Hallo,
mutig sind sie ja schon bei SpaceX. Hier ist die Liste aller Neuerungen, die beim nächsten Flug eingeführt werden. Ich glaube nicht, dass es jemals so viele (große!) Änderungen zwischen zwei Flügen gegeben hat.
Grüße
Maximilian
Super Heavy V3 Changes
Grid Fin Redesign:
• Reduced from 4 fins to 3,
• Each fin is now: 50% larger, stronger, repositioned for better catching/lifting,
• Lowered on booster to reduce heat exposure during hot staging,
• Fin hardware moved inside fuel tank for protection.
Integrated Hot Stage:
• Removes the old disposable interstage shield,
• Booster dome now directly exposed to upper-stage engine ignition,
• Tank pressure + steel shielding protect structure,
• Interstage actuators retract after separation for protection.
New Fuel Transfer System:
• Massive redesign of fuel transfer tube,
• Roughly the size of a Falcon 9 first stage,
• Allows: simultaneous startup of all 33 Raptors, faster and more reliable flip maneuvers.
Engine Bay / Thermal Protection Changes:
• Engine shrouds removed entirely,
• New shielding added between engines,
•Propulsion + avionics more tightly integrated,
• CO₂ fire suppression system removed,
• Simpler and lighter aft section.
Propellant Loading Improvements:
• Moved from 1 quick disconnect to 2 separate systems,
• Adds redundancy,
• Reduces complexity of pad interfaces.
Starship V3 Changes
Completely Redesigned Propulsion System:
• Clean-sheet redesign,
• Supports: new Raptor startup method, larger propellant volume and improved reaction control system,
• Reduces trapped/leaked propellant risk.
Aft Section Simplification:
• Fluid + electrical systems rerouted,
• Engine shrouds deleted,
• Large aft cavity removed.
Flap Actuation Upgrade:
• Changed from: 2 actuators per flap to 1 actuator with 3 motors,
• Improves:, redundancy, mass efficiency, cost.
Faster Starlink Deployment:
• Upgraded PEZ dispenser,
• Faster satellite deployment speeds.
Long-Duration Spaceflight Capability:
• New systems added for: long orbital coasts, orbital refueling, cryogenic fluid management, vacuum, insulated header systems and high-voltage cryogenic recirculation.
Ship-to-Ship Docking + Refueling:
• Added 4 docking drogues,
• Added propellant transfer connections,
• Directly supports in-space refueling architecture.
Avionics Upgrades
Massive Electrical System Upgrade:
• ~60 custom avionics units
• Batteries/inverters/high-voltage systems integrated together
• ~9 MW peak power capability
Better Navigation + Redundancy:
• New multi-sensor navigation system,
• Designed for precision autonomous flight.
Propellant Monitoring in Space:
• New RF sensors measure propellant levels in microgravity,
• Important for orbital refueling missions.
Camera + Connectivity Upgrades:
• ~50 onboard camera views,
• 480 Mbps Starlink connectivity onboard,
• Low-latency redundant communications.
Raptor 3 Engine Changes
Higher Thrust:
• Sea-level Raptors: • Increased from: 230 tf → 250 tf 507k lbf → 551k lbf,
Vacuum Raptors: Increased from: 258 tf → 275 tf 568k lbf → 606k lbf
Lower Mass:
• Sea-level engine mass reduced: 1630 kg → 1525 kg.
Simpler Design:
• Sensors/controllers integrated into engine body,
• Removes need for engine shrouds,
• New ignition system for all variants,
• Huge Vehicle-Level Weight Savings,
• ~1 ton saved per engine across vehicle systems.
Launch Pad 2 Upgrades (Starbase)
Faster Propellant Loading:
• Larger propellant farm,
• More pumps,
• Faster fueling operations.
Chopstick Improvements:
• Shorter arms for faster movement,
• Switched from hydraulic → electromechanical actuators,
• Better reliability + redundancy.
Stronger Quick Disconnect Arm:
• Reinforced and redesigned,
• Swings farther away during launch.
Launch Mount Redesign:
• Better load handling,
• Improved launch protection,
• Improved throwback reliability.
New Flame Diverter System:
• Bidirectional flame diverter,
• Designed to eliminate ablation/refurbishment after launch.
Hardened Propellant Systems:
• Methane and oxygen systems separated,
• Valves/filters moved into protected bunker,
• Improves safety and reliability.
