  • BLAST ATTENUATION DEVICE
    Publication number: 20240093958
    Abstract: A blast attenuation device (100, 1100) for a gun tube (10). The blast attenuation device (100, 1100) has a first wall section (102, 1102) which defines a first chamber (104, 1104), which extends from an inlet end (106, 1106) having an inlet aperture (108, 1108) to an outlet end (110, 1100) having an outlet aperture (112, 1112). The blast attenuation device (100, 1100) also has a second wall section (122, 1122) which defines a second chamber (124, 1124), which extends from an inlet end (126, 1126) having an inlet aperture (128, 1128) to an outlet end (130, 1130) having an outlet aperture (132, 1132).

  • Muzzle brake
    Patent number: 11768050
    Abstract: A muzzle brake (20) for a gun tube (12) defining a bore (40) centred on a longitudinal axis (32). The muzzle brake (20) comprises a top plate (24) and a bottom plate (26). A first wall section (100), a second wall section (200) and a third wall section (300) extend from the top plate (24) to the bottom plate (26).The second wall section (200) extends from the first wall section (100) to a first baffle (220). The third wall section (300) extends from the second wall section (200) to a second baffle (320). The second wall section (200), top plate (24) and bottom plate (26) converge towards the longitudinal axis (32) and the first baffle (220), such that the second wall section (200), top plate (24), bottom plate (26) and first baffle (220) define a first compression cone (224).
