Did you guys have reasonable success with OpenRocket or RASAero in predicting this performance?
I only simmed the 1040 in RS and OR, although I have simmed this rocket in RASAero but that was for the Loki K350 Moon burner and I don't recall the sim numbers but they were comparable to OR. We were having discussions the night before the launch about which motor to burn, the L1040 or L1400, and I ended up launching the 1040 just because I wanted to see which sim was closer. OR was pretty accurate for the L1040 which was +4% on the prediction vs. realized, which is great but RS was -20% off.
Got Mach 2.1 and 18.4 k on a Loki L1400 in a Mongoose 54...melted the decals off. Love that rocket.
For comparison to Cl(VII) Mongoose. I have also launched this rocket on the Loki L1400 White. My predicted numbers were 18000 @ M1.78 and she realized 17,000 @ M1.75. However the rocket was launched on a relatively windy day @ roughly 5° into the wind and when you follow the GPS track and straighten out the arc of the flight path it would have made 18,000 easily...so that sim was very accurate, +-2%
If you're a Loki fan I have flown this rocket on all 4 reloads for the Loki 54-2800 hardware. Those being the K350 Moon burner once, K830 Spitfire twice, L1040 Red once and the L1400 White once. I would have to say the most interesting is the Moon burner but it needs a dead calm day. My favourite overall is the L1040 Red because it looks like a SAM. However the crowd pleaser seems to be the K830 Spitfire, which tends to get everyone's attention on the flight-line, whether they were planning on paying attention or not.
