| Sustainer Airframe | Manufacturing Prep | Elena Romashkova 2022 |
Purpose
The purpose of the airframe is to provide structure for the rocket and enclose other components with a smooth aerodynamic surface.
Requirements
Airframe ID must be able to slip over motor OD
Must be the correct length for the rocket to have a stable margin
Must allow access to cameras and avionics controls
Must withstand axial load from the piston recovery system
Details
The airframe is a fiberglass G12 tube with 3" inner diameter and 3.120" outer diameter. It is purchased COTS from Wildman Rocketry (https://wildmanrocketry.com/collections/fiberglass-1/products/g12-3-0). It includes various holes to mount and access other structures within the rocket. On the sustainer, the airframe slips over the motor case.
Manufacturing
The fiberglass tube was purchased COTS from Wildman Rocketry. It will be cut down to a length of 60-66", and necessary holes will be added using the mill and a radial indexer, including holes to mount the piston mount, the cameras, and to access the avionics tower.
Testing
The airframe will be tested by fit checking it with other components to ensure correct alignment and fit, and may be sanded or have holes adjusted if necessary.
