A.h.c. the most primitive spaceflight possible page 2 alternate history discussion electricity quotes by benjamin franklin

Basically the technologies I think we need are gunpowder (of course) steel (for the electricity nw gun barrel and the capsule, I’m going with a space-gun design), an ability to measure fine tolerances (something like a micrometer), precision timekeeping (so something like Harrison’s chronometer) and a parachute (so some basic ideas of aerodynamics). Here’s my concept:

So we have thitima electricity sound effect a multistage gun barrel built into the side of a big mountain. The Alps or the Khingan range are good places to go with. The bottom of the gun is dug into the mountain so we can get a launch angle of 60 degrees or so. Each stage will fire at a timed moment after the last one, we need several stages to avoid killing our astronaut with the acceleration. The width of the barrel should be about a meter, only slightly larger than the largest cannons built historically.

Then we have gas house gorillas our projectile, I imagine something a meter wide and about 2.5 meters long, to fit everything. The sides of our projectile are about 8 cm thick steel, with a small thick glass windowpane (probably like 12 cm thick, with the steel widening at that point monroe la gas prices to hold it). At the very top is a contained portion of water with pressure valves that will let steam escape when the pressure gets to 5 atm or so. Below this is a hatch that allows the top of the projectile to be disconnected and tossed away, and a location for our parachute all folded up, with hooks to attach its gas near me cheap ropes to the inside of the projectile. Below this is our crew quarters. Here our astronaut (we want someone short and small I think, a little person or a petite woman, though whether the launching electricity flow diagram society will go for this is debateable) is strapped in for launch, wearing a thickly padded suit of linens to absorb as much shock as possible. They are probably in a sitting position with their knees tucked upwards and their head down in a crash position. The walls are padded with a layer of wet cotton, both as a heat sink and as a shock absorber. Carried with the astronaut is a sketchpad for electricity vs magnetism observations and levers which can be pulled to release spring-loaded fins from the sides of the projectile (this will ensure it falls down bottom-first). Below this is a bottom portion much like the top, with water and pressure valves.

So we put the astronaut in the projectile (with hatch open gas hydrates ppt a crack, probably, so air doesn’t start getting short before launch). Then load the projectile in the space-gun. Then batten the hatch, brace for launch, and FIRE! The boiling-off water at the electricity kwh cost uk top acts as a heat sink to keep the projectile from burning up as it rushes through atmosphere, and in a couple minutes gas vs diesel cars it’s at 100 km. Our astronaut, assuming they survived and didn’t pass out, will now activate the fins and start sketching observations before they hit atmo again in a couple minutes. Then hunker down for re-entry, hope the bottom heat sink avoids the projectile burning up, and once the ground is getting close enough hook the ropes of the parachute to the sides of the projectile. Then open electricity per kwh calculator the hatch, toss the parachute out, and pray… and if all goes well, land in some farmer’s field having been the first human in space.
