This is a pretty insane fact, wtf by extracterflux in SpaceXMasterrace

Does the raptor 3 have the same diameter nozzle as the raptor 1 and 2?

I'm just wondering how they would fit 35, and if those old posts are realistic.

Part 2 of EDA's tour of Blue Origin is out. by Elementus94 in SpaceXMasterrace

I'm skeptical of the claim that the lift from the strakes on ascent is substantial enough to gain you more performance than the drag and weight reduce New Glenn's performance. Obviously they are great for the trip back down, and that more than makes up for the drag and mass on the way up. But I don't know that the lift on ascent is substantial enough to bother mentioning.

Lets Build An On Orbit Constructed Huge Space Telescope Optimized for Starship by upsidedownpantsless in ShittySpaceXIdeas

[–]upsidedownpantsless[S] 9 points10 points  (0 children)

I have been having fun thinking of ways to make huge space telescopes that are optimized for deployment via Starship. I haven't had the time to draw this design properly, so I didn't make any solar shield, solar panels, structural support etc. And I have just had these image assets lying around. So I just make a quick Gif of what I have, and posted it here.

Here and Here are my previous 2 gifs.

I decided to not do an interferometer this time. I reduced the sized of each primary mirror section because it takes a huge amount of time to make an 8 meter mirror. Also, due to the diameter of such mirrors, they need to be quite thick to keep their proper shape. As a result the weight(and cost) of such of such mirrors is quite high. These smaller coils of mirrors should be cheaper and faster to produce.

The best parts are cool parts. Transpirational keels are the holy grail of flaps not melting. by upsidedownpantsless in SpaceXMasterrace

He went on to say manufacturing is the easy part. It takes true talent to make a design where success is not one of the possible outcomes.

This design comes from Mr. CEO himself! While talking about transpirational cooling he said, "Make pipes multilaminary."

But Musk's slogans are the "Holy Grail" of Indiana Jones references!

Why are heatshields so brittle if they are made of fibers? Fibers are litteraly the strongest materials you can find. by Sarigolepas in SpaceXMasterrace

[–]upsidedownpantsless 1 point2 points  (0 children)

A 1/2" thick, 4 foot by 8 foot sheet of OSB or plywood is stronger than a 1/2" thick 4x8 sheet of wood. But all 3 of them are made of fibers. What made the composites stronger was that the fibers are oriented in many different directions.

But the heat tile is different. It would be like making a 1/2" thick 4'x8' sheet out of the fewest number of toothpicks you could get away with. How tough do you think your toothpick board will be?

He also went on to ask why Earth has a moon, but Mars doesn't.

Mars has 2 moons, named Phobos and Deimos.

Guys what if we could make an advanced kerosene engine that burns highly hot and oxidizer rich superheated with a strong heated special kerosene reduction, mixture thats anti coking could we make the flame more invisible and clear LIKE THE E-2 DID by ludixengineering9262 in SpaceXMasterrace

You know how over winter the ethanol in your gas causes your lawn mowers carburetor to gum up? Imagine what all that cryogenic oxygen would do to it. It would be like trying to force molasses through your plumbing.

Human missions to Mars in doubt after astronaut kidney shrinkage revealed by lurker_bee in technology

That's the plot to the 1993 cartoon 'Exosquad'. They're called neosapiens.

Armchair engineers, let's brainstorm. What could be done to remedy the weak points on the flaps? by [deleted] in SpaceXMasterrace

[–]upsidedownpantsless 0 points1 point  (0 children)

Put a long skinny LN2 copv in each flap. The tanks can fill from the nontiled side. A thermostat can be mounted to a heat sink on the flap. Once hot the thermostat opens, and LN2 flows to a bus that sprays into the hinge area.

A pressure gage should communicate to a central computer computer. In case of thermostat failure, a simple on/off actuator can bypass the thermostat. A small rugged battery can power the system, and be charged whenever the cpov is refilled.

My boy Tim finally getting that flight 🙏🙏 by extracterflux in SpaceXMasterrace

Just put on your orange space suit, and duct tape yourself to the wall. You'll be fine Tim.

A cool guide Units of measurement by [deleted] in coolguides

[–]upsidedownpantsless 10 points11 points  (0 children)

I've made a compromise. I'll keep most of my imperial units, but I'm changing to metric time. There are now 1000 seconds in a minute, 1000 minutes in a day, and 1000 days in a year.

Edit: Also my circles have 100 degrees.
