Progeny Mk6 Block I Flight 1

The debut flight of the Mk6 Block I goes off without a hitch, setting new records for speed and height over Kerbin but the extra velocity has made recovery even more difficult despite extra preparations

Progeny Mk5 Block I Flight 4 Analysis

Engineers on the Progenitor team have spent the past week carefully analyzing telemetry data not only for the most recent fourth flight of the Mk5 Block I but as well for the entire series of Block I flights. The second flight of the Block I especially was of interest given that it reached nearly the same height and followed a much different trajectory. As usual, we will take a look at the details of the fourth flight first and then move on to the comparative analysis that leads to decisions made for the future of the Progeny rockets.

The Flight

After the numerous delays, the rocket lifted off from the launch pad at precisely 10:00:00.03 local time, soaring up into mostly-clear skies on its first stage 0.625m booster pumping out an initial thrust of 67.2kN for a TWR of 4.02. The nose pitched up only 1.4° before beginning to fall as the rocket tracked eastward away from the Kerbal Space Center. The first stage booster’s thrust profile began to reduce thrust 5 seconds after ignition, relieving stress on the rocket as it continued to climb and passed through a maximum dynamic pressure (MaxQ) of 77.371kPa at L+17.79 seconds. The booster thrust tailed off to just 17.3kN by the time propellant ran out at L+33.67 seconds at an altitude of 14.4km – it was decoupled cleanly one second later and the fins were shredded properly one second after that while the rest of the rocket coasted into the upper atmosphere.

Progeny Mk5 Block I Flight 4

The first flight of 2018 takes the Progeny to new heights as we test out what we felt were our best ascent procedures to date, shattering several records along the way and increasing our knowledge of space flight

Progeny Mk5 Block I Flight 3 Analysis

Progenitor team members have spent the last few days reviewing telemetry data from the third launch of the Mk5 Block I in order to determine the overall performance of the rocket and what happened to cause two anomalies that occurred during the ascent into space. Both have been tracked down to their root cause and we will cover them after review of the flight.

The Flight

No issues preceded the launch, with perfect weather deciding to show up for launch day although we had plans in place to push into the weekend if necessary to get the rocket launched before the end of the operational year. The lower 0.625m solid rocket booser lit off at 12:30:00.03 local time to push the rocket away from the launch base at 4Gs with 146.142kN of thrust to establish the rocket in its initial climb and not allow lift at the nose to flip it vertical or over backwards. Launching from 85° It stood up to 86.8° before beginning to pitch back over towards the east and away from KSC. After 5 seconds the new lower stage began to reduce its base-level thrust output although given the rocket was climbing into decreasing air pressure the overall thrust continued to increase. 10 seconds after lift off it had reached Mach 1 and 8 seconds later dynamic pressure began to fall as it passed through a Max Q of 78.373kPa, within our planned range of 60-80kPa. It burned out after 33.71s with a thrust of 172.596kN, pushing the rocket to a velocity of 653.520m/s at an altitude of 14.009km.

Progeny Mk5 Block I Flight 3

The final flight of 2017 saw a triumphant return to space with a redesigned Block I solving many of the issues that plagued the previous flight, although it also introduced some new ones. The quest continues…

Progeny Mk5 Block I Booster Test

Looking for more efficiency and less brute force for our initial ascent, a newly-designed core will produce high thrust for the first 5 seconds then taper off – at least it should. We static fire it to see if it performs as designed
