Man, I am jealous. I definitely need to get out and exercise more. I remember not long ago when I was in high school, I ran the 5K in 17:30 minutes. Came out to something like 5:36 per mile pace.
Hahaha, we wish!
That is the inversion temperature. That is the temperature at which you can begin to cool H2 via throttling. If you try to cool H2 above 204K via throttling, you actually heat it up!
To liquefy hydrogen or helium, you have to intially cool the gas. You cannot use a throttling process (where you isothermally compress the gas into a liquid state, and then let it cool by decompression) for hydrogen and helium at room temperature.
The attractive interactions for these gases are...
I've piloted the Diamond DA-40 and I can tell you she is very enjoyable to fly. Light wing loading makes it feel like a glider (Diamond did make gliders before manufacturing airplanes).
The motivation and aptitude to learn! And heart!
Which I bet you have! I have been doing this for seven years and I am still learning new things.:tiphat:
I believe I have a simplified solution for this system, assuming this aircraft is using a tricycle landing gear. This was a nice little mechanics problem. RisingFury did a good job on this problem and Miner1. This solution should be easy to follow.
Simplifying this solution relies on...
I see that this was the route I ended up doing. I will definitely skim through that tutorial. I remember using IMFD v. 4.2 for recreating the Grand Tour of the outer planets, but that was a distant memory of 6 years ago.
I really like IMFD. It seems like I have a more situation awareness of my...
Having traveled to the moon countless times using TransX, I was thinking of getting my feet wet with IMFD.

Using the latest version, I cannot follow this tutorial because the course-intercept program is always...
