Ultralight Rocket

thingiverse

The "Need for Speed" rocket design was conceived following a trial of the "Modular Rocket" from Thingiverse [http://www.thingiverse.com/thing:8754]. A video of this attempt can be viewed here: [http://youtu.be/4qqQSMpU9F8]. Inspired by the Rostock Max's height, a towering rocket was envisioned with the largest hobby shop engine packed in a slim profile. However, this design remains untested; fly at your own risk and be aware of potential failures listed below. Key specifications include a length of 1.3 meters, a 26mm outer diameter and 25mm inner diameter, a width of 57mm, an engine size of 24mm by 93mm, and an unspecified weight. The design was created using Tinkercad and can be accessed here: [https://tinkercad.com/things/8Yjxvd6FzVC]. Printing on a Rostock Max printer with approximately 13.5" tall segments is recommended, accommodating an Estes E class engine or potentially a D-class with a spacer. The nose cone requires weighting with clay to balance the center of pressure and ensure stability during flight. As this design has not been tested, proceed at your own risk. Several potential issues could arise, including: 1) the initial pulse compressing the nose cone's weight, causing it to break and fly uncontrollably, posing a high risk of injury; 2) dynamic pressure and vibration during flight potentially causing disintegration, resulting in an uncontrolled fincan and falling debris, with a moderate risk of injury; and 3) the ejection charge's pressure possibly rupturing the tube but occurring at apogee, reducing the likelihood of falling debris. Other risks cannot be foreseen, but there's also a possibility that the rocket could fly flawlessly.
