SRS5 - SuperRoc Simulation, Version 5

This program calculates the optimum design of a SuperRoc model. The optimization algorithm uses a simple version of the maximum gradient method.

Latest version: 5-Jun-2021

Added "AeroTech_D9" motor, based on data published by NAR S&T
Added "AeroTech_D9X" motor, based on thrust-time curve in the AeroTech catalog
Added "AeroTech_D7" motor

Features added: 13-Apr-2021

Revised definition of Estes D12 with piston launcher ("ESTES_D12P")
Option to include approximate body tube aerodynamics per technical paper by Robert Galejs (PARAM,KALPHA)
Option to include fin interference effects per Barrowman method (PARAM,FININT)

SRS6 - SuperRoc Simulation, Version 6

This program explores a range of a SuperRoc models. The Monte Carlo method is used to assess a range of values for selected design variables such as tube length. A selected design can be further optimized using the SRS5 program.

Latest version: 5-June-2021

Added "AeroTech_D9", "AeroTech_9X", and "AeroTech_D7" motors

FlexRoc - Flexible Rocket Simulation

This is the predecessor of the SRS programs. FlexRoc analyzes a single rocket design. The output shows how the structural bending frequencies vary as a function of velocity. At high velocities, the frequency will drop towards zero, indicating that the vehicle is approaching aeroelastic divergence.

Note that FlexRoc uses a slighly different input file than the SRS5 and SRS6 programs. The required input is defined in the User's Guide, included in the .zip file.
