Spaceport Launch Complex Vertical Integration Cell Rig-In & Upender Audit

Pre-integration engineering audit protocol for transitioning heavy orbital rocket stages from horizontal SPMT roll-in to vertical launch mount docking: hydraulic upender synchronization, static bonding (<1Ω), and launch pad foundation integrity.

Phase 1: Roll-In Ingress & Structural Pad Interface

ROLL-IN

SPMT Roll-In Ingress Track Alignment & Threshold Transition (≤10mm Step)

Laser alignment verification across launch mount apron and high-bay roll-in door sill to prevent wheel shock impact.

Four-Point Earth Grounding & Dissipation Bonding (<0.5 Ω)

Install heavy braided copper grounding straps from booster forward skirt and aft thrust puck to launch pad earth grid prior to hydraulic disconnect.

Continuous Gaseous Nitrogen (GN2) Internal Tank Pressure Verification

Ensure 2.5 to 4.0 PSIG positive ullage maintained in propellant tanks during lock-in to prevent skin canning under hoist load transfer.

Phase 2: Upender Engagement & Horizontal-to-Vertical Rotation

ROTATION

Aft Thrust Puck / Hold-Down Post Collet Locking & Ultrasonic Pin Check

Full engagement verification of pneumatic collet locks on upender hinge pins with secondary mechanical dog safeties pinned.

Hydraulic Telescopic Cylinder Synchronization (±2mm Stroke Delta)

Proportional electro-hydraulic servo valves monitored to ensure dual multi-stage lift rams advance at matched velocities through the 0° to 90° arc.

Crane Forward Lift Ring Tandem Load Cell Interlock

Overhead 500t integration cell bridge crane tracking lifting bridle load share dynamically as weight shifts from horizontal to vertical.

Phase 3: Launch Mount Docking, Alignment & Release

MOUNT DOCKING

Launch Table Hold-Down Clamp Interface Laser Alignment (±1.0mm)

Multi-station laser tracker verification across 20 hold-down points on orbital launch mount prior to final stage touchdown.

Quick Disconnect (QD) Cryogenic Umbilical Plate Pre-Fit

Confirm liquid methane and liquid oxygen tail service mast (TSM) QD plates mate smoothly with zero mechanical binding on seal gaskets.

Full Load Transfer Sign-Off & Crane Release Protocol

Gradual crane load shedding at 10 tons/minute with hold-down load cell confirmation; removal of forward lifting bridle and rigging arms.

Integration Readiness Index
