I am working on a college project which is based upon a experimental sounding rocket and it would be really helpful if the community could refer me good softwares to simulate trajectories of a rocket.
The principal software that I found (and free) is the "Comprehensive General-Purpose Simulation of Attitude and Trajectory Dynamics and Control of Multiple Spacecraft Composed of Multiple Rigid or Flexible Bodies" from the NASA Technology Tranfer program. More alternatives in the same catalog:
OpenRocket is free based on JAVA runtime. I have personally used this. So long so good. http://openrocket.info/
RockSim is a paid version.
RAS Aero is an other option.
I believe you can specify a custom rocket and flight plan in flightclub.io
The examples below give you some idea of how it works. The big image is the first launch of the Falcon Heavy, you can see the two side boosters land on the left and the center booster over the horizon on the right.
Here are some example images found on the following pages. The developer of the site can be reached through the site and is also an occasional visiter here: @DeclanMurphy
