  1. OpenRocket simulation drifts far when wind is 0 mph?

    I set the average windspeed to 0 mph. The simulation has the apogee at 4531 ft where the ejection charge fires. The ascent is near vertical. I delay chute decent deployment until 500 ft (Jolly Logic). The simulation has the rocket landing 6265 ft away from the launch site in 97 seconds after...

    It's been 6 years since V15.0.3 was released. I see lots of emails on the lists about issues and I have a copy of a beta version 17.11-rc2.1 from 2018. At the minimum there are lots of AeroTech motors that have been approved that aren't in the database. It would be great to have an updated...

  8. OpenRocket: How to ignore stability issues?

    I'm simming a short/stubby rocket with lots of base drag. To get an idea of stability, I add a massless transition cone at the tail as recommended elsewhere, and I get a stable rocket. To sim the altitude, I remove the transition. However now OpenRocket is telling me that the rocket...

    I needed to sim some motors, and I couldn't find the 4' Magg file anywhere. This is down-scaled from the widely-available 5.5' Mini Magg.Most components from the DB. Some measurements are from my own rocket. The rest are just a guess.Posted here cause someone else might want this someday.

    When we do the simulation, it gives warning that the parachute is opened at high speed. However, the parachute opens at the apogee point where the velocity of the rocket is 0 m / s. When we examine the graph, we see that the velocity at the opening point of the parachute is -0.5 m / s. However...

See full list on spacha.github.io.

Here you will find manufacturer specs, certified performance data and other info on commercial model rocket motors and high-power rocket motors. Most importantly, you can download thrust curves for use with rocket flight simulators(RockSim and OpenRocket among others).

  • But, openrocket does not work with java 11 (or anything 9 and above). So I believe it would be best to change the dependency to java-environment=8 so that users would have java 8 installed and they can change java versions via archlinux-java.

  • Level 3 Certified 9 months ago. Drop the.eng file into C: Users username AppData Roaming OpenRocket ThrustCurves. That's Openrocket's default location for thrust curves, so there's no need to add the motor to the path in settings. Note that sometimes Burnsims.eng files aren't quite correct, so it's worth opening it.
