Fortuna 2

Summary

Fortuna 2 is a small single stage rocket designed for the testing power level of smaller consumer engines, as well as how well materials such as hot glue can withstand the heat of small engines.

Flight Reports

Flight 1

On June 8, 2014, Fortuna 2 was launched. Fortuna 2 is a 1 stage rocket, that was testing how mimi engines compared to standard size engines. As expected, Fortuna 2, using a A3-4T, didn’t gain as much altitude as Fortuna 1, most likely because of the difference in engine size. The both flew at approximately the same angle, ESE, so the only difference was the amount of black powder, thus making the altitude the engine is capable of different. The other test was to see how hot glue would stand up to the heat of an engine that is ignited. My hypothesis was that is would melt, but after looking at the hot glue over the engine, the glue was only slightly burnt. After Fortuna 2 was launched, the rocket flew up, spiraling rapidly, probably because of the nose cone. 3 seconds after the the engine cut off, when the nose cone was supposed to pop off, the nose cone didn’t. This was one of the major concerns of the rocket, as the nose cone was a very tight fit. Since the streamer didn’t deploy, Fortuna 1 nose dived very fast, and once the rocket hit the ground, the nose cone was pushed about 0.5 cm. into the fuselage of the rocket. After looking into the inside of the rocket in the laboratory, there were little pieces of black powder and clay in the fuselage, from the engine.
Overall outcome: Slight success

 

Flight 2

On November 28, 2014, Fortuna 2 was launched for the second time. Fortuna 2 was testing how small parachutes work with rockets like Fortuna 2. The material of parachutes used on Fortuna 2 are known not to function properly when the weather is under 4.4 degrees celsius. Other parachutes are currently being looked into. When Fortuna 2 was launch, the rocket spun away from the launch pad. It continued to do several more loops until it landed 15 meters away from the launch pad. The parachute did not have time to deploy in flight. It is estimated that when Fortuna 2 was at its apogee, it was at an altitude of 15.37 meters.

The cause of the flight failure is unknown. It may have been because of an off balance nose cone, as some changes were done to that part of the rocket. The nose cone was fitted very loosely, and may have tilted off of the center point. Another possible cause could have been that the fins were made out of cardboard, and they were not completely vertically to the ground at the time of the launch.

Despite the overall failure of the launch, Fortuna 2 will not be taken out of service, because it is the only rocket that uses mini engines, and a rocket is not foreseen to be made to accommodate mini engines for a long time. The nearest time would either be in the 3rd section of the Fortuna series, or when in an individual mission that is not part of a series. There is a very small chance for the rocket to be made outside of the series as almost all of the work from the SFSA needs to be focused on the Fortuna Series as it has the most potential.

Flight Outcome: Failure
