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…

Civvie Flight Control Test 1

Captain Jebediah cruises around KSC while testing out very basic software that will hopefully allow the aircraft to hold itself level in both pitch and roll without direct pilot input

Progeny Mk5 Block I Flight 2

Although the ascent did not go entirely as planned, a proper initial launch allowed the rocket to reach a staggering 493km up into space, far exceeding any and all expectations on its performance!

Progeny Mk5 Block I Flight 1

The debut of our new, more powerful Mk5 rocket was marred by weather and a launch anomaly that led to only part of the rocket leaving the launch pad, impacting the water 8km downrange with a total loss of the payload

Progeny Mk5 Flight 6

Pieced together from spare parts meant to replace any faulty/failed parts for the original 5 planned launches, a 6th base-spec Mk5 heads back into space for one final hurrah before the new Block I comes into service

Progeny Mk5 Flight 5

The final launch of the initial design for the Mk5 doesn’t reach the heights we were hoping for but it does at least set the record for being the first successful flight that was fully automated

Progeny Mk5 Flight 4

The first failure of the Mk5, however it is not immediately apparent whether the main cause of the RUD is due to the design of the rocket or conditions present on the day of the launch

Progeny Mk5 Flight 3

Additional computer control takes charge of another successful flight, though not without minor errors & also a day late launching thanks to religious protesters and strict weather constraints

Progeny Mk5 Flight 2

The Mk5 makes another successful flight almost identical in trajectory to the first but the major difference was in how the computer controlled part of the ascent, decoupling the boosters & shredding the 3rd stage fins.

Progeny Mk5 Flight 1 Analysis

Overall, yesterday’s flight was a success in that we managed to launch the Mk5 into space without any major issues. The fact that the rocket was built almost exactly the same as the previously-successful Mk4 gave us a lot of confidence that there wouldn’t be any problems with stability during the flight, but there was a little bit of worry with regard to the extra girth of the inline probe core. It was placed just above the fins to maintain stability by keeping the wider portions of the rocket closer together. While we did notice a larger precession to the rocket’s spin once the 3rd stage was flying on its own, the spin rate was high enough to keep it pointed prograde during both its coast and its boost phases. Launching at 3° from vertical was another relative unknown, although again we had previous Mk4 data to help ease concerns. The Mk4 launch with a TWR of 4 raised its nose only 1° starting from 5° so we felt safe having only 3° of pitch to play with. Turns out we cut things a bit close as even with calm winds the nose of the Mk5 lifted to 89.4° during its initial ascent from the launch base. This will severely limit launch commit criteria when it comes to wind blowing from the east. Other than these two considerations the flight performance was very similar to that of the Mk4. While there were no major issues, minor ones were uncovered during review of the flight data collected both on the ground and from the recovered payload’s telemetry data unit.
