Tag Archive: Progeny Mk6 Block I Flight 4

The final launch in our latest campaign has been to space and back. This ends our initial exploration of the hazardous radiation zone discovered above the planet, a report on which will be published separately after more data collection and analysis from future Progeny launches. We’ll cover that at the end as usual, for now let’s take a look at this recent flight in detail.

The Flight

Once again the only major change to the ascent profile of the rocket was to launch even further to the south, lifting off from the launch base at precisely 09:02:00.06 local time to head 150° SSE after a delay due to low cloud cover. 67.2kN of thrust from the lower 0.625m booster pushed the rocket at 4Gs and climbed to 68.9kN before beginning to taper off after just 3 seconds to ensure the rocket did not speed through MaxQ too fast, topping out with a dynamic pressure of 77.104kPa passing through 5km traveling at 550m/s at L+18s. Staging occurred at L+35s, 14.9km ASL, after the lower booster expired and was pushed away by the decoupler, its fins shredding via det-cord 1 second later to spoil its lift and send it crashing downrange into the Kerblantic .

Coasting for 7.62 seconds before the nose fell 1.5°, the AFCS kicked off the second stage booster at 18.5km to boost at 14.7kN with a TWR of 3.1. Trajectory remained stable throughout the burn until the booster expired at L+54s, when the stage was dumped and the third booster ignited one second later at full thrust to continue the push for space.
