CCR Deployment Sequence [1]
• CCR Deployment Mechanism in stowed position
• Pin Puller #1 is actuated, releasing the spring loaded linear stage
• Linear stage is on rollers for smooth deployment

• 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
5
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

• (Left) Non-contact position sensor is triggered at end of travel
• (Center) Pin Puller #3 is actuated, releasing spring loaded arms simultaneously
• (Right) CCR Rod continues to plunge into soil unhindered
