2023 Launch Reports

Jan   Feb   Mar   Apr   May   Jun   Jul   Aug   Sep   Oct   Nov   Dec

January, 2023

January 21 turned out to be an overcast day for the entire launch, but we still enjoyed a fun-filled day of rocketry. Following NAR rules, we required all rocket flights to stay below the cloud base, or approximately 2000-2300 feet. Although the low-lying clouds were a challenge, we benefited from calm winds as well as reasonably comfortable temperatures for this time of year, beginning the day in the low 20sF and gradually rising to the high 20sF by mid-afternoon.


The fields were frozen with 4-6 inches of snow on the ground and the large ditches had about 2 feet of water. Setup started about 0900hrs with Kevin K plowing the road down to the field to prevent vehicles from getting stuck. The low-power rack was set up at 50 feet from the launch table, and one blue high-power pad with an 8-foot standard 1010 rail at 100 feet. Later in the day, students from Northeastern University set up the large yellow pad with the 12-foot 1515 extreme rail also at 100 feet. Flights started at 1015hrs.


Kevin K collected annual dues from club members and launch fees from all fliers, while wearing a NAR range safety vest. Scott L provided GoPro views of liftoffs with the camera positioned right next to the launch pad, and James S video-recorded all launches from the flight line using a basic iPhone. John A, Kevin K, Paul S, and James S helped with RSO duties and certifications. There were five Level 1 certification attempts on this day, and three of those attempts were successful.


Flying started at 1015hrs with the FAA notified. By 1100hrs, attendance was 14 people, which increased to 19 by 1200hrs, including students from Northeastern University and Olin College of Engineering.


At 1540hrs, after a pleasant day of flying (albeit limited to 2000 feet altitude), we packed up the equipment and left the field. Five club members then had dinner together at Mill River, staying there until 1725hrs.

MOTORS:
We launched 22 flights on 24 motors, including a two-stage flight (Else and her Estes Nike-X on C6-0 to C6-5) and a cluster flight (Paul and his Thrustline Hank on B6-4 x 2). Together as a club, we flew 4104.9 Ns total impulse, which is equivalent to a medium-sized L motor. The mean impulse was 171 N, which is a small H, and the median was 110.2 N, which is a medium-sized G motor. The mode was G (7 G motors). The distribution of the 24 motors was as follows:
A: 0
B: 2
C: 4
D: 1
E: 2
F: 0
G: 7
H: 3
I: 5

March, 2023

SETUP
Club members began arriving on the field at 0900 hours, and Kevin K drove his truck with club equipment down the farm road to the launch site. Due to slushy snow and ruts on the farm road, we decided not to allow any other vehicles to go further down the road. We set up the parking area at the crest of the hill on the south side of the farm road. About 20 vehicles parked there or else farther west along the farm road. We set up our launch site at the bottom of the hill (west side of the cornfield). The two blue HPR pads were positioned at 100 feet from the LCO table, with extension cords available out to 300 feet. The low-power rack was placed at 50 feet. Later in the day, the large yellow pad was installed at 300 feet for larger flights. We were ready to begin flying at 0951 hours, and the first rocket lifted off at 1045. The last rocket was launched at 1610 hours, and we finished packing up equipment and left the field. Six club members had lunch together at Green Mountain Cafe in St. Albans.


ATTENDANCE
Seven club members attended the launch along with about 40 college students from Northeastern University and Worcester Polytechnic,as well as several guests. At least two of the guests had learned about CRMRC one week earlier at the St. Albans train show, where Howie D., John A., and Paul S. hosted a display about our club.


CLUB DUTIES
Howie D and Kevin K served as LCO and RSO. Kevin also collected launch fees and distributed CRMRC nametags for members. James S. video-recorded flights. Scott L. provided GoPro closeup views of some launches, and Curtis H. set up his RocketTrig system for additional photography (as featured in a recent issue of Sport Rocketry).


WEATHER
At 0900 hours, the field temperature was 33 degrees F, and we notedoccasionalwind gusts up to 15 mph. Skies were fully overcast during the morning and the cloud base was estimated to be 3000 feet (verified with launches).Because of this cloud layer, we limited all flight configurations to maximum 3000 feet apogee, following NAR rules. The clouds began dissipating slightly around noon. Then at 1500 hours, the sky cleared significantly, and we enjoyed blue sky and largely sunny conditions for the remainder of the launch day. The field temperature gradually increased during the day, reaching 39 degrees by 1600 hours, while the wind gradually decreased. We observed an average wind speed in the range of6-9 mph at 1023 hours, then0-3 mph at 1100 hours, and 5-12 mph at 1600 hours.


FIELD CONDITIONS
Some of the ditcheswere filled with several feet of water, and the cornfield had a layer of slush and water which required waterproof boots. However, underneath this wet layer in the field, the groundwas stillfrozen so we did not have any major problems with mud.


MOTORS
We flew 22 flights on 28 motors, including 4 cluster flights (see Curtis H. below). The largest motor was a CTI L1050BS with 3727 Ns impulse. The smallest motor was Estes C6 with 8.8 Ns impulse. As a club, we flew a total of 11814.1 Ns total impulse, which is equivalent to a small N motor. The motor distribution was 6 C, 2 F, 6 G, 2 H, 7 I, 4 J, 1 L. The mode of this distribution was I (7 I motors). The mean impulse was 421.9 Ns oran I motor. The median was 136.7 Ns or a G motor.

April, 2023

This was a large and busy club launch attended by about 60 people, including 13 CRMRC members, three large teams of college students from Northeastern University, Worcester Polytechnic, and Tufts University, as well as numerous other visitors. There were a total of 58 rocket launches, including eleven successful certification flights (seven Level 1 and four Level 2).


Club members arrived on the field about 0900 hours and began setting up equipment. Kevin K, John A, and Howie D brought club equipment in their vehicles. We set up the low-power rack at 50 feet and the two blue pads at 100 feet with 1010 rails and 1515 rail available, with an additional extension cord available at 200 feet for K flights. Later in the day, the large yellow pad was set up at 300 feet (1515 rail) for L flights, and an additional string of extension cords was connected to that pad.


We were ready to fly by 0930 hours, and the first rocket lifted off at 1009 hrs. The last rocket lifted off at 1709 hours, so we had exactly 7.0 hours of flying time. Kevin, John, and Howie managed certifications. James recorded launch videos from the flightline and took photos of rockets on the pads. Scott L. recorded GoPro launchpad views. The LCOs were Howie, Kevin, Doug, and Paul. RSO work was handled by Howie, John, Kevin, James, Doug, and Paul.


The weather and field conditions were near perfect throughout the day: mostly clear skies, low winds, and no standing crops in the fields. At 1030 hours. we observed that the average sustained wind was only 2.9 mph, with max gust recorded at 8 mph. Since the wind was generally quite low near ground level, many rockets landed conveniently near the launch site. At higher altitudes, we observed winds at approximately 10-12 mph from south or southeast, and so a few rockets drifted into the second fields to our north and northwest, but those rockets were easily recoverable as well. Temperatures were in the low 60s F in the morning but much warmer in the afternoon (vehicle thermometers registered high 80s to 90 degrees at the end of the afternoon).

MOTORS:
We flew 58 flights on 62 motors. The total impulse over the day was 37,549 Ns, which is equivalent to a very large O motor (92% O). The mean was 606 Ns (I motor), and the median was 212 Ns (H motor). The mode was H (20 H motors). The motor classes were distributed as follows:
A: 0 motors
B: 0
C: 4
D: 2
E: 4
F: 6
G: 7
H: 20
I: 2
J: 8
K: 5
L: 4
Total: 62 motors

May, 2023

Due to poor weather, the May launch was postponed one week to May 27, 2023. This was Memorial Day weekend so as expected, attendance was lower than our typical turnout. Nevertheless, there were 25 flights. The weather could not have been better. Sunny with low winds and temps in the upper 70's.

The corn crop was planted with seedlings only 3 inches high, enough to see them and avoid trampling. The last flight was at approximately 3:30 PM. At around 4:15 PM remaining group members headed off to Mill River Brewing, BBQ & Smokehouse for a meal and conversation.
