Modifying Simulation for Challenge Goals n High powered rocket kits are not typically designed to accommodate ‘challenge’ payloads n There will need to be modification made to your rocket kit (both in the simulation design and physically) to incorporate the challenge payload n In addition, most kit models do not contain all necessary components which should be added to the model, as to best represent the physical rocket once built n During procurement, kit components can usually be exchanged by the vendor if requested (motor mount diameter, tube length, etc. ) 41 9/24/2021 Rock.

Recap n Vehicle Level Mass Override is BAD n Component Level Mass Override is OK (use sparingly) n Vehicle Level Cd Override is BAD n Dual Deployment (your competition rocket) is more detailed and challenging than Single Deployment (your certification rocket) 64 9/24/2021 Rock. Sim Webinar

Simulation Process – Design Steps n Estimate size of challenge solution payload (weight and volume) n Select an existing kit that will accommodate the payload (volume) n Open or import kit model into Rock. Sim n Ensure all components of the kit are accounted for in the model n Select a motor such that rocket achieves technical criteria n Iterate 65 9/24/2021 Rock. Sim Webinar

Simulation Tips n Try to incorporate all components in your simulations as early as possible (we see they affect performance) n Update your simulations weekly or bi-weekly (as your team confirms component selections) n Your final kit should be selected before CDR phase n Your final motor selection is due at the start of CDR n n 66 All component selections should be made by this point There should be little to no design changes after this point 9/24/2021 Rock.
