Interesting take on the basics
Detach a small capsule with the humans that goes directly to the surface (with only days of life support) and leave the untended craft to do multi-pass aerobraking Continue reading
This is a bit different from the NK-33 done previously, but it’s still a full flow oxidizer rich staged combustion lox-kerosene engine. It has no gears and no flexible shaft coupling between the pumps like the NK-33, making it a … Continue reading
But is not a real RLV program. It’s just a narrow test for one technology. Hence I think naming it Reusable Booster System Pathfinder is misleading. Overspecification They overspecify the problem by requiring a glide landing. Why is it superior … Continue reading
Karoliina has some thoughts on plane design, looking at High Altitude Long Endurance (HALE) UAV:s as inspiration for high L/D craft, to ultimately cruise at fast speed with little power. I disagree somewhat, and I’m sketching out why, below. Probably … Continue reading
Altitude was 2222 m. Apparently the backup timer shot the drag chute out while the rocket was still ascending. The team said they have video and will upload it later, if asked nicely enough. 🙂 Meanwhile, some launch photos. You … Continue reading
Robert Grumbine examines them in many of his recent posts. This might be good for engineers and physicists from other fields trying to get the basics.
