• Linear stage reaches end of travel• Roller (1) constraining CCR is free,

due to slot in roller track (2)• Preloaded, redundant torsion springs

(3) cause CCR rod to pivot upwards

CCR Deployment Sequence [3]

• Pivot Assembly reaches hard stop. Limit switch is triggered

• Pin Puller #2 is actuated, releasing the CCR Rod

• Nose Cone (3) contacts ground

• Puncture Rod (2) is pushed upwards. Tip punctures sealed gas cylinder (1)

• Gas is released from gas cylinder, exiting out the nose cone jets (4)

• CCR Rod plunges into the soil

CCR Rod is free to slide within the sleeve
