This gives me an opportunity to ask a question that's bothered me for awhile. Does anyone know the physics reason for this? I always wondered why max deceleration came after max heating during reentry, for example. Why would a small increase in air pressure lead to higher and higher rates of...

Absolutely. The concept is a lot simpler than I thought it would be. Thanks a lot for the description! I guess where I got confused before was that I thought the sling at point B on your images would reverse your heliocentric orbit, when it would in fact only lower its speed relative to the...

Thanks for the reply. I'm glad you suggest that it's at least theoretically possible. The Mars aerodip in particular is something that I never considered. I do have a question about 'climbing down the ladder' as you put it, and maybe you or others could give me some advice: When you sling...

Like many of you, I had a successful voyager style flight to Neptune many months ago. I did this in an XR5 and had enough fuel to barely return to the inner planets. The problem, of course, was that the return orbit had extremely large speeds as it approached the periapsis, which I had no...

Thanks. It just occurred to me that I should have given my own numbers when asking that question :facepalm: I barely get up to mach 0.55 with full thrust by the time I reach 10km altitude. I think the problem is that I turn the afterburners off too quickly after take-off and kind of semi-stall...

What's a good velocity/rate of climb/thrust for the initial subsonic ascent? I waste a lot of fuel and struggle the most at this stage of the flight... Great plane by the way.

I planned a round trip from Earth to Neptune in an XR-5 a few months ago. It was also my first trip to Neptune, so I had no idea that I would have to aerobrake through Earth at at least 40 km/s. Apparently falling for 15 years gives you a lot of speed! I spent the next half hour trying to...

Hello! I am new to the forum and started Orbiter a bit over a week ago. I made my first round interplanetary trip yesterday, flying the X5 (it's a heavy mother). I'm amazed by Orbiter's detail and scale, but also its wide range of addons and large community. Thanks for having me as a member...
