Please do a video to illuminate what-s afoot in the DRC. They had their first peaceful transfer of power in spite of calls from a guy the west claims won the election by 60% for mass protests after a third party opposition candidate won. Then, the experts claim that the new leader is a puppet of the old one. But if that-s so, then why are the Kasai leaders and militias suddenly surrendering en masse and handing in their weapons? Is western meddling at play yet again? Is the supply of cellphone minerals safe? And what about the militant Hutus from the 94 Rwandan genocide who are massing Troop-s at Rwanda-s border in the Congo? The new leadership has sought a peacekeeping mission from the UN to deal with the impending invasion of Rwanda by the genocidaires. Wth is really going on? Oh yeah. and how-s Ebola affecting all these complex interactions? Please help!

The turbine does not produce the thrust in a jet engine. It siphons off a portion of the energy from combustion to run the fan and the compressor. The energy of the thrust is produced by the combustion of the liquid fuel. The thrust itself is a demonstration of Newton's 3rd law. For every action, there is an equal and opposite reaction. The combustion speeds up the air, which is directed rearward. The reaction is to push the plane forward.

No thrust or combustion in a vacuum. A high pressure system needs a barrier to prevent equilibrium. Ie; the -vacuum of space- cannot exist directly next to the -atmosphere- without a physical barrier.
Put another way, the metal canister of the propane tank is the physical barrier preventing the pressure of the propane inside from finding equilibrium with the atmosphere.
No rocket thrust or propulsion, in a vacuum.

I have been a big fan of crash course for a few years now - however, the level of gross inexactitudes this episodes contains regarding fundamental aerospace engineering and turbofan architecture is baffling. Things seems to be getting sloppy and loose at crash course HQ. Corrective action is needed ASAP.

Love crash course but this episode seemed to skip a hell of a lot of aerospace stuff. i'd have had space travel as a seperate episode. it also seemed very USA centric. Who calls imperial measurements english measurements? The UK adopted metric decades ago and the USA still hasnt as far as im aware.

Are rocket engines heat engines? I know that the fuel in rocket engines generates a lot of heat, but the thrust of a rocket engine comes from the expanding exhaust gasses. Things like cold gas thrusters are like simplified rocket engines, and they don't involve much heat.

What about a nuclear fusion propulsion system one within a specific heart range Propel to aircraft at least is closest to the speed of light as possible think it's feasible considering nuclear fusion is harnessing the power of the Sun

Hold up a minute here! You guys spent several episodes on environmental engineering stuff, but just 1 brief overview show on both aeronautical and astronautical engineering? That seems rather unbalanced to me.

hooray, finally we get to -military-industrial complex engineering-. We've got great branding for it here in the US though, -defense-, as if we're somehow just protecting ourselves LOL

Mars Venus and mercury then Pluto then we launch from Pluto on our first interstellar mission but my brain can-t comprehend anything at that time or think of anything past it
