摘要:
Protection device (8) for a rocket launcher comprising a cover (5) which includes a triplet of openings (6) arranged in angularly equidistant positions so as to allow the passage of the rockets (R) housed in two alternating triplets of rocket housings (3A or 3B). The protection device further comprises actuation means (9) designed to rotate the cover (5) between a first position in which the triplet of openings (6) is aligned with the first triplet of openings (3A) and a second position in which the triplet of openings (6) is aligned with the second triplet of housings (3B).
摘要:
Device for the hold-down and controlled release of space satellites installed on launchers and loads installed on space satellites, comprising a blocking member (5) made up of segments (4) radially displaceable from a mutually approached retaining position to a mutually spaced-apart release position of a connecting screw (6). In order to control the radial displacement of the segments (4) between the retaining position and the release position there are provided a rotatable element (16) coaxial with the blocking member (5), an articulated mechanism (3) which operatively connects the rotatable element(16) with the segments (4) of the blocking member (5), and linear motors (23, 24) for driving the controlled rotation of the rotatable element (16) and, through the articulated mechanism (3), the simultaneous displacement of the segments (4) of the blocking member (5).
摘要:
Mechanism for restraining and releasing an external airborne load through pneumatic ejection wherein the load supports are made hollow so as to form a tank for the compressed air. The load supports consist of monolithic metal bodies made using an additive manufacturing process.
摘要:
The piloting section (3) of the solenoid valve is integrated with the valve section (5) and it includes a tubular stem (11) having a distal end (20) placed in communication with the atmosphere and axially displaceable by means of the solenoid (20) from a receded position, in which the shutter (7) of the valve section (5) is kept in the closing condition, to an advanced position corresponding to the opening condition of the shutter. The shutter (7) comprises a hollow plunger (12) coaxial with the tubular stem (11) and defining an inner thrust chamber (13) in which, in operation, in the receded position of the tubular stem (11) a fluid pressure - which keeps the shutter (7) in closing condition and which is released into the atmosphere - is applied to displace the shutter to the opening condition, through the proximal end (21) of the tubular stem (11) when it is displaced by the solenoid (10) to the advanced position.

摘要:
Container (1) for housing and launching sonar buoys of class G (sonobuoy) (2, 3) comprising a casing partitioned into two portions (4, 5) and automatic and simplified valve means (14,15) to sequentially eject the buoys (2,3) from the container (1).
摘要:
Pneumatic actuator designed to dispense a predetermined volume of compressed air from a main tank (2) to an outlet (13) of a solenoid valve (4). The actuator comprises a secondary tank designed to contain such predetermined volume of compressed air. The secondary tank is placed in communication with the main tank through a narrow duct (7) having a through-flow section much smaller than that of the outlet (13) of the solenoid valve (4).
