- **Adaptable Airframes** - Instead of making a patchwork of balsa wood and cardboard, we're working on a system that uses modular, <font>machined-aluminum airframe sections</font> to reduce weight and cost but increase adaptability. Airframe sections are easily swappable and will be covered with a thin composite skin. In rocket speak, we're trying to push our <font>mass fraction</font> up as high as possible - beyond 60% for a single stage vehicle - while still maintaining robustness.
- ![](/psas/Resources/graphics/omotor3.JPG)**High Energy Motors** - Given the number of launches we would like to do in the future, we are developing our own motors. Using an industry standard Ammonium Perchlorate/Aluminum composite formula, our solid rocket motors are in the <font>10K-60K N-sec range</font>. In the future we'll move to hybrids for their safety and controllability.

2. [Launch Vehicle No. 1](/psas/Current_project/LV-1/Lv1menu.html) (LV1) was our next rocket that flew in April of 1999 to 3.6km (12,000ft). It was our proof of concept for several new systems, including a manual control system, inertial sensors, and a more advanced telemetry system [(Launch Results and Videos)](/psas/Schedule/Bend4_11_99/Bend4_11_99.html).
3. <font>Launch Vehicle No. 1b</font> (LV1b) was the same rocket as LV1, but with improved avionics (electronics) which flew in October of 2000 to 3.53km (11,600ft). We added a GPS, upgraded the flight computer and improved the inertial sensors. This was our first real stab at the computing power and sensors necessary to do computer guidance; we're right in the middle of processing the data from this launch and are excited about its implications [(Launch Results and Videos)](/psas/Schedule/Bend10_7_00/Bend10_7_00html.html).
-We've also developed "M"-class <font>solid motors</font>, test stand equipment for motor testing, and the beginning of a mobile infrastructure including a [launch tower](/psas/Schedule/Tower/Launch_tower.html), a <font>launch control module</font>, and the various logistical equipment and skills a group needs to do successful field operations.

We also try and reach out to the community as much as possible. We're a regular attendee at [OMSI's Space Days](/psas/Schedule/OMSI/OMSI99.html), we've done many educational presentations and we're an advocate of cross-discipline engineering projects at Portland State.
-**_What are your current projects?_**
+## <a name="What are your current projects?"></a> What are your current projects?
We're currently working on the next generation vehicle, called [Launch Vehicle No. 2](/psas/Current_project/LV-2/LV2menu.html) (LV2) which should be ready to launch in fall of 2002. It has a projected altitude of 21km (70,000ft), has an advanced avionics system which we hope to use for real computer guidance, a modular air frame system, and most of all it'll build on everything we've learned from the last three rockets. LV2 is currently funded through a $10,000 grant from the <font>NASA Space Grant Program</font>.
-**_What's your ultimate objective?_**
+## <a name="What&#39;s your ultimate objective?"></a> What's your ultimate objective?
We have a "vision statement" - i.e., a goal which we're heading towards but may not reach as a small univesity club. Our vision is to put "<font>Nanosatellites into Orbit</font>". In other words, we want to put very tiny little satellites (think something on order of a coke can) into orbit around the Earth. That's a very hard, expensive and time-consuming thing to do; it's very possible that we may never reach that goal. But that's ok; we're taking the small steps necessary to get there, and for us the journey and the learning is all part of the fun.

Absolutely! We need the help!
We're looking for anyone who is interested in space or technology, people who have a love for seeing a complex system come together. There are tasks from control theory analysis to airframe design to computer programming to logistics support that we need help with. [[Contact us|Contacts]], or drop in on [[one of our meetings|Schedule]], and we'll integrate you into whatever you're interested in doing within the context of the PSAS.

This site contains all of the information we have on our project. We do have printed materials available for donors, press, and potential payload developers; please [[contact us|Contacts]] if you're interested in this.
