Flight Reports

Flight 1

Fortuna 1, the first rocket in the Fortuna series, launched on June 8, 2014, on about 10:30 A.M. at Yankton Trails. At the time, wind was blowing at about 8 kph west. Moments after launch, Fortuna 1 flew ESE, about 10 degrees. Since Fortuna 1 tilted about 10 degrees, that succeeded the test. Although later that day, Fortuna 3 was launched, with the same cone design, and spun out of control, tilting close to 80 degrees. Because of the cone failure of Fortuna 3, a new nose cone design will be issued. After Fortuna 1 reached its apogee, Fortuna 1 started to lose altitude. A few seconds later, the nose cone popped off. The streamer partially deployed. Fortuna 1 fell to the ground very quickly, but after looking at the rocket, no damage was done. Part of the streamer melted together, but still deployed, so aluminium foil could be used as recovery wadding. After the streamer was examined, part of the streamer, about 4 cm. from the shock cord, the streamer is about 90% melted through.

Overall outcome: Success


Flight 2

On July 29, 2014, Fortuna 1 was launched for the second time, about 1:00 P.M. Fortuna 2 was launched at the cross country course of the University of Sioux Falls. Immediately after launch, Fortuna 1 flipped over at an approximate height of 20 meters, and, while the engine was still burning, accelerated towards the ground very quickly. Fortuna 1 crashed into the ground, damaging the nose cone, and crumpling the front part of the fuselage. All 4 fins had slight damage at the tips. That is not thought to be the cause because there was very slight damage, An engine failure could not have been the cause either, because after examination, there were no flaws on the engine. What could be the cause is a very sticky launch rail. After recovering Fortuna 1, it was noticed that the guide straw was shattered. That could have happened moments after ignition, on the launch rail, or it could have been from the crash. Another, more probable reason would be that the nose cone was off balance, causing the rocket to tip over. Because of this, Fortuna 1 is going to be retired from service. Fortuna 1 may not be flown again.

Flight Outcome: Failure
