  1. Operation Sledgehammer

    A11 please
  2. You can change me to I66. I will take the CO position.
  3. I44 please

    Its just extra air that the compressors do not need, The air is reverse through the bleed valve then would be compressed back through if needed. BTW that butterfly valve is a pain to replace

    Is an automated system for prolonging the life of the engine, by maintaining a free flow of air; this is accomplished by sequentially back-flushing the air cleaner assembly intake filter elements. The PJS consist of an Air Supply Line (used when the engine is running, to provide air from the engine), an air pressure accumulator (located in the plenum), a vacuum switch (located between the intake filter elements and the engine), nine PJS solenoids attached to the air pressure accumulator installed in the engine intake plenum, element dividers, the scavenger duct and fan, and a PJS Pulse Control Unit is located in the hull near the hydraulic reservoir. When vehicle master power is turned on, the PJS Pulse Control Unit (PCU) begins to monitor engine RPM. The first time engine speed exceeds approximately 1500 RPM, the PCU will start a timer. When the accumulated engine run time above 1500 RPM reaches two minutes, the PCU will activate the PJS. This two-minute timed initialization period occurs only once per PCU power up. Engine bleed air is used to charge an accumulator, located inside the plenum, to approximately 200 psi. Attached to the accumulator are nine PJS solenoids. Three solenoids are used for each intake filter element. Each solenoid is sequentially activated for a period of 100 milliseconds at approximately 10 second intervals. Upon activation, a solenoid directs a high pressure air pulse into an intake filter element. Activating all nine solenoids in sequence is consideredone cycle of operation. These high pressure pulses of air cause a momentary reverse air flow through a portion of the intake filter element in line with the solenoid. This blows out dust or dirt accumulations from that portion of the intake filter element. Any dust or dirt blown out falls to the bottom of the air box and is scavenged out through the scavenge ducts. The system initially starts in the low clean mode. The low clean mode consists of three cycles of pulses (27 total) repeated at approximately 15 minute intervals. Any time the PCU monitors an engine speed below 1410 RPM for longer than 10 seconds, pulsing will cease. If the engine speed goes back above 1500 RPM, the PCU will resume operation at the point in the cleaning cycle where it left off. During operation, the PCU monitors the level of flow restriction through the use of a vacuum switch located between the intake filter elements and the engine. Whenever the vacuum level reaches approximately 19 inches of water, the vacuum switch will open. At this signal, the PCU will switch to a high clean mode. The high clean mode will be maintained until the flow restriction decreases to the point where the vacuum switch closes. The vacuum switch will close at approximately 12 inches of water. The PCU rechecks the state of the vacuum switch each time two cycles of pulses are completed. During the high clean mode, the PCU will continuously pulse all nine solenoids sequentially at approximately 10 second intervals. There is no 15 minute delay intervals between every third cycle in the high clean mode. When the high clean mode signal is no longer present, the PCU will end the high clean mode with three final cycles (27 pulses).

    No Problem, during that video it was in low clean mode, If it switched to high clean there would be dust and dirt coming out constantly.

  9. I'll say the M1A2 SEP's Ballistic Computer is working just fine. https://youtu.be/ohCUz2sFv54
  10. Colebrook maybe one of us or someone here like Gibsonm can meet up with him on teamspeak and watch him shoot a few rounds to see what’s exactly happening. I sent him a PM already
  11. The M1A2 in SB is the M1A2 SEPV2 baseline. I also did some Gunnnery practice last night with the M1A2 and was hitting all targets both with Sabot and Heat (M830) on the range. Using the “Insert” key for Sabot and the “Delete” key for HEAT (M830) indexes.
  12. The SEP defaults to MPAT which is the “END” key for custom missions. In the Gunnery Range it actually has the HEAT loaded which would be the “Delete” key. You can adjust the ammo positions and ammo in the mission editor.
  13. Are you hitting targets with Heat on the Gunnery Range?
