  • Just how pointy does a rockets nosecone need to be?
    The Wikipedia nose cone design article that Hobbes links mentions that conic tips are often chosen for ease of manufacture over more complex shapes, and this was probably the driving factor for Qu8k This chart from that page shows that cones are actually poor performers in the transonic regime
  • What are the pros and cons of Aerospike nosecones?
    $\begingroup$ The round nosecone that the aerospike sticks out of is not the reentry body, so your sentence "Adding an aerospike to a big, round nosecone is a great solution to that problem "
  • Why was the nose cone on the Space Shuttles external tank pointy?
    The original External Tank nose cone design was indeed blunt - almost like a fireplug, as seen in this 1975 concept art [Image source - lost in the mists of time to me, but NASA somewhere] However, wind tunnel testing at the Arnold Engineering Development Center revealed that this configuration caused unsteady aerodynamic buffeting at some
  • Would Dragon reenter safely if the nose cone stayed open?
    There is a way to manually eject the nose cone, which is what would be done in such a situation Presumably this would limit reuse and increase the risk, but not ultimately be as risky as having an unclosed nose cone Note that Crew Dragon reentering with no nose cone is pretty similar to the original Cargo Dragon
  • Is this egg-shaped nose cone a good, aerodynamic design?
    The Falcon 9 fairing nose is a blunted cone (no escape system) The Falcon 9 hoisting a crew Dragon2 has a mostly-cone with a rounded nose (escape system mounted on the sides, which is part of why it's not a smooth cone shape) The Soyuz nose is pointy, because like the Saturn V it has a very pointy launch escape system
  • apollo program - Why does this rocket have a nose cone cozy? - Space . . .
    Why does the nose of the rocket shown in Apollo-era file footage used in this video (lower your volume before watching) have a thick cover that's pulled off about eight seconds before launch? note: as in the video in the as-yet unanswered question Is this one coherent set of images or a mixture of several missions? it appears that the footage
  • Why not jettison the nose-cone from Falcon Heavy side boosters for . . .
    throwing away the nose cones, and adding another separation event, making sure the nose cone doesn't hit the stage after separation, etc This seems to me to be the more complex (=expensive) choice Throwing away the nose cones also means another item that needs to be rebuilt every time a stage is reused, and more work in refurbishing the stage
  • falcon 9 - Dragon launch escape: is nose cone ejected for parachute . . .
    In normal operations, I believe the nose cone is ejected prior to atmospheric reentry, but on launch escapes the nose cone would be locked shut The opposite is true: the nose cone is open until after the deorbit burn, since the deorbit burn uses the Draco thrusters mounted in the nose cone The nose cone hatch is closed after the deorbit burn
  • spacex - Why the soot pattern on the nosecone of Falcon Heavy side . . .
    We do know from the question On the Falcon Heavy, why are the side boosters using Ti Grid fins, but not the center core? that there appears to be aerodynamic consequences to the use of a streamlined nose cone, as opposed to the larger longer interstage that a single stick booster landing would have its end
