Hanna 2024

The Calgary Rocketry club hosted the Hanna high-power launch, on April 20, 2024.

Mega-Initiator rDDT

I was there to fly my Mega-Initiator rDDT, which is my Mega-Initiator DD modified for redundant dual deployment and fitted with a GPS tracking transmitter.

A redundant DD system uses two altimeters, two batteries, two arming switches, and two pairs of ejection charges. The hope is that if one system fails, the other system will save the day. Although you are only doubling the components in the altimeter bay, it is more than twice as difficult to wire them up correctly. Why bother? It is required in any rocket flown for L4 certification.

A GPS tracker is not required in any rocket, but high-power rockets can go very high and very far, often landing out-of-sight. The GPS tracker helps locate the rocket. Sometimes.

Flying on an Aerotech 54mm J250, my rocket climbed to 3076 ft. The rDD performed perfectly, but the GPS tracker died as soon as I turned my back on it! Luckily, my wife and I had seen where it landed, and we recovered it in perfect condition.

Fire & Ice 2024

The first high-power flight in Alberta for 2024, Fire & Ice was held in Viking by the Edmonton Rocketry Club.

Still needing one more high-power dual deployment for my Electronics Endorsement, I returned with my Highlander 29 DD. Flying on an Aerotech 29mm H135, it rose to 1525 ft and the dual deployment worked perfectly. The rocket landed on the frozen lake, about a five minute walk from here.

With my EE now complete, I could begin the L4 certification journey, a process not unlike ritual suicide…

Starting 2024 with a Bang!

January 24, 2024 was the date of the first ERC launch in 2024, and was held in Calmar.

I returned with my Black Tusk DDL, which had a “mostly good” flight and a “not too bad” recovery. The drogue deployed properly, but the upper airframe shredded when the main deployed. The remainder of the rocket was recovered, except for the nosecone.

Nobody ever said that dual deployment was easy…

Final Launch of 2023

The ERC held their last flight of the year at Calmar, on November 12, 2023. It was actually quite a nice day, no wind and mostly blue sky.

My Black Tusk DD had failed it’s previous dual deployment attempt because the main parachute was too tightly packed into the upper airframe. I replaced the old tubing with a longer one, creating the Black Tusk DDL.

Flying on a CTI Pro29 G126, it reached an altitude of 1279 ft. It was a perfect dual deployment flight, using my EasyMini, and a great way to close out the year!

Fall Fire 2023

On October 14, 2023, I attended the Fall Fire rocket launch in Kitscoty, Alberta, hosted by the Saskatoon Rocketry Society.

In Canada, it is necessary to obtain an “Electronics Endorsement” before starting the L4 Certification process. This requires two, high-power flights using dual deployment in a different rocket for each flight.

I modified my Aerotech Mega-Initiator, adding an altimeter bay and an upper airframe tube for the main parachute. This flight reached an altitude of 1352 ft on an Aerotech 29mm I205. Everything worked perfectly, under the control of an EasyMini altimeter (primary) and a RRC3 altimeter (backup).

My second flight used the Highlander 29 DD, reached an altitude of 931 ft, but the main parachute hung in the airframe. The rocket landed safely on the drogue, and was prepped for another flight. This time, the rocket rose to 895 ft, but the drogue did not fire until about the same time as the main chute. Inspection revealed that the drogue was not properly armed, and was ejected by the motor ejection charge instead of by the StratologgerCF altimeter.

Even though I only completed one of my two required dual deployments, it was a learning experience and I had a good time. This was my first Fall Fire, and I really enjoyed meeting the local rocketeers.
