Question 35

How does the M485A2 work? (long boy just blue it, bookmark it and read 2 mins before the test lol)

Answer 35

fuze functions and the Primary Expelling Charge is ignited. expelling charge generates gas pressure and ignites the delay composition in the Delay Holder gas pressure builds up until it is sufficient to cause the shear pins at the base of the projectile to fail. shear pins fail the contents of the projectile are ejected rearwards Drogue Parachute Assembly deploys, bringing the complete internal assembly into a vertical plane four spin retardant fins deploy, slowing down the rotation After approximately eight seconds the delay composition burns through and ignites the Secondary Expelling Charge. secondary expelling charge ignites the main illuminant candle and expels the candle along with the main parachute. The burning candle descends beneath the deployed main parachute
