Hammerhead Shark.. The Rocket
This scratch build started as a result of seeing an Apogee Skonk Wulf and thinking that it looked more like a shark than a Nazi weapon of war.
Then when I was making the drawings for the rocket I saw a "Shark Week" slot machine that had a Hammerhead Shark and thought.. hmmm that would be cool. The build has been really fun. It's got fin tabs and papered fins. I tend to build more for durability than altitude. It sim's in Open Rocket just fine. I tried my best to make the hammerhead neutral.. meaning not an airfoil that would pitch the rocket. So tell me.... what do you think? |

Pretty cool, as long as the forward area doesn't hurt stability.

What kind of wood did you use for the NC/head? It will need nose weight unless you used dense wood. Looks cool. Are P-40 shark teeth and eyes in its future?

It's pine, and it will still need additional nose weight. 6.5 ounces per the Open Rocket simulation. Not sure yet about the Walt Disney teeth... |

With all that weight up there, and disruption of airflow over the fins, it would be cool if it wiggled side to side like a swimming shark. I'm afraid if it does wiggle, it will be more like a porpoise, but it's going to be a nice model, regardless. Looking forward to seeing it finished!

The only way to make the hammerhead neutral, or mostly neutral, would be to make it pivot.
The way it is now, if the rocket pitches up or down during flight, I am concerned that the hammerhead is likely to push it all the way over. I mounted a camera in the nosecone of a rocket so that it stuck out one side, sort of like half of the hammerhead. The rocket went straight up about four or five hundred feet then took a sharp right turn. I suspect it just happened to change its angle of attack so that the airflow hit the camera on its aide. The long distance between the camera in the nose and the CP acted like a lever multiplying the small force on the camera. |
