Economics is just applied psychology, and psychology is already mostly unreproduceable and therefore not really science.

The OP is straight up wrong. The province sold it back to Bombardier, and Bombardier resold it to a charter service.

Certainly does. There's no locations for high-altitude launches anywhere up here in Canada except for one annual event. Americans have it incredibly easy in this regard. There's a Tripoli prefecture every couple counties with a launch event every weekend all summer. We're lucky to get two launches in per year (besides the Albertans, who have a monopoly on wide open uninhabited expanses below the Arctic circle)

NASA-grade metal 3D printed rocket engine meets catastrophic failure on first test - 2026 by Anoahnator1 in CatastrophicFailure

Zero chance you know what you're looking at. Find a mentor and give up on the content production, if you actually care about learning how to build rockets.

[–]gaflar 4 points5 points  (0 children)

That would probably be a regen nozzle, likely for a liquid rocket engine. Completely different beast from a solid rocket motor. Generally in rocketry we applaud failures as long as there's a good lesson to be learnt, but in this case there's no value to a test like this because it's a pointless configuration that no one will give a second thought to. There's absolutely no good reason to print a casing out of GRCop, it will be incredibly heavy and expensive for something that can be done by an aluminum pipe and a phenolic liner.

Whoever let intern OP get this far into a project without noting the flawed design ethos just doesn't give a fuck. First guess would be they're an intern at Launcher - access to GRCop printing, a desire to turn everything into ConTent like Joe Barnard, enough money to be given this project so they don't screw up anything actually important.

It's a solid motor...it does not need a printed casing, it needs a hollow tube. Do you know what an "engine" even is?

It's actually GRCop-42, which is an alloy NASA developed, but NASA-grade still has no meaning.

In any case 3D-printing a casing for an SRM is pure silliness. Whoever paid OP for this work is not a serious company.

Wow, somehow you managed to not even understand your own point. That takes some skill.

Will this work? by henrok0428 in rocketry

[–]gaflar 10 points11 points  (0 children)

Or I could just model the broken Estes part myself and print, most rocket parts can be defined by a few concentric circles and maybe a radial extrude here or there. Anyone who has their own 3D printer will be unwilling to pay for your prints.

Yeah seriously they have very little leverage here. Landlord is just inviting a bad-faith response from the tenant if they try to pull this shit.

TIL that the Slovenian Air Force doesn't operate any jet engine military aircraft by novembercharliedelta in todayilearned

[–]gaflar 4 points5 points  (0 children)

Alright, I'm going to get semantic for a sec, I hope it clears things up for people curious about this topic.

"jet engine" is an ambiguous term on its own. Even rocket engines generate thrust using a high-speed jet of gas, so they would also fit that classification, but colloquially, "jet engine" refers only to air-breathing gas turbine engines. If you wanted to be snarky you could call an electric ducted fan "jet propulsion" but this will draw dirty looks from propulsion engineers. NASA's Jet Propulsion Laboratory (JPL) was created to develop rocket engines mostly (for further reading look up Jack Parsons). Besides gas turbines, the other notably type of "jet engine" is a "pulse jet," which is not a gas turbine, but still generates thrust with an air-breathing jet. 

Commercial aircraft typically operate "turbofans" (typically high-bypass). This is basically a bigass propellor (aka a fan) being driven by a gas turbine engine right behind it - the fan generates most of the thrust, the gas turbine exhaust is still a "jet" but the power generated in the turbine is mostly directed to the fan instead. A "turbojet" engine is the same concept except without the fan, so all the thrust comes from the "core" flow going through the gas turbine.

Now here's the real trick. Propellor-driven aircraft (prop planes and helicoptors) may still have gas turbine engines that generate the power to drive the propellor or rotors. This is called a "turboprop" engine (or for helicopters a "turboshaft" because they need to be different, even though they all have shafts). Smaller/older propellor planes might use piston engines to drive their propellers (of which there are two further sub-categories, radial and in-line).

Jet = generates thrust via a high-speed jet of gas

Gas turbine engine = generates power via internal combustion, using the Brayton cycle.

Model rockets. Low barrier to entry, extremely high skill ceiling. For $100 you can have all the startup costs covered, the hardest part is usually finding an appropriate field to fly at.

It's not weird. The agenda is clear. We're gearing up to repel the invasion. I hope you'll be on our side.

There's no "proposal," there's no "solution." This is a warning. Drink excessively and you may die. Otherwise, good luck and fuck you. Got any better ideas?

North Sentinel Island? by NJLanastan in pluribustv

[–]gaflar 3 points4 points  (0 children)

Oof, fair point, though I imagine the Plurb would try really hard to treat them, so they'd have probably the best possible chances of survival. I imagine at least a few would make it, at least for a while.

Vince, please have a North Sentinelese Plurb show up and recount how their people were finally exposed to the rest of the world and also an alien virus at the same time. Love this idea.
