Looking at the different noses the cars sport, we can roughly categorize the noses in several groups:
We Have the thumb nose, as used by Ferrari, Renault, Toro Rosso, Haas and Williams and a very similar design on the Racing Point. It's the most common design which I think implies that it has the most favorable aerodynamic qualities, especially when you do not have the money to optimize it completely, its the "safe" option.
We have the rounded nose, as used by Mercedes. I don't know why only one team uses it, especially when that team rakes in the best results of the field. So I think it's very difficult to implement that design into an existing one, and something not feasible midseason. Maybe we will see another one in this category next season.
And finally we have the nose design I'd call the Vacuum Cleaner Design, used by Alfa Romeo, Red Bull and McLaren.
While most noses have a slight opening in the front, the noses of the latter cars take that design philosophy a new level, with almost comical looking openings in the front. The design seems to be pretty radical and experimental, but still the cars are raking in good results, especially RedBull and McLaren compared to the rest of the midfield.
I know there aren't any many Aero Engineers on here, but my question is: How does the vacuum cleaner design work? What is it doing differently and how is it affecting the car?
I am a beginner when it comes to cfd. I really want to do some simulations to find out which should be the best shape of a nose cone in rockets. Please tell me how to get started.
Been trying to come up with models but they dont seem right. Youtube fails short of what the top teams have for nose cones as well. Any help is appreciated
Newbie here, I’ve just finished building my first rocket and I have a question. When I put the nose cone on the body, it fits pretty loosely. If I turn the rocket upside down the nose doesn’t fall off but (when it’s upright) there’s a small gap between it and the body. I read on the instructions that I should put some masking tape if it’s too loose but with a layer of it on I worry it might be too tight? I have to twist it a bit to put it in or get it out. So, masking tape on or off? Any general advice about how to know if it’s too lose or tight, apart from turning it upside down?
Oh and, completely unrelated, but on the Estes instructions, in the launch part it says that I should put some masking tape around the launch rod close to the base, in like a “flag” shape. I didn’t read this anywhere else though, and I never see anyone mention it in videos so I was wondering if I have to put it and what’s its use is. I’ll link the instructions here: https://estesrockets.com/wp-content/uploads/Instructions/001469.pdf
Anyone have a good recommendation on where to find some good 37mm stuff to print? I don’t seem to have much luck with google
This design is a 3D model, that you can download for free from Thingiverse and print, of the Estes BNC-30D nose cone (part number 070244) that is designed to fit Estes BT-30 tubing. There are three models – the nose cone, the nose cone without the shoulder attached, and the end cap with a hole for the use of a screw eye or an eye bolt.
Estes models that were designed for this nose cone:
Kit # Kit Name
K-1 / 1201 Scout
K-15 Sprite
TK-4 / 0804 Hornet
0878 Scout III
1959 Scout II
You can download that model along with other models that fit Estes BT-5, BT-20, BT-50, BT-55, BT-60, BT-65, and BT-80 tubing.

For example, in a configuration for human occupancy, there's all the environmental systems, the seats, the control panels, etc... Do you expect all that to be installed in a nose cone that's not yet attached to the body?
On the one hand, it must be easier to mate an empty nose cone to the body. If the header tank remains in the tip of the nose then connecting its plumbing is easier. It seems to me that's enough of a reason to choose this order of operations.
On the other hand, there could be parallel tracks where one is furnishing the nose cone while the other is building the rest of the body. They meet for assembly when both are finished. Parallel tracks are a time saver on assembly lines.
Since the booster depot doesn't need to launch any payload, it might be able to SSTO. One less starship required, and it holds more volume as depot compared to a starship. One drawback could be the additional raptors used that would be sitting idle in orbit. Thoughts?
Most people pick their nose with their fingers, but I haven't done that literally in years. Not only is it unsanitary, very rarely will you get out all the boogers. I find if you roll a piece of tissue paper into a cone or point and stick it up there, the texture of the tissue is better at attaching itself to snot than skin. I always get back more, sometimes a long string of booger that clears your nasal passage.
I haven't found any by searching online - I'm looking to get streamers with a custom design (not size, that's easy enough, rather like designs with a logo) and also for HPR to change out the tip of my nose cone to something like inconel or titanium - not because I need to, I'd just like to own a useful piece of inconel.
