, in which case the connecting structures are designed to actively move the at least two parts (15, 16) away from one another when released. A missile having a correspondingly designed nosecone (10) is also provided. A nosecone (10) of this type allows simple jettisoning during every flight phase of the missile, and is also suitable for retrofitting to an already existing missile.

What is claimed is: 1. A jettisonable nosecone for a missile, said nosecone being longitudinally split into at least two separate parts (15, 16), and detachable connecting means for holding together said at least two separate parts (15, 16), the connecting means being releasable for actively moving
What is claimed is: 1. A jettisonable nosecone for a missile, said nosecone being longitudinally split into at least two separate parts (15, 16), and detachable connecting means for holding together said at least two separate parts (15, 16), the connecting means being releasable for actively moving the at least two separate parts (15, 16) away from one another, said connecting means comprising a connecting pin (60) which is pyrotechnically activatable, said connecting pin (60) including a hole (65), a propellent charge (66), being arranged in said hole to enable gases to be released on initiation of the propellent charge (66) for driving said at least two parts (15, 16) away from one another, said connecting pin (60) having a weak point (63) in the central portion thereof facilitating rupture of said connecting pin responsive to initiation of said propellent charge (66), said at least two separate parts (15, 16) being held together by the connecting pin (60) threadinaly engaging hollow cylinders (54, 55) which are axially slideably inserted into one another and form an internal cavity (57) extending about a central portion of said connecting pin (60), opposite outer ends of said hollow cylinders (54, 56) contacting inner surface portions of, respectively, said at least two separate parts (15, 16) the hole (65) in the connecting pin (60) including at least one opening (64) communicating with the internal cavity (57), via which the gases which are released on initiation of the propellent charge (66) and which drive the hollow cylinders (54, 55) axially away from one another upon rupture of said connecting pin, flow into and expand within the internal cavity (57) for causing said hollow cylinders to force said at least two separate parts (15, 16) apart from each other. 2. A jettisonable nosecone according to claim 1, wherein the nosecone is selectively conical, in the form of an ogive, or paraboloid in longitudinal cross-section. 3. A jettisonable nosecone according to claim 1, wherein the nosecone has a trailing end including a peripheral convex bead (40) extending into a concave groove formed in said missile for connection therewith. 4. A missile having a jettisonable nosecone according to claim 3, wherein the convex bead on the nosecone engages in a raised collar (49) on the missile having the concave groove therein which runs in the circumferential direction thereof. 5. A missile according to claim 4, wherein the raised collar (49) is intermittently interrupted in the circumferential direction thereof. 6. A jettisonable nosecone according to claim 1, wherein at least one angled groove (42) for guidance of at least one pin (52) which is arranged on the missile is formed on the internal circumference of said nosecone for bracing the latter with respect to the missile. 7. A missile having a jettisonable nosecone according to claim 1.
