Experimental

A user's motor version is also available.

ALL NEW MOTOR THRUST PROFILES

as of 26 April, 2004
Updated again with new Ellis Mountain motors and Revisied Loki Data on 13 December, 2004

Read about it at http://webalt.markworld.com/webalt.html
The old profiles are still available by using http://webalt.markworld.com/multistage1.html

This page drives a rocket simulation program which will project the peak altitude and other flight profile information about a multi-stage model rocket. A single stage version is available at http://webalt.markworld.com/webalt.html.
First read the disclaimer.
Then fill in the requested information about your rocket.
  • For each stage, you can select up to 3 motor sizes and specify a quantity of each size. Leave the quantity blank for unused motor sizes or stages.
  • Masses specify the launch mass of each stage and everything that will be lost when it is ejected. The sum of the individual stage masses entered should equal the launch mass of the entire vehicle including motors and propellants.
  • Staging delays are specified in seconds from stage start. A stage ejects and the next stage ignites after this delay.
  • Cd for each stage is the entire vehicle including that stage.
When all appropriate data is filled in, click the LAUNCH button to start the simulation and receive the results.
