Name the motors

MK66 MOD2, weight, thrust time, igniter

-HERO susceptabil

-Only used in LAU-61 C/A

-Avg Thrust 1,360lbs for 1.1 sec, 13.65lbs

-MK125 5 ingniter and tubular stabalizing rod with 5-wire HERO filter strung through rod

MK66 MOD4, igniter type

-HERO safe & hot tube loaded

-Contains solid stablizaer rod, MK 311 igniter + a set of filters in the igniter and a single filter under the nozzle contact band.

How does the motor work

The motor is ignited by 28-Vdc aircraft power distributed by the launcher intervalometer. Gas pressure resulting from the burning igniter charge ruptures either the igniter case (Mod 2) or igniter vent hole seals (Mod 4) and ignites the propellant grain. The propellant burns from inside to outside to minimize cg shifts. Propellant gases rupture the nozzle seal and exert forward pressure (motor movement) that overcomes the launcher tube locking detent. The stabilizing rod in the center of the propellant grain, prevents unstable burning of the grain The wrap-around (WAFFAR) fins on the Mk 66 2.75-inch motors are spring actuated to open and seat in the nozzle body fin slots as the motor exits the launcher tube.

Primary difference between LAU-130 & LAU-61

the LAU-130 lacks the LAU-61’s thermal protective coating.

The LAU-61 surface will appear to have a foam-like coating with a pebbly texture, while the LAU-130 will have smooth, painted metal

The primary difference between the LAU-68C/A and LAU-131/A and the LAU-68D/A is that

the LAU-68C/A and LAU-131/A lack

the thermal protective coating of the LAU-68D/A. As such, The LAU-68C/A and LAU-131/A are

not approved for ship-board use
