Member Meetings


April’s meeting is going to be a busy one! We don’t just have one but two special presentations. Definitely a meeting you won’t want to miss. 

UROC member Doug Hillson will present the results of research and analysis related to wind speed at different altitudes and how to use this information to predict rocket landing location. Doug wrote two articles on this topic for Sport Rocketry Magazine. Doug will discuss taking the best estimates of wind speed and direction at different altitudes, based on ground measurements, to predict the landing location of a rocket.

Doug will discuss theory of the planetary boundary layer and on using the currently available information to make a best estimate of landing locations during a rocket flight by utilizing publicly available wind data. Data collected by the Army Research Laboratory at the TARC finals in Virginia in 2007 and 2008 was analyzed and will be presented. Doug also spent the last two years at Endurance Wind Power in Spanish Fork, Utah among other things collecting and analyzing wind data, so he’ll speak to the state of the art in measuring wind speed.

Doug recently moved out here from the east coast and was originally a NOVAAR member, he has been flying rockets since 1992. Occasionally when he flies rockets there’s slight proof that he actually has an engineering degree.  

We will also have UROC member Kip Daugirdas give us a presentation about his recent launch to 145,000 (yes, that is one hundred and forty-five thousand) feet at Balls this past September. This launch was captured on video and had a full recovery of the craft. The rocket was a two Stage 4” booster to 3” sustainer weighing in around 60 pounds and was powered by an N-2500 in the booster and staged to an M-685 in the sustainer.

In addition to these great presentations,  (Thanks Kip and Doug for being willing to help out!) we will have our regular show and tell and talk about the upcoming UROC events.

Please arrive on time and plan for a full night!
