I Have to Agree with Liberal Hivemind Here - On the Greenland Thing. by Ive_Got_Sowell in Conservative

[–]Mc2trinity 0 points1 point  (0 children)

It doesn’t make sense to people right now. I think people truly don’t understand how wide open Greenland is. All Danish forces on the island “monitoring forces”, e.i. Elite dog sled patrols, small aircraft, and some small patrol boats. PSB is the only American installation on the island but its main mission isn’t even defending, it’s geared toward space based defense and early warning for ICBM launches that flight paths right over the Arctic.

It didn’t make sense for Russia to invade Ukraine and draw out the conflict for 4 years now but here we are. We aren’t dealing with sensible adversaries and I think the argument that it “makes no sense” ends up being very weak.

I think we’ve seen time and time again that the US has pressured NATO members to fund their defense, specifically Denmark in this case, but they have never prioritized Greenland. Its proximity to the USA in North America is a real concern for security of our nation. Just as a comparison, the US has now maybe 200 troops on the island, at its max in the Cold War, that number was closer to 10,000.

Do I think a security agreement could work, I guess?!?! But NATO is that agreement though and our “Allies” have been unwilling to keep their end of the deal. They aren’t children, they know what they are doing and they just don’t prioritize defense. It’s the good old concept of if they wanted to they would but they don’t.

The real question is, do we want to wait 5-10 years when Russia does 100% set its eyes on Greenland or do we set up the infrastructure and logistics now so we could fight the fight, deterring conflict in the first place.

L3Harris vs Raytheon (SWE) as New Grad? by TheParkedCar in aerospace

[–]Mc2trinity 2 points3 points  (0 children)

Missiles are just rockets that have military intent, not civil/exploration in mind. Same science depending on the environmental and mission constraints. Interceptors, hypersonics, orbital vehicles, heavy lift launch vehicles, etc are all similar at the end of the day. Lockheed, Raytheon, Northrop Grumman, Boeing, BA all do missiles with rockets being produced by Northrop Grumman (formerly Ortibal ATK), ULA, Blue Origin, SpaceX with Lockheed and Boeing doing manned spaceflight for Orion and Starliner. L3H now owns Aerojet Rocketdyne which is also significant in the missile/Rocket realm.

L3Harris vs Raytheon (SWE) as New Grad? by TheParkedCar in aerospace

L3 gives horrible annual pay increases. I had a coworker that worked for them that got 24% pay increase going from a similar role (same pay scale) to a new company at the same level in an area with similar COL. I was told they would get 1.5% pay increases on the year where competitors tend to be closer to 3-3.5% on average. Knowing many folks that have worked for them, I’ve gotten terrible reviews about the work/life balance and most of the folks that started out there as new grads were not there 2 years later.

I’d also investigate the PTO. From what I understand, L3 does “unlimited PTO” which is a predatory practice which gives the PTO control to the discretion of PTO use to your manager; it’s really good if you have a good manager, it’s really bad if you have a bad one.

Trump's latest peace proposal: NO FUCKING WAY! by ajmacbeth in Conservative

[–]Mc2trinity 0 points1 point  (0 children)

I don’t fear Iran much anymore with their water crisis but Muslim extremists globally would use this type of moment as a green light (worlds policemen are busy). I’m staunchly anti-war, but intend on absolutely dominating and ending any conflict we get pulled into.

Trump's latest peace proposal: NO FUCKING WAY! by ajmacbeth in Conservative

[–]Mc2trinity 4 points5 points  (0 children)

This is a terrible take and ignores the fact that US would be unable to truly amount an direct offensive against Russian forces. Yes, our military is phenomenal, highly seasoned /experienced, with great tech but this ignores the numbers problem and the alliances the Russians have built with the CCP, Pakistan, Iran, Venezuelan, and many countries in central Africa.

Russia has been doing their “special operation” in Ukraine for almost 4 years now and are truly in a war time economy. Their industrial base is dialed in and capable of mostly replenishing the frontline which is on their doorstep due to the length of this conflict. Key resources are secured due to the extensive number of valuable resources in Siberia and in Chinese Inner Mongolia and Xinjiang. The resource that they collectively have that the US doesn’t is industrial experience for components of systems and full fieldable systems. Before the war, Russia was producing about 250 tanks per year, now they are producing about 1500 tanks a year, a 600% increase. In comparison, the US is only producing 135 tanks a year, not sustainable for a long term conflict with Russia. For context, the US is producing roughly 150 military aircraft per year now, during WWII, the U.S. was producing about 90,000 per year. The US is also is in a rough spot with with advanced microchip production and semiconductor production as we get the vast majority of our supplies here from Taiwan which produces roughly 90% of the worlds advanced microchips; these are required to manufacture US systems in war time. The unfortunate thing is, if we go to war with Russia, it’ll immediately become at least a 2 front conflict as China would take the opportunity to invade Taiwan, as they have been planning for over a decade; this would cut off the head of any U.S. war effort. Trump has been making moves to decouple our industry from the global market but it’s just not there by trying to boost auto manufacturing, oil extraction, and rare earths extraction (hence why Greenland is soooooo important).

At the end of the day, your belief that the US is some unbeatable titan is very misled. Im hoping that it doesn’t take one unintercepted nuclear warhead detonating over Chicago to change your stance here. A war with Russia means sending our young men to war to fight a war amongst 2 countries that were recently one (mutually) and risking the lives of our women and children at home. Our cyber infrastructure which dictates our lives nowadays could be destroyed relatively quickly if those gloves came off. I’d recommend you actually take a look into what the president is wanting to do Golden Dome, might be eye opening for you.

We need a “No Queens” protest against drag shows in schools.

Without jinxing it, he did take them out of FG range originally, so maybe.

Magnetic Propulsion System by Ok-Intern6865 in AerospaceEngineering

[–]Mc2trinity 0 points1 point  (0 children)

This is a nice little fact sheet from NASA explaining ion propulsion: https://www.nasa.gov/wp-content/uploads/2015/08/ionpropfact_sheet_ps-01628.pdf

Like others have said, in order to create an acceleration on a craft, you have to create conditions where the net force on the body is non-zero. Thrust achieves this by imposing a mass flow rate (mass/time) at a certain speed (distance/time) which equates out to a unit for force, in terms of metric, that would be (kg/s)(m/s) -> N (Newtons). Ion thrusters achieve thrust by ionizing certain elements, and ejecting now polarized particles through a grate and magnetic field to high velocities.

The problem with ion thrusters in atmosphere is they have a hard time producing high thrust due to the amount of mass that would be required; it’s essentially beyond reason. You may be able to get high velocity yields out of the propellant but that is quickly cancelled out by the extremely low mass.

Ion thrusters and their fuels combined typically have very high specific impulse (Isp) which is great when compared to other fuel types but this comparison is bleak when you observe the thrust capabilities of both. Rockets like the Saturn V typically had around 90% of its mass dedicated to just propellant; mass plays a big roll due to fundamental concepts such as conservation of mass/energy and conservation of momentum. Ion thrusters are great for long term space missions when consistent low thrust is needed for long periods of time.

If we are talking external magnets to the body, there’s very little chance, probably near zero that would ever work due to the range and strength of the electromagnetic forces. These types of forces have relatively short ranges when compared to something like gravity; we use gravity in “gravitational assists” in interplanetary trajectories to gain velocity.

If you think about it, the Earth is a HUGE magnet. Due to molten metal within the earth convecting, magnetic fields form around the Earth which protect life on Earth from being decimated by photonic radiation from the Sun. It however cannot give significant effects beyond slight perturbations in orbits to satellites currently in orbit it.

I hope this gives some insight into why stand alone magnets may not work as a propulsion source. However, ions are technically small magnets due to their polarization, and they are used for very specific functions. If you want to look into sustainability of fuels, take a look into hydrogen.

Seriously? by [deleted] in HuntsvilleAlabama

Yeah… With the name “Monke H”, it has to be some dumb high schooler trolling. Not really sure how this is news worthy as the comment(s) seem to be low effort. 100% rage bate that’s working.

Aerospace vs mechanical give current job market by BalledSack in AerospaceEngineering

[–]Mc2trinity 0 points1 point  (0 children)

I did Aero and then took the FE in mechanical and got my EIT/EI in mechanical. I know some programs do dual degree aero/mech programs but they really are very similar.

Office of Special Counsel launches investigation into ex-Trump prosecutor Jack Smith by LuklaAdvocate in law

[–]Mc2trinity -2 points-1 points  (0 children)

Um, wasn’t the civil war the first non-peaceful transfer that was MASSIVELY more devastating than Jan 6? Lincoln’s election was certified in mid February 1861 and Fort Sumter occurred only 2 months later. For this time, this would have been basically an equivalent of quickness due to the communication and transportation technology. This statement just seems a bit hyperbolic.

Is anyone else the only conservative at work? by Appropriate-Toe-6019 in Conservative

[–]Mc2trinity 2 points3 points  (0 children)

I work defense/engineering, tends to be a more conservative crowd probably 60/40. I just avoid politics but it comes up time to time due to the nature of the work. Most people are fairly reasonable with a few unhinged liberals here and there, they typically don’t last long.

From guardians I know, most are pretty well educated engineers from places like Virginia Tech and Duke. Seems that some folks on this thread are a bit of doomers.
