Extractor

Mosmoni CR-3722-RP aerostat extractor platform operating within the Venusian lower cloud deck (~50 km altitude).

Overview

The Harvester is a heavy industrial aerostat platform designed for continuous atmospheric extraction, processing, and aerial logistics operations within the temperate band of Venus’s atmosphere (45–60 km altitude).

Manufactured by Mosmoni Heavy Industries, the rig serves as a multi-role installation combining:

• Atmospheric resource extraction
• Flight deck operations
• Station-keeping and regional traffic coordination
• Defensive and surveillance capabilities
• Long-duration crew habitation

The platform is optimized for sustained operation in high-wind, corrosive, and electrically active atmospheric conditions.

Structural Layout

The aerostat is built around a reinforced central spine supporting:

• Habitation decks
• Processing plant
• Power systems
• Structural load paths

The lift section is mounted above the operational mass, improving:

• Stability (pendulum damping)
• Weather alignment (weathervaning)
• Reduced roll and pitch coupling

Major Sections

• Lift Envelope (Upper Section)
• Central Spine (Core Structure)
• Flight Deck and Hangar
• Atmospheric Processing Plant
• External Intake Assembly

Crew and Habitation

The platform operates continuously using a three-watch rotation system.

Crew Breakdown (Typical)

Department	On Duty	Total (Approx.)
Bridge / Command	6	18
Flight Operations	10	30
Processing Plant	5	15
Engineering / Trim	3	9
Security / Medical / Misc	4	12

Habitation Model

The rig uses a hot-bunking system to reduce required volume.

• 2–3 personnel assigned per rack
• Separate locker bays for personal storage
• Shift-based occupancy rotation
• Centralized habitation within protected spine

Habitation Facilities

• Rack rooms (shared, 4 bunks per room)
• Locker bays (external to sleeping areas)
• Galley and mess hall
• Hygiene blocks ("heads")
• Medical bay
• Emergency citadel (sealed refuge for full on-duty crew)

Bridge and Command Operations

The bridge functions as the platform’s:

• Navigation center
• Tactical control
• Airspace coordination node

Responsibilities

• Station-keeping relative to wind and neighboring platforms
• Traffic management (approach/departure sequencing)
• Sensor monitoring (radar, atmospheric, threat detection)
• Defensive systems authorization
• Emergency coordination

Typical Watch

• Watch Officer (Command)
• Helm / Station-Keeping Operator
• Sensor / Tactical Operator
• Communications Controller
• Systems Monitor (Engineering liaison)
• Air Ops Coordinator (if integrated)

Flight Deck Operations

The harvester supports continuous aerial operations.

Capabilities

• VTOL/STOL aircraft launch and recovery
• Elevator-based hangar integration
• External cargo handling (cranes, rigging)
• Emergency recovery (damaged craft)

Deck Crew Roles

• Air Boss (deck authority)
• Landing Controller
• Launch Controller
• Deck handlers / rigging crew
• Fueling and turnaround technicians

Operational Notes

• Deck operations are heavily influenced by wind shear and turbulence
• Approach corridors are dynamically adjusted based on atmospheric conditions
• Arresting and guided landing systems (e.g., "Autoflyte") may be employed

Atmospheric Processing System

The defining feature of the CR-3722-RP is its atmospheric extraction capability.

Intake System

A large lower-mounted intake draws in Venusian atmosphere:

• High-volume CO₂ intake
• Aerosol capture (sulfuric acid droplets)
• Multi-stage filtration and compression

Processing Functions

• Molecular separation (CO₂ → O₂ extraction)
• Hydrogen recovery (via chemical processing loops)
• Trace element capture
• Gas refinement for buoyancy and life support

Outputs

• Oxygen (breathable / industrial)
• Hydrogen (lift gas replenishment)
• Industrial feedstock gases
• Waste heat (significant)

Lift and Buoyancy System

The platform maintains altitude using a combination of:

• Hydrogen-filled lift cells
• Controlled gas compression and expansion
• Ballast and trim management

Stability Features

• High-mounted lift section for pendulum stability
• Distributed buoyancy cells for redundancy
• Active trim control (mass shifting, gas redistribution)

Station-Keeping and Propulsion

The platform is not an aircraft but maintains controlled positioning.

Methods

• Vectored thrusters
• Process gas exhaust redirection
• Buoyancy adjustments
• Aerodynamic alignment (weathervaning)

Performance

• Relative movement vs air mass: ~5–20 km/h typical
• Primary function: formation keeping, drift correction, spacing

Defensive Systems

Due to piracy and territorial conflict, platforms are typically equipped with:

• Radar and sensor arrays
• Close-range defensive weapons
• Electronic countermeasures
• Shield emitters
• Hardened internal citadel

Security personnel maintain:

• Boarding defense readiness
• Internal threat control
• Access control to critical systems

Environmental Hazards

Operations at ~50 km altitude on Venus expose the platform to:

• High-velocity winds (~200+ km/h)
• Sulfuric acid aerosols (corrosive)
• Lightning and electrical discharge
• Thermal gradients
• Structural fatigue

Radiation levels are not considered a primary hazard due to atmospheric shielding.

Emergency Systems

Citadel

A hardened internal refuge capable of sustaining the full on-duty crew:

• Independent air supply
• Sealed environment
• Emergency rations
• Command link to bridge

Redundancies

• Multiple power paths
• Compartmentalized bulkheads
• Fire suppression systems
• Decontamination zones

Operational Doctrine

The CR-3722-RP is designed for:

• Continuous industrial extraction
• Persistent regional presence
• Cooperative or competitive aerostat networks
• Support of aerial trade and combat operations

It functions as both:

• A stationary industrial asset
• A strategic node in aerial logistics and conflict zones

Notes

• Crew endurance and morale are heavily influenced by hot-bunking and confined living conditions.
• Platforms often develop distinct internal cultures and informal hierarchies.
• Long-term deployments may lead to psychological and interpersonal strain.
