Американская команда запустила двухступенчатую ракету на 31,900 метров, получив данные с GPS и прямую трансляцию с ракеты:
To our rocketry colleagues:
This is our notice of a successful attempt to claim the Carmack Prize for an amateur flight above 100K'. Our flight on Tuesday 9/11/2012 reached 104659' AGL as verified by both the onboard Beeline GPS as well as APRS telemetry from the airframe that was streamed in real-time to the APRS database. The flight track for the sustainer is at KG6DLV-4 and the booster is KG6DLV-5 at aprs.net.
The airframe is a two-stage, minimum-diameter design. Construction is primarily of commercially-available fiberglass components with carbon-laminated fins.
Architecture: Two stage minimum diameter - 4" booster to 3" sustainer
Motors: Commercial motors. Aerotech N1000 in booster staging to Aerotech M685 in sustainer. 25 second total burn time.
Total impulse: 21,650 ns
Pad weight: 61 lbs
Avionics: (Raven+RDAS, Beeline GPS (70cm APRS), GoPro2 + WiFi BacPac) replicated in booster and sustainer
Payload: Smartphone+sensors with 2m APRS telemetry
Launcher: 12' rail
We flew at Black Rock, NV, during the AeroPac ARLISS and XPRS events, September 11, 2012. We had full recovery of the airframe within 6 hours - both booster and sustainer. We flew the same stack today, Thursday 9/13/2012 on an N1000 staging to a CTI M840. However, the CTI motor failed - while it burned completely it generated no thrust. The airframe was again recovered intact and flight ready. We intend fly again with a replacement sustainer motor on Saturday 9/15/2012 and plan to again webcast the video of the launch as well as real-time telemetry of the flight from the AeroPac web site (http://www.aeropac.org)

The GPS flight track of the sustainer is enclosed.
The GPS flight track of the booster is enclosed.
The first flight was imperfect with loss of the forward rail guide causing off vertical flight for the full stack and subsequent off vertical staging. Despite that, the sustainer attained the 104k' AGL altitude. We have modified the airframe rail guides and the second flight today was satisfactorily vertical.
