I give you the point that solids are slightly more simple than pressure fed. But I really don't think its by much. In both the tanks have to have higher pressure than the 'chamber' but solids the entire tank is the chamber and needs to withstand the vibrations and temperatures whereas pressure fed can be isolated from all that.

>Shit isp is not really a big deal for a booster/first stage.
This is rocket science bro, you get anything you can where ever you can.

>shit mass ratio (on liquids)
LOL nope.gif
Your tanks gotta be massive thick and ungodly. Pressure-fed liquid tanks are far lighter than solids. youz all but my fuel is heaver, yah its full of binders and inhibitors ya goof and we aint doing hydrogen here

>Far more rocket catastrophes have occurred due to liquid rocket malfunction than solid.
Nice, you got a red herrings on tap or some shit bro epic debate skillz. Firstly quantity =/= rate of occurrence. Secondly pressure-fed =/= pump fed liquids. I mean by your logic there has never been a catastrophe from a pressure fed liquid rocket so its gotta be the safest ever. Always remember the only astronauts ever killed directly by an engine failure where killed by solids. A solid fails its a fucking bomb, a liquid fails the engine shuts off and you fly home or what ever.

>>and they cost more to reuse than to build new ones.
>Any amateur rocketry enthusiast will tell you otherwise.
>I'm pretty sure your figure is double the actual figure.
45m for refurbished 40m for expendable more than 100m if you amortize the development cost, and what the fuck does it matter what an amateur rocketry enthusiast tells you about refurbishing armature rockets

lol too many anons to keep separated, pic for you Hampshire chan.

Because I love him, I want him to get me pregnant and transplant my babies into him. Wouldn't it be so cute.

Why not?
