Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A recoil-actuated gun scavenger for a gun having a bore, a breech, a recoiling mass, and a non-recoiling mass. The scavenger may include a pneumatic cylinder and a piston translatable therein. A rod may be fixed to the piston. The cylinder and rod may be fixed to respective recoiling and non-recoiling masses, or vice versa. The cylinder may include intake and exhaust ports with check valves, on both sides of the piston. The exhaust ports may communicate with an accumulator. The accumulator may discharge compressed air to jets located at the open breech end of the gun.

Abstract: A composite gun barrel 10 with active cooling having a breech end and a dharge end. The barrel includes an outer jacket 11 having radially inwardly projecting ports 15 proximate the breech end 25 extending inwardly from the outer diameter of the jacket, and an inner liner 13 inside the jacket and extending beyond the discharge end of the jacket prestressed by autofrettage to form a permanent integral assembly. The inner liner has a circumferentially located annular space 17, the ports being in operable communication with the annular space. A plurality of circumferentially spaced longitudinal channels 19 on the liner extend from the annular space to a location 21 beyond the discharge end of the jacket. The liner includes a shoulder 23 located between the breech end of the barrel and the inwardly projecting ports for locating the jacket on the liner.

Abstract: A gun bore evacuator comprised of a main reservoir surrounding the gun tu a bore in the tube, ports between the main reservoir and the bore, an auxiliary reservoir surrounding said tube, ports between said main reservoir and the bore, ports between the auxiliary reservoir and the bore, and check valves between the reservoirs.
