    Orbiter 2016

    The oldest version on Orbithangar is 010503 which means that Orbiter is a Taurus. There you go. :cheers: ---------- Post added at 11:38 AM ---------- Previous post was at 11:31 AM ---------- I am going to have to say :hailprobe: for at least two weeks for that. :facepalm:

    Question What is an electrical bus exactly?

    In an electrical diagram the order is irrelevant. In a wiring diagram the actual position can be relevant depending on the type of equipment/cables used. I'm sorry if I'm adding to the confusion, but I've worked so long with stuff like this that it's intuitive to me, and I find it hard to...

    Question What is an electrical bus exactly?

    That would make the D cell explode. Lead Car batteries are designed to deliver relatively high current. If you want to tie power supplies you need then to have identical nominal voltage, and a similar reaction curve. You certainly wouldn't design a bus with that option.

    Question What is an electrical bus exactly?

    In reality there is no power supply with no resistance. When calculating current a battery cell is represented by a constant voltage and an "inner resistor" to calculate the voltage of the battery terminals. As the cell is discharged the inner resistor increases, lowering the voltage on the...

    Question What is an electrical bus exactly?

    I think you are confusing electrical diagrams, wiring diagrams and single-line diagrams. Buses are generally drawn in single-line, but that doesn't say anything about the wiring. It depicts an overview of the connected parts. A bus isn't parallel unless you tie two buses together. (like during...

    Question What is an electrical bus exactly?

    Only if the "consumer" has a regulated power output. It's much more likely that the consumer has a specific impedance (Z), so the power consumption will fall with the falling voltage.

    Question What is an electrical bus exactly?

    Of course. Every electrician here has done that during training. In reality square copper bars aren't used "below" distribution switch boards. Most switch boards use copper profiles specifically to save on material.

    Question What is an electrical bus exactly?

    Actually it can, but only for a very short time. Circuit breakers have to be quick to protect the system. BTW a million amps is a million amps no matter what the voltage. Fun fact: One of the reason for the bulky copper bars is to withstand the magnetic forces during a short circuit.

    Question What is an electrical bus exactly?

    A diagram shows electrical connection, not physical form (although they can be similar in shape). The lines on the diagram are used to provide a clear picture at a glance. The actual bus could be an isolated bolt with a stack of terminal connectors. (not recommended!!!)

    Question What is an electrical bus exactly?

    A bus is just a 'point' on the electrical diagram that can be isolated. The physical object can be anything from this: To this:

    Realistic Space Flight Simulator

    I usually call it a "game" if the goal(s) is set by the program, and a "simulator" if the goal is set by the user. There are some that fall in the gray area, but I'm not really bothered by the label. You could argue that anything done for recreation is a game, but that would make chess a...

    Internet Video Thread

    I really liked this presentation. It's not aimed at space enthusiast like orbiterforum members, but I think it's important to remember that there was a time before we knew what reentry was all about. PS: And we can never have enough footage of the Commander's HUD during TAEM. :)

    This reminds me of a comment someone posted on a flight sim forum about MSFS X. It went something like this: "The elephants are moving! OMG!!!! MSFS X is the most realistic flight sim EVER!!!!!"

    You're an Ewok? PS: Sometimes this forum feels like a room full of Dr. Sheldon Coopers. The scary part is that it makes me feel right at home. :thumbup:
