SLU Rocket Propulsion Lab's Rocket Engine Test Fire in Columbia, Missouri

We will be test firing our new O-Class engine producing 1400 pounds of thrust for 6 seconds. This will be our first full scale motor test for our April and June competitions and will give the group an opportunity to measure thrust and chamber pressure.

Time Schedule

Arrival 11:15am
O-Class Engine 11:30am
End Time 12:00pm

Cesaroni Technology Inc., manufacturer of high-power rocket motors, has announced that there is a known problem with the forward closures on some Pro38 reload kits manufactured between October 2015 and January 2016. If you are a user of CTI Pro38 motors, please refer to CTI's bulletin (http://www.pro38.com/pdfs/Bulletin-Pro38_Forward_Clousre.pdf) for details and instructions for replacing the affected parts.

[I apologize for the February meeting announcement which got sent to some of you - obviously an error.]

The third and final post from last night's meeting is the R&D paper presented at a past NARAM entitled "Development of a Series of Rocket Gliders for 1/4A Through G Power." John brought a D motor powered example of his design, which is pictured below, and made the paper available to our members. Thanks, John!

Figure 1: D Rocket Glider in launch configuration. The motor pod is held in place by a string which passes over the motor's ejection charge.

Figure 2: D Rocket Glider in glide configuration. After the ejection charge burns through the string, a rubber band pulls the motor pod back.
