Tiger II
Tiger II on Launchpad
Tiger II was the very first rocket that I developed.
CAD
Structure
Tiger II is completely 3D-printed and can utilize any number of engines between one and four. It consists of several sections that can be plugged into each other. The individual modules are glued together to further secure the connections between the different prints.
As this is a standard model rocket using passive stabilization, fins would commonly be added to the rear of the rocket. In this design, the engine enclosure is responsible for the passive stabilization. The engine enclosure is symmetrical and enlarges the rocket area at the rear, which in combination makes up a good passive stabilization system.
Launchpad
The launchpad structure is the exact negative form of the engine enclosure, allowing the rocket to rest easily on the pad.
Below the pad, a 3D-printed part accommodates several matches that extend out on one side. By igniting the extended matches on one side, they slowly burn toward the rocket engine until it is ignited, ensuring a reliable and controlled launch process.
Launch
Tiger II was launched twice.
First Launch: The rocket utilized a fast-burning engine. You can see the video of the first attempt below.
Second Launch: A slower-burning engine was used. However, this resulted in instabilities during flight due to decreased functionality of the passive stabilization system.
