Oh well, there actually is more info about the vehicle outside XCOR’s press release (why didn’t they put that there?). Here, at Clark Lindsey’s Hobbyspace. Seems my speculations were a bit off-base, the dry mass was fine but the mass ratio is a lot bigger, about 3. I noticed after posting from the flight profile that the burn is quite long, 3 minutes, giving more gravity losses… So, with all this taken into account, a big part of the speculation below is wrong.

Well, I didn’t expect this, I thought XCOR had gotten an outside contract when they announced early this week they’d announce something on wednesday.

2 people to 62 km. All-rocket propulsion, horizontal takeoff, glide landing.

Interesting though, I had talked about this to a friend in February, how such vehicle would make perfect sense as a start: liquid engine with pumps to ensure very low operations cost: essentially just refuel and go again – and small size (one passenger) to enable low capital cost and easy improvability.

I was already going through Lynx in my head in the day, itching to reverse engineer the engine specs, so here goes. 🙂
