The airframe team is responsible for design, construction, and maintenance of the physical rocket itself. We work with the body (tube, fins, nose cone, etc.) of the rocket as well as the recovery system (parachutes), electronics mounting and other complex internal systems. We have frequent discussions about the future of the rocket and how it may be built. Once we come up with solid ideas we polish the design and apply principals of mechanical engineering and occasional computer modeling to ensure a working final product. We then construct and test our hardware before assembling the final rocket.
Meetings: The airframe team meets weekly with the main group. See the PSAS schedule page for upcoming meetings.
Airframe Team Mailing list: We have a mailing list for active PSAS airframe team members.
New: build a model of LV2.3
Since PSAS has launched more than one rocket we had to start naming them. You will see us refer to things like "LV2.3" which stands for "Launch Vehicle 2, revision 3." Some past rockets include:
LV2.2 was in many ways a huge success. It was a LV2 class rocket and shares most of it's design with our current rocket. Unfortunately the parachutes never deployed and after impact with the ground nothing was salvageable from the vehicle.
LV2c is our current airframe. Everything on this page is about our current work.
Project: We're currently designing the LV2c airframe after our August 2005 successful-but-fatal launch.

- Track-Master 3000 - A servo-controlled base that can hold an antenna, camera or something that is other wise interesting and automatically point it at the rocket during flight and recovery. Bonus points if it can control focus and zoom on a camera with a giant lens...
- A better mechanism for aiming the wi-fi antenna on the tower, some kind of pan-tilt mechanism that is easily adjustable from the ground, avoiding the need to climb the tower
- Separation rings capable of holding larger motors, P-class, which are 6ft long and 5" in diameter. It would be good to test this under sheer, perhaps 10,000lbs of tensile strength. Also cool would be mounting the bottom half to a shake-table, and putting an arm with a weight at the top vertically to see how it holds up on the shake table with various moment-arms on the top of the separation ring.
- A servo control camera module, that can move a camera out from the rocket airframe and allow software to point the camera up, down or sideways depending on whats interesting
- Trailer Launch tower
- Setup/teardown by 1-2 people in 20 minutes
- Can hold some gear
- Can facilitate current rocket, and perhaps a rocket that is 20-30 feet tall in the future
- Can store in some minimum amount of space, perhaps it can be lifted on end and stored vertically against a wall or fence, optional
- Has some kind of arms that come off the trailer with jack screws, perhaps those used on boat trailers?
- Towable with a small vehicle, minivan or light pickup truck
- Tool supply lists and launch tower setup procedures can be found on the launchprocedures page
- The old LV2 page is here.
Note: This is infrequently used as a place to dump notes that we can't think of anyplace to put. It does not mean we are not busy or do not meet often!
