    KSP Weekly: The Moon Race

    So do I. But @SQUAD seems to think that no news in the past 2.5 months is keeping us informed, so they've earned it.

    KSP Weekly: The Moon Race

    Since we're supposed to be reading between the lines for console news, does an update every 3 months mean we can expect an update in 2 weeks?

    vacuum engine development and testing.

    https://en.m.wikipedia.org/wiki/Rocket_Engine_Test_Facility Vacuum test facilities exist, just maybe not for something the size of a raptor. They could test their scale model, and validate the flight worthy engine with a computer model.
  4. While both water and air are fluids, water is significantly denser. Even if the aircraft is facing the tsunami, fast moving water could easily exceed the dynamic pressure the aircraft is designed for. Best bet is getting away from windows and off the ground floor.

    KSP Weekly: Thrusting into the future

    @SQUAD Since you haven't mentioned console development since the second patch was released, I can only assume there is none occurring. As much as I like the game, seeing all these improvements for PC and knowing my Xbox will be stuck on v1. 2x forever makes me not want to play anymore.

    2mm hole in ISS

    A common repair on aircraft, assuming the mis-drilled hole poses no structural danger, would be to plug the hole with a rivet and sealant. If there is a structural issue, some sort of doubler would be applied. Mis-drilled holes happen, and the worst thing a manufacturer can do is punish the worker who made the mistake. That leads to things like this at best.

    KSP Weekly: The Solar Visit

    @SQUAD Is any of this, including the expansion, coming to consoles?

    KSP Weekly: Ultima Thule

    Since my aging laptop decided it no longer needed a screen, I've been playing on Xbox. Seeing all the improvements pc is getting is nice, but consoles don't have making history, or even a clear future. It's really hard to justify a new machine for one game, even if I have nearly a thousand hours in it, when something I already have will play ksp. Are consoles going to get making history and these updates? Not looking for a date or schedule, only a yes/no answer.

    Jet engines and compressors

    Jet engines and compressors

    Because the process of compressing air slows the air down. The compression/deceleration process starts at the intake on all jet engines, slowing it to less than 0.3 Mach before it reaches the compressor. This is because below 0.3 Mach, air can't be aerodynamically compressed. From there, multiple compressor stages mechanically work the air. These can be numerous axial rotor/stator stages, or on some engines, a few axial stages and a large centrifugal stage before the burners. The idea is the same, something speeds air up and forces it into something stationary to increase pressure. On a ramjet, the intake air is fast enough that aerodynamic compression is enough to operate the engine. No moving parts needed.

    KSP Challenge: Impact the Mun!

    At 15:02, I think I'm close to the max of what an xbox can accomplish. Didn't bother to look at the total part count, but those vectors sound like an evil horn.
  12. The fuselage is one awkward airfoil. On conventional aircraft, the fuselage is usually assumed to produce as much lift as the wing area it covers. Assume the chord is the length of the craft, and the area is what you see in your top down view. The easiest way to calculate area on that is to break it down into simpler shapes.

    GPS navigator on a space station

    It doesn't even need to be in space. Next time you fly on an airliner, have a navigation app open. Your phone will drop GPS shortly into the takeoff roll because it senses excessive acceleration. For entertainment, if you get the chance to fly on something smaller and slower like a skyhawk, open a navigation app and watch it try to figure out where you are.

    For Questions That Don't Merit Their Own Thread

    I might be a savvy engineer, so I'll take a crack at this. Engines work by using a heat source to cause a working fluid to expand as a means of transferring energy from fuel into mechanical energy. The problem is most working fluids don't hold much thermal energy at useful temperatures, limiting the energy output and efficiency of the engine. The solutions are either increasing the operating temperature or increasing the mass of the working fluid. Increasing operating temperature usually isn't an option, at least not by enough to make a difference, due to material properties and cooling. Increasing the size of the engine can dramatically increase energy output by increasing the volume of working fluid, but at the expense of efficiency due to difficulty heating all the working fluid. Compressing the working fluid increases the mass being heated while keeping the volume being heated reasonable, allowing more chemical energy to be captured as heat, resulting in increased energy output and efficiency of the engine.
  15. The problem is transferring gasses to and from your blood relies entirely on pressure. If the pressure of oxygen in the air is less than the pressure of oxygen in your blood, then oxygen moves from your blood to the air in your lungs. Above about 35,000 ft, the ambient pressure is low enough, that the time of useful consciousness becomes constant. This is because there isn't enough air pressure to keep enough oxygen in your blood for you to remain conscious. It then becomes a race of you using oxygen vs. oxygen and other gasses escaping in your lungs. Holding your breath will not stop this because breathing also relies on relative pressure.
