- 20:08, 11 December 2012 Vincent talk contribs uploaded a new version of File:Engine thrust to weight.png (Updated with version 3 of File:Rocket_mass.c. Delta V is 8300 instead of 9000 m/s too, and overall thrust-to-weight ratio is 2.5 instead of 1.25.)
- 20:06, 11 December 2012 Vincent talk contribs uploaded a new version of File:Overall thrust to weight.png (Updated with version 3 of File:Rocket_mass.c. Delta V is 8300 instead of 9000 m/s too.)
- 20:04, 11 December 2012 Vincent talk contribs uploaded a new version of File:Final acceleration.png (Updated with version 3 of File:Rocket_mass.c. Delta V is 8300 instead of 9000 m/s too.)

- 19:57, 11 December 2012 Vincent talk contribs uploaded a new version of File:Payload 0-6k.png (Updated with version 3 of File:Rocket_mass.c. Delta V is 8300 instead of 9000 m/s too.)
- 13:26, 11 December 2012 Vincent talk contribs uploaded a new version of File:Rocket mass.c (Refining the model: better structure, more realistic fairing, adding forgotten pipes and valves, tanks alignment on outer shell, composite skirts for non-structural or soft tanks.)
- 00:26, 11 December 2012 Vincent talk contribs uploaded File:Rocket model.png (Rocket model illustration for the computed rocket model: File:Rocket_mass.c)
- 03:10, 27 November 2012 Vincent talk contribs uploaded File:Rocket ignition.png (Graph of the rocket trajectory for first moments after release, assuming ignition at the time of the release, a thrust vector with 45 deg pitch, and an overall thrust-to-weight ratio of 2. No atmosphere considered whatsoever.)
- 02:01, 24 November 2012 Vincent talk contribs uploaded File:Heat transfer to rocket tank.c (Program calculating the heat transferred to a cryogenic tank (typically LOX) for balloon- or air-to-orbit vehicles. Two heat transfer approximations are done. * when the vehicle is waiting on the ground after tank filling and before it lifts-off from the )
- 02:59, 17 November 2012 Vincent talk contribs uploaded File:ISA atmospheric model.c (C Implementation of the international standard atmosphere ([https://en.wikipedia.org/wiki/International_Standard_Atmosphere ISA]) model. This is a port of http://www.digitaldutch.com/atmoscalc/ .)

- 01:33, 9 November 2012 Vincent talk contribs uploaded File:Rocket mass tanks v1-2.png (tank model for rocket mass versions 1 and 2)
- 03:51, 7 November 2012 Vincent talk contribs uploaded a new version of File:Rocket mass.c (composite skirts, propellant venting and tank insulation (given data, not computed), mass ratio computed from delta V and Isp.)
- 02:47, 2 November 2012 Vincent talk contribs uploaded File:Rocket mass.c (Program that iterates to compute an SSTO rocket's dry and wet mass (and other parameters). Compile with gcc -O2 -Wall rocket_mass.c -o rocket_mass -lm for normal use, and add -DMAKE_GRAPH after gcc on the command line if you want to create graph data as )
- 02:15, 2 November 2012 Vincent talk contribs uploaded File:Payload 0-6k.png (Graph representing rocket dry and wet mass as function of the payload mass (or any other fixed mass subsystem), ranging from 0 to 6 kg payload.)
