Acceleration to minimum scramjet speed (M3.0?).Initial climb (airfield elevation to 30-35k ft).
Profile-wise, the flight can be divided as follows: Might be stating the obvious, but it helps me with my ad-hoc analysis. I haven’t ran the numbers yet, but there are a few things I’ll type up. Some of you might recall how in KSP the “space” music starts to play when you escape the atmosphere (70k altitude, from memory)…I was half expecting that music to start playing when I reached 275k ft and chuckled at myself It’s quite fun - reminds me a lot of doing spaceplane things in Kerbal Space Program! About as realistic, also - but who cares! It’s pretty neat to get to do this in the beautiful MSFS world. It’s hard to get a good session in at the moment, but I got to run a few ascent profiles today. Not that we would do that, but it’s good to know.Ī more useful statistic is that 90% RPM maintains a benign 400 kts at the kind of altitudes you may find yourself if looking for an airport after a speed run, and results in a 14 x 1000 PPH fuel flow, i.e.
Darkstar one problems full#
So somewhere between 7 and 12 minutes of full burner at low altitude before flameout. The turbine fuel flow varies quite a bit, but full afterburner at low altitude tops out somewhere around 120-150 x 1000 PPH, less on lower speeds (perhaps 80-100 PPH). It appears that the fuel flow gauge shows turbine FF when the scramjets are off and scramjet FF when the scramjets are on and the turbines off.
The middle tanks (marked red below) are the scramjet tanks and the outer tanks (marked blue) are the conventional jet fuel tanks. The scramjet tanks total 21,815 lbs of fuel.Īs far as I can tell, the only fuel gauge in the Darkstar is the visualization of the aircraft with the tanks showing in green. The four conventional tanks total 17,849 lbs of fuel.
