Q & A
What significant changes has SpaceX made to the Starship program since its first launch in 2023?
-SpaceX has made several upgrades to the Starship program, including modifications to the nose cones, the design of the oxygen and methane fuel tanks, changes to the flaps, and improvements to the heat shields and thermal protection system. They have also introduced new versions of Starship, V2 and V3, with V3 expected to have over 10,000 tons of thrust and double the payload capacity of V2.
How have the nose cones of the new Starship variant been redesigned?
-The new nose cones are slimmer and longer compared to the previous ones, with streamlined lifting points reduced from six to four, potentially creating more balance when lifting and reducing attack surfaces.
What is the purpose of the new slanted design of the liquid oxygen and methane tanks?
-The slanted design includes an integrated funnel, which could be related to managing fluids both horizontally and vertically, ensuring stable fuel flows at all stages of flight. It also improves efficiency by allowing the use of the entire volume of the manifolds.
What adjustments were made to the flaps of the Starship after the fourth launch?
-The position of the flaps has shifted towards the leeward side, forming an angle of about 140° instead of the previous 180°, to avoid direct impacts during re-entry. The flaps have also been moved closer to the top of the ship and are smaller and sharper in shape.
How has the thermal protection system of Starship been improved?
-The new heat shields are twice as durable as the old ones and have an additional layer of insulation. The heat shield on the nose cone has been extended for better protection, and the flaps have reduced mass for increased agility and improved navigation efficiency.
What are the differences in height between Starship V1, V2, and the proposed V3?
-Starship V2 is 3.1 meters taller than V1, while V3 is expected to stand about 150 meters tall, which is significantly taller than both V1 and V2, and may even exceed the height of the current launch tower.
What is the expected thrust improvement from Starship V1 to V3?
-The expected thrust improvements are from 7,000 tons for V1 to over 8,000 tons for V2, and V3 could potentially exceed 10,000 tons of thrust.
How does the hot staging of Starship V2 and V3 differ from V1?
-Instead of the original vent design, the new version of Starship will have an interface similar to the N1 style interstage of the Soviet Union, integrated into the ship, which has sparked debate about the increased gravitational forces and pressures during flight.
What is the significance of the Raptor V3 engine in terms of SpaceX's design approach?
-The Raptor V3 engine represents a comprehensive redefinition of rocket engine design, with integration of components, removal of the external heat shield, focus on reducing the number of sensors, and improvements in specific impulse, all contributing to a more reliable, lighter, and higher performing engine.
How has SpaceX addressed the challenge of accessing internal components of the new Raptor V3 engine?
-SpaceX has acknowledged that in some cases, the only way to access internal components is to cut the engine open, which is a trade-off they are willing to accept for optimal performance.
What is the total weight of the Raptor engine system on a Super Heavy Block two or V2 booster?
-The total weight of the engine system, including related hardware, is about 60 tons, which is over a quarter of the total weight of the whole booster.
